There is not enough evidence to say senior engineers are leaving major technology companies in a broad wave for startups. Research does point to pressures that can affect retention, including return-to-office policies and concerns about job stability, while startup hiring and compensation remain uneven. The useful question is less whether an “exodus” is happening than what a specific engineer might gain or risk by making the move.
Is there really an exodus of senior engineers to startups?
The available evidence does not measure a general flow of senior engineers from large technology companies into startups. It is important to distinguish three different things: employees leaving a company, the destination they choose, and layoffs. Evidence of one does not prove the others.
A 2024 paper by David Van Dijcke, Florian Gunsilius, and Austin Wright analyzed 260 million matched resumes to study return-to-office policies at Microsoft, SpaceX, and Apple. The authors report reduced counterfactual tenure and a shift in the seniority distribution below senior levels, with stronger effects among longer-tenured and more senior employees. Their reported destination pattern points to larger direct competitors, not a demonstrated movement into startups. The paper is therefore evidence about retention at three companies, not proof of a startup-bound exodus. Read the paper.

The evidence reviewed also does not establish what share of departing senior engineers join startups, or why those who do choose them. Some may move to another large company, become independent, or leave employment. Treat “exodus” as a claim to test, not a measured trend.

What might push an engineer to consider leaving?
Workplace policy can matter, but the evidence is company-specific
The return-to-office study offers evidence that a workplace-policy change can affect retention and seniority patterns at the three firms it examined. It does not show that all large technology employers have the same outcomes, or that every affected employee objected to office requirements. For an individual, the relevant questions are the actual policy, how it is enforced, and its consequences for commute, relocation, family commitments, or visa status.
Stability has become a more prominent concern
Dice’s 2026 Tech Sentiment Report ranks job stability as the second most common reason to switch employers among surveyed US tech professionals, up from seventh in 2024. The report is based on a November–December 2025 survey of 1,159 professionals; it is not limited to senior engineers or people headed to startups. A startup is not automatically more secure: its funding, revenue, runway, and role priorities need to be assessed company by company. See Dice’s report.
Rank #2
Do not assume autonomy or impact is the reason
Smaller teams may offer broader ownership in some companies, but the available evidence does not establish that startups generally provide more autonomy, meaningful work, flexibility, or wealth. Treat these as offer-specific questions: who makes technical decisions, what systems the role owns, how much hands-on work is expected, and whether the project is central to the business.

Startup hiring is far below its 2022 peak, and conditions vary by sector. Carta reported that VC-backed companies on its platform made 26,030 hires in January 2026, 65% fewer than in January 2022. The same report says that, during 2025, most sectors had more hires than departures, but the balance differed:
- Hardware: 1.7 hires per departure.
- Medical devices, healthtech, and SaaS: 1.4 hires per departure in each sector.
- Gaming, biotech, and energy: weaker hire-to-departure ratios than the stronger sectors listed above.
These are Carta-platform headcount figures, not a count of senior-engineer openings across the entire startup market. January 2026 records may also be revised as companies enter data. They indicate that hiring is happening, not that a qualified candidate will find a role in a particular city or specialty. Review Carta’s startup compensation and hiring updates.
Geography changes the picture
State of European Tech reported that VC-backed tech job postings in Europe rose 25% in the first half of 2024 compared with the preceding six months. In the same report, 33% of surveyed founders said recruiting had eased, while 34% still found hiring difficult. Those figures describe a particular period and European market; they are not a current global hiring rate or a guarantee of demand for senior engineers. Read State of European Tech.
Is startup equity worth giving up Big Tech compensation?
There is no universal answer: a startup offer should be evaluated as cash plus a risky, terms-dependent equity grant, not as a headline total-compensation figure. Carta’s H1 2024 report found that average salary for senior individual contributors was the only job-level average that did not increase between May 2023 and April 2024. It also reported that average new-hire equity grants had fallen substantially from November 2022, though they had been roughly stable since September 2023. These data cover companies using Carta and are not a direct comparison with Big Tech offers. See Carta’s H1 2024 report.
Carta later reported rising AI/ML compensation and larger initial equity grants at smaller startups. That is a sector-specific finding, not a benchmark for all senior engineers. A strong package in one specialty should not be generalized to other roles. See Carta’s later compensation updates.
Best Value
Compare the offer on its actual terms
- Cash: Compare base salary and target bonus separately. Do not treat uncertain equity value as cash you will receive.
- Equity: Ask about the instrument, number of shares or options, vesting schedule, dilution, exercise window, and what would need to happen for liquidity. A grant cannot be valued from its share count alone; the sources do not establish a value for any particular offer.
- Stability: Ask about cash runway, financing plans, revenue or other traction, hiring intentions, and whether the role supports a core product or a discretionary initiative. These are diligence questions, not guarantees.
- Scope: Clarify decision-making authority, technical ownership, team size, and the expected balance of hands-on work and coordination.
- Workplace and location: Confirm remote, hybrid, or office expectations, plus relocation or visa implications where relevant.
- Stage and sector: Use hiring trends as context only. Sector averages do not predict a particular company’s prospects or an individual role’s availability.
How to decide whether to make the move
- Identify the reason you want to leave. Separate what is pushing you away—such as a workplace policy or perceived instability—from what is pulling you toward this particular startup.
- Check whether the startup’s needs match your role. Ask what the team must deliver, which systems you would own, and how the company will judge success. A broad title is not the same as real technical authority.
- Test the company’s stability assumptions. Ask leadership about runway, funding plans, business traction, and hiring priorities. Treat answers as inputs to a risk assessment, not as a promise that the job is secure.
- Model compensation without assuming an equity payout. Compare guaranteed cash and benefits first; then assess the grant using its terms and realistic liquidity scenarios.
- Verify the working arrangement. Get expectations on office attendance, location, travel, and team practices clear before accepting.
- Compare alternatives honestly. The relevant choice may be this startup versus staying, joining another large employer, consulting, or taking time away—not startups as a single category versus Big Tech as a single category.
What the evidence can—and cannot—tell you
Current evidence supports a more cautious conclusion than the phrase “Big Tech exodus” suggests. A three-company study links return-to-office policies with retention and seniority shifts, but reports destinations among larger direct competitors. Survey evidence shows stability matters to tech workers, while startup hiring and compensation data point to a market that is active but cooler than the boom and uneven across sectors. None of these sources tracks a representative share of senior engineers leaving major technology firms specifically for startups or establishes their stated reasons for doing so.
That gap matters for career decisions: broad market claims cannot tell you whether an individual startup is a better fit. Compare the specific work, workplace expectations, financing risk, cash, and equity terms in the offer in front of you.
