As answered by people managing LeetCode and TrackDoc.site.
TrackDoc.site's answer:
TrackDoc strips away enterprise bloat and delivers ultra-fast, zero-friction proposal tracking. While legacy tools require complicated setups and heavy interfaces, TrackDoc lets you upload a PDF, generate a clean link in seconds, and track second-by-second reader engagement per page with virtually zero learning curve.
TrackDoc.site's answer:
Most document tracking tools (like DocSend or PandaDoc) charge steep monthly enterprise subscriptions ($65+/user/mo) and bundle complex features that small teams don't need. TrackDoc focuses on what actually closes deals: blazing-fast viewer loading speeds, crystal-clear page heatmaps, real-time open alerts, and a fair, transparent pricing model with a permanent free tier.
TrackDoc.site's answer:
B2B sales professionals, digital agency owners, freelance consultants, and startup founders who regularly send commercial proposals, pitch decks, or service quotes and need to know the exact right moment to follow up.
TrackDoc.site's answer:
TrackDoc was born out of frustration with the 'proposal black hole'—spending days crafting detailed business proposals, emailing them as static PDF attachments, and waiting in total silence. We wanted to know if prospects actually read the pricing, which slides they skipped, and when they were reviewing the document. Existing tools felt too complex and overpriced, so we built TrackDoc to give every sales professional a clear, data-driven advantage.
TrackDoc.site's answer:
Next.js, React, TypeScript, Supabase, PostgreSQL, and Vercel Edge Infrastructure.
