autofinanciarse

To fund oneself or one's own project without outside investors, loans, or subsidies — common in business, politics (campaigns), and the arts (independent films, albums).

• La campaña decidió autofinanciarse para evitar donantes externos. — The campaign decided to self-finance to avoid outside donors.
• El documental se autofinanció con ahorros del director. — The documentary was self-financed with the director's own savings.
• Muchas startups intentan autofinanciarse en sus primeros meses. — Many startups try to self-fund in their first few months.

Don't confuse with plain financiarse, which is neutral about the funding source — autofinanciarse specifically emphasizes that the money came from the entity itself, not investors or the state.
