Take the Big Swing Without Betting the Company: The Downside Limiter

The stuck moment. A roofing contractor doing $2.8M a year gets the call: a retiring competitor will sell his crews and customer list for $400K, cash at close. The bank will fund it, with a personal guarantee. The upside is obvious: this could add $1.5M in revenue by next season. But if the crews walk or the customers don't transfer, that guarantee reaches into his house, his savings, everything. He's been staring at the LOI for two weeks. That's the signal: the upside is attractive, but the downside could be fatal.

The recipe: Downside Limiter.

1. Price the true worst case. Assume the deal fully fails, worse than just underperforming. Total the purchase price, debt service until wind-down, working capital burned, and what the personal guarantee actually exposes. Get one dollar figure.
2. Run the survival test. Put that number next to your liquid reserves plus 12 months of cash flow. If the worst case ends the business or reaches your family's finances, it's fatal, full stop.
3. Cap the downside before you negotiate price. Restructure until the worst case is survivable: seller financing, earnout tied to customer retention, staged buy-in, carving down the guarantee. If no structure gets it below fatal, walk. The upside never enters the math.
4. Set the tripwire now. Pre-commit one measurable exit condition and date ("retained revenue under $60K/month by month 6 = trigger the clawback"). Decide it before you're emotionally invested.

The AI move. Paste this in with your real numbers:

You are a risk-focused deal advisor for a small-business operator. Your only job is to limit my downside before I look at upside.

Context: [Describe the deal: what I'm buying or committing to, total money at risk including debt and personal guarantees, my liquid reserves, and my monthly free cash flow.]

Task:
1. Define the realistic worst case in dollars: assume the deal fully fails. Include debt service, working capital burned, and wind-down costs, not just the headline price.
2. Run the survival test: compare that number to my reserves and cash flow. State plainly whether the worst case is survivable or fatal.
3. Give me 5 specific ways to cap the downside (deal structure, staging, contingencies, insurance, walk-away clauses), ranked by how much risk each removes.
4. Write one tripwire: a measurable condition and date that, if hit, means I exit or stop funding.

Format: Worst case (dollar figure + how you got it). Survival verdict (one sentence). Downside caps (ranked table). Tripwire (one line).

Constraints: Do not mention the upside until the downside is capped. Use my real numbers: if any are missing, ask before answering. Answer bluntly, without optimism or hedging.

What it's worth: One fatal bet erases every good one that came before it. Twenty minutes here is the difference between a deal that can hurt you and a deal that can end you.
