Tank Stream Ventures

Tank Stream Ventures (TSV) is an early-stage venture capital firm founded in 2013 and based in Sydney, Australia, operating within the BridgeLane Group. It is a web-technology-focused fund backing seed and Series A startups across Australia and the broader Asia-Pacific region, with a focus on mobile, e-commerce, SaaS, social media, networking and online-marketplace businesses. The firm prefers founders driven by a problem-solving vision rather than a solution-led one, treating technology as an enabler, and supports entrepreneurs with an obsessive vision to disrupt existing industries and improve lives through technology. Check sizes range from roughly $500K to $10M, with typical seed cheques of $1M to $5M, and the firm is willing to lead. TSV was founded by Jonathan Lui, Markus Kahlbetzer, Rui Rodrigues and Tim Fung; Markus Kahlbetzer, also founder and CEO of BridgeLane Capital and co-founder of Tank Stream Labs, is a founding partner, Rui Rodrigues serves as managing partner, and venture partners include Nathan Gooley, former head of private equity and funds management at BridgeLane, and Francisco Caffarena, with Airtasker founder Tim Fung as a director. As a sub-organization of BridgeLane Capital, TSV shares much of BridgeLane's portfolio and the two frequently co-invest. Across roughly 19 portfolio companies, holdings include Go1, which became a unicorn in 2021 about five years after TSV first invested, and Airtasker, which listed on the ASX in March 2021 at a roughly $198M market cap. The TSV fund is now fully deployed and considered inactive, with new opportunities directed through the BridgeLane Group.
