## Questions

### How does Tank Stream Ventures source proprietary deal flow in Australia?

Tank Stream's sourcing relies heavily on Rodrigues's network from his BlueChilli tenure and Carnegie's long-standing Australian deal relationships. The firm prioritizes founders with deep domain experience who have worked inside the problem they are solving — a posture that naturally narrows the funnel toward repeat-operator networks and ex-tech-executive circles. Tank Stream does not run a public scouts program or content-marketing engine, leaning instead on direct GP-to-founder outreach.

### Is Tank Stream Ventures structured as a pure venture firm, or does it operate differently?

Tank Stream is a hybrid venture firm. It runs a direct-investment book targeting Australian seed-to-Series B technology companies, but it also allocates fund capital into US and global venture fund commitments — a fund-of-funds sleeve that most Australian pure-play VCs do not maintain. This structure gives the firm's LP base a portfolio effect across domestic direct deals and international managed pools.

### Does Tank Stream participate in fund commitments or only direct deals?

Tank Stream actively participates in both direct deals and fund commitments. The direct side has backed Australian companies such as corporate learning platform Go1 and enterprise SaaS company Expert360. On the fund-of-funds side, the firm has historically placed capital into US top-quartile venture managers, though it does not publicly disclose the specific manager relationships.
