Reliable IT Consulting Partner That Delivered What They Promised

Khalid Fernandes / Founder & CEO | Aug 23, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

It has made a real difference to how our team works day to day. If you need a team that communicates well and delivers, they are a good choice.

Project summary

Sullivan Higdon & Sink was brought in to assess our architecture before a major product rebuild. They worked alongside our in-house team, which mostly handled business requirements and testing. The project took roughly 7 months from kickoff to launch.

Skilled Software Development Team That Understood Our Business

Emma Chen / Product Manager | Jul 30, 2026

Overall we had a good experience working with Sullivan Higdon & Sink. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

The result looks great and performs well, and our internal team found it easy to take over. A couple of milestones slipped by a week or so, mostly around testing.

Happy to recommend them.

Professional team that made a complex project feel manageable

Naledi Botha / IT Director | May 15, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They shared working builds regularly, so we could test early and give feedback before things were locked in.

We are already seeing better numbers than before the project. I would recommend Sullivan Higdon & Sink to anyone looking for a dependable DevOps Services partner.
