About
Harmonic.ai is an AI-powered startup and private company intelligence platform founded in 2020 in New York City, built to give venture capital investors and institutional deal teams real-time visibility into the global private company landscape. The company's core technology aggregates signals from funding announcements, hiring patterns, product launches, regulatory filings, and web data to build continuously updated profiles on private companies before they become publicly known fundraising targets — giving investors an early-signal advantage in competitive deal sourcing.\n\nThe Harmonic platform provides investors with a searchable database of more than 30 million companies and 190 million people, combined with proprietary scoring models that identify breakout companies at early stages of growth. Key features include AI-generated company summaries, investment fit scoring, alumni and network tracking, and automated portfolio monitoring. The platform is used by leading venture firms including Accel, Greylock, and Menlo Ventures, which validates its utility at the top of the institutional investor market.\n\nHarmonic has raised approximately $30 million in total funding, reflecting strong investor conviction in the intelligence layer for private market investing. As venture capital competition for the best deals intensifies and AI dramatically expands the surface area of relevant startup signals, Harmonic's data infrastructure and scoring models address a critical bottleneck for investment teams: finding non-consensus opportunities before they become consensus. Its positioning at the intersection of AI and venture intelligence gives it a natural growth path as private market data becomes increasingly central to investment strategy.

About
MongoDB is a leading document-oriented NoSQL database company providing a flexible, developer-friendly data platform for modern applications that require horizontal scalability, flexible schemas, and rich query capabilities.

The company is listed on NASDAQ and generates approximately $1.7 billion in annual revenue.
