## The answer, as recorded

Asked on 2026-10-17 through Claude (Anthropic) with web search (model claude-opus-5).

> ## 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://
