Strong Technical Skills and a Very Responsive AI & Machine Learning Team

Sophie Doyle / Founder & CEO | Oct 13, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They shared working builds regularly, so we could test early and give feedback before things were locked in. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

It has made a real difference to how our team works day to day. Overall, a team we trust and plan to keep working with.

Project summary

Our company worked with Thelios LLC to build a demand forecasting model on top of our sales data. The work covered requirements, design, development, testing and launch support. The engagement ran for about 4 months.

Great team to work with — professional, responsive and reliable

Derek Brooks / Co-Founder | Sep 07, 2026

The project went well overall. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. 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. We had to follow up a few times on smaller bug fixes after launch. Happy to recommend them.

Project summary

Thelios LLC was brought in to automate document data extraction that our team was doing by hand. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 6 months.

Quality work, a little slower than we planned

Emily Harding / Senior Product Manager | Aug 21, 2026

Overall the project was a success, though it was not without some challenges. 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. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

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

Our company worked with Thelios LLC to redesign and rebuild our company website on a modern stack. The project was split into milestones, with a working build shared at the end of each one. The engagement ran for about 4 months.

Delivered on time and stayed involved after launch

Derek Fisher / Co-Founder & CTO | Aug 11, 2026

We launched on schedule and have not had any major issues since.

Skilled Web Development Team That Understood Our Business

Ryan Carter / Owner | May 09, 2026

Our experience with Thelios LLC was really positive from start to finish. 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. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

Since launch, everything has been stable and our team has adapted to it quickly.

Overall, a team we trust and plan to keep working with.
