## The answer, as recorded

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

> ## Short version
> 
> **Dropbox Sign** (formerly HelloSign) is what I'd pick for most startups, and **DocuSign** if your counterparties expect the name on the envelope.
> 
> A caveat on the research: search results for this query are heavily polluted with affiliate/SEO content - several "2026 best of" lists exist mainly to rank their own product #1. I've ignored those and stuck to tools with real track records.
> 
> ---
> 
> ### 1. Dropbox Sign - best default
> Cleanest signing UX in the category, ~$15/user/mo Essentials and ~$30/user/mo Standard, and critically **the API is available at the Standard tier** rather than gated behind an enterprise call. If there's any chance you'll want to embed signing in your own product later, this is the one that won't force a migration. Free tier is 3 requests/30 days.
> 
> ### 2. DocuSign - when the other side of the table matters
> Expensive ($15-45/user/mo depending on tier) and heavier than an early-stage team needs. You buy it anyway when law firms, investors, landlords, and enterprise procurement all already know it - nobody ever bounced a DocuSign envelope for looking sketchy. API pricing requires talking to sales, which is a real drawback for a seed-stage team.
