Investment thesis
Growth-phase business — story-led; valuation sensitive to momentum.
Why interesting: Trading is scaling; acquirers paying for trajectory get disproportionate leverage.
Why risky: Price often leads fundamentals; dependency on founder often high.
Why now
Window steady · low confidence
Stable recent picture — watch for any upcoming trigger event.

  • secondary12+ year tenure: Director in role 13 years.
