For what projects/services did your company hire Selleo, and what were your goals?

We hired Selleo to develop our digital marketplace that connects schools with teachers. Our goals were to build a world-class web and mobile experience. The recruitment industry for schools are very traditional, so we wanted to digitally transform the way the industry works. We chose Selleo as our development partner in that journey.

We could not be happier with the collaboration overall. They take full ownership of their work and always use the best tools available while maintaining high security and scalability. The communication with the team is transparent and the entire project is based on mutual trust and openness.

The collaboration with Selleo gives us the opportunity to be an agile company that quickly can adapt to new possibilities and test new ideas. When it comes to measurable outcomes: Humly have seen a 4x revenue growth since Selleo joined as our development partner. We are now the leading supply teacher provider in Sweden and are ready to grow to more markets.

Describe their project management style, including communication tools and timelines.

We meet every day for a standup. We work on a biweekly sprint basis, so every other week we plan together what to do next. Selleo has a tech lead that also works as a project manager, which we have found to be a very important and good role in a project like this. All planning and follow up of the progress is done with the tool Trello.

What did you find most impressive or unique about this company?

Selleo has vast experience in building scalable, high-quality solutions for businesses in various industries. Their process is Scrum-based, which ensures everybody remains up-to-date with the latest improvements. Their technical expertise keeps inspiring me, but, above all, they are simply great people to work with. I highly recommend Selleo as a development partner. We couldn’t be any happier.

Are there any areas for improvement or something they could have done differently?

I honestly don't think so. The delivery is of high quality and communication is very good. Of course, there are some bugs sometimes, but it's a complex project with many moving parts, and the team is always very quick to catch and adjust the bugs.

We run large sports leagues, community events, brunches, and more in cities all throughout the United States. I'm the CEO.

For what projects/services did your company hire Selleo?

We initially contracted with a terrible company that tried to massively overbill us and did next to no work - they were completely incompetent. Selleo came in and rescued the project and saved the day. Then, when the pandemic hit, they helped us pivot and worked with us. We're now in good shape when it seemed like we would never finish the project before.

What were your goals for this project?

Create a complex rails app that would allow us to run our businesses as scale.

How did you select this vendor?

We interviewed all the top Polish and Ukrainian Rails developer firms. Selleo treated us like an intelligent partner rather than trying to sell us with telling us everything we wanted to hear or making vague promises. They brought in the lead dev the first meeting and we met with them numerous times before starting the project. The dev gave us a great plan rather than a cookie cutter one. We decided to go with Selleo.

Describe the project and the services they provided in detail.

They planned, setup architecture, and developed the site - as well as doing dev ops. In short, they did everything we needed to get the app/website up and running and launched.

What was the team composition?

Lead dev, three other rails devs and a designer/frontend dev

Can you share any information that demonstrates the impact that this project has had on your business?

Still ongoing, but the difference between them and the previous teams we've worked with have been night and day.

How was project management arranged and how effective was it?

Project was managed by lead dev - we met once a week but the lead dev and I would chat throughout week via slack and sometimes would do one meeting a day. We used pivotal tracker to track progress.

What did you find most impressive about this company?

They have strong leadership, offer a good value, and they're flexible.

Are there any areas for improvement?

None for now

Selleo’s developers have become part of our team, performing a variety of development work for us. For the web component, their team built our scheduling platform with specific client tools, using React. For the application, they used React Native. The app we’re building is a checklist tool that assigns people tasks. They will be able to complete the checklist, report issues, and take photos that they can send back to their managers.

While we’ve rotated different team members, we typically work with three to four developers.

We were referred to Selleo by someone who was recruiting business for them.

We’ve invested between $300,000–$400,000.

What is the status of this engagement?

Our engagement with Selleo began in March 2017.

What evidence can you share that demonstrates the impact of the engagement?

Internally, it’s been nothing but positive feedback. Since they’re part of our team, we’re regularly reviewing their work. The developers go through the typical QA process that we have for our internal team. We discuss design, code performance & quality, and potential bugs.

How did Selleo perform from a project management standpoint?

From a project management standpoint, it’s pretty good.

What did you find most impressive about them?

We appreciate how invested Selleo is in our product. Their team strives to be part of our organization by learning our business. They’re excited about all of the projects we’re working on. It feels that they brought into what we’re trying to build.

Are there any areas they could improve?

They could pay a bit more attention to the broader platform of building and how the pieces that they’re working on are managed.

Do you have any advice for potential customers?

I think Selleo is excellent. I definitely recommend them.

Introduce your business and what you do there.

I am the CEO of a visual commerce company. We use phones to look at the world around you, included TV ads or programs, movies, print, or product packaging, to take consumers on a personalized digital journey.

What challenge were you trying to address with Selleo?

We needed developers to help create this platform.

What was the scope of their involvement?

Selleo is developing our progressive web app. We also have a SaaS API that goes into a brand’s existing mobile app. Their team works in Ruby on Rails and Javascript.

They ensured that the platform could ingest images, videos, and product shots to churn out a URL. The system captures data along the way to produce conditional logic-based offers. The program picks up keyboard languages, time stamps, and SKU codes.

What is the team composition?

We work with a permanent team of five from Selleo, occasionally scaling up. Sometimes when we have a specific project they’ll pull in somebody else for a short period of time. 

How did you come to work with Selleo?

We had worked with other developers in the past. After moving, I went on the hunt for Ruby on Rails developers, when we had previously worked in .NET. We interviewed three vendors, and Selleo was head and shoulders above the rest so we decided to work with them.

How much have you invested with them?

We have invested between $200,000–$1,000,000.

What is the status of this engagement?

Our ongoing engagement with Selleo began in June 2016.

Selleo has built some amazing things as of late. Everything we have collaborated on up to this point has allowed us to create new stuff. This platform is the first of its kind and we have been attracting some giant corporations to partner with.

How did Selleo perform from a project management standpoint?

They’ve been fantastic. Selleo works methodically and correctly, rarely making mistakes. They don’t overpromise, in fact, they probably overdeliver—and that’s a good thing. It’s rare to have someone that anticipates your needs. Their team has never missed a deadline.

What did you find most impressive about them?

The people blow me away, they’ve got a fantastic team. Everyone on their team is motivated and we all get on really well. After three years with the team, we still enjoy working together. The single most important thing is the people at Selleo and how we interact. 

Are there any areas they could improve?

No. I would have loved to have everything done in half the time, but that’s not a criticism of their work, that’s just the process. I’m very satisfied with everything Selleo has done for us. 

Do you have any advice for potential customers?

It’s important to test them and ask them questions. That will allow you to make sure it’s a good fit an also help both teams and uncover what the real commercial needs are. Selleo doesn’t just code, they understand what they’re coding and what the commercial implications could be. It helps to have a team that understands the commerciality behind what we’re trying to do because then they can offer the best advice that might save time or money down the line. That’s why our teams work so well together.

What were your goals for this project?

Develop a fresh and state-of-the-art solution, that allows all types of users to collaborate.

How did you select this vendor?

We started with an online selection, based on predefined criteria. After a couple of personal alignments with specific team members, Selleo started working on a limited scope proof of concept.

Describe the project and the services they provided in detail.

I needed a team to design and develop the entire SaaS platform together with landing pages and marketing collateral for the 9 teams They were responsible for app architecture, choosing the right technology stack (EmberJS, Elixir), graphic and UX design and development of all the features and functionalities.

What was the team composition?

I get the complete cross-functional team of six developers and designers and was able to modify the velocity based on the current business needs. There was a Team Leader who acted as a single point of contact for the product development and design team, and a Scrum Master who led the process.

Can you share any information that demonstrates the impact that this project has had on your business?

My development team worked for me full-time acting as if they were part of my in-house team. They were able to present complex technical challenges in the user-friendly way. I really enjoyed their engagement, proactiveness in helping me to develop product backlog, and caring about the business success as if it was their own project. They also depend on testing heavily and boost code quality to the highest standards.

How was project management arranged and how effective was it?

As regards the overall approach to managing software development projects, Selleo advocated to follow the rules and principle of Agile methodology. We decided Scrum to be the best solution with Scrum Master on their side and me in the role of a Product Owner.

What did you find most impressive about this company?

Deep integration and engagement between in-house and near-house team.

Are there any areas for improvement?

Of course. Areas for improvement are continuously identified. Good thing about Selleo is that they are actively working together with us to make both our processes and software better and better.

Introduce your business and what you do there.

I'm the CPO of Battleriff Gaming AB, an e-sports company. We started off focusing on wager matches within the gaming industry but have since evolved to become a leading community and rewards platform in the digital card game industry. Users can play games and compete on our platform with virtual currency which they can then exchange for rewards ranging from digital codes for games to physical goods like gaming hardware.

What challenge were you trying to address with Selleo?

We had extensive marketing and strategy experience internally, but we didn’t have a robust technical support team, outside of our CTO. The necessity of speeding up our development, especially regarding e-sports, pushed us to look for a technical partner.

What was the scope of their involvement?

They were responsible for front- and backend development of our platform, for which they used React and Ruby on Rails respectively. They also developed our full feature set including payment systems and a virtual currency with value behind it. As GDPR went into effect, they ensured our platform complied, since we didn’t have any expertise in that area. We also worked with 2–3 designers from Selleo who created the overall design of our platform.

What is the team composition?

We’ve worked with as few as two people and as many as six over the years. The team composition changes depending on our needs.

How did you come to work with Selleo?

I wasn’t really involved in the decision, but I believe our CTO had an existing relationship with them. He was familiar with their quality and knew they had gaming and e-sports experience.

How much have you invested in them?

We've spent between $200,000–$1,000,000.

What is the status of this engagement?

We’ve been working with them since January 2016.

What evidence can you share that demonstrates the impact of the engagement?

We’ve developed a significant amount of trust in Selleo, that they can deliver the velocity and quality we need. They understand our expectations at the beginning of every sprint and plan their work to ensure it's in alignment with ours.

How did Selleo perform from a project management standpoint?

Because we’ve been working together for so long, we don’t need to have constant communication. Trello lets them inform us as to what they require, and if they’re unsure about anything they always reach out for more information. We have the occasional weekly stand-up to discuss our current sprint, but after all this time we’ve become seamless partners.

What did you find most impressive about them?

They make everything easier on our side by taking on so many of the technical burdens. This includes everything from platform accessibility issues to new feature creation. While other vendors may simply create what we ask them to, Selleo lets us know if they have another interpretation. We value their opinion, and they respond by going the extra mile to optimize our product.

Are there any areas they could improve?

Sometimes when we need additional weekend support, we'll ask them too late, and they won't be available. Other than that, they go above and beyond to provide us with whatever we need, even if it isn’t strictly within their mandate.

Do you have any advice for potential customers?

Trust them and make an effort to include them in what you’re building. Their experience allows them to act like an in-house team if they understand your process. They’re an incredibly beneficial technical partner.

Introduce your business and what you do there.

I’m the managing director at WATTx, a venture startup company. We come up with and invest in startup ideas, build products, and work to get them to market.

What challenge were you trying to address with Selleo?

One of our projects was progressing well and moving quite quickly, but we lacked enough resources. Having completed some research and sketches, we needed to get a product up and running fast. Our client wanted to increase the pace, which required us to scale up our team.

What was the scope of their involvement?

We had wireframes, sketches, and the business idea prepared. Selleo helped us build a backend where we could integrate our data sources that came from one of our client’s external systems.  Using Python, they helped us create the data pipeline and make it reliable. 

We also needed to develop a dashboard for our customers’ clients. They helped us quickly build a React app. The corresponding desktop application that’s viewable on a mobile device as well. It’s fully reactive. At this point, we’re continuing to the next phase of the project and have also started a new one together. 

What is the team composition? 

Four people from the team worked on our project. The project manager they assigned us was our main point of contact.

How did you come to work with Selleo?

We researched a few different companies and reached out to our network to ask for agency recommendations. One of our employees also had some connections. He used to work with current staff members at Selleo and recommended their company. 

Selleo stood out based on the quality of the projects they had delivered. Their prices were very fair. Some offshore companies have cheaper prices, but also lower quality coders.

How much have you invested with them?

We spent between $50,000–$199,999.

What is the status of this engagement?

We started working together in August 2018, and the work is ongoing.

What evidence can you share that demonstrates the impact of the engagement?

Selleo did an exceptional job. Integrations with a corporate system are always a bit of a hassle, and they managed it very well. Of the six developers we’ve met so far, each one has been highly skilled and readily able to understand the goal of our projects.

How did Selleo perform from a project management standpoint?

They dedicated one person to project management. Initially, we were a bit skeptical about the need because we felt we could handle it ourselves. Our head of tech visited their offices for a few days to get them set up on the project and see their style of work. During that time, he met the project manager and thought she performed very well, so we decided to book her for some time. Our tech lead feels we learned much from her.

Our teams established a close integration. We had daily standups and reviews. They got to know the relevant business issues and understood what the project was about. Selleo always clearly communicated with us and we never had any bad surprises. They speak English perfectly. We beat the estimated timeline we set in the beginning. 

What did you find most impressive about them?

They have good quality code, and we like their approach. Selleo holds themselves to a high standard that I’ve rarely seen in agencies. They only deliver projects that are free of software bugs.  The communication between our teams is excellent. 

There were never any surprises because they communicated all the terms and costs. If anything didn’t go well, they openly admitted it. They quickly became part of our team, which helped us a lot.  

Are there any areas they could improve?

Their prices could be lower.

Do you have any advice for potential customers?

If you’re looking for high quality and want a reliable partner, I recommend integrating Selleo into your team. Provide adequate information to help them get deeply involved, and they’ll provide the most value. Their programmers and developers have a lot of experience and can really think for themselves.

If we didn’t specify something clearly, they asked clarifying questions and made useful suggestions. They’ll assign you team members that perform very well, work in sync with your team, and are invested in delivering the project.

Introduce your business and what you do there.

I’m the chief digital officer of Movinga. We’re an online-based company that offers moving services and more to customers in Germany, France, and Sweden. I lead our technical product and design department.

What challenge were you trying to address with Selleo?

We wanted to quickly ramp up our development capabilities and fill some gaps in our system.

What was the scope of their involvement?

They provided front-and backend development assistance alongside our internal team. We handled the conceptualization process and design elements in-house, and our project manager shared those requirements with the Selleo team. They implemented several UI changes on the frontend, working with Ruby on Rails and React.js. On the backend, the team helped us build logic into the grouping and dispatching system that’s used by internal agents working from desktop devices. They added a module to improve the backend system, which is also built with Ruby on Rails.

What is the team composition?

They assigned a frontend specialist, two developers, and a project manager to the project.

How did you come to work with Selleo?

Some of our internal staff had worked with them in the past, and they had good experiences. Based on that and their initial proposal, we chose to work with them for this project.

How much have you invested with them?

We spent between $50,000–$200,000.

What is the status of this engagement?

This project lasted from February–July 2017.

What evidence can you share that demonstrates the impact of the engagement?

They completed the development for the application, and it’s currently in use. We’ve worked with freelancers that weren’t that great in the past, but the collaboration with Selleo was pretty seamless. We didn’t run into any big hiccups because they were so well integrated into our team. We were very happy with their service.

How did Selleo perform from a project management standpoint?

Because he hired them to supplement our internal team, they didn’t have many project management responsibilities. Our team leads were in charge of scoping the work.

What did you find most impressive about them?

When we worked with other vendors, we had to go through several rounds of negotiations and back-and-forth discussions. It was a bit challenging. With Selleo, the entire development process was quite open and lean.

Are there any areas they could improve?

They provided developers from two different teams within their company, two from one team and one from the other. Selleo mentioned that they don’t normally split their resources that way, which I fully understand. They explained that they made an exception for our project because we specifically requested a frontend developer. We appreciated the accommodation, but the situation did create some limitations for us.

Any advice for potential customers?

Anyone considering Selleo should just send them an email.

Introduce your business and what you do there.

I’m the product delivery lead for a venture investment organization. We deliver funding to startups and are also building a number of software and services to support our ambitions in the venture investment space. I work with the delivery teams to make sure our software meets project requirements.

What challenge were you trying to address with Selleo?

We needed a robust and sizable partner to augment our pre-existing dev team and work on various software projects and products.

What was the scope of their involvement?

Right now, Selleo is building two web-based products. They use React to work on frontend development, and they also support our tech team who’s building the backend in Ruby on Rails.

What is the team composition?

They provide four full-time developers.

How did you come to work with Selleo?

We found them online. We narrowed it down to three firms, but Selleo had the best approach and was friendly, too. They were willing to discuss the project and make sure we all understood one another, so we hired them.

How much have you invested with them?

We’ve spent about £220,000 (approximately $279,880 USD).

What is the status of this engagement?

We’ve been partners since April 2017, and the work is ongoing.

What evidence can you share that demonstrates the impact of the engagement?

The products have minimal bugs, and I’m happy with the quality of their work.

How did Selleo perform from a project management standpoint?

We have weekly stand-up meetings to set expectations and go over progress. Even though they’re remote, they’ve engaged well with the project and have good communication. We use Google Meet and Trello to keep in touch.

What did you find most impressive about them?

They’re trustworthy and want the best for our organization. They’re eager for feedback and take it seriously, changing their workflow to meet expectations.

Are there any areas they could improve?

They sometimes need more oversight when it comes to implementing certain technology solutions.

Do you have any advice for future clients of theirs?

Treat them as part of your team and have regular communication. They work quickly, so make sure you have enough work to keep them busy.
