GrowthMarketer

GrowthMarketer provides growth engineering as a service for B2B SaaS and DTC brands.

Growth marketing has changed. Third-party cookies are gone, pixel-based tracking overcounts by 30 to 50%, and AI collapsed the cost of campaign builds, reporting, and creative iteration from weeks to hours. The agencies still billing for 10-person pods are selling a structure built for 2019.

Growth engineering is what replaces it. One senior operator in your ad accounts daily, paired with AI workflows and proprietary tooling, running the full stack: Meta, Google, LinkedIn, TikTok, and programmatic media buying; server-side attribution so reporting matches your P&L; creative direction and high-tempo testing; landing page and funnel optimization. No layers between strategy and execution. You get the output of a team at the cost of a hire.

The service was built by Robbie Jack, who bootstrapped TrueCoach to 20,000 customers and an 8-figure exit using the same playbook. He hired agencies along the way, including good ones, and watched the same problems repeat: inflated metrics, slow creative cycles, layers between the founder and the work. GrowthMarketer is the service he wished existed back then. 50+ brands scaled since, $50M+ in managed ad spend.

Pricing: $10K/month base plus profit share on marketing-attributed revenue. Month-to-month, no contracts, 30 days notice. You own the ad accounts, tracking, dashboards, and creative frameworks. Walk away and keep everything.

Good fit: post-PMF brands with traction, a team that can execute on creative briefs, and leadership that values async delivery over weekly status calls.

Not a fit: pre-revenue, agencies of record, or buyers optimizing for the cheapest option.
