## The answer, as recorded

Asked on 2026-10-14 through Claude (Anthropic) with web search (model claude-opus-5).

> The right answer depends almost entirely on one fork: are you raising venture money (→ Delaware C-corp, clean cap table matters more than price), or building a bootstrapped/small business (→ LLC, price and registered agent matter most)? Here's who I'd actually name, in order.

> ## If you're raising VC money
> 
> **1. Clerky** - My top pick for anything that will take outside investment. It was built by startup lawyers specifically to produce documents that pass investor due diligence: Delaware C-corp, founder stock with vesting, 83(b) elections, IP assignments, and later your safes and priced rounds. It's not the cheapest, but the thing you're buying is *not having to pay a law firm $10k to clean up a broken cap table* later. Used heavily by YC-adjacent companies.
> 
> **2. Stripe Atlas** - $500 one-time, including the Delaware filing fee and next-day expedited processing. Incorporation lands in 1-2 business days; EIN in 1-3 days with a US SSN, but 15-45 days without one. You get the Delaware C-corp, registered agent, standard founder docs, 83(b) filing help, and a Stripe account. Best value in the category if your structure is simple and conventional.
> 
> **3. Firstbase** - Pick this over Atl
