The Term Sheet Clause Most Founders Sign Without Reading

Saim Abbasi has sat on both sides of a term sheet. As a founder, as an operator during an acquisition, and now as an investor at Iron Key Capital. The clause that causes the most damage is almost never the one founders spend time on.

Founders argue about valuation. They negotiate the option pool. They fight over board seats. And then they sign a drag-along provision without reading it closely, and two years later that clause determines their outcome more than anything else in the document.

Drag-Along: The Quiet Control Clause

A drag-along right allows a majority of shareholders, usually the preferred investors, to force all other shareholders to approve a sale. The mechanism sounds reasonable in theory. In practice, it means a group of investors can agree to sell your company at a price and on terms you disagree with, and you are obligated to go along.

The version that really hurts founders is one where the drag-along threshold is low. If preferred investors holding 35% of the company can drag the rest, a small coalition of early-stage VCs can accept an offer that returns them 1.5x on a preferred-plus deal while your common shares get nothing. Saim saw this happen to a founder in his network in 2022. The cap table was clean on paper. The drag-along provision made it irrelevant.

Pro-Rata and the Creeping Dilution

Pro-rata rights let existing investors maintain their ownership percentage in future rounds by investing alongside new money. This sounds founder-friendly because it shows existing investors have confidence in the business. It can also create a structural problem.

When pro-rata rights compound across multiple rounds, early investors can lock up a significant portion of each future round's allocation. This leaves less room for new strategic investors whose networks and relationships might matter more at that stage. Founders who needed the Series B investor's customer relationships end up with a smaller check from them because pro-rata ate the allocation.

What to Negotiate Instead

The clauses worth fighting for are the ones that preserve founder control at the moment of a sale. A high drag-along threshold, ideally requiring 70 percent or more of all shares, gives founders real protection. Sunset provisions on pro-rata rights after a certain round limit the compounding effect. And any anti-dilution clause should be weighted average, not full ratchet, or you are handing investors a weapon for future down rounds.

Saim Abbasi's standard advice to any founder raising a first institutional round: find an attorney who does nothing but startup financing, not a generalist. The cost of good counsel at the term sheet stage is trivial compared to the cost of a bad provision that triggers two rounds later.

"Every term sheet is a negotiation over who controls the outcome. Most founders only realize that after it is too late."
