Capital Calls Making investments in portfolio companies requires the venture firm to start "calling" its limited partners commitments. The firm will collect or "call" the needed investment capital from the limited partner in a series of tranches commonly known as "capital calls". These capital calls from the limited partners to the venture fund are sometimes called "takedowns" or "paid-in capital." Some years ago, the venture firm would "call" this capital down in three equal installments over a three year period. More recently, venture firms have synchronized their funding cycles and call their capital on an as-needed basis for investment.
