Most e-signature platforms charge: per seat, per envelope, API access fees, enterprise contracts We built VisiSign with a different pricing model: $0.10 per envelope via API, no monthly minimum, no contracts, no seat pricing Or $49/month for the hosted team platform: unlimited users, unlimited sends, API included The reason this pricing works is simple: E-signatures are infrastructure now. Twilio doesn’t charge per employee. Stripe doesn’t charge per seat. Cloudflare doesn’t charge by company size. But most e-signature platforms are still priced like 2000s enterprise SaaS. It should…

Woke up today with a 100-degree fever & found out Google is now our competitor. Last week, we started building signwith.co/ - a simple, pay-per-use e-signature tool for people who are struggling with complex e-sign tools. The plan was to build quietly, run a private beta, get 50 users in 15 days, and then do a launch. Easy peasy. But since Google dropped into the e-signature space - we needed to talk. So after 30 minutes of existential dread, a lot of “what are we even doing?” thoughts, and one strong dose of paracetamol we said, screw it. - let’s change gears. So now we're opening our…

We quickly realized that many others shared this same frustration. We are different from other platforms such as Docusign, Dropbox Sign, Adobe Sign, etc in two key ways: 1.…
