ServiceNow CEO Bill McDermott told investors on April 22, 2026 the company would hold total headcount roughly flat through the start of 2027, even while absorbing three recent acquisitions: Moveworks, Veza, and Armis. His reasoning, reported by CNBC, was simple. Stop replacing people who leave, and let the software do the rest of the work.
"As you have attrition in the company, you don't have to backfill it... we can capture massive efficiencies to expand the free cash flow margin of the corporation," McDermott said.
ServiceNow is a public company with a market cap most Series B founders will never touch. But the decision he described, using AI productivity gains to absorb attrition instead of hiring to replace it, is showing up two funding stages earlier, in the go-to-market org charts of companies that just raised their B round. The venture data says this is no longer a fringe call. It is becoming the default one.
The math behind the decision
A survey of more than 150 B2B software go-to-market leaders found that companies with high AI adoption generate roughly $640,000 in net new annual recurring revenue per go-to-market employee, compared to $370,000 at low-adoption peers, according to ICONIQ Growth's "Building the Modern GTM Org" report. That gap compounds directly into headcount plans. At the $10 million to $25 million annual recurring revenue band, where most Series B companies sit, AI-forward companies run about 20 go-to-market employees versus 35 at less AI-forward peers generating identical revenue, a 43 percent headcount difference for the same output, per ICONIQ data covered by SaaStr. For a board evaluating a Series B budget, that is the difference between funding 20 salaries or 35 out of the same revenue base.
Carta's numbers show this isn't a forecast, it's already happened. Average Series B headcount fell from 53 employees to 45 between 2023 and 2025. Series D headcount fell even further, down 29 percent from its 2023 peak to 131 employees in 2025, according to Carta's "State of Startup Compensation: H2 2025" report. The same report found that across the entire venture-backed population Carta tracks, January 2026, historically the busiest hiring month of the year, produced only 26,030 new hires, the slowest January since 2018.
This isn't a cash problem
Founders staying lean in 2026 aren't doing it because money is scarce. More than 60 cents of every venture dollar invested in companies on Carta's platform in the first quarter of 2026 went to AI companies, the highest share ever recorded, and Series B primary pre-money valuations rose 17.2 percent year over year, according to Carta's "State of Private Markets: Q1 2026" report. Capital is available, and Series B companies are being priced as if growth is intact. Founders are simply choosing not to convert that capital into headcount at the rate they used to.
The pattern holds at scale, too. The median $100 million-plus B2B software company grew go-to-market headcount just 9 percent in 2026, down from 25 percent to 40 percent growth five years earlier, and median planned RevOps headcount growth for 2026 across surveyed companies sits at zero, per ICONIQ's "State of Go-to-Market 2026" report. The companies furthest along in scale are the ones pulling back hardest on headcount growth, not the ones under the most pressure to cut.
What to do this week
- Pull your go-to-market headcount against the ICONIQ benchmark: 20 FTEs at $10 million to $25 million ARR if you're running AI-forward, versus 35 if you're not. If you're closer to 35, find out why before your next board meeting.
- Before approving a new GTM hire, ask what a $270,000 gap in ARR per employee ($640,000 versus $370,000) buys you in tooling and automation instead, and whether that gap can close without the headcount.
- Adopt McDermott's rule on the next resignation: don't backfill by default. Make the team prove the role needs a person before you post the req.
Series B founders staying lean in 2026 aren't taking a risk. They're copying a decision a public company CEO already made in public, and the venture data says the flatter org chart is winning.
