Listen Labs — Funding & Company Data

Listen Labs exhibits a remarkably aggressive growth trajectory, having secured significant funding within three years of its 2023 founding. The company announced a combined $27 million Seed and Series A round led by Sequoia Capital in April 2025, a clear signal of strong early conviction from a top-tier firm. This was followed less than a year later by a massive $69 million Series B led by Ribbit Capital, bringing the company's valuation to $500 million.

The speed and size of these rounds are indicative of a company hitting critical milestones and demonstrating significant market traction, reportedly reaching an eight-figure annualized revenue run rate just nine months after launch. The investor syndicate is of exceptionally high quality, combining Sequoia's enterprise software expertise with Ribbit's focus on data-intensive companies. The participation of existing investors in the Series B round further validates the company's progress and potential.

While the publicly announced rounds sum to $96 million, the company and its investors have stated a total of $100 million raised. This minor discrepancy may suggest a small, unannounced tranche of funding or a convertible note. Regardless, the financial position is exceptionally strong. This level of capitalization provides a multi-year runway, allowing the company to focus on scaling its enterprise sales, expanding its 30-million-person research panel, and deepening its AI capabilities without near-term financial pressure.
