A drag-along right lets the stockholders who approve a sale of the company require every other stockholder to vote for it and sell on the same terms. It keeps a few holdouts from blocking an exit that the board and most of the cap table want. Who can pull the trigger, and what protections the dragged stockholders get, are what founders should focus on.
Key takeaways
Buyers want 100% of a company. Without a drag-along, a single small stockholder (an early angel, a departed co-founder, a former employee with a few shares) can hold up a sale or demand special terms. The drag-along requires them to vote for the deal and sign on the same terms as everyone else in their class. That protects the investors who negotiated it, and it protects founders who want to sell.
Buyers rarely close with only a bare majority on board. They usually want nearly every stockholder to approve the deal and give up any claims against it. The drag-along is how the company collects those signatures. See What Happens Between the LOI and Closing When I Sell My Startup?
The standard financing documents (NVCA-based) let the parties choose the trigger. Common versions, from most to least investor-friendly:
An example. A Series A lead buys 60% of the Series A preferred, and the Series A is 30% of the company. The lead owns 18% of the company. If the drag needs only a majority of the preferred, that one investor can force a sale on its own. If it also needs the board and a majority of the common, the founders have to agree too.
In practice, companies rarely have to go to court over a drag-along. Its main job is to give a holdout a reason to sign.
A well-drafted drag-along conditions the forced sale on terms like these:
Usually once they become stockholders. When a SAFE converts in a priced round, the holder typically signs the voting agreement that contains the drag-along. That’s why the trigger you agree to in your first priced round matters: it will bind almost everyone on your cap table.
They work in opposite directions. A drag-along lets the approving stockholders force others to sell. A tag-along (or co-sale right) lets other stockholders join a sale of someone else’s shares, so one holder can’t sell out alone. Priced rounds usually include both: the tag-along in the ROFR and Co-Sale Agreement, and the drag-along in the voting agreement. See Right of First Refusal.
