The Review
Feedback summary: 

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.


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.


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.


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.


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.
