Why does Earnout matter?
It bridges a valuation gap when the buyer and seller disagree about future performance, but the founder no longer fully controls the levers that drive the milestone once the business is folded into a larger company, roadmap priorities, resourcing, and go-to-market decisions increasingly belong to the acquirer. A founder who agrees to an earnout without negotiating real operational autonomy over its inputs is betting on an outcome they can no longer fully drive.
What does Earnout look like in practice?
Suppose a $20,000,000 deal is structured as $12,000,000 at close and up to $8,000,000 over two years if the acquired product reaches $5,000,000 in ARR. Six months in, the acquirer reassigns the acquired team's engineers to a different internal priority and folds the product's go-to-market into its own sales organization. The founder, now an employee, has far less control over hitting that $5,000,000 bar than they did running an independent company, and a dispute over whether the acquirer acted in good faith toward the earnout follows.
What are the common mistakes with Earnout?
- Agreeing to earnout metrics without negotiating operational autonomy over the inputs that actually drive them.
- Leaving the metric's calculation method and owner ambiguous. This is the single most common source of earnout disputes.
- Treating earnout dollars as guaranteed when modeling personal outcomes, rather than as the contingent, control-dependent payment they actually are.
- Not addressing what happens to the earnout if the founder is terminated, or the division is sold or shut down, before the earnout period ends.

- Letter of Intent (LOI)A short, mostly non-binding document signed early in an acquisition that lays out the proposed price, structure, and timeline before either side commits to full due diligence and definitive legal documents.
- Asset Sale vs. Stock SaleThe two basic ways to structure an acquisition, the buyer purchases specific assets and liabilities out of the company (asset sale), or the buyer purchases the company's equity itself, liabilities included (stock sale), and the choice changes who owns what, who owes what, and how much tax each side pays.
- Acqui-hireAn acquisition primarily motivated by hiring the target's team rather than its product, revenue, or customers, usually structured with most of the deal value going to retention packages for key employees rather than to shareholders at closing.
