## The answer, as recorded

Asked on 2026-10-04 through Claude (Anthropic) with web search (model claude-opus-5).

> Short version: the right pick depends almost entirely on whether you're building a venture-track company or a small business, because those are two different products.
> 
> ## If you're raising (or plan to raise) outside money - Delaware C-corp
> 
> **1. Clerky** - This is what I'd name first for anyone whose cap table will be looked at by a VC's lawyer. It generates documents in exactly the form startup counsel expects, which means no cleanup bill at your seed round. ~$427 for company formation, $299 for post-incorporation, or $819 for the lifetime package that covers SAFEs, hiring docs, and equity grants forever. The expensive option up front and the cheapest one in diligence.
> 
> **2. Stripe Atlas** - Flat $500, one number, done in 1-2 business days. Includes Delaware filing, EIN, founder equity docs, 83(b) election filing, first-year registered agent, plus $2,500 in Stripe credits. The standout case is a **non-US founder** who needs a US entity and US payment rails without hiring a lawyer. Registered agent renews around $100/year.
> 
> **3. Firstbase** - $399 including state fees, and it leans "platform" rather than "filing": EIN, registered agent, bylaws, and a real business address via virt
