Bio
Leah Tharin's core framework treats AI not as a feature to bolt onto existing products but as a structural disruption that invalidates the assumptions companies built their organizations around. Her central thesis is that AI simultaneously makes it cheaper to build comparable software, makes acquisition channels less differentiating, and forces budget reallocation from sales and marketing into product. This triple pressure means established scaleups cannot respond with incremental optimization. They must operate like startups again: small teams, rapid experimentation, willingness to throw away what does not retain users.
Operating themes
- Operating thesis: AI is collapsing the efficiency advantages that scaled SaaS companies built over a decade, forcing every scaleup back into startup mode where cross-functional growth teams, not siloed departments, must re-prove product-market fit from retention up.
- Ai Buyer Psychology
- Ai Product Strategy
- Product Led Growth Strategy
- Ai Product Positioning
