Meta’s willing to pay $2M for top AI talent. A Series A startup might offer $150K plus 0.5%
equity. Which is better? The answer depends on your risk tolerance, career stage, and how
much you believe startup equity is actually worth. Here’s the real math.

The Base Salary Gap

Let’s start with the numbers that hit your bank account every two weeks. Startups hire
30% faster than big tech (12 vs 42 days average), but they offer about 11% lower base
salaries. The average tech salary across all companies is $112,521 in 2025, but this
varies dramatically by company stage.

The gap is most pronounced at entry level. A new grad at Google (L3) gets $181K total comp,
while the same engineer at a seed-stage startup might get $100K base plus equity worth…
well, that’s the question.

Big Tech Compensation: The Known Quantity

Big tech compensation is predictable and liquid. Your RSUs vest quarterly, you know exactly
what they’re worth (today, at least), and you can sell them immediately. Here’s what
senior engineers earn at major tech companies:

Startup Compensation: The Equity Gamble

Startups compensate for lower base salary with equity—a percentage ownership in the company.
The question is: what’s that equity actually worth? The answer is almost always “less than
you think” but occasionally “much more than you imagined.”

How Startup Equity Works

At a seed-stage startup valued at $10M, 0.5% equity equals $50,000 in “paper value.” But:

• It vests over 4 years with a 1-year cliff
• Future funding rounds dilute you by 15-25% each round
• You can’t sell it until an exit (IPO or acquisition)
• Most startups fail or never reach meaningful exits
• Exit valuations often favor investors over common shareholders

Your 0.5% became 0.27% through dilution. If the company exits at $1B, that’s $2.7M before
taxes—not bad! But if it exits at $100M (a “successful” acquisition for most startups),
that’s $270K before taxes, spread over 4-6 years of your career.

The Real Math: 4-Year Comparison

Let’s compare a senior engineer’s total earnings over 4 years at different company types:

Over 4 years, a Google L5 takes home about $1.46M in guaranteed, liquid compensation. A
seed-stage startup employee takes home $480K in cash plus equity that’s probably worth $0
but could theoretically be worth millions.

The Opportunity Cost

The $980K difference ($1.46M – $480K) is your opportunity cost for joining the startup.
For that equity to be “worth it,” it needs to eventually be worth more than $980K after
taxes and dilution. Run the numbers:

• You start with 1.0% equity at a $5M seed valuation
• After dilution, you end with ~0.5% at exit
• To net $980K after 35% capital gains tax, you need $1.5M pre-tax
• 0.5% = $1.5M requires a $300M exit valuation

Your seed-stage startup needs to exit at $300M+ just to break even with the FAANG offer.
What percentage of seed startups reach $300M exits? Less than 1%.

When Startups Actually Make Sense

Despite the math, there are legitimate reasons to choose startups:

The Generational Shift in Preferences

Interestingly, younger engineers are increasingly choosing equity over cash. According to
a 2024 AngelList report, 63% of employees under 30 said they’d consider a lower salary
for a higher equity stake. This was just 41% in 2021.

This shift reflects a few things: big tech layoffs have reduced perceived job security,
AI/LLM startups have created genuinely exciting opportunities, and the “million-dollar
FAANG job” is no longer as guaranteed as it seemed.

AI Talent: A Special Case

AI/ML engineers are seeing the fastest salary growth at startups. Among startups valued
between $1M-$10M, the median salary for AI/ML engineers is up 9.1% year-over-year, with
90th percentile salaries up 9.5%.

The competition for AI talent has created a market where even early-stage startups pay
$140K-$180K base, and big tech pays $200K-$300K base for the same roles. OpenAI and
Anthropic reportedly pay $300K+ even for non-senior roles.

Making Your Decision: A Framework

The Bottom Line

From a pure expected-value perspective, big tech wins. The guaranteed $400K-$500K/year
total comp for senior engineers beats the lottery-ticket economics of startup equity
in most scenarios.

But careers aren’t just about maximizing lifetime earnings. Startups offer faster learning,
more ownership, and occasionally life-changing outcomes. The key is going in with realistic
expectations: your startup equity is probably worth $0, and that’s okay if you’re getting
other things (experience, learning, autonomy) in return.

The worst outcome is taking a 40% pay cut for startup equity while telling yourself it’ll
definitely be worth millions. Value the equity at $0, decide if the job is still worth
it at that salary, and treat any eventual payout as a bonus.
