## The answer, as recorded

Asked on 2026-09-26 through Claude (Anthropic) with web search (model claude-opus-5).

> ## My picks, in order
> 
> **1. Dropbox Sign (formerly HelloSign)** - my default recommendation for most startups. Cleanest signing UX, fastest to set up, and by far the best-documented developer API if you ever want signing *inside* your product. API tiers start around $20/mo for ~20 envelopes and scale to ~$100/mo at 5,000+, which is unusually transparent - DocuSign, PandaDoc and SignNow all make you talk to sales for API pricing. Standard is ~$30/user/mo. ([StackScored](https://www.stackscored.com/pricing/e-signature/), [TurboDocx](https://www.turbodocx.com/blog/best-esignature-apis-2026))
> 
> **2. DocuSign** - not because it's the best value (it isn't: ~$15-45/user/mo and the most feature-gated), but because it's the one your counterparties' lawyers, landlords, and enterprise procurement teams already recognize. If you're raising, signing a lease, or selling upmarket, the lack of friction is worth the premium. Don't make it your *only* tool at seed stage. ([PandaDoc comparison](https://www.pandadoc.com/blog/docusign-vs-adobe-sign-vs-hellosign/))
> 
> **3. PandaDoc** - pick this if signing is really the last step of a *sales* motion. You get proposals, quotes, templates, and a content libr
