Growth for SaaS

I grow products end to end: acquisition, funnels, email, offers and the AI systems that tie it all together. Ads are just the part you can see.

  • Now: Growth Manager @ The Feed Media
  • Focus: growing products end to end: SaaS, AI, media, ecommerce & creator brands
  • Edge: full-funnel execution + AI systems I build myself

↑ yes, that's me on camera. I do that.

01 I build the systems, not just the campaigns

Most marketers stop at the campaign. I ship the AI agents and automations that run growth itself, so a lean team moves like a big one.
Call it growth engineering, or vibe marketing. Either way, I build it myself.

Oh, and this website? Also Claude Code. Designed, built and maintained by me, prompt by prompt.

Beat the incumbent agency head-to-head and won the account.

A Media Operator

Not a media buyer.
I run the whole growth function.

Paid ads are the part you can see. What I actually run is the whole machine that turns a product into revenue, and the systems that keep it compounding.

Positioning & GTM the message, before the spend
Full-funnel acquisition paid + creative, bought on CAC
Lifecycle & retention email that activates and keeps
Analytics & North-Star the metric that actually matters
Experimentation tests with a real hypothesis
Growth engineering AI systems that compound it

How I'd grow your product

Drop me into a SaaS, a newsletter or a launch from zero and this is the loop I run. Each stage hands off to the next, then feeds back into it.

  1. 01 Find the real offer Who actually buys, what makes them switch, and the one promise worth leading with.
  2. 02 Buy attention that converts Creative that sounds like the customer, judged on cost-per-customer, not clicks.
  3. 03 Catch them on landing Pages and lead magnets that earn the email, with qualification baked in from day one.
  4. 04 Turn signups into fans Onboarding and lifecycle email that activate people fast, the part most teams skip.
  5. 05 Make the money work Offers and funnels tied to LTV, so spend chases revenue, not vanity metrics.
  6. 06 Make it compound Tests, dashboards and the AI tools I build, so next month beats this one.
