Skilled AI & Machine Learning Team That Understood Our Business

Ananya Nair / Founder | Aug 08, 2026

Our experience with TESO was really positive from start to finish. They were upfront about what was realistic within our budget, which helped us prioritise the right features. 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.

Feedback from our customers has been very positive so far. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We engaged TESO 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 7 months from kickoff to launch.

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Greenfield Estates is a Real Estate business in Jaipur, India. As Founder, I was responsible for this project on our side and the main contact for TESO.
What specific problem or business challenge led you to hire this company?
We had tried to do this internally and it stalled. We needed specialists to add an AI chatbot to our support site that answers questions from our help docs.
What services did the company provide for your project?
End-to-end AI & Machine Learning — from requirements and design through to deployment and a support period afterwards.
Why did you choose this company over other providers you considered?
They had relevant experience in Real Estate and their proposal was the clearest of the ones we received.
How clearly did the company understand your requirements and business goals?
Well. There were a couple of points we had to clarify early on, but after that they were spot on.
How was your overall experience with their communication and project management?
Communication was good overall and improved further once we settled into a routine.
Did the company deliver the project on time and within your expected budget?
Mostly. One milestone slipped by about a week, but the final delivery was on schedule and the budget held.
What tangible results or business impact have you seen since the project was completed?
We can now handle more volume without adding staff, which was the main goal.
What did you like most about working with this company?
That they were proactive — they suggested improvements instead of just doing what was asked.
Would you recommend this company to others, and would you work with them again?
Yes, I've already recommended them to a couple of people I know.

Exceeded our expectations on quality and communication

Dan Coleman / Founder & CEO | Jul 27, 2026

We were very happy with how this project went. Their project manager kept things organised and was quick to flag anything that might affect the timeline. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

The Software Development work has already made a noticeable difference — tasks that used to take hours now take minutes. We would definitely work with them again.

Project summary

We partnered with TESO to rebuild an internal order management system that had outgrown its original design. Scope included discovery workshops, development in two-week sprints and a short support period after launch. Overall it was a 8-month engagement.

Honest advice and solid execution

Siddharth Menon / Operations Manager | Jul 04, 2026

Our experience with TESO 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. 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.

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

Happy to recommend them.

Project summary
