Harmonic is used by teams like Brex, Sequoia, Index, a16z, MongoDB, Notion, and Bloomberg to connect startups with the capital and resources that they need to drive growth.
"Harmonic’s filters feed us companies based on aggregated, publicly-available information. So it’s a relatively quick search—a matter of minutes or less—to decide whether it makes sense to reach out and meet the founder directly. Typically, we surface 20 to 50 companies a week through Harmonic, and it’s a roughly 30% conversion rate to outreach for scheduling a first call.”
