Kleiner Perkins
Check: $1M-$50M+
Leads Kleiner Perkins' enterprise practice. Previously at Social Capital where he led the Slack and Figma investments — two of the most product-obsessed enterprise companies ever built. Strong product-first culture: believes the best enterprise companies feel like consumer products. The enterprise should be delightful, not just functional. Mamoon's core insight: enterprise software was historically sold top-down (CIO buys for the company), but the best modern enterprise companies grow bottom-up (individual users love the product, it spreads through the organization, and eventually the company buys an enterprise license). This 'product-led growth' (PLG) pattern defined Slack, Figma, Notion, and many of the best enterprise companies of the last decade. Now at Kleiner Perkins, Mamoon applies this same lens to AI-native enterprise products — looking for AI tools that are so delightful and useful that they spread organically within organizations.
