The answer, as recorded

## Short answer For most startups: **Dropbox Sign** if you want the best value and a real API; **DocuSign** if you want zero friction with investors, lawyers, and enterprise customers. --- ### 1. Dropbox Sign (formerly HelloSign) - my default pick Cleanest signing UX of the bunch, unlimited documents on paid plans, and the **best-documented API** if you ever want to embed signing into your own product (very common for startups with a customer onboarding flow). Essentials is **$15/mo** for one user, Standard **$25/user/mo** for teams. ([pricing](https://sign.dropbox.com/products/dropbox-sign/pricing)) Worth noting: a couple of comparison sites are quoting "$10.05/mo" for Dropbox Sign - that doesn't match the official page, so budget for $15. ### 2. DocuSign - the one nobody will question It's the industry default, and that matters more than it should. Law firms, landlords, enterprise procurement, and most investors already use it, which means less back-and-forth on SAFEs, NDAs, and employment agreements. Personal is **$11/mo** but capped at **5 envelopes/month**; Standard is **$30/user/mo** with ~100 envelopes/user/year, and overages are billed per envelope. ([pricing](https://ecom.docusign.com/plans-and-pricing/esignature)) Watch that envelope cap - it's the usual source of surprise bills. ### 3. SignWell - cheapest credible option Free tier gives you **3 documents/month, 1 template**; the Light plan is **$10/mo annually** for unlimited documents. If you're pre-revenue and sign a handful of contracts a month, this is genuinely enough. First 25 API documents/month are also free. ([pricing details](https://www.signwell.com/resources/best-free-esignature-software/)) ### 4. PandaDoc - if you're sales-led Not really an e-signature tool; it's a proposal/quote platform with signing attached. Right call if your team builds custom pitch documents and wants templates, pricing tables, and analytics in one place. **$19/user/mo** Starter, **$49/user/mo** Business. Its free e-sign tier has no envelope limit, which is unusual. Overkill if you just need signatures. ### 5. Documenso - open source, self-hosted AGPLv3, no per-seat or per-document fees - you just pay hosting (~$5-10/mo on Railway). Pick this if you have data-residency requirements, a privacy-sensitive customer base, or an engineer who'd enjoy owning it. Their hosted plan is **$25/mo**, which defeats the purpose; self-host or skip. ([Documenso on Railway](https://railway.com/deploy/documenso-signing)) ### 6. Adobe Acrobat Sign / Zoho Sign - only if you're already in the ecosystem If you're paying for Adobe CC or Zoho One, you likely already have signing included. Don't buy a seventh tool before checking. --- **One practical note:** for fundraising specifically, you may not need any of these. **Carta**, **Clerky**, and **AngelList** generate and collect signatures on SAFEs and incorporation docs natively. Many startups buy e-signature software for a job their cap table tool already does. **If I had to pick one and move on:** Dropbox Sign Essentials at $15/mo. Switch to DocuSign only when a counterparty insists.
