The proposal

company.
We build software and services for teams that answer RFPs, tenders, and security questionnaires.
Procurement is huge. The response process is still manual.
Procurement is a $13 trillion market. In the DACH region alone, 291,000 formal tenders are issued every year. Responding to them still means searching old proposals, chasing subject-matter experts, and fixing Word documents late into the night.
Many capable teams lose before the buyer can judge their work. They miss the tender, start too late, submit weak answers, or spend the final hours cleaning up formatting instead of improving the offer.
AI changes who can respond, and how often.
A good first draft is no longer the bottleneck. The harder work is using the right evidence, staying compliant, keeping the document consistent, and getting a team to a submission they can stand behind.
Zephior works on that full path: finding relevant opportunities, turning company knowledge into answers, and helping teams submit stronger responses without rebuilding everything from scratch.
From opportunity to submission.
Discover
We monitor procurement portals and match tenders against what a company can credibly sell. Good opportunities surface earlier, with less manual searching.
Respond
We turn past proposals, product material, policies, and expert input into usable responses. Teams can use the platform directly or work with our proposal specialists when the deadline is tight.
Win
Strong companies should not lose because the response process broke down. We help teams qualify faster, answer better, and get the final document into shape.
Built by people who have done the work.
We started Zephior in Lausanne in 2024 after seeing the same pattern again and again: strong teams losing deals because the proposal process failed before their work could speak for itself.
