Startup investors poured more than a dozen rounds over $100 million this week, with Ramp closing a $750 million deal that values the New York spend‑management platform at $44 billion. The round, led by Iconiq, GIC and Ontario Teachers’ Pension Plan, underscores a surge in enterprise‑software funding.

Three $500 million rounds followed, all in high‑growth sectors. Impulse Space (space tech), Supabase (AI developer tools) and Flourish (foundational AI) each raised $500 million, pushing valuations to $15.5 billion for Helion’s fusion ambitions and $10.5 billion for Supabase. Investors see potential in niche tech that can scale.

Other notable deals included Helion’s $465 million Series G, bringing total funding to $1.5 billion, and NewLimit’s $435 million Series C for epigenetic longevity drugs. These sums highlight a willingness to back breakthrough science.

The wave signals that venture capital remains aggressive toward transformative tech, rewarding companies that promise disruptive scalability and high valuations.
