Open source, closed weekends?
Proliferate (YC S25) is hiring to building open source Codex
Tiny startup wants coding stars, and the comments are already fighting about the hustle
TLDR: Proliferate, a tiny San Francisco startup, is hiring early engineers to help build an open-source coding tool with big pay and big expectations. Commenters are split between admiration for the ambition and jokes that all the wellness perks are just frosting on an extremely intense work culture.
A brand-new San Francisco startup called Proliferate is trying to hire some of its very first engineers, and on paper it’s selling a pretty glossy dream: big pay, equity, free meals, wellness perks, and a chance to help build an open-source coding assistant. The founder, Pablo, is pitching intensity, speed, and "do the best work of your career" energy from an in-person office near Salesforce Park. Translation for non-tech readers: small team, big ambition, very little chill.
And yes, the community absolutely had thoughts. The loudest reaction was a split between “this is how great companies get built” and “this sounds like a burnout starter pack with snacks.” Some commenters loved the raw ambition and said being one of the first hires at a tiny company can be career rocket fuel. Others immediately zoomed in on the vibe: ultra-high standards, in-person only, work trial in San Francisco, and health perks like a company-paid Whoop fitness band. That combo sparked plenty of jokes about startups offering wellness budgets while quietly advertising maximum stress as a lifestyle.
The funniest reactions practically wrote themselves. People joked that the real product is “sleep deprivation with dental,” while others mocked the startup ritual of saying work-life balance matters right after describing an all-consuming mission. Still, fans argued this is exactly the kind of intense early-stage gamble that can become huge. In other words: inspiring opportunity or glamorized grindfest? The comments could not decide, and that’s why everyone kept reading.
