Hebbia tripled new ARR in its best quarter without disclosing revenue; UBS put it on an IPO watch list
Hebbia's best-ever quarter came with three ratios and one dollar figure, and the dollar figure is a tracker's mark, not the company's. UBS just named it to an IPO watch list priced off a $7.2 billion market.

George Sivulka, Hebbia's$670.7M — Hebbia, private, latest valuation $670.7M chief executive, posted on October 21 that Q3 2026 was the biggest quarter in the company's history: new ARR tripled quarter over quarter, daily active users grew 5x, and gross revenue retention exceeded 95% 1. Read those three closely and they are not the same kind of number. The first is a bookings flow, the second a usage count, the third a retention rate. Only the first is money at all, and none arrives with a dollar sign attached.
The only dollar on the table belongs to a tracker
Hebbia, the AI platform that automates analyst work across deal documents on Wall Street, publishes no revenue line. The only public dollar figure is a third-party mark: the ARR Club tracker logged Hebbia at $50 million of ARR as of September 2026 1.
The same tracker tagged the Q3 announcement with a growth rate of +127% 1, which is not a triple. If the stock of ARR is $50 million and the gross new bookings added in the quarter tripled off an unpublished base, a reader cannot tell whether the quarter added $5 million or $15 million; nothing outside the company prices it 1. The tracker's own +127% tag suggests the triple is measured on a different basis than ARR, likely gross bookings rather than net, but that basis is disclosed nowhere 1.
What the usage numbers actually say
The usage detail is arguably the stronger signal, and Sivulka's own post said the usage growth excited him most 13. Daily actives up 5x with retention above 95% means adoption is widening and sticking 13. If that pattern continues, it is the footprint junior-analyst-seat substitution leaves before it reaches a vendor's reported revenue 13. One market account added the margin mechanism: Hebbia carries essentially no capital cost of its own, so any fall in model token prices flows straight to its margin 4.
Then the market arrived
In a note published October 25-26, UBS listed 100 private AI and software companies it is watching ahead of potential IPOs, Hebbia among them, alongside Databricks$216.58B — Databricks, private, latest valuation $216.58B, Canva, Harvey$15.5B — Harvey, private, latest valuation $15.5B and Perplexity$20B — Perplexity, private, latest valuation $20B 2.
UBS put Hebbia in a market box it shares with Harvey, its closest comparable: agentic AI for finance plus legal AI software, a core addressable market of about $7.2 billion in 2026 growing to $46.7 billion by 2034 2. Hebbia also opened Q4 by signing five new banks in a single week, its largest customer base remaining financial services 1.
Harvey is the benchmark, and it does not help
Here is the problem for a public investor trying to size the IPO candidate. UBS places Hebbia and Harvey in the same $7.2 billion box 2, so Harvey's disclosed figures would be the only yardstick to price Hebbia against.
But UBS's note describes Harvey's traction qualitatively: acquisitions, deployment across the AmLaw 10 firms, no ARR dollar disclosed either 2. The box's two occupants have published one dollar figure between them, and that one is a tracker's mark. Anyone anchoring a valuation on the $50 million is pricing a September snapshot against a quarter the company itself says was its best ever, which likely makes the mark stale in the direction that matters 2.
What to watch next
The operating compounding looks real; the disclosed dollars are not. Three things settle it. First, whether the $50 million ARR stock gets an updated mark, because that is the number the triple attaches to.
Second, whether the five-bank week becomes a Q4 logo list, which would show financial services demand accelerating rather than spiking. Third, whether retention holds above 95% as daily usage compounds, the signature of substitution rather than experimentation. If the dollars stay hidden, buyers of any future round price the story, and public investors marking seat-priced data and analyst vendors get the news last, after the seats have already left.
As of late October 2026, Hebbia's tracked ARR is the smallest figure on UBS's IPO watch list
