The New Math of Company Building with Garry Tan

The 10-person, $100M startup is here. Are you building it?

At our AI List event a few days ago, I did a fireside chat with Y Combinator CEO Garry Tan to discuss what’s happening on the ground with AI startups.

According to Garry, here’s what matters for founders:

The New Math of Company Building
Fifteen years ago, if you wanted to scale a meaningful company, you needed to raise $100 million and hire 500 people to reach $20-30 million in annual revenue. That was the playbook. Today, something remarkable is happening. AI-native startups are reaching $50M ARR with teams of 15-20 people. In the next 2-3 years, as models become 2-10x smarter, we’re going to see companies go from zero to $100M ARR in a single year with just 10 people. The economics for building and scaling a startup have fundamentally changed.

Three Principles for AI Founders

  • 1. Go after market expansion, not displacement. The $5T IT budget is crowded. The $30T knowledge worker spend, and the $50T+ physical worlds spend are wide open. Build in fragmented markets, attack weak incumbents, and create experiences that are 10x better than what humans alone could deliver.
  • 2. Build superintelligence into your core. Stop thinking “AI assistant.” Start building systems that do what humans can’t. For example, voice AI startup Giga can resolve DoorDash’s three-party delivery disputes (between a Dasher/driver, restaurant, and customer) in 30 seconds versus 10+ minutes of manual work between humans. That’s superhuman capability. Automating existing workflows isn’t enough.
  • 3. Master meta-prompting to 10X yourself. Founders need to effectively collaborate with AI. Garry iterates through 20+ versions of his prompts, training them to match his voice and needs. Each prompt becomes “better than the best associate you could ever hire.” This is the skill that separates 10-person companies from 500-person ones.

What This Means for Founders

  • 1. Paint a compelling vision in a few minutes (if you can’t, you probably can’t recruit or sell either)
  • 2. Prioritize building 10x better products over growth hacks
  • 3. Implement AI into their core systems from day one
  • 4. Target market expansion

Success as a founder isn’t avoiding failure. Your mission is to avoid predictable mistakes while building something that scales to billions. That’s where experienced investors add value – helping you sidestep landmines and supporting your vision.
