OpenFunnel(YC F24)

OpenFunnel(YC F24) is a real-time B2B intelligence platform designed for sales and go-to-market teams. It moves beyond static lead lists by continuously monitoring a vast database of companies for live signals that indicate buying intent. Instead of providing a generic directory, it surfaces accounts at the precise moment they show activity like new hiring initiatives, social media engagement, or technographic changes that suggest a need for your product. The core function is to replace outdated prospecting methods with a dynamic, evidence-based system.

The platform works by analyzing a wide range of public data sources to build a live intelligence layer. It structures information around key entities: companies (accounts), their employees (people), and the live events (signals) associated with them. A major differentiator is its focus on providing context; every insight includes references and reasoning, so users understand why an account was flagged. It is built as an API-first service, making it particularly suited for integration into automated sales workflows and AI agents that require fresh, actionable data.

Sales professionals and business development representatives working in B2B sectors will find OpenFunnel(YC F24) most useful. It is optimized for teams that rely on trigger-based outreach rather than cold calling from stale lists. Practical use cases include a salesperson discovering companies that have just posted job listings related to their solution, or a marketer researching a target enterprise account to understand recent organizational changes and key stakeholders before launching a campaign.
