Co-founded VivaReal, later merged and sold to OLX Brasil, then co-founded Latitud, the community and platform for Latin American founders that also publishes some of the region’s most cited angel-investor rankings.

Track record
VivaReal
Co-founded the Brazilian real-estate listings platform VivaReal, which later merged into Grupo ZAP and was ultimately sold to OLX Brasil — one of the more prominent US-founder-in-Brazil exit stories of its generation.
Latitud
Co-founded Latitud with Gina Gotthilf, building a community and platform for Latin American founders that runs programs, publishes research, and — notably for this site’s purposes — compiles recurring, founder-voted rankings of the region’s most active angel investors.
"Viva the Entrepreneur"
Wrote a book of the same title chronicling the lessons from building VivaReal, which has become a reference point for founders operating in Latin America specifically, as distinct from generic startup advice written for the US market.
How he invests
Requarth’s angel activity draws directly on his own experience as a foreign founder building and exiting a company in Brazil, and his public commentary (through Latitud and his own writing) often focuses on the specific challenges of building in Latin America versus the US.
As with most active angels, a complete, itemized personal portfolio is not comprehensively public — his influence on the ecosystem is felt as much through Latitud’s community and content as through any individually disclosed investment.
What an angel can take from this
Founder-turned-investor communities are the region's real infrastructure
Organised founder communities have done more to standardise how Latin American startups raise money — what a normal SAFE looks like, what terms are acceptable, which lawyers understand cross-border structures — than any single fund. For a new angel, joining one is the fastest way to see what a market-standard deal actually looks like.
Ask what the community is selling
Communities and platforms in this space monetise through membership, events, sponsorship, or carried interest on deals they syndicate. None of those is disqualifying, and all of them shape which deals you get shown. Ask directly, and treat the answer as part of the diligence rather than as a rude question.
