Liquidation Waterfall
A liquidation waterfall is the calculation that determines how exit proceeds are distributed across preference stack, share classes, and option pools at exit. Exit proceeds include acquisition cash, public offering proceeds, and dissolution distributions. The waterfall is modeled as a series of "buckets" that fill in priority order until the proceeds are exhausted. It is the math that determines what each shareholder actually receives, and the analysis founders most consistently postpone until it's too late to change.
The waterfall fills in roughly this order: secured debt first (rare for venture-backed startups, but present if there's outstanding venture debt with collateral), then unsecured debt and trade obligations, then preferred stock with liquidation preference (in reverse order of seniority, latest investors first, since they typically negotiated senior preferences), with each tranche claiming its preference amount (typically 1x the investment, sometimes 1.5x or 2x for later rounds in tough markets), and within preferred, participating preferred also gets a pro-rata share of remaining proceeds alongside common. After preferences are satisfied, common stock (founders, employees with exercised options, advisors) splits whatever remains on a fully-diluted basis. The most consequential wrinkle: participation rights (full participation, capped participation, or non-participation) dramatically change the math. Non-participating preferred chooses between taking the preference or converting to common; participating preferred takes the preference AND shares in remaining proceeds. The scenarios where founders get wiped out: mid-range acquisitions (a $50M sale of a company that raised $80M with 1x non-participating preference returns the preference and leaves nothing for common; the same sale with participating preference still leaves nothing). Modeling tools include Carta, Pulley, AngelList Stack, Capshare, and dedicated waterfall-modeling consultants for complex stacks.
Ryan's Take
The liquidation waterfall is the math that breaks founders' hearts every day in mid-range acquisitions. The acquisition price looks like a win; the waterfall reveals that the preference stack consumed everything before common saw a dollar. The defense is modeling waterfalls under realistic exit scenarios at every round, not just the optimistic one. The question to ask is "at what exit price do my employees and I actually see meaningful proceeds," and the answer is usually higher than founders assume because the preference stack accumulates faster than the headline raise number suggests.
What founders get wrong: Modeling the waterfall only at the success-case acquisition price. The cases that hurt are the mid-range outcomes ($30 to $80M acquisitions after $40 to $100M in venture funding), where the preference stack consumes most of the proceeds and the founders walk away with far less than the headline price would suggest. Always model at three scenarios: optimistic, expected, and the floor at which common still gets meaningful proceeds.

FAQ
What is a liquidation waterfall?
The calculation that determines how exit proceeds are distributed across the preference stack, share classes, option pools, and other claims when a company is sold or wound down. Models as a series of buckets that fill in priority order until the proceeds are exhausted.
What order does a liquidation waterfall fill?
Secured debt first, then unsecured debt and trade obligations, then preferred stock liquidation preferences (in reverse order of seniority, latest investors first), then common stock if anything remains. Participating preferred also gets a pro-rata share of remaining proceeds alongside common.
Why do founders sometimes get nothing in an acquisition?
Because the liquidation preference stack consumed all proceeds before common shareholders see anything. Common scenarios: a $50M sale of a company that raised $80M with 1x non-participating preference returns the preference and leaves nothing for common. Mid-range acquisitions hurt founders most.
