Launch screenshots from Product Hunt, Jul 2026
The product is a calculation infrastructure that executes versioned formulas deterministically and issues portable VCC receipts containing the formula, version, inputs, data sources and output to prove how a result was produced. It solves the problem of disputed or unexplainable numbers where spreadsheets, screenshots and logs cannot show which rules and inputs actually ran. It sells to developers, data and engineering teams in B2B companies building financial, quoting and internal tools and AI agent workflows. It is delivered via web tools, a REST API and MCP tools with offline-verifiable signed receipts.
