Treetop Growth Strategy

Based in Chicago, Illinois, Treetop Growth Strategy is a small team (1-10 people) working with B2B companies that lack a senior marketing leader, offering a fractional CMO model built around an in-house AI system rather than standard agency execution. Founded in 2016, the agency positions itself as an alternative to hiring a full-time CMO or engaging a traditional retainer agency, aiming to install both leadership and a repeatable revenue system rather than delivering slide decks and status calls. The operator behind the agency, Bill Col, has a background that includes serving as a CMO at a company acquired by HelloFresh and as VP of Sales & Marketing at a company acquired by NASM, along with experience running a HubSpot partner agency. The declared services include Search Engine Optimization, Pay Per Click, Content Marketing, Email Marketing, and Sales Outsourcing, delivered through what the agency calls the Revenue Engine Method, a sequence of Memory, Intelligence, and Motion. In practice this means building persistent competitor, ICP, and revenue memory into a system that retrains on client data monthly, rather than relying on ad-hoc briefs for each campaign. The AI components are described as in-house products (referred to as Billy and Fitagentic) that are also used internally, and prospective clients can trial an "AI CMO" tool before booking a strategy call. Engagements are run on a custom-scope retainer with month-to-month flexibility, and client work is kept under NDA by default.
