Building voice-AI infrastructure and scaling go-to-market globally with Carles Reina, GTM @ ElevenLabs & Angel Investor

Riding UnicornsCarles ReinaJun 4, 202547 min

Carles Reina's path from scaling Uber across Europe to becoming the first investor and eventual GTM lead at $3.3B AI unicorn ElevenLabs offers a masterclass in strategic career pivoting. He argues that angel investing can be a backdoor to executive roles when you lead with operational value rather than just capital, and reveals why voice AI finally succeeded where previous attempts like Alexa failed to sustain user engagement.

Key takeaways

  • Angel investors should lead with operational expertise before writing checks—helping with go-to-market strategy, contract negotiations, and pricing can open doors to executive opportunities.
  • Resource constraints force better decision-making: transitioning from billion-dollar budgets to seven-person teams teaches crucial lessons about profitable growth over growth at any cost.
  • Voice AI succeeded this time because modern models eliminated the human-in-the-loop requirements that made previous voice assistants clunky and limited.
  • The investor-to-employee path works when you become deeply embedded in the company's early challenges rather than remaining a passive check-writer.
  • Go-to-market execution often matters more than product perfection in the early stages of scaling AI startups globally.
