- Six months later ElevenLabs hit one million users and invited Luke to lead growth, proving timing and belief can change fast.
From YC To Covid Testing To $30M ARR
- Luke co-founded Fella, pivoted through COVID testing and digital CBT, then built a GLP-1 clinic that reached $300k revenue.
- He left early due to impatience while the business later scaled to $30M ARR under his co-founder Richie.
