## The answer, as recorded

Asked on 2026-09-27 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's who I'd actually point you to, and it depends a lot on whether you mean "venture-backed startup" or "small business."
> 
> ## If you're raising (or plan to raise) VC money - Delaware C-corp
> 
> **1. Clerky** - My default recommendation for anyone who intends to fundraise. It's built by startup lawyers specifically for the venture path: incorporation, founder stock issuance with vesting, 83(b) elections, bylaws, board consents, IP assignments, and later on SAFEs and priced rounds. Roughly $799 for incorporation + option pool versus $5k-$15k at a law firm. The real value is that your paperwork survives diligence two years later without a cleanup bill. Caveat worth knowing: Clerky generates the documents and walks you through filing, it isn't a full white-glove filer.
> 
> **2. Stripe Atlas** - Best if you want speed and a working company fast. $500 one-time covers Delaware incorporation (including state fees, next-day processing), EIN, founder equity issuance, and 83(b) filing. Docs were built with Cooley. You also get the $500 credited back if you fund a Stripe Treasury account with $5k, plus ~$2,500 in Stripe credits. Also the best option if you're a non-US founder, since it handles EI
