Protect AI's tuck-in acquisition bet ended in a $500M-plus Palo Alto exit (interview)

Protect AI secured the machine-learning models and infrastructure enterprises were deploying at scale.

$108.5M from Acrew Capital, Samsung, StepStone Group, Salesforce Ventures and others — mostly from outside Seattle, raised without a road show.

Ian Swanson sold Sometrics to American Express and DataScience to Oracle, then led worldwide AI go-to-market at AWS; seeing thousands of companies put AI into production without anyone securing it, he started Protect AI in 2021 with Badar Ahmed and Daryan Dehghanpisheh.

The first idea, adversarial machine learning, found little traction; the founders re-aimed at enterprises' ML security blind spots. From 2023 it bought Huntr, then Rebuff, Laiyer AI and SydeLabs — four tuck-ins some investors questioned while Protect AI's capital base was still small.

Palo Alto Networks agreed to buy Protect AI; sources familiar with the deal told GeekWire it was valued north of $500 million, with closing expected later in 2025.

AI adoption outran AI security, and no incumbent was diving deep on the new risks — a white space a serial founder could claim.

Tuck-in acquisitions assembled threat research and capabilities faster than hiring, even on a modest capital base.

Enterprise buyers preferred one complete platform over a market map of unknown point products in a segment they didn't understand.

A team from AWS and two exits brought AI depth most security companies lacked, making the platform story credible.

In a market nobody can define yet, completeness sells: four cheap acquisitions made Protect AI the one-stop answer before competitors finished their market maps.

As of May 9, 2025, the Palo Alto Networks deal was expected to close later in the year, with Protect AI planning to keep growing out of its downtown Seattle office inside the buyer.
