A $300 Million Startup Exit. How Much Do Founders Actually Get?

What we know about Firebolt

On January 26, 2022, Firebolt announced a $100 million Series C financing led by Alkeon Capital.

The investment valued the company at $1.4 billion and brought its total announced funding to $269 million.

On November 5, 2026, WireIsrael reported that MongoDB was in advanced talks to acquire Firebolt for an estimated $250 million to $300 million. The publication said negotiations had not been finalized.

The reported negotiations do not establish that an acquisition agreement has been signed or that a transaction has been completed.

The difference between the former valuation and the reported acquisition price is striking.

But there's something more important than the decline itself.

A $1.4 billion valuation based on the price investors paid for preferred shares never meant that all common shares were worth the same price per share.

Preferred stock often carries downside protections that founders' and employees' common shares do not.

And when the company sells for less than expected, those protections can become extremely valuable.

The liquidation waterfall: Who gets paid first?

When a venture-backed startup is acquired, the proceeds aren't necessarily distributed according to ownership percentages.

Investors typically hold preferred stock with liquidation preferences.

A standard 1x liquidation preference generally allows an investor to recover the amount invested before common shareholders receive proceeds, subject to the actual financing documents and available sale proceeds.

Two structures are particularly important.

Non-participating preferred stock: Investors generally choose between taking their liquidation preference and converting into common stock to receive their proportional ownership share.

Participating preferred stock: Investors generally receive their liquidation preference first and then participate in the remaining proceeds, potentially subject to a cap.

The second structure can leave much less for founders and employees.

However, it is not the typical structure in recent US venture financings. According to Cooley's Q4 2025 Venture Financing Report, 98% of the deals in its dataset had a 1x liquidation preference, and 96% had non-participating preferred stock.

Let's calculate the difference.

One $300 million exit. Three different outcomes.

For illustration, assume a hypothetical startup with these characteristics:

• Investors contributed $269 million.
• Investors own 70% on an as-converted basis.
• Founders and employees collectively own 30%.
• Preferred investors have an aggregate 1x liquidation preference of $269 million.
• All preferred shares have equal priority.
• There are no debts, transaction expenses, escrows, or other deductions.
• The full $300 million purchase price is available for equity distribution.

This simplified model does not represent Firebolt's actual capitalization table.

Scenario 1: Proportional ownership

Imagine all investors hold common stock, or all preferred investors convert into common stock.

The $300 million would be divided according to ownership.

Investors receive:

$300M × 70% = $210M

Founders and employees receive:

$300M × 30% = $90M

Founders and employees receive $90 million.

That's the result founders might expect if they look only at ownership percentages.

But preferred investors don't necessarily have to accept that outcome.

Scenario 2: 1x non-participating preferred

Now assume investors hold standard 1x non-participating preferred stock.

At a $300 million sale price, they have two alternatives:

• Convert into common stock and receive $210 million.
• Exercise their liquidation preference and receive $269 million.

Naturally, they choose the preference.

That leaves:

$300M - $269M = $31M

Founders and employees receive $31 million.

Same startup. Same buyer. Same purchase price.

But the founders' and employees' collective proceeds have fallen from $90 million to $31 million.

Scenario 3: 1x uncapped participating preferred

Now consider a less-common arrangement: 1x uncapped participating preferred stock.

The investors first recover $269 million.

They then participate in the remaining $31 million according to their 70% ownership.

Their additional participation is:

$31M × 70% = $21.7M

Total investor proceeds:

$269M + $21.7M = $290.7M

The remaining proceeds go to common shareholders:

$31M × 30% = $9.3M

Founders and employees receive $9.3 million.

This example assumes uncapped participation. A capped participating structure could produce a different result.

The comparison

The same $300 million acquisition can produce dramatically different outcomes depending on the rights attached to the shares.

And these are collective amounts. An individual founder receives only their portion of the proceeds allocated to the relevant shareholders.

The $384 million number founders should understand

Here's where the analysis gets more interesting.

In our hypothetical example, investors own 70% of the company and have a $269 million liquidation preference.

At what acquisition price would they prefer to convert into common stock?

We divide their liquidation preference by their ownership percentage:

$269M ÷ 70% = $384.3M

That's the approximate break-even acquisition price for the investors.

At a $300 million exit, they prefer the $269 million liquidation preference over the $210 million they'd receive through conversion.

But at a $400 million exit, converting into common stock gives them:

$400M × 70% = $280M

That's $11 million more than their preference.

So the investors' optimal decision changes at approximately $384 million.

Below that threshold, they generally prefer their liquidation preference. Above it, they generally prefer to convert.

This is why founders should understand not only their ownership percentages but also the acquisition prices at which their investors' economic incentives change.

In a real capitalization table, different financing rounds can carry different preferences, seniority, and conversion thresholds.

There may be several inflection points, not just one.

What happens if the company sells for $250 million?

Under our hypothetical assumptions, investors have $269 million in liquidation preferences, but only $250 million is available for distribution.

If all preferred investors exercise their preferences and have equal priority, they receive the available $250 million.

Common shareholders receive zero.

This doesn't mean every startup that sells for less than its cumulative funding leaves founders empty-handed.

The outcome depends on outstanding preferred investments, conversion rights, seniority, the transaction's distributable proceeds, and other contractual arrangements.

But it illustrates something founders should understand before raising capital:

The amount you raise can affect what you receive at exit, even years after that financing closes.

The real-world twist: Founders can receive nothing for their shares and still get paid

A liquidation waterfall doesn't always capture every dollar paid in an acquisition.

Imagine a company receiving a $250 million offer when preferred shareholders have $269 million in liquidation preferences.

Common shareholders would receive nothing under the simplified waterfall.

But the buyer still needs the founders, CTO, and key engineers to stay after the acquisition.

Those people may have little financial incentive to remain if their existing options and shares have no value.

That is where management carve-outs and retention packages can enter the negotiation.

For example, a buyer or the existing company might negotiate a $10 million incentive arrangement for selected executives and employees.

There are two very different ways to structure it.

Option A: The $10 million comes out of the acquisition proceeds.

If the original purchase consideration is $250 million, allocating $10 million to a carve-out can leave $240 million available for shareholders.

That reduces what investors would otherwise receive.

Option B: The buyer funds a separate $10 million retention program.

The buyer might provide additional compensation for employees who remain after closing, potentially subject to future service conditions.

That compensation may be separate from the purchase consideration.

The distinction matters for the buyer, investors, employees, and tax authorities.

It also creates sensitive negotiations over who receives the payments, who bears the cost, what approvals are necessary, and whether management has conflicts of interest.

Management carve-outs are not simply a way to bypass preferred shareholders. Their structure and approval must be evaluated carefully.

WilmerHale's 2017 Venture Capital Report discusses several possible structures, while Pearl Meyer's September 2026 analysis explains why boards need to evaluate management incentives alongside existing equity rights.

The founder's financial outcome may therefore depend on two separate negotiations:

1. What the founder receives as a shareholder.
2. What the founder receives for remaining with the business or delivering the transaction.

Those amounts can have very different tax and economic consequences.

The Israeli employee angle: Section 102 options can become worthless

For Israeli startups, employee equity adds another complication.

Many Israeli employees receive stock options under Section 102 of Israel's Income Tax Ordinance.

Section 102 governs important aspects of employee equity taxation. It does not determine the liquidation priority of the underlying shares.

Consider an Israeli employee who owns 20,000 options with a $2 exercise price.

Suppose an acquisition waterfall allocates only $1 per underlying common share.

Exercising those options would cost $40,000 to acquire shares worth only $20,000 under the assumed transaction.

The options are underwater.

In many acquisitions, underwater options are canceled without payment, depending on the equity plan and transaction agreements.

If the waterfall allocates nothing to common shareholders, the employee's options may have no intrinsic economic value at all.

The employee might still receive a retention bonus or replacement award from the buyer, but that is a separate arrangement.

And the tax treatment can be very different

A $1 million equity payout and a $1 million retention bonus are not necessarily worth the same amount after tax.

For an Israeli tax resident, qualifying gains under the Section 102 trustee-based capital-gains track can benefit from a 25% base tax rate, subject to the applicable requirements.

High-income surtaxes can increase the marginal rate on the relevant capital-income portion to as much as 30%.

A retention bonus treated as employment income can instead be subject to ordinary marginal income tax rates, potentially reaching 50% for a high-income Israeli taxpayer, before other applicable charges.

Consider this simplified illustration:

These are illustrative marginal-rate calculations, not estimates of any particular employee's tax liability. Actual results depend on income thresholds, the award and payment structure, tax residency, applicable contributions, and other circumstances.

Importantly, not every Section 102 option payout qualifies entirely for capital-gains treatment, and a management carve-out is not automatically eligible for those benefits.

Before finalizing an acquisition-related incentive arrangement, the company should obtain Israeli and, where relevant, US tax advice.

The amount promised to an employee is not the same as the amount that employee will keep.

What founders should model before the next fundraising round

Imagine you are negotiating a new financing.

Investor A offers a higher valuation but requests senior liquidation preferences.

Investor B offers a lower valuation with standard 1x non-participating preferred stock.

Which is better?

The answer cannot be determined from valuation alone.

You need to understand how the round changes ownership, liquidation preferences, and the proceeds available to existing shareholders.

A higher valuation may reduce immediate dilution while introducing terms that make a moderate exit less attractive.

But additional capital could also enable growth that would otherwise be impossible.

The correct decision depends on both the probability of different outcomes and their economics.

Before signing the next term sheet, I would model at least three potential exits:

A disappointing exit: The company sells for less than the outstanding liquidation preferences.

A moderate exit: The company achieves a meaningful acquisition price, but some investors still prefer their liquidation preferences over converting.

A successful exit: The acquisition price is high enough that preferred investors benefit from conversion.

For each outcome, calculate:

• Proceeds to each preferred series.
• Proceeds to founders and common shareholders.
• Proceeds to employees holding options.
• The conversion threshold for each preferred series.
• The effect of additional financing and dilution.
• The impact of debt, transaction expenses, escrows, and management incentives.
• Estimated after-tax proceeds where material.

These are the calculations that turn a cap table into a decision-making tool.

A cap table tells you who owns the company. A waterfall tells you who gets paid.

We don't know Firebolt's actual liquidation preferences or how much its investors, founders, and employees would receive if a transaction closes.

Its reported acquisition talks are an illustration, not proof of any particular shareholder outcome.

But the underlying lesson is relevant to every venture-backed founder.

Founders spend months negotiating valuations.

They celebrate the announcement of a financing round and the increase in their company's paper value.

Yet the amount they eventually receive can depend on financing provisions signed years earlier.

Before raising another round, build a liquidation waterfall that shows what happens under several realistic exit scenarios.

Because the number that matters isn't only what your company is worth on paper.

It's what you and your shareholders actually receive.

Know what your next financing means for your exit.

Before raising another round or evaluating an acquisition offer, understand how liquidation preferences, dilution, and employee equity affect what you actually receive.
