stake (as in providing material assistance to launch an enterprise, often in exchange for an ownership interest or share of the profits) n.; v.t. grubstake

[Like “stake” itself, this word can be used as a noun or a verb.]  In under five years [Krammer & Stoudt] the brand has gone from being a Los Angeles obscurity to a cult label lauded by the industry “We gave up everything we had to do this,” Ms. Nearburg said, referring to the careers [that she and her husband] formerly held. “We started out with zero and knew nothing,” said Mr. Nearburg, who grubstaked the label with money the pair got from their honeymoon. (Guy Trebay, “City Slickers,” The New York Times, 02/07/2018.)

This word, when used in the sense above can also be synonymous with invest, capitalize and finance.
