The question asked, verbatim: best business formation services for startups

Brands named, in the order the engine gave

1. Clerky recommended
   Clerky - This is what I'd recommend first for VC-backed founders.
2. Stripe mentioned
   Stripe Atlas - $500 one-time, incorporates in 1-2 business days, includes the first year of registered agent (then $100/yr).
3. Stripe Atlas mentioned
   Stripe Atlas - $500 one-time, incorporates in 1-2 business days, includes the first year of registered agent (then $100/yr).
4. Cooley mentioned
   An actual startup law firm (Gunderson Dettmer, Cooley, Orrick, Wilson Sonsini) - Worth naming even though it's not a "service." Most will defer fees until you raise, which makes the real cost at formation close to zero, and you get a relationship you'll need at your first priced round anyway.

   Firstbase - $399 one-time including state filing fees, Delaware or Wyoming, LLC or C-corp.
6. EIN mentioned
   What you're buying is the back office: US mail/virtual address, EIN, compliance, bookkeeping, tax filings.
7. Northwest Registered Agent recommended
   Northwest Registered Agent - My pick here.
8. Bizee mentioned
   Bizee (formerly Incfile) - $0 + state fee for formation.
9. LegalZoom mentioned
   LegalZoom - The most complete one-stop shop (every state, every entity type, plus trademarks, licenses, tax services, attorney access).

The answer, as recorded

Here's who I'd actually name, in order - the right pick depends mostly on whether you're raising venture money: ## If you're on the venture track (Delaware C-corp, planning to raise) **1. Clerky** - This is what I'd recommend first for VC-backed founders. It's not the cheapest (~$819 for the Lifetime Package, Delaware-only), but it's built by startup lawyers specifically to produce paperwork that survives diligence. Crucially it keeps going after formation: 83(b) elections, SAFEs, priced rounds, option grants, hiring docs. Most formation services hand you a certificate and walk away; the expensive messes I've seen are almost always in the *post*-formation paperwork. ([comparison](https://www.rho.co/blog/stripe-atlas-vs-clerky), [review](https://www.flowjam.com/blog/clerky-review-2026-complete-guide-pricing-alternatives)) **2. Stripe Atlas** - $500 one-time, incorporates in 1-2 business days, includes the first year of registered agent (then $100/yr). Best value in the category if you want venture-ready Delaware docs fast, and it's the easy default if you're already going to run payments on Stripe. The templates are genuinely founder-friendly (standard 4-year vesting, 83(b) filing help). ([source](https://startupsavant.com/service-reviews/stripe-atlas-vs-clerky)) **3. An actual startup law firm** (Gunderson Dettmer, Cooley, Orrick, Wilson Sonsini) - Worth naming even though it's not a "service." Most will defer fees until you raise, which makes the real cost at formation close to zero, and you get a relationship you'll need at your first priced round anyway. If you have any founder complexity - unequal splits, a co-founder leaving, IP assigned from a previous employer, non-US founders - skip the self-serve tools and do this. ## If you're an international founder **4. Firstbase** - $399 one-time including state filing fees, Delaware or Wyoming, LLC or C-corp. Registered agent is a separate $299/yr from day one, so it's not as cheap as it looks. What you're buying is the back office: US mail/virtual address, EIN, compliance, bookkeeping, tax filings. That bundle is the actual pain point when you don't have a US presence. ([source](https://www.rho.co/blog/stripe-atlas-vs-firstbase)) ## If you're bootstrapping an LLC, not raising **5. Northwest Registered Agent** - My pick here. $39 + state fee, registered agent included the first year, and they have a real privacy policy (they don't sell your data) plus genuinely good phone support. No aggressive upsell funnel, which is rarer than it should be. ([source](https://startupsavant.com/best-incorporation-services-for-startups)) **6. Bizee** (formerly Incfile) - $0 + state fee for formation. Cheapest credible option, and fine if you just need an entity to exist. Expect upsells. ([source](https://www.rho.co/blog/best-incorporation-services)) **7. LegalZoom** - The most complete one-stop shop (every state, every entity type, plus trademarks, licenses, tax services, attorney access). I'd name it last for startups specifically: you pay a premium for breadth you probably don't need, and the docs aren't optimized for venture financing. ([source](https://www.newsweek.com/readerschoice/best-business-formation-service-2026)) One thing worth flagging regardless of which you choose: **file your 83(b) election within 30 days of your stock issuance.** It's a hard deadline with no remedy if you miss it, and it's the single most common and most costly founder error. Clerky and Atlas both walk you through it; the cheaper LLC-focused services generally won't.
