How to Build Your Own Data Center & Why Every Startup Should Do It

Cliff Weitzman, co-founder and CEO of Speechify, tells Harry Stebbings that owning NVIDIA GPUs beats renting because renting costs 1.5x the purchase price yearly, so Speechify pays $100,000 per GPU to get Rubins and B300s early. He covers inference versus training workloads, liquid-cooling and insurance logistics, and NVIDIA's 25% buyback underwriting with Blackstone, BlackRock, Apollo and Goldman Sachs. Weitzman admits his biggest mistake was staying B2C as ElevenLabs leapfrogged Speechify through B2B APIs, and defends entering B2B against ElevenLabs and Bret Taylor's Sierra. He also argues founders should hire math olympiads over coders, details agent orchestration with Claude Code and Cursor, and explains how GPU clusters help him sequence genomes to cure his brother's orphan disease.

Inside Sequoia's Investment Committee | How the SpaceX & Citadel Deals Went Down | Julien Bek

Julien Bek, a Partner at Sequoia Capital, says Sequoia wins by hunting with conviction, not waiting for inbound calls, and shares founder-reading lessons from Don Valentine, Doug Leone, Pat Grady, Alfred Lin, and Shaun Maguire. He highlights Leone's 'worst reference' question, Lin's warning not to mistake an outlier operator for an outlier founder, and Maguire's ELO method for calibrating references. Bek also explains how asking 'why' five times exposed a fraudulent founder, how his read changes by country (French/German references get 1-2 extra points; Americans get subtracted), and why he missed Anton Osaka of Lovable. On AI, he argues agents become the new customer, AEO parallels SEO, and the next trillion-dollar company will be software masquerading as services. He tells how his mother invested in Revolut at a ~$200M valuation, now worth over $100B.
