What I work on

The same four problems come up in every business I have run. I handle them myself, with AI doing the repetitive parts.

Offers and pricing
What you sell, to whom, at what price, and why someone says yes.
Funnels and CRM
Every lead captured, answered fast, and followed until it closes or says no.
AI operations
Assistants and automations that take repetitive work off the team.
Teams and SOPs
Clear owners, written processes, and numbers people can act on.

People I’ve helped

  • A teacher selling on Teachers Pay Teachers

    Moved her classroom resources from a marketplace listing to a store she owns. Built the Shopify storefront from her existing catalog and set up the ads behind it.

  • A retiring Wall Street COO starting an executive coaching practice

    Turning a Columbia coaching certification into a business: the offer, the pricing ladder, the intake assessment and the go-to-market plan.
