Heron GTM is a B2B outbound agency that builds and runs outbound for B2B companies, from buying signals to booked calls.
Heron GTM is run by its founder, Louis Seyns. Before this, he was Growth Lead at Exhibitly.ai (built their outbound from scratch) and Digital Marketing Analyst at Accenture (for ExxonMobil).
A heron stands still, watches, and strikes at the right moment. We watch for the buying signal, then reach out with a reason: the target list, buying signals, email sequences and deliverability run as one system, not scattered tools.
Heron GTM is based in Seville, Spain, and works with B2B companies in the United States and Europe. It started in May 2026.
