About ProposalOS

ProposalOS was built out of frustration with the proposal process. Too many freelancers and agencies spend hours crafting proposals in Google Docs, only to have no idea if clients even read them.

We believe proposals should be fast to create, beautiful to read, and smart enough to tell you what happens next. That's why we built an AI-powered platform that drafts proposals from a brief, tracks every client interaction, and handles payments automatically.

Our Mission

Help every freelancer, agency, and consultant close more business with less effort. We want to eliminate the busywork of proposal writing so you can focus on doing great work for your clients.

Built With

ProposalOS is built with modern, open-source technologies: Next.js 16, React 19, Supabase, Stripe, and OpenAI. We believe in using the best tools available and contributing back to the community.
