Good value and a team that genuinely cares about the result

Heather Fisher / Managing Director | Sep 04, 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. Their project manager kept things organised and was quick to flag anything that might affect the timeline. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

We are already seeing better numbers than before the project. Overall, a team we trust and plan to keep working with.

Project summary

Hillmann & Carr Inc was brought in to build a demand forecasting model on top of our sales data. They worked alongside our in-house team, which mostly handled business requirements and testing. The project took roughly 2 months from kickoff to launch.

I'm the Managing Director at Pioneer Networks, a Telecommunications company based in Tampa, USA. I look after our technology and work closely with outside partners on bigger projects.
What specific problem or business challenge led you to hire this company?
Our existing setup was holding us back. We wanted to build a demand forecasting model on top of our sales data before our busy season.
What services did the company provide for your project?
Mainly AI & Machine Learning. They also helped with the technical planning and a few integrations with our existing tools.

Good work overall, with a few bumps along the way

Nikhil Sharma / Managing Director | Jul 31, 2026

We got a good result in the end, but the road there had a few bumps. They shared working builds regularly, so we could test early and give feedback before things were locked in. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

The Game Development work has already made a noticeable difference — tasks that used to take hours now take minutes. There were some early misunderstandings on requirements that took a few rounds to sort out. Overall, a team we trust and plan to keep working with.

Project summary

We partnered with Hillmann & Carr Inc to develop a casual mobile game from concept to launch. They worked alongside our in-house team, which mostly handled business requirements and testing. Overall it was a 3-month engagement.

Strong Technical Skills and a Very Responsive IT Consulting Team

Joanne Lim / CTO | Jun 10, 2026

Hillmann & Carr Inc did good work for us, and we would use them again. They shared working builds regularly, so we could test early and give feedback before things were locked in. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

Since launch, everything has been stable and our team has adapted to it quickly. A couple of milestones slipped by a week or so, mostly around testing.

Happy to recommend them.
