Think Big Ventures

Darwin Ling, the founder and sole general partner, makes every investment decision. He operates a concentrated portfolio with no investment committee, supported by a small network of venture partners who are often exited founders from the portfolio. The firm has maintained this solo-GP structure since 2014.

Initial checks range from $250,000 to $2 million at the pre-seed and seed stages, with capital reserved for follow-on investments through Series B rounds. The firm leads or co-leads roughly half its deals and prefers to take a board seat when leading. Think Big Ventures does not participate in later-stage growth rounds outside its existing portfolio.

Proprietary deal flow derives from Ling's personal network of technical founders and the firm's reputation in the Midwest startup ecosystem. Portfolio companies frequently refer other founders, and the firm's willingness to invest in Kansas City, St. Louis, Denver, and Minneapolis — markets with less venture density — creates an origination advantage. The firm also maintains relationships with Midwestern university tech-transfer offices.

Think Big Ventures invests exclusively in direct equity deals at the company level. The firm does not allocate to other venture funds or participate as a limited partner in external vehicles, concentrating all deployment into its own direct portfolio construction.

The firm does not invest in hardware-heavy deep tech, consumer mobile applications, or capital-intensive cleantech manufacturing. Its investment thesis concentrates entirely on asset-light enterprise software models where the general partner's technical background provides an underwriting and post-investment support advantage.

The firm has not publicly disclosed the composition of its limited partner base. Given the solo-GP structure and regional orientation, the investor base likely includes family offices and high-net-worth individuals rather than large institutional allocators, though this has not been confirmed in public filings.

The firm co-invests regularly alongside other seed-stage managers and occasionally syndicates deals with angel networks in the Midwest. When leading a round, Think Big Ventures typically structures a priced equity round rather than convertible notes, reflecting a preference for clean cap tables and standard governance terms.
