Proven is building the infrastructure for how organizations find, trust, and work with the right partners — whether that’s a startup choosing a vendor, a VC connecting portfolio companies, or a government promoting its exporters to the world. Today, vendor discovery, export promotion, and FDI attraction are mostly done with spreadsheets, static directories, and manual intros. It’s slow, relationship-dependent, and almost impossible to keep up to date. Governments struggle to showcase the full strength of their ecosystems, agencies can’t see which companies are actually winning deals, and foreign investors don’t know who they can trust. We’re fixing that. Proven is a networked platform where organizations can create living “trust networks” of companies: verified vendors, exporters, and local partners connected through real relationships, data integrations, and AI-driven matching. Governments and economic development agencies use Proven to: • Build modern, searchable directories of trusted local companies and exporters • Showcase those companies to foreign buyers and investors • Match international demand with vetted local supply in real time • See what’s working through data, not guesswork The hard problems we’re solving: making trust and track record machine-readable, turning scattered relationships into usable network data, and giving institutions a way to build and operate trade and investment networks that are dynamic, global, and actually used. In short, we’re rebuilding how economic ecosystems connect and grow.
