Verdict

Verdict

The $2.2B tells you…

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

How much capital arrived with it:$200M, led by Smash Capital in May 2026.

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

The $4.2B tells you…

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.
