Rui K Miadaira

Real talk, let me break down Rui K Miadaira, this guy’s a straight-up startup machine, no cap. He’s been crushing it for over a decade, jumping into everything from tech to brick-and-mortar and back again. The dude’s a serial entrepreneur and a legit YC alum from S21, so he’s got that real deal startup cred.

His process started with a solid tech background, he’s got a BS in Computer Science from UNICAMP, one of Brazil’s top schools, and an MBA from Harvard. So, he’s got brains and the hustle. But what really sets him apart is how he’s used that knowledge to build stuff that actually works.

First big thing was Ahazou, his baby, a SaaS platform for local Latin American businesses. The thing crushed it: 6 million downloads, 250K active users each month, and pulling in about $100K MRR. That’s no small feat. It shows he’s got the knack for identifying real pain points in local markets and building tools that scale. He’s not just throwing shit at the wall, he’s solving real problems.

Before that, he founded Carreira Beauty, a professional network for the beauty industry in Brazil, which hit over 300,000 pros. Dude sees gaps in markets and jumps in with both feet. He’s not afraid to get into niche stuff, whether it’s beauty, dental clinics, or spas, and turn them into something bigger. Olimpia Spa, with 6 branches and 100+ staff? That’s a legit day spa chain, so he knows how to run big operations too.

His corporate stint is just as telling. He’s been a Senior Product Manager at Itaú Unibanco, one of Brazil’s biggest banks, and worked at C&A, a giant retail chain. Plus, he was a Senior Consultant at Booz & Company. Basically, he’s got the chops in both startups and big biz, which gives him a super broad view of how to scale things.

What’s crazy is how all this ties together. He’s always been about building community, whether it’s local businesses in Latin America or industry-specific networks. Now he’s co-founder of a stealth startup in São Paulo that we don’t even know the name of yet, but considering his track record, it’s probably something big.

Rui’s story is all about hustle, tech, and solving real problems that matter to everyday people. He’s the kind of guy who’s not just in it for the fame, he genuinely wants to shake up markets, enable local entrepreneurs, and build stuff that lasts. He’s a perfect example of what it means to jump into new things, learn fast, and keep pushing forward.

Long story short? Rui K Miadaira is a legit force in the startup world, blending tech smarts, business savvy, and a deep understanding of local markets. The guy’s got the experience, the network, and the drive to turn ideas into reality, and honestly, I’d keep an eye on whatever he’s cooking up next.
