Workweek

Mike Madarasz

Ran paid growth across 6 B2B brands and got all of them green at once.

A B2B media startup running 6 creator-led newsletters across fintech, health-tech, HR and marketing. My largest, most complex account. Six brands, six audiences, six CAC targets, one me.

The brief

Workweek is a B2B media startup running a portfolio of creator-led newsletters, Marketing Millennials, Go-to-Millions, Fintech Takes, Hospitalogy, I Hate It Here and Fintech Takes Banking. It's my largest, most complex account: 6 brands, each with its own audience and CAC target.

What I did

  • GM + primary contact from onboarding; built per-brand OneSheets, managed 5+ ad accounts and brand kits.
  • Multi-newsletter concept ideation at scale; set a per-newsletter DCT convention to prevent mix-ups.
  • Scaled a UGC podcast concept into a cross-account winner; "This Is For You" hit target on 5 of 6 brands.
  • Built reporting off the client's own Hex/N8N stack, plus a weekly per-newsletter analysis digest.
