B2B outbound, from buying signals to booked calls.

Heron GTM is a B2B outbound agency that builds and runs outbound for B2B companies, from buying signals to booked calls. We build the target account list, watch for buying signals, write the email sequences and look after deliverability, and we run all four as one system, so outbound keeps running week after week instead of as a side project. For the first three months we are judged on qualified meetings, reported weekly. Heron GTM was founded by Louis Seyns, who built outbound from scratch in his previous growth role. We are based in Seville, Spain, and work with established companies and startups in the United States and Europe. More at herongtm.com.
