Expense management heavyweight Ramp has raised a $750 million funding round, valuing the US fintech at $44 billion.

The investment was led by ICONIQ, GIC, and Ontario Teachers’ Pension Plan, with participation from numerous existing backers and several new shareholders, including Goldman Sachs Alternatives, Morgan Stanley Investment Management, and BroadLight Capital.

This latest round brings Ramp’s total equity financing to over $3 billion since its founding in 2019. The New York-based company raised $300 million just six months ago at a $32 billion valuation, and secured a $200 million Series E a year ago at a $16 billion valuation.

Ramp’s growth has been driven by an expanding product portfolio, including accounting agents, a new AI operating system, and spend infrastructure designed for early-stage companies.

Additionally, Ramp, which serves over 70,000 customers, including Visa, Uber, and Spotify, completed two acquisitions in March: travel platform Juno and Swedish payments platform Billhop.
