Feedback summary: 

Internal stakeholders are pleased with the MVP Puzzle delivered. Throughout the engagement, the team was collaborative, trustworthy, and reliable, contributing to a successful and enjoyable partnership.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m the founder and CEO of INgagedIN, a social network based on clauses and issues. We’re building engagement tools on top of the network, including for volunteering.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Puzzle?

We were building the platform from scratch and were looking for developers and designers.

SOLUTION

What was the scope of their involvement?

Puzzle developed our platform in Node.js. They designed the UI in InVision.

What is the team composition?

We’ve worked with 4–6 people from Puzzle.

How did you come to work with Puzzle?

We chose them for their knowledge, responsiveness, and empathy, the last one being an important thing for me.

If they weren’t able to put themselves in the shoes of the clients they were working with, things wouldn’t go well. They simply wouldn’t have an understanding of what we were doing.

How much have you invested with them?

The cost so far is $70,000–$80,000.

What is the status of this engagement?

We started working with Puzzle almost a year ago, and it’s ongoing. We have a long-term project.

RESULTS & FEEDBACK

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

The basic success metric was getting a working MVP, and Puzzle delivered that. Apart from that, we appreciate the level of trust and empathy, and the feeling that we’re working with people who know what they’re doing.

How did Puzzle perform from a project management standpoint?

I have two main contacts on their end, both of which are outstanding.

What did you find most impressive about them?

Puzzle stands out in terms of knowledge, responsiveness, affordability, and empathy.

Are there any areas they could improve?

There was the occasional typo or misphrase in their work, but this is understandable given that they’re not native English speakers. This occurred only with feature naming, because I provided all the content. It’s the only improvement I have to mention. I have no complaints about Puzzle in terms of the work they did and how they interacted with me.

Feedback summary: 

The Puzzle (formerly NextDots) team fit in seamlessly on the project and wrote near-perfect code that executed as needed and consistently met the customer’s standards. Communication between project managers was strong, and work was accelerated when necessary to keep the project moving according to plan.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m the CTO of a development company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with NextDots?

During a busy time, we needed to find some additional developers to help us take on the job.

SOLUTION

What was the scope of their involvement?

The app they partnered with us on is medical-related. We handled the design and project management work, but they were responsible for the frontend of the React Native app. Essentially, they integrated into our team and collaborated with our designers, project managers, and backend developer. 

What is the team composition?

They have a project manager on their side that coordinates work for their developers.  

How did you come to work with NextDots?

The outsourced provider that we typically partner with was also in a very busy work season. So, we divided to reach out to them for this project. We kept an eye on them early on, but things seemed to run very smoothly with them. We decided to keep them on. 

How much have you invested with them?

We spent about $30,000–$40,000 and have an upgrade on the way for the project.  

What is the status of this engagement?

We’ve been working with them since March 2020.

RESULTS & FEEDBACK

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

We’re just about to deliver the project and are happy to say that everything went according to plan. They delivered high-quality code that required very little QA. It was easy to work with them, and they were able to provide exactly what we were looking for. We have high standards for work internally, and they continuously met them. 

How did NextDots perform from a project management standpoint?

Their project manager is communicative and frequently communicates with our project management resources. When needed, they also ramped up to speed on projects to deliver according to our deadlines.  

What did you find most impressive about them?

Their code and quality of work are very high and need very few edits. That’s pretty unusual.

Are there any areas they could improve?

There was some turnover with their developers, so it would be great to see some more consistency there.  

Do you have any advice for potential customers?

Use Slack, that sense of frequent communication across our teams helped because they were very responsive. Make sure you work them into your schedule and are aware of any upcoming holidays on their end.

BACKGROUND

Introduce your business and what you do there.

What was the scope of their involvement?

They worked in Native Android to create our mobile application.

What is the team composition?

There were two people involved in this project.

Feedback summary: 

The app has yet to launch, but Puzzle (formerly NextDots) has met every deadline and delivered quality results so far. The team stays in constant communication through instant messaging services and provides valuable insights to further improve the final product.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I work in a fashion retail company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with NextDots?

I was trying to create an app that could merge our physical business with online sales. We started with it, and it was complicated at first. We worked with different companies until we found Next Dots.

SOLUTION

What was the scope of their involvement?

I don’t know much about the technicalities but it is an e-commerce app with a QR code. The app allows the client to check on the stock of the store, and it is a multi-brand app. We would also like to add other technologies such as AR/VR and RFID.

It is an Android and iOS app, but it hasn’t been launched yet.

What is the team composition?

We have worked remotely with them. I am directly in touch with the project manager only, but I know there are more people involved.

How did you come to work with NextDots?

I knew about them through another company I worked for before.

How much have you invested with them?

We’ve spent around $9,000 USD. I had part of the development done, so their work was mostly focused on the user experience, integrations, etc. 

What is the status of this engagement?

I started working with them in September 2018, and we are still working together on integrations.

RESULTS & FEEDBACK

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

We haven’t been able to measure any results as the app hasn’t been launched yet, but the results have been good so far. 

How did NextDots perform from a project management standpoint?

We have direct communication via WhatsApp and another app to create milestones and follow up on the project. All deadlines have been met, but we still need to make some adjustments.

What did you find most impressive about them?

NextDots has made some very good suggestions for improving the UX. We came up with a structure together, but their advice allowed us to make it even better. Also, the communication has been great. 

Are there any areas they could improve?

Not really. If the app hasn’t been launched yet, it is because of agreements we have to make with other fashion retail companies: this is the only reason why it has taken longer.

We needed help with development.

What was the scope of their involvement?

We had two projects with NextDots. The first one was to increase the number of developers we had, specifically for front-end development. The second one was to speed up certain developments we had.

NextDots mainly develops in React Native. They have a great deal of experience developing frontends for hybrid apps.

What is the team composition?

We work with three people.
