Company formation products are cheap and attractive, but serious startups should choose a law firm that defers fees until funding is raised. Otherwise, you'll accrue billable hours as lawyers fix issues to align with their workflows during fundraising.

We need more VC in AI, these quadruple layer SPVs are skimming too much.

I miss June 2025 when unlimited AI was cheap. Just like $2 Ubers in 2015.

Hours after I signed up for @tryramp I started getting phone calls from American Express. Who's leaking leads at Ramp?

This resonates. It's very difficult to automate human centric SOPs at scale. Automation has to be at the forefront of the system design process.

Don’t you need to background check employees for SOC 2?

PSA: there’s a guy named Soham Parekh (in India) who works at 3-4 startups at the same time. He’s been preying on YC companies and more. Beware. I fired this guy in his first week and told him to stop lying / scamming people. He hasn’t stopped a year later. No more excuses.

What's the furthest a startup has gotten with just a Stripe Atlas setup before a lawyer had to fix everything like board consents, stock, IP assignment, etc?

My home insurance in California renewed at only a 20% increase, which is honestly better than I was expecting.

Bay Area parents love to brag that their toddlers only get one hour of screen time only on weekend days. What's their secret!? The weekend nanny doesn’t start until 8 a.m.
