Machine learning models that turned raw data into genuine business decisions

Rafael Almeida / CTO - Horizonte Digital Ltda
Verified
Apr 03, 2022

Project summary: Our existing platform had grown organically over several years and the accumulated technical debt was beginning to affect both performance and our ability to ship new features.

We ran a structured RFP with seven vendors. Three made it to the technical evaluation stage. This team won on the strength of their technical proposal, their domain knowledge, and frankly on the quality of the questions they asked us during the process. A vendor who asks good questions in the sales phase tends to ask good questions during delivery too. That hypothesis proved correct. The project is now live, performing above the KPIs we agreed, and our stakeholders are genuinely impressed.

PROS

Architectural decisions that will serve us for years rather than just solving the immediate problem, knowledge transfer that left our team genuinely capable, no scope creep at all

CONS

Time zone difference required some adjustment to our internal communication habits but the team managed the overlap window efficiently and it never affected momentum

Questions & Answers

Please describe your company, your role, and the industry you operate in.
I lead technology at Horizonte Digital Ltda, a mid-sized organisation in the Mining & Metals sector headquartered in São Paulo, Brazil. My remit as CTO covers everything from infrastructure to product development. We had reached a point where our internal engineering capacity was not sufficient to execute our roadmap without an experienced external partner.
What specific problem or business challenge led you to hire this company?
Our existing AI & Machine Learning capability had accumulated years of technical debt that was slowing every new feature to a crawl. Incident frequency was rising, developer confidence was falling, and we knew a rebuild was overdue. We needed a partner with the depth to do it properly rather than apply another layer of patches.
What services did the company provide for your project?
End-to-end AI & Machine Learning delivery with a particular emphasis on the integration layer that connected the new build to our existing Mining & Metals infrastructure. They also provided UI/UX input that was not in the original scope but which they offered proactively because they could see it would affect adoption. That kind of initiative was characteristic of how they approached the whole engagement.
Why did you choose this company over other providers you considered?
We evaluated four vendors in total. Two were eliminated after the technical assessment stage because their proposed architectures showed a surface-level understanding of what we needed. This team's proposal demonstrated genuine depth in AI & Machine Learning and specific knowledge of the Mining & Metals sector that the others could not match. The reference calls confirmed a consistent pattern of delivery.
How clearly did the company understand your requirements and business goals?
The requirements understanding was solid from early on, aided by the fact that they had prior experience in the Mining & Metals sector and did not need us to explain domain context that a less experienced team would have required. That background knowledge shortened the discovery phase meaningfully and reduced the volume of clarification questions during sprints.
How was your overall experience with their communication and project management?
Professional and efficient. We used a shared project management tool that gave our stakeholders visibility without requiring them to attend every meeting. The project manager had a clear escalation path and used it appropriately. The only time I needed to intervene directly was when I chose to, not because something had been missed.
Did the company deliver the project on time and within your expected budget?
The project landed on the agreed delivery date and within the approved budget. We did add scope during the engagement — two features that became apparent as essential during user testing — and those were quoted, approved, and delivered without affecting the original scope timeline. That kind of clean change management is not something you can take for granted.
What tangible results or business impact have you seen since the project was completed?
The most direct measure is that the problem we hired them to solve no longer exists. Beyond that, the new AI & Machine Learning platform has reduced our operational overhead measurably, our team spends less time managing incidents and more time on product development, and we have been able to onboard two new enterprise clients who had previously cited our technical limitations as a barrier.
What did you like most about working with this company?
The post-launch behaviour. Some agencies disappear the moment the final invoice is paid. This team maintained the same level of responsiveness during the hypercare period as during development, handed over thorough documentation without being asked twice, and checked in proactively a month after go-live to review performance metrics with us. That last part was entirely unprompted.
Would you recommend this company to others, and would you work with them again?
Unreservedly. We are in active conversation about the next phase of work and I expect this to become a multi-year partnership. For any organisation in the Mining & Metals space looking for a AI & Machine Learning partner who combines technical rigour with genuine commercial awareness, I would put this team at the top of the shortlist.
