Digital Signatures, your way.
Use ctSignature as a ready-to-go web app, or plug into the optional API. Reusable templates, multi-signer flows, webhooks, tamper-evident PDFs, and pay-as-you-go pricing.
Any business that signs documents.
Real estate brokerages, law firms, mortgage and lending teams, HR departments running onboarding, healthcare providers collecting consent, construction contractors signing change orders, nonprofits, financial advisors. The list is long because the need is universal — and most teams don't need (or want) to pay enterprise prices for it.
ctSignature is end-user-first. Sign in, upload, send. The API is there if you need it.
