Tom Regan is the founder of Artemis GTM, a GTM engineering consulting firm that builds and runs outbound and inbound GTM systems for seed to Series C B2B startups, hands-on, inside the client's own stack. He was a founding SDR leader at Apollo.io, where he helped scale the company from $800K to $50M ARR and personally closed $5.27M in ARR. He now advises teams on implementing Amplemarket, drawing on systems built across Artemis GTM's hands-on B2B SaaS audits.
