Last updated: July 21, 2026

Bull (15%)+126%

Tessian retains Proofpoint backing and captures market share; exit multiple expands to 10x, implying $283M exit value.

Base (45%)+81%

Revenue grows modestly; exit multiple converges to 8x, yielding $226M exit value, above total funding but below earlier rounds.

Bear (40%)-100%

Exit value falls below $182M total funding; preference stack wipes out common equity entirely.

Funding Intensity

146%

Dilution Risk

low

No further dilutive raises expected given the recent acquisition and parent funding.

Secondary Liquidity

none

No secondary market exists; equity is tied to Proofpoint, which is privately held by Thoma Bravo.
