ElevenLabs hit $600M ARR in under three years by building voice AI that now powers customer support, sales, and interactive experiences, with plans to make voice agents indistinguishable from humans by end of 2025. The legal industry, a $1T market where software is only 4% of spend, is shifting from billable hours to AI-driven fixed pricing and in-house operations, with startups and law firms replacing junior associate work with agent orchestration. Both companies succeed by staying model-agnostic, embedding engineers across functions, and focusing on vertical workflows rather than competing directly with frontier model providers.
