FirstMile Ventures is a Colorado-based pre-seed and seed venture-capital firm founded by Bill Miller in 2014 and legally identified as FirstMile Ventures, LLC in its SEC adviser filing (CRD311699). Its current public team includes founder and Managing Partner Bill Miller, Partner Aaron Stachel and Austin-based Venture Partner Zaz Floreani. The firm focuses on founders building technology companies in Colorado and Texas, offering direct partner support from the first institutional round through readiness for Series A. Its portfolio spans enterprise AI, cloud infrastructure, robotics, cybersecurity and healthcare technology, including Kamiwaza, BurstIQ and gut-brain care developer SideBy Care. The firm’s three flagship fund generations and five SEC-reported legal vehicles are distinguished from parallel Colorado Venture Capital Authority programmes. In 2026, Aaron Stachel publicly confirmed a $25 million close for Fund III; that aggregate commitment is not assigned in full to either individual 2024 legal vehicle, and asset values reported in FormADV are not fund closes. The firm has made more than seventy investments. Its earlier founder angel investments and fundraising by companies Bill previously led are distinct from FirstMile’s own fund sizes. The unrelated FirstMile logistics/shipping business and FPV Ventures are excluded.
