The story of Katherine B. Nammacher

Facts, let me break it down about Katherine B. Nammacher, this is one of those people who just *crushed* it from the start. She’s a legit mix of tech whiz, public servant, and startup hustler all rolled into one. So, she’s from YC’s S17 batch, which already tells you she’s got that startup DNA, she’s been in the trenches since day one.

Her background? It’s wild. She’s worked at big names like VMware and Microsoft, so she’s got that corporate tech grind under her belt. But what’s really interesting? She jumped into the civic world big time. She did a fellowship with Code for America, which lit her fire for making tech work for the people. That led to RideAlong, her own YC-backed startup. She co-founded that with Meredith Hitchcock, and these guys built software to help police and first responders de-escalate 911 calls with vulnerable folks. Think about that, saving lives, reducing violence, and actually making a real difference. RideAlong went from a prototype to getting acquired, and they raised over half a million in funding and did $250K+ in sales.

And it’s more than just the startup hustle. Katherine’s impact? Massive. She helped cut down high-user 911 calls by 35% for Seattle PD. That’s real-world change. Her work’s been recognized at SXSW with a government tech award, and she’s jumped into programs like San Francisco’s Start-Up Residency, basically a badge of being a legit innovator.

Talk to her

Before all that, she was at the White House with the US Digital Service, tackling tough issues like asylum processing, federal hiring, and unemployment fraud. That’s some high-stakes stuff, right? Shows she’s all about using tech to fix big, real problems, not just chasing shiny gadgets.

She’s also been a teacher at Georgetown, dropping knowledge on data-informed policy, which proves she’s about building stuff that actually works in the real world, not just theory. And her background in printmaking and curatorial studies from MICA? Yeah, she’s got that creative side too, probably how she thinks outside the box.

Long story short? Katherine’s process is all about that drive to use tech for good. From big corporate gigs to government and her own startup, she’s constantly pushing to solve real problems, especially in public safety and government. She’s not just about the next app; she’s about having an effect, changing the game, and proving that startups can be the real deal even outside Silicon Valley.

If you ask me, she’s the kind of person who’s here to shake things up, and her story just keeps getting better. No Cap.
