Relentless is a New York-based seed-stage venture capital firm founded in 2026 by Damir Becirovic, following a decade at Index Ventures where he was promoted to Partner in 2020. The firm is built around a single conviction: that the best founders are doing their life's work, and that they deserve a partner who commits fully, deploying capital quickly, taking the board seat, and staying focused. Relentless closed its debut fund at over $80 million and is already actively investing.
Relentless is thesis-flexible at the sector level but founder-conviction-driven at the selection level. Damir Becirovic's track record at Index skews toward consumer, community platforms, creator economy, marketplaces, and software for traditionally offline industries and services. The firm also backs AI-driven companies, with initial investments including an AI legal accuracy platform and an AI investment diligence tool. The firm backs founders building category-defining companies, not incremental improvements.
Relentless Fund I closed at over $80 million in 2026. LP composition has not been publicly disclosed. The fund is SEC-registered via Form D filing. Fund I is already deploying, with initial investments including DiligenceSquared (YC F25) and Advocacy.
