Leading Early-Stage Investors & Venture Capital Firms Funding Pre-Seed SaaS Startups Across the US

Pre-seed funding remains a crucial starting point for SaaS startups in 2025, as founders seek early backing to bring new products to life. The top active pre-seed investors and VCs funding SaaS startups in the US are supporting companies building innovative cloud software, B2B tools, workflow automation systems, and AI-driven SaaS platforms.


These investors provide the first institutional checks that help founders validate product-market fit, attract early customers, and prepare for seed-stage growth. Many are micro-VCs, accelerators, and angel syndicates based in leading US hubs like San Francisco, New York, Austin, and Seattle, while others are global early-stage funds investing in emerging American software startups.


Our database highlights investors currently funding and supporting pre-seed SaaS startups across the United States. Updated weekly, it provides founders, analysts, and business-development teams with real-time visibility into who’s actively investing in early-stage software-as-a-service companies in 2025.
