The answer, as recorded

For a venture-track startup (Delaware C-corp, planning to raise), here's who I'd actually name, in order: **1. Clerky - $819 lifetime package.** My default recommendation if you intend to raise money. It was built by startup lawyers, and its documents are the ones investors and law firms already expect to see, so nothing gets re-papered during diligence. The lifetime package covers formation *plus* the post-incorporation stack you'll immediately need - bylaws, stock purchase agreements with vesting, 83(b) guidance, board consents - and then unlimited ongoing docs: SAFEs, option grants, offer letters, advisor agreements. The price is the whole point: it's cheaper than one hour of a startup attorney's time and it prevents the classic expensive cleanup (founder stock never actually issued, missed 83(b), no IP assignment). **2. Stripe Atlas - $500 one-time, 1-2 business days.** The fastest and cheapest credible path to a Delaware C-corp, and the best pick if you have non-US founders - its workflow handles international founders well, and it bundles EIN support, a free year of registered agent, and partner credits. Trade-off: it's a one-time formation product with no ongoing legal document tooling, so you'll pay a lawyer or sign up for Clerky later anyway. Great if you're pre-idea-validation and want to be incorporated this week. **3. Firstbase - $399 including state fees.** Formation in Delaware or Wyoming as the on-ramp to a subscription services stack: registered agent, virtual mailing address, compliance filings, bookkeeping, tax. Pick this if you're a solo or non-US founder who wants someone handling the boring recurring obligations, not if you're optimizing for investor-ready paperwork. **4. Northwest Registered Agent - best registered agent, roughly $125/yr.** Whoever forms your company, you need a registered agent in Delaware plus every state you have employees in. Northwest is who I'd use: genuinely good humans on the phone, they don't upsell, and they don't sell your data. I'd often use them for registered agent even when forming through Clerky or Atlas. **5. LegalZoom or Bizee - for a non-venture small business.** If you're forming an LLC for a consultancy, agency, or local business and have no intention of raising institutional capital, skip the startup-specific tools. LegalZoom is the most complete start-to-scale option (all 50 states, annual reports, trademarks, tax services); Bizee is cheaper for the same core filings. Clerky would be the wrong tool and overpriced for you. **6. A startup law firm - Cooley, Gunderson, Orrick, Fenwick.** Worth knowing: if you've already got real investor interest or an unusual cap table (more than ~3 founders, non-US entity, university IP, an existing LLC to convert), these firms will often form you with fees deferred until your priced round. That's frequently the right answer over any software, and the firms themselves generally use Clerky-style docs. Two things worth flagging regardless of what you choose: file your 83(b) election within 30 days of your stock purchase - it's unforgiving and the single most common expensive mistake - and get signed IP assignment agreements from every founder and contractor on day one, because that's the thing diligence actually blocks on.
