South Loop Ventures

Zach Ellis Jr., the firm's Founder and Managing Partner, is responsible for all elements of fund strategy, investment, operations, and portfolio management. The firm's website lists one associate supporting sourcing and evaluation, with Ellis ultimately making the calls.

South Loop is intentionally generalist but publishes five sector tags where it claims particular access and expertise due to its Houston location: energy transition, healthtech, fintech, sportstech, and spacetech. Its website rejects pattern-matching in favor of backing founders it deems mold-breaking, regardless of sector.

The firm states it invests up to $500K at the pre-seed and seed stages. It does not publish a minimum check size or reserve-allocation strategy.

No. South Loop Ventures does not publicly disclose assets under management, a fund-formation date, or a named institutional limited partner base. Its website makes no reference to SEC registration or ADV filings.

Sourcing appears driven by Houston's industrial ecosystem and a network of named sector and senior advisors — including Mercury Fund's Blair Garrou, former BBVA Compass CEO Manolo Sánchez, and Texas Medical Center's John Reale Jr. The firm pitches proximity to energy, health, space, and sports infrastructure as a sourcing edge.

The firm frames undercapitalized diverse founders as a market inefficiency rather than a concessionary allocation, citing the sub-3% venture capital flow statistic on its site. It argues that lived experience produces strategic edge and positions this as its primary alpha thesis.

No direct corporate affiliation is disclosed, but the firms share significant operational DNA. Mercury Fund co-founder Blair Garrou serves as a senior firm advisor to South Loop, and both firms use GSqrd Consulting — of which Mercury's COO Winston Gilpin is co-founder — for fund administration.
