Harmonic is a startup database for venture, growth and corporate development teams, with console, API and bulk data access. LeadMarmot is the lead generation agent for agencies: every weekday morning, the companies that raised, launched or started hiring, what each needs most, the opening line, and how to reach them.

Everything in the Harmonic column comes from Harmonic's own pages on 2 November 2026, linked below. "Not stated on their site" means we did not find it there, not that the product lacks it. LeadMarmot does not do everything: no investor or round history beyond the signal itself; no phone numbers; no search across a historical database: the API serves leads by day and by need; cRM delivery through webhook, Zapier, Make or n8n, not a native app.
You are an investor or a corporate team sourcing companies at scale.
You are an agency that needs this morning's companies with a reason to write to each.

Ten real leads with the need, the opener and every contact path. Then the whole week the moment you sign up.
