Summary
Automated formation tools like Clerky and Stripe Atlas give you solid standard documents, and founders still end up with expensive legal gaps. The mistakes happen in the decisions the platforms can’t make for you, and the longer they sit, the more they cost to unwind.
What can Clerky and Stripe Atlas handle for you?
Clerky and Stripe Atlas, two of the best-known automated legal formation tools, handle standard incorporation paperwork well, along with many of the routine filings around it.
Stripe Atlas forms a Delaware C corporation or LLC, gets your tax ID, issues founder equity, and files your 83(b) election, using templates built with Cooley. Clerky covers formation, post-incorporation setup, fundraising documents, and hiring paperwork with the startup-standard forms lawyers use.
That said, none of these tools give you legal advice about your own company, and they are very clear about this in their own terms of service. As of September 2026, Atlas's terms say it “is not a law firm” and that its information “is not legal, tax, or accounting advice,” and Clerky's say “we’re not a law firm and we’re not your attorney.”
In short, you're paying for good documents and a filing workflow when using these services. The table below runs through some of the most common legal decisions these tools can help founders with, and where the need for expert guidance comes in.
Legal decision | What Clerky & Stripe Atlas do | What requires legal judgment | The risk of handling yourself |
Entity choice | Form a Delaware C corp or LLC | Which entity fits your funding path | Paying to convert later, plus delayed QSBS eligibility |
Incorporation & tax ID | File the incorporation and EIN, on Cooley-built templates | None | None, as long as your setup is standard |
Founder equity & vesting | Issue founder stock; Clerky adds vesting | Custom splits, acceleration, and later grants | Terms you can undo only with the holder's consent |
83(b) election | Atlas files your first 83(b); Clerky supports it | A separate 83(b) for each later grant, within 30 days | Ordinary income tax at each vesting date |
IP ownership | Generate formation docs; Clerky adds an IP assignment | Pre-company IP, and assignments from contractors | Buying back rights to your own product |
Fundraising documents | Generate standard SAFEs and convertible notes | Side letters, MFN, pro-rata, and priced rounds | Dilution you didn't plan for |
What legal mistakes do tools like Clerky and Stripe Atlas leave open?
Platforms like Clerky and Stripe Atlas execute based on your instructions, but they don't check whether those decisions fit your company. Consequential decisions that can go wrong without proper guidance often involve entity choice, IP that predates the company, or equity events after formation.
Entity choice: These tools set up an LLC or a C corporation with equal ease, but which one fits depends on how you plan to fund the business. Founder forums often push the S corp for the tax savings, but institutional investors fund Delaware C corporations, so choosing on tax advice alone usually means a paid conversion mid-raise. Starting as an LLC delays QSBS eligibility because the holding period doesn’t start until you convert to a C corporation. Starting as an S-corp is worse: stock originally issued by an S-corp can never qualify as QSBS, even after converting to C-corp status. Only new shares issued after the conversion would be eligible
IP that predates the company: Formation documents can assign IP to the company, but only from the people who sign them. Your product often rests on work from outside that group, like a prototype you built before incorporating or code a contractor wrote. That work belongs to whoever created it until they sign it over in writing. If that person leaves before signing, the company ends up buying back rights to its own product.
Equity events after formation: The tools handle the initial equity paperwork well. The mistakes come later, with new grants, SAFEs, and promised shares. For instance, Atlas files your first 83(b) election (the one-page IRS filing that sets how your stock is taxed as it vests), but each later grant needs its own within 30 days. If you miss that window, the IRS can tax every vesting date as ordinary income.
These tools are a reasonable call for most startups. The gaps they leave are cheap to close early and get more expensive every month they sit, because share prices rise, contributors leave, and tax windows close.

FAQs
What are the most common legal mistakes startup founders make?
The most common expensive legal mistakes are picking the wrong entity for your funding path, leaving pre-company or contractor IP unassigned, and mishandling equity after formation. Those turn into a paid conversion mid-raise, buying back rights to your own product, and ordinary income tax as stock vests. Formation platforms automate the paperwork around all three, and each is still a judgment call the platform can't make for you.
Do I need a lawyer to incorporate my business?
No, not for the incorporation itself. Filing a Delaware C corporation is standardized, and automated formation tools like Clerky and Stripe Atlas, or a careful founder, can do it correctly. You need a lawyer for the judgment the filing doesn't capture, which entity fits your funding plans, whether the IP you built before incorporating is assigned to the company, and how equity grants and 83(b) elections are handled after formation. Left unresolved, those get more expensive to fix, from converting the entity to buying back IP rights.
Should I use Clerky or Stripe Atlas?
Both produce startup-standard documents, so the choice comes down to scope. Atlas bundles formation, tax ID, founder equity, the 83(b) filing, and banking into one automated flow, which suits solo and international founders. Clerky goes deeper on the legal paperwork after formation, covering fundraising and hiring documents, for founders who want one system for early legal work.
Do I still need a lawyer if I use Clerky or Stripe Atlas?
You still need one for the judgment calls, though not for the paperwork itself. A startup lawyer earns the fee on entity choice, assignments for IP created before the company existed, equity grants after formation, and the cleanup of all three before you raise. Most platform-formed companies need a few hours of review rather than a full re-do, and earlier review is cheaper.
Is Stripe Atlas worth it?
For a standard Delaware incorporation, it generally is. You get formation, a tax ID, founder equity, an automated 83(b) filing, and Cooley-collaborated templates for a flat fee. Atlas’s own terms suggest talking to a lawyer if you have unique considerations, and that's a fair read. Foreign founders, unusual ownership splits, and pre-existing IP are the cases the automated flow leaves open.
