Follow-on investment

A follow-on investment is an additional investment made by an investor already on the cap table, in a later round of the same startup. It serves two purposes: limiting the investor's own Dilution, and deploying more capital into companies whose potential has already been confirmed, since later-stage rounds are generally less risky than seed.

‍

This logic is not without pitfalls. The sunk-cost fallacy pushes some investors to pile follow-on money into already fragile holdings to avoid booking a loss, artificially keeping so-called zombie startups alive rather than reallocating capital to more promising deals.

‍

Venture funds structure their Investment period precisely to set aside a reserve explicitly for follow-on, distinct from the capital earmarked for new investments: a fund that burns through its follow-on reserve on its weakest holdings mechanically starves its best performers of growth capital exactly when they need it most.

For an investor, as for an advisor supporting a series of raises, telling apart a follow-on justified by genuine performance from a purely defensive one is a matter of allocation discipline, central to any financial structuring spanning multiple rounds.
