Investment thesis
Defiant is a venture fund reimagining what a VC fund can look like through a thematically-led, data-driven and product-centric approach to investing in B2B software and fintech. It backs early-stage founders and builds proprietary software and benchmarking products to add value beyond capital. The firm draws parallels between the cloud era's 'picks and shovels' middleware companies and today's AI market, expecting a new generation of tools to emerge. It believes defensibility in the age of large language models comes from proprietary workflow data, built-in growth loops and rapid experimentation, driving disruption across the modern business tech stack.
