Update on Meta’s Year of Efficiency

The situation

During the pandemic, people spent more time online and advertisers spent more on digital ads, and Meta hired rapidly to match. Then conditions changed. Apple’s App Tracking Transparency, introduced in 2021, reduced the precision of Meta’s ad targeting; TikTok competed fiercely for users’ time; and advertisers cut budgets as the economy slowed. In 2022 Meta’s revenue declined for the first time, while its spending on Reality Labs, the division building virtual and augmented reality, produced large losses. Its share price fell sharply.

In November 2022 Meta cut about 11,000 jobs. In February 2023, on an earnings call, Zuckerberg said 2023 would be a “Year of Efficiency.” In March he explained what that meant.

What the memo argues

The memo states two goals for the efficiency work: “(1) to make us a better technology company and (2) to improve our financial performance.” It then announces the cuts: Meta expected “to reduce our team size by around 10,000 people and to close around 5,000 additional open roles.”

It frames the change as a response to lasting conditions, not a temporary dip: Zuckerberg wrote that he believed “this new economic reality will continue for many years.”

The principles are organised under short headings. “Flatter is faster” described removing layers of management and asking many managers to return to individual work, with the aim that leaders would be closer to the work. “Leaner is better” argued that smaller teams can move faster and that the company had built too much overhead. “Keep technology the main thing” committed Meta to keeping engineering and technical work at the centre. “Invest in tools to get more efficient” pointed to AI and better internal tools as ways to do more with fewer people. And under a heading about in-person time, the memo cited internal analysis suggesting that engineers who joined Meta in person had, early in their tenure, “performed better on average than people who joined remotely.”

Throughout, the memo protects the long-term bets. Zuckerberg wrote that he believed Meta was “working on some of the most transformative technology our industry has ever seen,” and described AI as central to the company’s products and future.

The decision it carried

The memo announced a restructuring with several parts: about 10,000 job cuts, about 5,000 open roles closed, fewer layers of management, cancellation of lower-priority projects, and a hiring freeze while the changes were made, all while maintaining investment in AI and Reality Labs.

What happened

The restructurings were carried out in phases through the spring of 2023. Meta’s costs fell, its advertising business recovered, and its profits rose sharply. Investors responded strongly: Meta’s shares rose dramatically over 2023. The company used the period to accelerate its work on AI, releasing a series of large language models and building AI features across its apps.

The efficiency push did not end in 2023. Meta’s later results show it continued to manage headcount closely; its second-quarter 2026 report records severance costs connected with a headcount reduction in May 2026. The phrase “year of efficiency” was taken up by other technology companies conducting their own cuts.

How to read it as a product manager

The memo is a case study in reshaping an organisation, with lessons that apply at team level.

Layers slow decisions. Each management layer adds a step between the person doing the work and the person deciding about it. Counting layers, and asking whether each one adds judgement or only relays information, is a practical exercise for any product organisation.

Decide what to protect before deciding what to cut. Meta named AI and its core technology as priorities, then cancelled lower-priority work. Cutting evenly would have starved the priorities as much as everything else.

Efficiency is often a correction. Meta’s restructuring reversed a hiring surge that had assumed pandemic-era growth would continue. Product leaders can learn to plan headcount for a range of scenarios rather than the most optimistic one.

And the human cost is real. Two rounds of layoffs affected about 21,000 people, by the arithmetic of the two announcements. How such decisions are communicated and carried out shapes the trust of those who remain.

The decision, examined closely

What triggered it

Revenue had stalled and fallen while costs kept rising, and investors were openly questioning Meta’s spending on long-term projects. The November 2022 cuts had not fully reset the cost base. The memo was a second, deeper adjustment.

The constraints

Zuckerberg wanted to keep investing in AI and Reality Labs, which limited how much could be saved there. Meta also needed to keep enough engineers to compete with TikTok and to build AI products quickly. The cuts had to come from overhead, management layers and lower-priority projects.

What the author was optimising for

The memo optimises for speed and financial discipline while protecting the long-term technology bets. Flatter organisations and smaller teams were meant to make the company faster; lower costs were meant to restore profits and investor confidence, buying time for the bets to pay off.

Second-order effects

Meta’s turnaround gave other technology companies cover for their own cost-cutting and flattening, and the language of efficiency spread across the industry. Inside Meta, it changed expectations about management, with more managers expected to do individual technical work. It also coincided with the shift of investment toward AI, which became the centre of Meta’s strategy.

The counterfactual

Without the restructuring, Meta might have kept more people and projects but faced continued pressure from investors, possibly forcing cuts to the long-term bets themselves. It is also possible that market conditions would have improved anyway; some of Meta’s recovery came from a rebound in digital advertising generally.

What is contested

Critics point out that the efficiency programme corrected Meta’s own over-hiring, that layoffs carried a large human cost, and that the claim about in-person performance was based on internal analysis that was not published. Supporters argue that the restructuring was necessary and well executed, and that the results justified it. Both the financial recovery and the human cost are well documented.

Sources and limitations

Quotations were verified against Meta’s published memo. The figure of about 21,000 combined job cuts is the sum of the two announcements, not a figure Meta reported as a total. Details of Meta’s financial recovery are summarised from widely reported results rather than analysed in detail. The assessment of the restructuring is the author’s interpretation.
