Professional team that made a complex project feel manageable

Lena Fischer / Co-Founder & CTO | Oct 20, 2026

I would rate this engagement highly on almost every front. 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. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

The result looks great and performs well, and our internal team found it easy to take over. Happy to recommend them.

Project summary

We hired Mandelbrot 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. We worked together for around 8 months.

Mandelbrot Delivered a Quality Mobile App Development Solution on Time

Chris Graham / Managing Director | Oct 09, 2026

Mandelbrot did an excellent job for us. They shared working builds regularly, so we could test early and give feedback before things were locked in. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

Feedback from our customers has been very positive so far. We would definitely work with them again.

Would happily work with them again

Heather Ramirez / Director of Technology | Aug 23, 2026

I would rate this engagement highly on almost every front. Their project manager kept things organised and was quick to flag anything that might affect the timeline. 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. I would recommend Mandelbrot to anyone looking for a dependable AI & Machine Learning partner.

Good value and a team that genuinely cares about the result

Lauren Reed / VP of Engineering | Jul 04, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. 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.

The Mobile App Development work has already made a noticeable difference — tasks that used to take hours now take minutes. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We partnered with Mandelbrot to rebuild our existing mobile app, which had poor reviews and frequent crashes. Their team handled planning, development and QA, with our product owner signing off each milestone. The engagement ran for about 3 months.
