The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd try them: **1. Dropbox Sign (formerly HelloSign) - my default pick for most startups.** Cleanest UX of the mainstream tools, generous templates, and the best developer story if you ever need signing *inside* your product. Business plans run roughly $15-25/user/month depending on tier; the API is a separate line item starting at $75/mo for ~50 signature requests, and it's free in test mode while you're building ([API pricing](https://sign.dropbox.com/products/dropbox-sign-api/pricing), [Sign pricing](https://sign.dropbox.com/products/dropbox-sign/pricing)). They also run a startup-specific API program. **2. DocuSign - when the other side of the table expects it.** It's the thing investors, landlords, banks, and enterprise procurement already know, which matters for SAFEs, leases, and your first enterprise contracts. Downside is price and envelope caps: Personal is $11/mo but only 5 envelopes/month; Standard is $30/user/mo with ~100 envelopes per user per year, and you pay overages past that ([official pricing](https://ecom.docusign.com/plans-and-pricing/esignature), [overage FAQ](https://support.docusign.com/s/articles/FAQ-Docusign-overage-charges?language=en_US)). For a pre-seed team sending a handful of docs, that's often overkill. **3. PandaDoc - if signatures are the last step of a sales motion.** Proposals, quotes, pricing tables, and signing in one tool, with CRM integrations. Starter is around $19/user/mo and Business around $49/user/mo ([comparison](https://www.stackscored.com/pricing/e-signature/compare/dropbox-sign-vs-pandadoc/)). Pointless if you're just signing NDAs and offer letters; genuinely good if a rep is building a doc per deal. **4. SignWell - the cheap/free answer.** Free tier gives 1 sender, 1 template, 3 docs/month; paid is roughly $12-15/mo ([pricing](https://costbench.com/software/e-signature/signwell/)). If you're sending under ~20 documents a month - which is most seed-stage companies - this is the honest recommendation over a $360/year DocuSign seat. **5. Documenso - if you want to self-host or embed it yourself.** Open source (AGPL-3.0), TypeScript, PAdES-compliant PDF signatures, webhooks, Docker/Railway deploys, no per-document fees ([project](https://www.opensourcealternatives.to/item/documenso), [self-host guide](https://livemy.app/blog/self-host-documenso)). Real tradeoff: you own the uptime, key management, and audit-trail defensibility. Worth it for data-residency requirements or high document volume, not for a 5-person team signing NDAs. Also fine, just not where I'd start: **Zoho Sign** (very cheap if you're already on Zoho), **Adobe Acrobat Sign** (if your workflow is already Acrobat-heavy), **signNow** (good value, clunkier UI). Practical notes: ESIGN/UETA and eIDAS make plain electronic signatures legally binding for the documents startups actually sign, so you don't need "qualified" signatures unless you're dealing with EU regulated contracts or real estate. The thing that bites people is envelope caps, not the base price - count your monthly volume before picking a tier. One caveat on my sources: several of the "best of 2026" comparison pages that surfaced are affiliate/SEO content with pricing that drifts from reality. The DocuSign and Dropbox Sign numbers above are from their own pricing pages; the PandaDoc and SignWell figures are from third-party trackers, so confirm those on the vendor sites before you commit.
