The main SeedLegals alternatives for cofounder agreements are Clerky and Capbase. SeedLegals suits UK and EU founders heading for a raise. Clerky suits US founders who want standard Delaware paperwork. Capbase suits US founders who want incorporation and a live cap table together. All three produce the document. None of them settle what goes in it.
How do SeedLegals, Clerky and Capbase compare?
Pick by country first, then by how much of the back office you want in one place.
| Platform | Built for | Covers | Cap table |
|---|---|---|---|
| SeedLegals | UK and EU founders raising soon | Founder agreements, SEIS and EIS, investment rounds | Yes |
| Clerky | US, Delaware C-corp | Formation, founder stock, SAFEs, hiring documents | No, add a separate tool |
| Capbase | US, Delaware C-corp | Formation, equity issuance, compliance, registered agent | Yes, updates as you sign |
What does SeedLegals do well?
It keeps the whole early life of a UK company in one membership. Its founder agreement product has two stages: a Founder Agreement for founders not yet paid a salary, and a Founder Service Agreement for once you start drawing pay, often around your first funding round. The first defines each founder's role, equity and vesting. The second sets out obligations, director duties and the vesting schedule.
Pricing runs on annual membership tiers, including a Funding tier aimed at your raise, with round documents charged separately. Outside the UK and EU, or before a raise, the fit is weaker.
What does Clerky do well?
It does one job and does it fast: Delaware C-corp formation and the standard paperwork that follows, from founder stock and IP assignment to SAFEs and option grants.
It suits accelerator-track US founders who want standard forms and will call a lawyer for anything unusual.
What does Capbase do well?
It sits between the two. It is US and Delaware focused like Clerky, but it covers incorporation, compliance tracking, a registered agent and equity issuance in one place. Capbase's own comparison with Clerky puts its difference plainly: generating an equity document updates your live cap table automatically, so there is no manual data entry.
What do none of these tools do?
They do not help you decide the terms. A generated agreement records whatever you had agreed when you filled in the fields. If you never discussed who makes which calls, what full-time means to each of you, or what happens if one of you steps back, the document formalises a guess.
Work through the substance before you open any template:
- The equity split and the reasoning behind it. See how to split cofounder equity.
- Vesting, cliff and what happens to unvested shares if someone leaves.
- Roles and who has the final call in each area.
- How you break a deadlock.
- Exit terms, good leaver and bad leaver.
Our cofounder agreement checklist covers each clause.
Where does Founders Align fit?
Before the legal platform. Founders Align does not produce binding legal documents. Each co-founder answers two short question sets privately, and we show where your answers match and where they differ. You then agree roles, decisions, equity and exits in a Blueprint you both sign and update as the company changes.
Take the Blueprint to SeedLegals, Clerky, Capbase or your lawyer, and the template gets filled with terms you actually agreed. For a quick read on your own gaps, start with the cofounder alignment check. To see the clauses before you pay for a platform, read our free founders agreement templates.
Frequently asked questions
- What is the difference between SeedLegals and Clerky?
- SeedLegals serves UK and EU founders and bundles founder agreements, a cap table and fundraising paperwork such as SEIS and EIS into one membership. Clerky serves US founders and focuses on Delaware C-corp formation and standard paperwork like founder stock, SAFEs and hiring documents. Clerky does not run a live cap table, so founders often add a separate equity tool.
- Is Capbase a good SeedLegals alternative?
- For US founders, yes. Capbase is US and Delaware focused like Clerky, but it covers more ground like SeedLegals. It handles incorporation, compliance tracking and equity issuance, and updates your cap table automatically when you sign equity documents. UK founders who plan to raise with SEIS or EIS are better served by SeedLegals.
- Do I still need to agree terms if I use SeedLegals, Clerky or Capbase?
- Yes. Each platform generates a sound legal document, but the document only records what you already decided. None of them help co-founders work out roles, decision rights, the equity split or what happens if someone leaves. Have that conversation first, or the signed agreement simply formalises a guess.
- Can I use a legal platform and Founders Align together?
- Yes. Use SeedLegals, Clerky, Capbase or a lawyer to produce the binding, jurisdiction-correct document. Use Founders Align to find where you and your co-founder disagree and to agree roles, decisions, equity and exits in a Blueprint you both sign. The Blueprint then tells the lawyer or template what to say.
