5. BoldSign mentioned
   BoldSign - the developer's pick when signing goes inside your product.
6. Dropbox Sign's mentioned
   Around $30/mo for the API tier with a free sandbox and roughly $0.75/document, which undercuts Dropbox Sign's embedded pricing by an order of magnitude.
7. Documenso mentioned
   Documenso - open source (AGPL-3.0), self-hostable.

9. Adobe Acrobat mentioned
   What I'd skip unless there's a specific reason: Adobe Acrobat Sign (~$15/user/mo) unless you're already deep in Creative Cloud, and Zoho Sign unless you're already on Zoho One - both are fine, but neither wins on its own merits.

The answer, as recorded

For a startup, the honest answer is that this is a commodity - pick based on volume and whether you need signing inside your own product. Here's who I'd actually name, in order: **1. Dropbox Sign** (formerly HelloSign) - my default for most startups. Cleanest UX of the mainstream options, a genuinely usable free tier (3 requests/month), and Essentials runs about $15/user/mo. It does the one job well without trying to become a CRM. Caveat: if you want *embedded* signing in your own app, their API jumps to roughly $300/mo - at that point look at #4. **2. SignWell** - the best value if you're cost-sensitive. Free tier of 3 docs/month, paid plans in the $10-$30/mo range, and the API is pay-as-you-go after 25 free docs/month rather than a big platform fee. For a seed-stage company sending a few dozen contracts a month, this is the cheapest real option. **3. PandaDoc** - pick this one *only if* you're a sales-led startup. At ~$19/user/mo Starter it's more than a signature tool: templates, proposals, pricing tables, quote-to-close. If your documents are sales proposals, it replaces two tools. If you just need signatures on offer letters and NDAs, it's overkill. **4. BoldSign** - the developer's pick when signing goes inside your product. Around $30/mo for the API tier with a free sandbox and roughly $0.75/document, which undercuts Dropbox Sign's embedded pricing by an order of magnitude. Strong multi-tenant and white-label support, which matters if you're reselling signing to your own customers. **5. Documenso** - open source (AGPL-3.0), self-hostable. Worth it if you have data-residency or compliance requirements that make a US SaaS vendor awkward, or you just want to own the stack; self-hosting lands under ~$500/yr on a small VPS plus object storage. Their cloud is *not* a bargain (~$25-40/mo, $250/mo for the API tier), so the value here is in self-hosting. Expect to spend engineering time. **6. DocuSign** - name recognition, and the one to choose when your counterparties are enterprises or you're in a regulated industry where "we use DocuSign" ends the procurement conversation. Otherwise skip it: Standard is around $30/user/mo and the Personal plan caps you at 5 envelopes/month. **What I'd skip unless there's a specific reason:** Adobe Acrobat Sign (~$15/user/mo) unless you're already deep in Creative Cloud, and Zoho Sign unless you're already on Zoho One - both are fine, but neither wins on its own merits. **Shortest version:** Dropbox Sign if you want it to just work, SignWell if you're watching every dollar, BoldSign if it's going in your product, DocuSign if your customers' legal teams demand it. One caveat on the numbers: these come from comparison sites and review aggregators, and e-signature vendors re-price and re-tier frequently. Treat the figures as the right ballpark for shortlisting, then confirm on the vendor's own pricing page before you commit - especially the per-envelope and API limits, which are where the surprise costs live.
