Chief Outsiders

Chief Outsiders supplies fractional CMOs, CSOs and implementation teams to mid-sized and private equity-backed companies, supported by its GrowthGears OS platform.

Chief Outsiders describes itself as an Executives-as-a-Service firm that helps CEOs identify and deploy fractional marketing and sales executives. Its pages say it founded the firm to give mid-market and PE-backed companies growth leadership usually reserved for the Fortune 500, on demand and without the full-time cost. Its contact page states that the initial consultation is available only for companies with revenues over $5 million.

The firm offers fractional and interim CMOs and CSOs, and its about page also names CROs. Team Outsiders provides specialized marketing and sales professionals who add implementation capacity. GrowthGears OS is its AI-enabled platform that brings together the Growth Gears methodology, a framework of insight, strategy and execution. Its sales consulting page states that it embeds fractional CSOs or CROs in a business to lead execution.

Engagement runs in four steps: an initial consult with a Managing Partner, a fractional match, a growth plan with a customized statement of work, and a quick start in days. Its contact page states that all agreements allow clients to cancel with 30 days' notice, and its about page states a full refund of fees if a client is not convinced within 30 days.

Its site states that it has served more than 2,000 clients and lists industries including manufacturing, healthcare, consumer products, hospitality, SaaS and financial services.

Its about page states that the firm was founded in 2009 by Art Saxby.

Who it fitsOpinion, not a ranking

From its own pages, Chief Outsiders is aimed at CEOs of mid-market and PE-backed companies, and one page notes the offer is available only to companies above a stated revenue floor. The industries named include private equity and portfolio companies, manufacturing, distribution, healthcare, consumer products and home services. The problems it takes on are stalled sales performance, an unpredictable pipeline, missing sales leadership, and CEOs who lack the talent or time to drive a growth strategy. A client engages by having a Managing Partner assess its challenges, choosing a fractional CMO or CSO, and agreeing a statement of work; the executive starts in days, agreements can be cancelled on notice, and a full refund is offered if the client is not convinced early on. Team Outsiders implementation staff are also offered to fill gaps on a client's team.
