The Company, The Founder, The Mission
Bottle Rocket Growth is a Chicago-based LinkedIn outbound agency and go-to-market consultancy. BRG was founded in 2024 by Mike Cubberly after more than a decade of building and scaling GTM teams across B2B SaaS, marketplaces, and services businesses.
The company serves early-stage and growth-stage B2B startups that need a real outbound motion, not a templated one. BRG runs signal-based LinkedIn campaigns on HeyReach using borrowed or client-owned sender profiles.
Why BRG Exists
Most B2B outbound in 2026 is broken. Teams buy a 10,000-row list from one provider, drop it into an automation tool, and send the same message to everyone. Acceptance rates below 20 percent. Meeting rates below 0.5 percent.
BRG was built around the opposite bet. Fewer prospects, better signals, and messaging that references what the prospect is actually experiencing. That is not a template. That is context.
The company operates with one core belief: outbound works when the prospect has a reason to listen today, not in general.
Company Origin
BRG launched in 2024 out of direct experience watching founders burn budget on outbound stacks that did not convert. Mike Cubberly had spent the prior decade at Verkada, Glencoco, Primer, and RevGenius, building and advising GTM teams across hypergrowth and pre-Series-A stages.
The pattern was consistent. Founders had strong product-market fit signals but no reliable pipeline motion. Hiring SDRs in-house was expensive, slow, and high-variance. Hiring a traditional outbound agency usually meant generic templated campaigns with little signal logic behind them.
BRG was built to close that gap: signal-based outbound delivered with agency efficiency, priced to work for startups under $10M ARR.
