Savannah Tynan

Yo, check this out. Savannah Tynan is the real deal. She’s the CTO and co-founder of Sieve, a YC X25 startup that’s basically changing the game for finance data. Like, she jumped into this space because she saw how messy and error-prone data cleaning is in hedge funds and financial firms. No cap, that shit is a nightmare-manual, slow, full of mistakes. So she decided to build something smarter.

Before all this, Savannah was at Bain in the private equity squad. That’s where she got her hands dirty with real finance data problems. She saw firsthand how much time and effort goes into cleaning and prepping data-stuff that’s super boring but key. And I think that’s what pushed her to do something about it. She’s not just some techie throwing AI at problems; she’s someone who’s been in the trenches, knows what the finance folks struggle with, and decided to fix it.

Then she teamed up with Nicole Lu, who’s got a PhD from MIT and some serious chops from Citadel and McKinsey. Together, they built Sieve to automate the whole data extraction and cleaning process. Their special feature? They combine AI with human review, so the data is almost always spot-on, ready to plug into workflows via API or Excel-whatever the client needs. Basically, they’re eliminating the manual bullshit that’s been dragging down analysts and engineers, letting them focus on higher-value stuff.

What’s crazy is how Savannah’s process shows she’s all about solving real problems. She’s not just chasing the shiny tech; she’s driven by understanding what’s broken and fixing it at the core. That’s why Sieve is such a big deal-because she’s been in the trenches and built something that actually makes a difference. Her background, from Bain to founding a YC startup, screams she’s got the grit, smarts, and vision to crush it.

Bottom line: Savannah Tynan isn’t just another founder. She’s someone who saw a huge pain in finance, jumped into the deep end, and built a tool that’s actually gonna change how data is handled in finance forever. That’s why she’s important-she’s the real deal.
