Core Services: Fractional CMO Leadership - Senior marketing executives who provide strategic direction, channel prioritization, messaging development, and team oversight without full-time overhead. Two models: $5K/month for strategic advisory (client team executes), or $10K/month for full execution (we handle all marketing work).
Full-Stack Marketing Execution - Comprehensive channel management including SEO, paid advertising (Google Ads, LinkedIn, Meta, Spotify), PR, content marketing, email marketing, growth hacking, podcast marketing, and Generative Engine Optimization (GEO) for AI search visibility.

What Makes Us Different: Unlike traditional agencies, we integrate directly into client workflows via Slack and operate as embedded team members. Our consultants average 15+ years of experience each. We limit client load to maintain quality and genuine partnership.
Clients typically save ~$200K in Year 1 vs hiring full-time marketing leadership.

Processes and approach
How do you gather and validate client requirements?
We start with a discovery call to understand growth stage, current challenges, and revenue goals. Then we audit existing channels, review analytics, and conduct stakeholder interviews. Requirements are validated through a documented strategy deck that clients review and approve before execution begins.
How do you ensure alignment with client goals and business strategy?
Weekly strategy calls keep us locked to revenue targets and business priorities. We tie every marketing initiative directly to measurable outcomes (pipeline, conversions, revenue). Our fractional CMOs attend leadership meetings and stay embedded in Slack to course-correct in real-time as strategy evolves.
How do you keep clients and stakeholders updated on project progress?
We provide weekly performance dashboards with clear metrics (traffic, leads, conversions, spend). Monthly reports include channel performance, tests run, wins/losses, and next steps. Clients have 24/7 Slack access for real-time updates, and we're transparent about what's working and what's not.
How frequently do you hold check-in meetings or status updates?
Weekly strategic calls are standard for all fractional CMO clients. For full-execution engagements ($10K/month tier), we also attend internal standups and ad-hoc meetings as needed. Frequency increases during launches, campaigns, or rapid experimentation phases.
