SeedLegals is the dominant platform for UK startups and increasingly popular with US founders who want a single system for their entire fundraising workflow. The platform automates SAFE generation end-to-end — fill in the terms, invite your investor, and they sign in the same browser session. No PDFs emailed back and forth. The built-in cap table updates automatically when SAFEs convert, so you always know your dilution in real time. Where SeedLegals stands alone is readiness infrastructure: the Series A Readiness Checklist and SAFE Dilution Calculator let you stress-test your terms before you pitch.
Clerky is a solid choice if you're a Delaware C-Corp raising from US angels and you need a well-structured, lawyer-reviewed template library. The documents are clean and defensible — investors who've seen a lot of Clerky deals trust them. The catch is the pricing model: you pay per fundraising event, not an annual subscription, so a typical pre-seed plus seed round can cost $1,600+ before you've closed a single dollar. There's no cap table management built in, which means you'll need a separate tool (Carta, Pulley, or a spreadsheet) to track your equity. UK founders are out entirely — Clerky is Delaware-only.
Stripe Atlas is primarily an incorporation service, not a fundraising platform. The $500 fee covers setting up your Delaware C-Corp, registered agent, and initial paperwork — it's genuinely excellent value for that specific job. The SAFE template included is basic: it's a download, not a workflow. You'll handle negotiation, signing, and tracking outside the platform entirely. There's no cap table tool (Atlas partners with Carta, which costs extra), no investor portal, and nothing resembling Series A readiness tooling. Use Atlas to incorporate, then use a different platform to run your actual fundraise.
Capbase is the closest competitor to SeedLegals in the US market: similar pricing, automated SAFE generation, and a built-in cap table. The platform has a clean UI and handles the basics of a pre-seed raise well. Where it falls short: no UK support (a hard stop for international founders), weaker Series A tooling, and a smaller network of investors who are familiar with it. Capbase has also had intermittent reliability issues and its investor portal is less polished than SeedLegals. If you're US-only and want an alternative to Clerky's per-transaction model, Capbase is worth evaluating — but SeedLegals wins on breadth of tools.
Most SAFE platforms solve one problem. SeedLegals solves the whole journey — from your first angel cheque to Series A readiness.
