## The answer, as recorded

Asked on 2026-09-25 through Claude (Anthropic) with web search (model claude-opus-5).

> The right answer forks hard on one question: are you raising venture capital, or building a business you'll own yourself? Those lead to completely different providers.

> **1. Clerky** - What I'd recommend first for anything fundraising-bound. It's purpose-built for Delaware C-corps and startup lawyers actually respect the paperwork it generates: founder stock purchase agreements with vesting, 83(b) elections, option grants, board consents, SAFEs and convertible notes. Roughly $799 for the incorporation bundle. The reason it matters isn't incorporation itself - it's that the cap table and equity docs are clean two years later when a VC's counsel does diligence. Most cleanup bills I've seen trace back to sloppy founder equity docs, not the certificate of incorporation.

> **2. Stripe Atlas** - $500 for a Delaware C-corp or LLC, and the best choice if you want to be operational fast with minimal thinking. Includes registered agent and first-year franchise tax handling, 83(b) filing, and a pile of partner credits (AWS, Stripe fee waivers, etc.) that often exceed the fee. Tradeoff: it's a formation event, not a relations

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
