Ember Infrastructure

Managing Partner Elena Savostianova heads the investment team. The partnership group also includes Bob Kelly, Mary Weisskopf, Caleb Powers, and Peter Milligan. Operating decisions draw on an in-house bench of senior advisors and operating partners who provide technical oversight on portfolio companies.

Ember sources through the industrial and engineering networks of its operating partners and senior advisors. The firm targets middle-market businesses in fragmented infrastructure services sectors, where off-market or lightly marketed processes are common. Its operating partners frequently identify opportunities through existing industry relationships rather than broad auctions.

Ember pursues direct, control-oriented equity investments in middle-market companies and physical assets. There is no public indication that the firm makes commitments to third-party infrastructure or private equity funds. Its investment model is built around operational involvement in portfolio businesses.

The firm invests in established, revenue-generating businesses and assets rather than early-stage or development-stage projects. Its portfolio companies are typically middle-market operators with existing customer contracts, recurring service revenue, or operating assets that can be expanded through organic growth and add-on acquisitions.

Ember does not publicly flag exclusionary sectors beyond what its mandate implies. The firm's investment focus on resource efficiency and carbon-intensity reduction means it does not invest in fossil-fuel extraction, midstream energy infrastructure unrelated to the transition, or heavy industrials without a resource-efficiency angle.

Ember has not publicly disclosed the composition of its limited partner base. The firm operates as a private equity platform rather than a single-family office or permanent-capital vehicle, suggesting it raises discretionary funds from institutional investors, though no fund names or closes have been announced.

Ember publishes an annual impact report measuring sustainability outcomes across the portfolio, but it does not operate a separate philanthropic foundation or donor-advised fund. Its impact thesis is embedded in the investment strategy rather than managed through a parallel vehicle.
