Brands named, in the order the engine gave

1. Stripe recommended
   Stripe Atlas - my default recommendation.
2. Stripe Atlas recommended
   Stripe Atlas - my default recommendation.
3. Clerky mentioned
   Clerky - the pick if you're going to be doing real legal paperwork repeatedly: SAFEs, priced rounds, option grants, advisor agreements.
4. Firstbase mentioned
   I'd skip Firstbase and LegalZoom for this use case - Firstbase has a rough enough support/delay reputation that I wouldn't put my incorporation on it, and LegalZoom's documents aren't built for venture financing.
5. LegalZoom mentioned
   I'd skip Firstbase and LegalZoom for this use case - Firstbase has a rough enough support/delay reputation that I wouldn't put my incorporation on it, and LegalZoom's documents aren't built for venture financing.
6. Northwest Registered Agent mentioned
   Northwest Registered Agent - $39 + state fees, free first year of registered agent, then a flat $125/yr.
7. Bizee mentioned
   Bizee (formerly IncFile) - cheapest legitimate path.
8. ZenBusiness mentioned
   ZenBusiness - nicest dashboard and compliance reminders, $0 starter tier, but note the free tier excludes the operating agreement and EIN, and registered agent renews at $199/yr with no discount - the most expensive of the three over time.

   LegalZoom - Rho (https://www.rho.co/blog/stripe-atlas-vs-clerky)

The answer, as recorded

The right answer depends on which kind of "startup" you are, so here's my ranked list with that split baked in. ## If you're on the VC track (Delaware C-corp, plan to raise) **1. Stripe Atlas** - my default recommendation. $500 flat, one-time, and it does the whole thing end to end: Delaware C-corp filing in 1-2 business days, EIN via automatic SS-4, founder stock purchase agreements, and it now files your **83(b) election with the IRS for you** - which is the single most expensive thing founders screw up (miss the 30-day window and you can owe tax on your own equity's appreciation). First year of registered agent is included, ~$100/yr after. You don't have to use Stripe payments to use it, and it's open to non-US founders. ([pricing detail](https://sparklaun.ch/compare/stripe-atlas), [review](https://startupowl.com/reviews/stripe-atlas)) **2. Clerky** - the pick if you're going to be doing real legal paperwork repeatedly: SAFEs, priced rounds, option grants, advisor agreements. The documents are what actual startup law firms use, at ~$799 instead of $5k-$15k. Important caveat: Clerky's incorporation product handles the docs, and it's the post-formation document machine that's the real value - pair it with Atlas or use it standalone if you're comfortable. Choose it over Atlas if your cap table is going to get complicated fast. ([comparison](https://www.rho.co/blog/stripe-atlas-vs-clerky)) **3. A startup lawyer on a flat fee** - worth naming because it's the honest third option. If you have a non-standard founder split, international co-founders, IP assigned from a previous employer, or you're spinning out of a university, $2k-$5k for a real attorney beats any software. Formation mistakes surface during diligence, when they're 10x more expensive. I'd skip **Firstbase** and **LegalZoom** for this use case - Firstbase has a rough enough support/delay reputation that I wouldn't put my incorporation on it, and LegalZoom's documents aren't built for venture financing. ([Firstbase concerns](https://startupsavant.com/service-reviews/stripe-atlas-alternatives)) ## If you're bootstrapping / forming an LLC **1. Northwest Registered Agent** - $39 + state fees, free first year of registered agent, then a flat $125/yr. The reasons I put it first are non-price: it doesn't sell your data, it has genuinely good humans on the phone, and it has the fewest upsells in the category. ([review](https://registeredagentcost.com/northwest-registered-agent-review/)) **2. Bizee** (formerly IncFile) - cheapest legitimate path. $0 + state fees, includes an operating agreement, free registered agent year one then $149/yr. Lowest 3-year total cost (~$298 vs Northwest's ~$375). Take this one if budget is the binding constraint. ([comparison](https://registeredagentcost.com/northwest-vs-bizee/)) **3. ZenBusiness** - nicest dashboard and compliance reminders, $0 starter tier, but note the free tier excludes the operating agreement and EIN, and registered agent renews at $199/yr with no discount - the most expensive of the three over time. ([details](https://registeredagentcost.com/zenbusiness-vs-bizee/)) ## Two things that matter more than the vendor - **Don't form an LLC if you intend to raise venture money.** VCs generally can't invest in LLCs (pass-through income breaks their LPs' tax situation), so you'll pay to convert later. Delaware C-corp from day one. - **The 83(b) is the real risk.** Whatever you pick, confirm it's filed within 30 days of your stock issuance. Atlas automating this is most of why it's my #1.
