ThumbStack Technologies Private Limited Delivered a Quality AI & Machine Learning Solution on Time

Pooja Sharma / Founder | Oct 18, 2026

Our experience with ThumbStack Technologies Private Limited was really positive from start to finish. 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.

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

Project summary

We hired ThumbStack Technologies Private Limited to add an AI chatbot to our support site that answers questions from our help docs. They worked alongside our in-house team, which mostly handled business requirements and testing. The project took roughly 2 months from kickoff to launch.

Skilled Software Development Team That Understood Our Business

Ruben Jansen / Managing Director | Aug 19, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

We launched on schedule and have not had any major issues since. Happy to recommend them.

Project summary

Professional Software Development Team, Smooth Delivery From Start to Finish

Emily Ahmed / IT Director | Apr 07, 2026

Our experience with ThumbStack Technologies Private Limited was really positive from start to finish. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. 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.

The Software Development work has already made a noticeable difference — tasks that used to take hours now take minutes.

I would recommend ThumbStack Technologies Private Limited to anyone looking for a dependable Software Development partner.

Project summary

ThumbStack Technologies Private Limited was brought in to develop a scheduling and dispatch tool for our field team. The project was split into milestones, with a working build shared at the end of each one. The engagement ran for about 4 months.
