Ignition is VC-backed and private, so its own revenue/ARR is NOT officially disclosed. First-party disclosed (Ignition press, 2025): 8,500+ customer firms, $3.1B in client revenue run through the platform, 3.7M payment transactions (91% auto-collected), $13B cumulative, and a $50M Series C led by JMI Equity in 2021. Founding story is first-party from Ignition 10-year blog. The payment-attach pivot is documented; the platform-disintermediation risk is our analysis. We never score you.
