Miramar Digital Ventures

The firm relies almost entirely on warm introductions from existing portfolio CEOs, Executives in Residence, and fund advisors. Its own website states this explicitly, indicating a deliberate gatekeeping model that favors founder-referred opportunities over cold-inbound decks or banker processes.

Miramar operates as a traditional private equity firm raising capital from third-party limited partners, not a family office. It was formed in 2014 as a next-generation evolution of Miramar Venture Partners and deploys commingled fund vehicles for seed and early-stage venture investing.

Over 75% of its capital goes to companies headquartered in Southern California, with a particular concentration on founders educated at University of California campuses. The balance sits in Austin, Denver and Northern California, a footprint the firm describes as recently expanding into the Intermountain West and Southwest regions.

The firm describes itself as seed and early-stage, with team members who have operated across seed through public-company scales. While the firm does not publish a dollar range, its follow-on model signals concentrated reserving for seven to nine names per vintage, implying lead or co-lead economics at the Series Seed and A stages where it can influence governance.

Miramar does not disclose a formal team roster on its website or LinkedIn. Bruce Hallett is referenced in prior Altss records as a founder associated with the Miramar Venture Partners lineage. The firm does publish that its investment professionals and Executives in Residence include former operators from Broadcom, Qualcomm and Western Digital.
