Details
What is Centilio Sign?
Centilio Sign is the first product from Centilio, a bootstrapped Canadian startup founded April 2024 by Ravi Arul, a growth marketer who has scaled multiple SaaS products. It’s a no-frills e-signature tool: upload a document, drag and drop fields, and send — recipients sign from any device without an account. Features include reusable templates, bulk sending, real-time tracking with automatic reminders, team roles and shared template libraries, AES-256 encryption, password protection, audit trails, and a REST API plus webhooks for custom workflows. It integrates with Google Drive, Dropbox, HubSpot, Pipedrive, Zoho, and OneDrive. The product has no TrustRadius listing and a thin 3.5/5 AppSumo score across just 4 reviews. The AppSumo lifetime deal ($39–$139) is currently sold out.

Who is it for?
- Small businesses and freelancers who want unlimited e-signatures without per-document fees
- Sales teams sending proposals, quotes, and purchase agreements that stall in inboxes
- Real estate professionals handling purchase agreements and onboarding paperwork
- Teams that want e-signature built into Google Drive, HubSpot, or Pipedrive workflows
- Budget-conscious buyers who find DocuSign and PandaDoc pricing painful
Who is it NOT for?
- Anyone who needs in-person or tablet signing sessions
- Teams with international or non-Latin-script documents — no RTL support and limited compliance coverage
- Enterprises that need SOC 2, dedicated support SLAs, or deep audit/compliance features
- Buyers who rely on AppSumo review volume to make decisions — 4 reviews isn’t enough
- Users who need native mobile or desktop apps
The Bottom Line
Centilio Sign does the core job — upload, drop fields, send, track, remind — at a price that undercuts DocuSign and PandaDoc dramatically, and the unlimited-envelope lifetime deal was genuinely competitive while it was live. But this is a micro-startup with ~30 customers, a thin 3.5/5 review base, and some genuinely sloppy site marketing that makes me want to verify everything before trusting it with contracts. At $39 it was a low-risk experiment inside the 60-day window; now that it’s sold out, I’d only circle back if it returns and the review base thickens.
