Sifting through deal flow manually is exhausting.

Right now, doing basic market research means bouncing between company websites, Crunchbase reports, LinkedIn profiles, and news aggregators. You copy a domain name here, paste it there; you find an investor on one tab, then have to open five different tabs just to see their full portfolio history.

With this MCP, your agent manages the entire flow. You give the domain or the person's URL, and Harmonic pulls every piece of required data—the funding rounds, the team background, the current stats—and delivers it all in one clean response.

Get instant validation with the Harmonic MCP.

You don't waste time cross-referencing five different data points. You run `enrich_company` once, and you get firmographics, funding history, and social signals all grouped together for immediate analysis.

What changes is the speed. Instead of a multi-hour research project, you finish complex market due diligence in minutes.

What Harmonic MCP does for your AI

Need to vet a target company or find the next big investment? Harmonic lets you take control of startup intelligence and deal sourcing directly from any AI client. You'll stop manually compiling lists in spreadsheets. Instead, your agent acts like a dedicated Venture Analyst. You can instantly pull firmographic data on a domain, check a person’s professional background using just a LinkedIn URL, or track exactly where a company has raised money over time.

Need to scope out the competitive landscape? Search through millions of companies and filter by specific growth metrics. When you connect your Harmonic account via Vinkius, your agent can search for investor groups, pull up their full portfolio history, and even list recent news for due diligence—all in a single conversation.
