Sigma Software has served as the development arm of a startup that seeks to facilitate college financing. They’ve developed websites and have integrated custom software. They’ve also provided SEO guidance.
Sigma Software has secured an ongoing collaboration with the client, who has commended them for their ability to keep projects moving at a rapid pace. They’ve provided valuable insights, even when the matter at hand is outside of their scope of work. They’re a reliable and knowledgeable partner.
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 of College Finance Company. We help college students and parents find ways and strategies to better save, borrow, and pay for college. Our business launched just six months ago.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Sigma Software?
We’re a lean business without in-house developers or product managers. We needed a development partner who would help us launch our website. We also needed help in building some software.
SOLUTION
What was the scope of their involvement?
We’ve done several interrelated projects with them. They designed and deployed a WordPress website, and then provided consulting to help us maximize its SEO performance. Sigma built custom tools and interactive features — like a savings calculator — and integrated these into the site. I believe the site is hosted on AWS.
What is the team composition?
We have a project manager who is our primary point of contact. She organizes and delegates tasks to designers and developers in the team. We also interface with an account manager who helps scope out our projects with them.
How did you come to work with Sigma Software?
They were a referral by a friend of mine, who also owns a startup. He had successfully worked with Sigma and highly recommended them. I got to know them through that introduction.
How much have you invested with them?
We’ve spent around $65,000 so far.
What is the status of this engagement?
We’ve been working together since May 2020 and have an ongoing partnership with them. They’ve essentially evolved into our development arm.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
Sigma Software has been a dedicated, proactive partner. They don’t hesitate to give us guidance in areas that are outside of their strict scope of work, and we’ve benefitted from their insights. While we rely on another agency for SEO, Sigma Software gave us recommendations on how to further improve our positioning. We immediately benefitted from their input.
Additionally, I’d say that they’re excellent at managing me to make me a better client. They’ll look for ways to help me be most efficient and active in my execution. I’ve really appreciated their support and insights, in that way.
How did Sigma Software perform from a project management standpoint?
Our project manager is very good; she has a full command of design considerations, technical components, and SEO, so she’s very efficient to deal with.
We receive weekly summaries of progress, and their constant engagement ensures that they’re never the ones slowing us down. It’s almost always the case that I’m the roadblock, and not them.
What did you find most impressive about them?
Their communication and client management have been exceptionally effective. I’ve worked with 7–8 software development firms and many, many individual developers. Usually, they neglect to give me the feedback I need to stay on top of things. Unlike them, Sigma Software has been excellent at keeping me on track.
Are there any areas they could improve?
Most of their team is located in Ukraine. Sometimes, we benefit from the time difference, but there have been a few occasions where I wished they were accessible in the same time zone. It’s not a big problem, by any means. It’s simply something I’ve been frustrated about, from time to time.
Do you have any advice for potential customers?
Set and try to be crystal clear about your expectations upfront — what you want from the project. They’ll be very proactive in making sure you achieve it.

Sigma Software developed and launched the functional version of a preconceived advertising platform. The assigned dev team now focuses primarily on bug fixes and feature customization.
The launched ad platform began generating revenue within 6 months, which might not have been possible if it weren't for the proactive involvement of the assigned project team. Another key strength is their flexibility with rapidly evolving requirements.
A Clutch analyst personally interviewed this
client over the phone. Below is an edited
transcript.
BACKGROUND
Introduce your business and what you do there.
Zapp360 is a software-as-a-service ad-based platform for local marketers. We sell and channel through local resellers looking to use digital tools in order to engage better with their audiences and drive traffic into stores, to events, or for the services they provide. I am the founder and CEO of the company.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Sigma Software?
We needed tech developers. We had scoped out a rough idea of what we wanted to bring to market but had no technical skills to build the actual product.
SOLUTION
What was the scope of their involvement?
Sigma Software took our platform from wireframe to reality, providing interface design and coding. We're constantly making new developments and maintaining the platform, so Sigma Software remains a key resource in our world. We also have internal product managers, but Sigma Software provides most of the coding.
Sigma Software assigned 8–12 developers to our project. As we added new requirements and expanded the budget for executing on those requirements, the team size grew. Our resources include C++ and JavaScript developers, designers, QA specialists, and database managers. We have a one-to-one collaboration, with a key product manager on our side interfacing with Sigma Software's liaison. Their manager has been integral to our product's success. We do interface with Sigma Software's resources directly from time to time.
How did you come to work with Sigma Software?
I used to be engaged with a company that used Sigma Software's services. We also looked out to the market for partners with end-to-end capabilities for making our platform come to life. We looked in places like India, but also locally, in the US and UK. We also considered hiring in-house resources but came to the conclusion that Sigma Software would be the best choice for creating a market-ready platform in under 6 months.
How much have you invested with Sigma Software?
The cost of Sigma Software's work has been above one million dollars.
What is the status of this engagement?
We started working with Sigma Software in early 2013.
RESULTS & FEEDBACK
Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?
The platform built by Sigma Software became live and revenue-generating within 6 months. There was a lot of feedback in that short period of time, with tweaks, upgrades, and changes to the development schedule. Sigma Software was accommodating and flexible in doing this.
They worked with us in interpreting what we were trying to get done. Our main expertise was around the marketing for a software-as-a-service platform. This kind of interpretation can't happen in a vacuum, but rather through the organic collaboration between coders, designers, and technologists acting as business visionaries.
How did Sigma Software perform from a project management standpoint?
Working within two different time zones has given us time to think and develop requirements, with Sigma Software resuming work while we were sleeping.
We used Skype for live chats, which occurred on a regular basis: daily during the early stages and weekly at the moment. We also used certain software for tech development and timeline tracking on Sigma Software's side, as well as phone and email.
What did you find most impressive about Sigma Software?
One of the reasons for outsourcing a particular component of a business is the gained efficiency, as well as access to the know-how and resources available in certain parts of the world. There are barriers in terms of time zones, cultures, and languages, but Sigma Software embraced our way of communicating. Although their native language isn’t English, they were far better than others in terms of understanding what we were trying to do, regurgitating it back to us, and executing it. I found this aspect to be unique, compared to other outsourcing shops.
Are there any areas Sigma Software could improve?
I can't think of anything off the top of my head. We consider Sigma Software to be a strategic partner and an integral part of what we're doing at this time. They've grown as a company since our first interactions, adding offices in the US and other locations.
