What Harmonic.ai does

Harmonic.ai is an AI-native startup discovery and private-market intelligence platform, founded in 2018 and headquartered in San Francisco with an additional office in New York. The company's proprietary knowledge graph covers more than 30 million companies and 190 million people, sourced from legal filings, business registries, and social platforms, and is refreshed continuously with time-series tracking of headcount, funding rounds, web traffic, and social signals — positioning the platform to surface earliest-stage private companies ahead of incumbents such as PitchBook, Crunchbase, and Tracxn. Core capabilities are delivered through three access tiers — an Enterprise Console with AI search tools, REST and GraphQL APIs for programmatic integration, and Bulk Data delivery to customer data warehouses — and are reinforced by a purpose-built Model Context Protocol (MCP) server, a Scout AI agent launched in 2025, a Saved Search API, an Enrichment API, Network Mapping across email/calendar/LinkedIn, People Alerts, and a Chrome Extension for in-browser intelligence.

The platform primarily serves venture capital and growth equity funds (including Sequoia, Kleiner Perkins, NEA, Bessemer, Accel, First Round, FirstMark, Battery, Pear, Khosla, Forerunner, and General Catalyst), and has expanded into corporate development teams, GTM/sales organizations, recruiting firms (Quantum Talent), and university entrepreneurship centers (Polsky Center at the University of Chicago). Revenue is generated through annual subscriptions (Enterprise Console, Bulk Data) and usage-based API access, with custom quote-based pricing across enterprise field sales, API-first developer distribution, and product-led growth via the Chrome Extension. The company is ISO/IEC 27001:2022 certified and SOC 2 Type II compliant, and has raised approximately $30M in cumulative funding through a Series A led by Sozo Ventures in November 2022, with prior participation from Craft Ventures and others.

Core offering

Harmonic.ai provides an AI-native startup discovery and private market intelligence platform built on a proprietary knowledge graph of 30M+ companies and 190M+ people. It sells access to this data through an Enterprise Console subscription, REST/GraphQL APIs, bulk data delivery to customer warehouses, and a Chrome Extension, and layers on Scout, an AI agent that performs natural-language market mapping, momentum evaluation, research, and outreach drafting for venture capital, growth capital, corporate development, and GTM buyers.

Product overview

Harmonic.ai offers a unified, AI-native startup intelligence platform centered on a core product (the Harmonic.ai startup discovery engine) that covers 30M+ companies and 190M+ people. The platform is delivered through three access tiers: the Enterprise Console (with 29M+ company records and AI search tools), the Harmonic API (REST and GraphQL endpoints for programmatic integration), and Bulk Data (direct delivery to data warehouses). On top of this core, the platform layers several modules: Scout (an AI agent that runs Find/Screen/Act workflows), a Saved Search API, an Enrichment API, a Chrome Extension for in-browser insights, Network Mapping (syncing email, calendar, and LinkedIn connections), and People Alerts. The Harmonic MCP Server, Zapier, and n8n connectors extend the platform into AI assistants and no-code workflows. Harmonic Hot 25 Startups is a quarterly ranking publication derived from aggregated investor interest across the platform's user base.

Broad incumbents

• S&P Capital IQ Pro: Capital IQ Pro is S&P Global's enterprise private-company and capital-markets intelligence platform, deeply embedded in investment banking, PE, and corporate strategy workflows. It is a broader incumbent that overlaps with Harmonic's corporate-development and growth-capital use cases from a much larger base.
• Apollo.io: Apollo.io is a sales-intelligence and prospecting platform used by GTM teams to identify and enrich target accounts. It overlaps with Harmonic's GTM/Account-Based-Sales use case but is broader in scope and is used by many of the same sales and corporate-development buyers.
