Acquihire — buyer wants the team, doesn't really want the product. Typical at $1-10M acquisition. Equity rolls into vested stock at buyer. Useful when the product has stalled but the team is strong. Result for founders: usually a 3-4 year buyer-stint, modest payout.
Strategic acquisition — buyer wants the product or customer base because it fits a strategic gap. Pricing reflects strategic value (not just multiples). Typical at $20M-$2B. Best path for most founders if available; depends on having a clearly strategic asset.
PE / financial acquisition — buyer wants steady cash flow at an EBITDA multiple. Typical for bootstrapped businesses with strong profit margins, ARR >$5M, low growth but very stable. Most founders dismiss this; for B2B SaaS at $5-30M ARR with healthy economics, it's often the cleanest path.
Secondary — partial sale of founder/early-employee equity to investors during a primary round. Not an exit; a partial liquidity event. Useful at $20M+ ARR for de-risking founder personally without giving up the business.
The mistake: defaulting to "strategic acquisition by Google" as the goal. ~95% of acquisitions are not Google buying. Plan for what's actually likely.
