Frequently asked questions
Who runs investment decisions at 3.5.7.11?
Founder Dale LeFebvre serves as Executive Chairman and appears to drive investment and operational strategy. The firm's website lists two additional Principals — Delvin Kelly and Jay Scherer — alongside a team of Operating Partners and Vice Presidents, but does not specify an independent investment committee or exact decision-making hierarchy.
How is 3.5.7.11 structured relative to a conventional family office?
It operates as a hybrid between a single-family office and an industrial holding company. The firm describes itself as a 'controlled investment family office' that develops proprietary IP and selects operating partners based on shared values, a model it calls ValueCentric™ synergy. It does not appear to manage third-party capital or operate a fund structure.
Does 3.5.7.11 participate in fund commitments or only direct deals?
All publicly disclosed positions are controlled operating companies — Anvil Industrial, 3E via Benton-Georgia, Conscious Data Centers, 1155 Infrastructure Solutions, Diversified Utility Services, and others. There is no evidence of fund-of-fund commitments or minority co-investment activity alongside external GPs.
What investment stages does 3.5.7.11 target?
Available evidence points to control buyouts and outright acquisitions of established industrial and infrastructure-services businesses. The 2014 acquisition of Benton-Georgia, supported by a $21 million junior term loan from Monroe Capital alongside a Wells Fargo ABL facility, suggests a buyout-oriented approach rather than venture-stage investing.
Which sectors does 3.5.7.11 explicitly avoid?
The firm does not publish a negative-sector list. Publicly disclosed holdings concentrate in energy infrastructure, industrial services, data centers, and finance, implying limited — if any — activity in consumer internet, healthcare, or biotech, though no explicit exclusion is documented.
Where does the underlying wealth come from?
The specific source is not publicly attributed to any single family branch or disclosed liquidity event. Founder Dale LeFebvre's prior career includes founding 35711 Investments and Anvil 1, but no detailed wealth-origin trail is documented in firm materials.
Does 3.5.7.11 maintain philanthropic structures?
Founder Dale LeFebvre made a $750,000 donation to the University of the Virgin Islands in April 2022 and is involved with the Horatio Alger Association, which selected him as a 2024 member. The firm does not disclose a separate foundation structure.
