Of about 500 developers approved for the Cerebral Valley "Built with Opus 4.7" hackathon, only 2 are Brazilian.
Core trick
A scout agent crawls 1,240 curated sources weekly, and a strategist agent ranks matches and cites the user's own GitHub and CV evidence.
Description
Of about 500 developers approved for the Cerebral Valley "Built with Opus 4.7" hackathon, only 2 are Brazilian. The same ratio shows up across fellowships, grants, and accelerators. Brazil has over a million developers. The talent isn't missing. It's unmapped.
Radar is a career plan, not a job board. Three Claude Opus 4.7 agents working together. Anamnesis reads you, your GitHub, your CV, your trajectory, and writes a profile honest enough to use in an application. Scout is one shared agent that runs on its own every week, crawls 1,240+ curated sources (FAPESP, Emergent Ventures, Chevening, MEXT, YC, Fundação Estudar, GSoC, MATS), and adds new ones it discovers along the way. Strategist matches the two: it ranks the opportunities for you specifically, writes a why-you paragraph that cites things you actually did, and lays out a 90-day plan around the cards it picked.
I opened the waitlist this week. Fifty Brazilian developers signed up in five days. I sat down with five of them. An undergrad with published research and mentors who couldn't name a single fellowship he was a strong fit for. A senior mid-career engineer looking for what's next. A junior dev who got her first job through a referral and had never heard any of this existed. Different stages, same gap: not "I don't know what exists", but "I don't know what I'd be a fit for".
Brazil doesn't have a brain drain. It has an information drain. Radar finds the opportunity, and finds the person.
