YC–a16z singles mixer

1.A singles mixer for YC and a16z Speedrun founders. No VCs allowed unless they're very cool. Proposed as a bit, then inevitable: the obvious event for a city where everyone is single until Series B.

They met at the YC–a16z singles mixer. He was raising; so was she. It's a party round now.

It started as a bit on X: if founders are single until Series B, then the market will, eventually, provide liquidity - and what is a singles mixer between YC and a16z Speedrun founders if not a matching marketplace where both sides have already been through due diligence? The bit was Mehul Agarwal's, and the rules were strict: founders only, single only (partners will be DMed), under 30, and no VCs or scouts allowed unless very cool.

The joke lands because SF social life already runs on deal-flow mechanics: demo days double as date nights, coffee chats have term sheets, and every relationship is quietly diligenced. The mixer merely removes the plausible deniability.

The field work has since produced an invite: a "YC x A16z Speedrun Singles Mixer" flyer promising a curated evening of speedy connections for founders, builders, and VCs, complete with laurel wreaths and a sprinting hoplite. Whether the event is real, a bit, or (most likely) both simultaneously is exactly the point. Adjacent phenomena: Corgi girls, ABG CMO.

We hosted SF's only co-ed mixer with more women than men. 45 women, 35 men, and 4 relationships I personally know came out of it. And I'm the guy who went viral for staying "single until series B." Here's the storytime: One random Sunday I tweeted that there should be a singles mixer for YC and a16z speedrun founders. The shitpost hit top news on X. Consensus: "no women will sign up." Instead, dozens of women DMed me: "please make it happen, just keep the ratio right." @dianeemccormack from Fondo offered to run it. @peggy_wang from SparkChat & @parthma said they're single and in. While we planned, I went viral again with my bro @contextconor for joking I'd stay "single until series B." @gregisenberg called it the single worst trend to come out of silicon valley. People called me "everything wrong with SF," said incels were killing the city's dating culture (fun fact: it doesn't exist). So now I was the "single until series B" guy throwing SF's biggest singles mixer. The irony was not lost on me. But a million views, thousands of DMs, and hundreds on the waitlist were counting on me. @pulley signed on to sponsor. So I leaned in. I asked @peggy_wang to be the face of it, dunking on the techbros: sign up so you don't end up like me, single until series B. I was guiding people to a treasure I couldn't possess. And it worked. Best event I've ever hosted. Curated people from every walk of life, not just YC founders, actually hit it off. The girls' group chat is still popping lol. Moral: you can have your cake and eat it too. It's just harder. You can stay "single until series B" and still help everyone else find their person. As @gregisenberg put it in his tweet calling us out: you can have it all. (all love, I like his work) This is independent of my startup @KoyalAI, which helps people make films with AI. Yes, also controversial. I can't help it.

I want to host a singles mixer for @ycombinator & a16z @speedrun founders. SIGN UP BELOW to show interest. You need to be YC or @a16z, need to be SINGLE (we will DM your partner) and below 30. No VCs or scouts allowed unless you’re very cool. I’ve seen this weird rivalry bw YC & a16z founders since I moved to SF. It’s also a fact that almost all of us are single (sorry married losers) If we want to maintain world peace, it’s important that the future generations grow together. This is not a networking event. It’s only for those who want to: create the future people want.
