Questions & Answers

As answered by people managing ReviewStudio and SignProof.dev.

Why should a person choose your product over its competitors?

It also offers a free plan, straightforward paid plans, client-facing review links, and developer capabilities on the Business plan.

What makes your product unique?

SignProof.dev's answer:

SignProof combines client approval workflows and PDF electronic signatures in one workspace. Teams can send deliverables for review, collect revision requests, preserve exact-version history, capture client sign-off, and retain approval records. A separate document-signing workflow handles finished PDFs with recipients, signing fields, signed PDFs, and Signing Records. SignProof also supports branded client experiences, team collaboration, custom domains on eligible plans, and developer workflows through its REST API and signed webhooks.

How would you describe the primary audience of your product?

SignProof.dev's answer:

SignProof is built for agencies, freelancers, consultants, creative teams, web designers, developers, contractors, and other client-facing teams that need a clear way to collect feedback, manage revisions, obtain final approval, and send PDFs for electronic signature.

What's the story behind your product?

SignProof.dev's answer:

SignProof was created to solve a common problem in client work: feedback, revised versions, approvals, signatures, and proof of what was accepted often end up scattered across email, chat, files, and separate signing tools. SignProof brings those steps together so teams can keep the work, the client decision, and the approval or signing record connected from review through final delivery.

React, TypeScript, Firebase, Google Cloud, Cloud Run, Firestore, Stripe, and Resend.
