Solid delivery, though timelines needed some pushing

Andre Foster / Head of Engineering | Sep 27, 2026

The final product works well for us, although the process could have been smoother. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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 AI & Machine Learning 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 engaged Colto srl to add an AI chatbot to our support site that answers questions from our help docs. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 6-month engagement.

Honest advice and solid execution

Felix Fischer / CEO | Jun 18, 2026

Colto srl did an excellent job for us. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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.

I would recommend Colto srl to anyone looking for a dependable AI & Machine Learning partner.

Project summary

Colto srl was brought in to build a demand forecasting model on top of our sales data. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 7 months.

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.
Why did you choose this company over other providers you considered?
Their pricing was fair and they were honest about timelines instead of just telling us what we wanted to hear.
How clearly did the company understand your requirements and business goals?
They understood our goals quickly, partly because they had worked with Telecommunications clients before.

Organised and transparent. Their project manager kept the project on track and flagged risks early.
Did the company deliver the project on time and within your expected budget?
Yes, on time and within budget.

Quality work, a little slower than we planned

Wei Jie Lim / Marketing Director | Jun 10, 2026

We got a good result in the end, but the road there had a few bumps. They were upfront about what was realistic within our budget, which helped us prioritise the right features. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

It has made a real difference to how our team works day to day. We had to follow up a few times on smaller bug fixes after launch. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We hired Colto srl to develop a field-staff app with offline mode that syncs back to our main system. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 3-month engagement.

Solid Mobile App Development Work With Clear Communication Throughout

Chris Johnson / Product Manager | Jun 04, 2026

I would rate this engagement highly on almost every front. 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 developers were knowledgeable and made a few suggestions that ended up saving us time and money. They shared working builds regularly, so we could test early and give feedback before things were locked in.

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

Good results, communication improved as the project went on

Naledi Naidoo / Co-Founder | May 11, 2026

Overall the project was a success, though it was not without some challenges. They were upfront about what was realistic within our budget, which helped us prioritise the right features. 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 dealt with the same core team throughout, so we did not have to keep re-explaining things.

The result looks great and performs well, and our internal team found it easy to take over. Estimates on a few features were optimistic and those took longer than planned.

Happy to recommend them.

Professional team that made a complex project feel manageable

Tobias Fischer / Owner | Mar 11, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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.
