IT Staff Augmentation for Aviation Company
4.0 Aug 14, 2024It's clear that the team takes responsibility and ownership for their deliveries, so they have direct communication with the customers in order to have questions clarified and sorted out. Thus far, we haven't ended up in a situation where we need to redo things due to bad-quality work, so Sigma Software Group's work is very straightforward and on time. Sigma Software Group's commitment, ownership, and willingness to be part of a bigger corporation and adapt to our ways of working has been outstanding. Their team always brings perspective and advice, but it's very easy for them to assimilate our processes and provide our services in a way that our customers don't really see a difference.

Staff Augmentation & Custom Software Dev for GameTech Co.
5.0 Sep 29, 2020They delivered way over our expectations. If it was up to me, I’d only have people from Sigma Software. The level of technicality they have is incredible. They’re very skilled developers and can also come up with architectural and implementation solutions, along with setting everything up themselves. In the one year I’ve been with Sigma Software, they’ve always delivered on time or before. They haven’t been late once.

Get My MatchesWhy Trust Clutch
At Clutch, we believe trust is the foundation of every business relationship. Our mission is to help buyers make confident, data-backed decisions informed by real client experiences.
Every review on Clutch undergoes a rigorous, human-led verification process to make sure it’s valid. Our team of specialists confirms the identity of each reviewer, ensures the project is legitimate, and only publishes reviews that meet our strict criteria.
Verification doesn’t stop at the point of publication. Our Trust & Safety team routinely audits older reviews against our guidelines. When reviews fall short of our standards, we remove them.
We evaluate service providers using a structured methodology that combines:
- In-depth client interviews and ratings
- Comprehensive project details
- Market presence
- Portfolio examples and industry recognition
This data powers tools like the Leaders Matrix, which helps you compare agencies directly. Our research team curates rankings by weighing verified reviews most heavily, so the most trusted and experienced providers rise to the top.
Using this unique combination of verified client feedback and provider-supplied insights, Clutch distills the most important details into clear, digestible summaries so you have everything you need to make confident, informed decisions quickly.
We take fraud seriously. Providers who violate our guidelines may face lower rankings, restricted visibility, or removal from the platform altogether.
Clutch’s commitment to transparency is ongoing. We’re constantly refining our systems to protect the integrity of reviews and support you in finding the right agency.

A Clutch Leaders Matrix provides a broad view of the top-performing companies in a particular service or location. Each company featured in a Leaders Matrix is evaluated based on Focus and Ability to Deliver. The size of each circle indicates that company’s size.
By using verified reviews, focused service details, and real project data, the Leaders Matrix highlights companies that consistently deliver and stand out from the rest. Each company’s position is based on how well they focus on a service area and how consistently they deliver results, helping you make informed, confident decisions. Learn More
