The answer, as recorded
Here's who I'd actually name, and the order depends a little on whether you mean "VC-track startup" (Delaware C-corp, planning to raise) or "small business" (LLC). I'll lead with the first reading, since that's what "startup" usually signals. ## If you're building a venture-backed startup (Delaware C-corp) **1. Clerky** - my default recommendation. It's built specifically for startups that will raise money, and it doesn't just incorporate you: it handles the paperwork that actually trips founders up later - founder stock purchase agreements, 83(b) elections, IP assignments, stock plans, SAFEs, and priced rounds. VC lawyers know and trust its documents, so you don't pay someone $5k to clean up a mess during diligence. ~$819 one-time for the Lifetime Package. ([Rho comparison](https://www.rho.co/blog/stripe-atlas-vs-clerky), [Startup Savant](https://startupsavant.com/service-reviews/stripe-atlas-vs-clerky)) **2. Stripe Atlas** - the best value if you want speed and low cost. ~$500, incorporates in 1-2 business days, gives you Delaware C-corp or LLC, EIN, first-year registered agent, and a stock plan, plus a pile of partner credits. Caveat: ~$100/year after year one, and you'll be sourcing your financing documents elsewhere. Great if you're pre-raise and cost-sensitive. ([Stripe Atlas guide](https://guptadeepak.com/startup-offers/guides/stripe-atlas)) **3. Carta** - not really a formation service, so don't pick it for that, but it's where you'll end up for the cap table, 409A valuations, and equity administration once you have employees and options. Worth knowing now so you don't double-pay later. **4. A startup lawyer (Gunderson, Cooley, Orrick, Fenwick, or a solo)** - worth mentioning because many of these firms will defer fees until your first priced round. If you have any non-standard structure (multiple founders with uneven vesting, a foreign parent, existing IP from a previous employer, a spinout), skip the self-serve tools and talk to a human. The tools assume a clean, standard cap table. ## If you mean a small business / LLC **5. Northwest Registered Agent** - the one I'd pick. Genuinely good human support, strong privacy practices (they use their address, not yours, on public filings), and they don't bury you in upsells the way the bigger brands do. ([Startup Savant](https://startupsavant.com/best-incorporation-services-for-startups)) **6. LegalZoom** - the most complete "everything in one place" option: formation in every state, registered agent, annual reports, trademarks, licenses, tax services. More expensive and more aggressive on add-ons, but convenient if you want one vendor. ([same source](https://startupsavant.com/best-incorporation-services-for-startups)) **7. Bizee** (formerly Incfile) - cheapest credible option for a basic LLC; free formation plus state fees, first year of registered agent included. Watch the renewal pricing. **8. Rho** - bundles incorporation, attorney review, and business banking together. Reasonable if you want banking solved in the same motion, though I'd rather pick the best-in-class tool for each. ([Rho](https://www.rho.co/blog/best-incorporation-services)) **One thing worth more than the vendor choice:** file your 83(b) election within 30 days of your founder stock purchase. Missing it is the single most expensive, least reversible mistake in this whole process, and it's the main reason I'd pay the Clerky premium over Atlas if you're raising - Clerky actively walks you through it. **Sources:** - [8 Best Online Incorporation Services for Startups in 2026 - Startup Savant](https://startupsavant.com/best-incorporation-services-for-startups) - [Stripe Atlas vs. Clerky: 2026 Incorporation Guide - Rho](https://www.rho.co/blog/stripe-atlas-vs-clerky) - [Stripe Atlas vs. Clerky - Startup Savant](https://startupsavant.com/service-reviews/stripe-atlas-vs-clerky) - [The 10 Best Incorporation Services for Startups in 2026 - Rho](https://www.rho.co/blog/best-incorporation-services) - [Stripe Atlas: cost, perks, and alternatives](https://guptadeepak.com/startup-offers/guides/stripe-atlas)
