## 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
