Paid
Growth.

I run paid acquisition for funded startups. Embedded as a fractional growth lead, I own the channel end-to-end: build the mix, pressure-test the funnel, and find the unit economics that compound. The hands stay on the keyboard.

★ FOR FOUNDERS WHO
Want a senior operator,
not a ten-slide deck
and a handoff to a junior.

[ § 002B / Paid Media Audit ] $5K · 7–10 days · 2 slots / quarter

For SaaS that's
outgrown its agency.

Independent paid media audit by a senior operator — not a junior with a template. 40–60 page teardown of every campaign, 90-day roadmap with prioritized tests, Loom walkthrough, live readout. Fixed price. No retainer. If the audit doesn't surface 3× the cost in recoverable spend within 90 days, every dollar comes back.

[ § 003 / How It Works ] Engagement model

High agency.
Always shipping.

I don't wait for tickets. I read the data, find the leak, and ship the fix before the next standup — then bring you the receipts. The work happens whether or not you're online; the proactive write-ups land on Mondays.

Week 1—2

Diagnose

Audit accounts, attribution, creative library, and funnel math. You get a written read on what's working, what's broken, and what's worth funding.

Month 1—3

Rebuild

Restructure campaigns, ship new creative, fix tracking, plug in incrementality. Hands on the keyboard. No outsourcing to juniors.

Month 3+

Scale

Compound the channels that work, kill the ones that don't, and build the in-house function that replaces me. Transparent reporting, weekly.

[ § 005 / Let's talk ]

Make every
dollar compound.

Thirty minutes. Camera off if you want. Bring the dashboard you don't trust, the channel that won't scale, or the line item finance keeps asking about. If I'm not the right operator for the work, I'll tell you in the first ten minutes — and point you to who is.
