Fintech · Case studyP3 is a smart corporate expense management platform: total control over company spending, autonomy for teams and efficient financial management, all in one place, with corporate cards issued by P3. In its early days, Marcelo worked with Fernando Nery, P3's founder and CEO, to design and model the platform, its processes, applications and database, and ran the build of its first version.
P3 has since been through Y Combinator twice and raised a seed round led by Better Tomorrow Ventures.
From the first workshop to hosting and support. These are products we built ourselves.

Most of our clients are law firms and start-ups that would rather not be named. We describe the problem, what we did and what changed, and name a client only when they agree, as P3 did.
In consultancy we analyse, design and cost the solution; you own the plan and can build it with anyone. In idea-to-launch work we build it, launch it, host it and support it ourselves.
Yes. We start with a review of what exists and tell you whether to fix it, extend it or replace it.
A proof of concept (POC) shows the riskiest part of an idea works. A minimum viable product (MVP) is the smallest version real users can use and pay for. We usually build one, then the other.
Tell us about your idea or what's slowing you down. We'll listen, ask the awkward questions, and tell you honestly whether we can help.
