Bio
VP of Marketing at vFairs. Writes the Behind Product Lines newsletter on building and marketing products in lockstep. Argues context engineering beats prompt engineering for marketing/GTM AI workflows, and treats positioning, messaging, and copy as three distinct layers that PMMs collapse at their peril.
Operating themes
- Context engineering over prompt engineering — reusable context documents as "battery packs" that power multiple AI workflows; ownership is required for them to stay live.
- Positioning ≠ Messaging ≠ Copy — three layers, three different decision rights; positioning is a business identity decision, not a marketing artifact.
