Great team to work with — professional, responsive and reliable

Carlos Coleman / Director of IT | Aug 13, 2026

TESO l.l.c. 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. 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 launched on schedule and have not had any major issues since. Estimates on a few features were optimistic and those took longer than planned. We would definitely work with them again.

Project summary

We partnered with TESO l.l.c. to improve our release process, which involved a lot of manual steps. They also took care of integrations with a couple of third-party tools we already used. We worked together for around 8 months.

Professional AI & Machine Learning Team, Smooth Delivery From Start to Finish

Pooja Agarwal / CEO | Jul 23, 2026

We were very happy with how this project went. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

The result looks great and performs well, and our internal team found it easy to take over. If you need a team that communicates well and delivers, they are a good choice.

Project summary

Our company worked with TESO l.l.c. 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 engagement ran for about 8 months.

Professional team that made a complex project feel manageable

Sam Holmes / Owner | Jul 04, 2026

We were very happy with how this project went. We dealt with the same core team throughout, so we did not have to keep re-explaining things. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

We launched on schedule and have not had any major issues since. I would recommend TESO l.l.c. to anyone looking for a dependable Mobile App Development partner.

Project summary

We engaged TESO l.l.c. to rebuild our existing mobile app, which had poor reviews and frequent crashes. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 6 months.

Capable E-commerce Development team — happy with the end result

Kelly Coleman / Co-Founder | Jun 22, 2026

The final product works well for us, although the process could have been smoother. 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.

It has made a real difference to how our team works day to day. Their team changed one developer midway, which slowed things down for a couple of weeks. Overall, a team we trust and plan to keep working with.

Project summary

We hired TESO l.l.c. to build a Shopify store with custom features for our product range. They also took care of integrations with a couple of third-party tools we already used. We worked together for around 9 months.

Would happily work with them again

Rahul Verma / VP of Engineering | May 04, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Their project manager kept things organised and was quick to flag anything that might affect the timeline. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

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

Happy to recommend them.

Project summary

We engaged TESO l.l.c. to containerize our application and move it to Kubernetes. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 4 months from kickoff to launch.

Solid delivery, though timelines needed some pushing

Siddharth Menon / CTO | Apr 09, 2026

We got a good result in the end, but the road there had a few bumps. 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 team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

Since launch, everything has been stable and our team has adapted to it quickly. Documentation at handover was a bit thin and we had to ask for more detail.

We are already discussing the next phase with them.
