The answer, as recorded

## For a startup, here's what I'd actually pick **1. Dropbox Sign (formerly HelloSign) - my default recommendation for most startups.** Cleanest UX of the mainstream options, no per-envelope send limits on paid plans, and Essentials starts around $15-20/mo. The big reason I put it first: if you later need to embed signing *into your own product*, it has the best-documented API of the big names (SDKs in 6 languages, free unlimited testing with `test_mode=1`). You won't have to migrate vendors when you go from "signing our own contracts" to "our users sign things in our app." Note the Standard tier has a 2-seat minimum, so it's effectively ~$50/mo there. **2. PandaDoc - if signatures are attached to sales.** Cheapest real entry point (~$19/seat Essentials) and it's genuinely a document-creation + proposal tool, not just a signing tool: templates, content library, pricing tables, engagement tracking. If your startup is sending proposals, SOWs, or quotes, this replaces two tools. Caveat: the Starter tier strips out CRM integrations, custom branding, and approval workflows, so budget for the next tier up if you're using HubSpot/Salesforce. **3. SignWell - the value pick.** $10/mo for unlimited documents, plus a free tier of 3 docs/month. Solid REST API with transparent per-document API pricing (~$0.85/doc, dropping with volume) rather than a $3k/yr commitment. This is the one I'd name if you're pre-revenue and just need NDAs, offer letters, and SAFEs signed. **4. BoldSign - best free tier.** 25 signature requests per month free, with advanced signer authentication, paid from $15/mo. Good if your volume is genuinely low and you want to spend $0 without a self-hosting project. **5. Documenso - if you're an eng-heavy team that wants to self-host.** Open source, free unlimited when self-hosted, eIDAS and 21 CFR Part 11 compliant. Cloud with full API access is ~$30/mo. Pick this if data residency or "no third party holds our contracts" actually matters to you; otherwise the ops burden isn't worth it. **Who I'd skip:** **DocuSign**, unless a counterparty or your legal/procurement team specifically demands it. It's the enterprise standard and it's the most legally battle-tested, but month-to-month plans cap you at ~10 sends/month (100/year) with overage charges, and Standard runs $45/mo. You're paying for brand recognition and compliance depth that most seed-stage companies don't need yet. **Zoho Sign** is reasonable if you're already in the Zoho suite, but API access is gated to the $22/user/mo Enterprise plan. **The one-line version:** start on SignWell if you're cost-sensitive, Dropbox Sign if you expect to embed signing in your product, PandaDoc if your docs are sales proposals. One thing worth checking before you commit: all of these are legally binding under ESIGN/UETA (US) and eIDAS (EU) for ordinary commercial contracts, but if you're in a regulated space - healthcare, life sciences, financial services - confirm the specific compliance certifications (HIPAA BAA, 21 CFR Part 11, qualified signatures under eIDAS) on the exact tier you're buying, not just the vendor's marketing page. Those are often gated behind higher plans.
