What an investor paid for newly issued shares — a primary round, priced post-money.

How much capital arrived with it:$450M, led by Snowpoint Ventures in May 2026.

A dated print: it moves only when a newer round is announced.

At least one valuation basis is undisclosed, so the two numbers stay side by side, each with its own chip, and no ratio is scored. Both are private: there is no public quote and no Canborsa market on either name.
