The bridge round you didn't realize was a down round

At one company, the founder took a $5M bridge at the same price per share as his Series A. The headline was clean: flat round, no down. He told the team. He told the press. He told himself the company had held its valuation through a hard market.

Eight months later, a Series B lead walked him through the exit waterfall during diligence. That deal didn't close, but the education did. The bridge carried a 2x participating preference, a full anti-dilution ratchet that had already triggered, and a pay-to-play that had quietly wiped out his original angels.

Say the company exits under $100M: the bridge takes all of it. In our example, an exit between $100M and $200M leaves the founders with less than the bridge put in. The flat round was a down round, written in legal terms instead of price.

Headline valuation is the least informative number on a term sheet. It's the number the founder repeats, the press prints, and the board slots into the deck. It's also the number the investor can give up most easily, because every dollar of headline can be clawed back through structure the founder hasn't the training or patience to model.

The structured bridge is the common shape. The price holds. The terms turn hostile. Preferences stretch from 1x non-participating to 2x participating. Anti-dilution shifts from weighted-average to full ratchet. Pay-to-play punishes any investor who doesn't reload. A pro-rata right becomes an obligation. Each move is invisible at the headline and decisive at the exit.

The diligence that catches this isn't legal work. It's arithmetic. Build the waterfall at three exit values: the current mark, half of it, and double. Run the new terms through each. Your take-home dollars at each exit, before and after the round, is the actual deal. If the terms cut your take-home at any plausible exit, the bridge is a down round. That's the same reflex as reading valuation off sales, not off the money raised.

The reason the work gets skipped is psychology, not math. Modeling the bad scenarios threatens the story the founder is selling everyone, himself included. The headline keeps the story alive. An honest waterfall usually kills it. Founders pick the story, the same way a raise can paper over the wrong problem.

The bill comes due at the exit, when the story is over and the waterfall is the only page that matters. The bridge held the price. It didn't hold the company. Read the terms. Run the math.
