Overview
InsideScale provides go-to-market and sales development services for B2B SaaS and AI, acting as an on-the-ground partner that builds and runs embedded SDR teams and end-to-end GTM programs. It works by embedding into a client’s organization to execute campaigns, optimize the sales stack, and manage pipelines from outreach to qualification, including an audition-to-hire model for SDRs. It differentiates itself through hands-on, field-level partnership led by founder Lou Petrossi and a strong emphasis on GTM operations and talent-ready SDRs, with a portfolio of large clients. Its goal is to help high-growth technology companies scale quickly by delivering repeatable, data-informed GTM processes that generate qualified pipeline and revenue.
