Questions & Answers

As answered by people managing Paperspur and DevFinanceTools.

What makes your product unique?

Paperspur's answer

Most tools focus on just one utility—Bitly for links, DocSend for document analytics, DocuSign for contracts, and WeTransfer for temporary file sends. Paperspur unifies all these into a single, premium, privacy-first dashboard. Furthermore, our SpurShare feature is unique: it allows zero-storage browser-to-browser P2P file transfers up to 100MB via WebRTC. The files stream directly between devices and never touch our servers, providing absolute security and privacy with zero trace.

Why should a person choose your product over its competitors?

Paperspur's answer

Cost Efficiency: Instead of paying $150+/month for DocSend or DocuSign, you get PDF gating, contract signing, and data rooms in one place for a fraction of the cost. Absolute Privacy: With WebRTC P2P sharing and AES-256 encrypted vaults, you retain total ownership. We host data in the EU and do not sell user analytics. Actionable Analytics: Get visual page-by-page reader focus timelines and heatmaps so you know exactly which sections of your proposal or pitch deck captured a prospect's attention. Developer Integration: Custom branded domains, webhook configurations, and API keys are built-in from day one.

How would you describe the primary audience of your product?

Paperspur's answer

Founders & Startups: Pitching investors, secure deck sharing, and pre-sign NDA collection. Sales & Account Executives: Sending proposals, contracts, and marketing collateral while tracking buyer engagement. Privacy-First Professionals (HR, Legal, Finance): Securely sharing onboarding material, compliance forms, or financial assets under AES-256 encryption. Developers: Seeking programmatic control over shortened links, custom domains, and signature workflows.

What's the story behind your product?

Paperspur's answer

I built Paperspur out of frustration with expensive software bills and data privacy concessions. I found subscribing to multiple expensive SaaS platforms to simply share pitch decks and sign contracts. I realized I could build a unified, security-first document workspace. During development, to solve the massive cloud storage overhead of temporary user file transfers, I built a WebRTC chunking relay. This allowed users to transfer files up to 100MB directly browser-to-browser (SpurShare), keeping our cloud storage bills at $0 and user data completely private.

Which are the primary technologies used for building your product?

Paperspur's answer

Backend: FastAPI (Python), WebSockets (for WebRTC signaling and ICE relays), PostgreSQL SQLite, and Redis. Frontend: Vanilla HTML5, CSS3 (with responsive custom properties), and native Javascript (using browser WebRTC APIs and pdf.js for document rendering and focus tracking). Self-Hosting: Docker and Docker Compose.

Who are some of the biggest customers of your product?

Paperspur's answer

Paperspur is currently in public beta, focusing on early adopters:

Seed and pre-seed startup founders using it for secure fundraising pitch decks. Independent real estate brokers distributing disclosure booklets and collecting digital contract signatures. Creative design agencies sharing drafts and tracking client review durations. Boutique consulting firms using secure vaults for confidential strategy sharing.
