## About

SI Capital was established as a single family office in Farmington Hills. Its capital allocations trace to principals who built exposure through Earth Capital Holdings, the parent group that also sponsors the Nobel Sustainability Fund. The firm deploys across private equity, real estate, private credit and direct co-investments. Confirmed positions include a minority stake in Escotel Investments acquired with Grupo Ecos in 2015 and support for the Liechtenstein Group's joint venture with Glide Energy. Geographies span Europe, North America and South America. Investment stages center on growth equity with exposure to energy efficiency and solar PV assets. AUM stands at $5B. The firm maintains a relationship with Fond-ICO Global, which committed €10 million to its Energy Efficiency Fund II in 2016. Additional offices are not disclosed. A 2019 transaction saw Lietuvos Energija Renewables acquire the 94 MW Pomerania wind project developed by investee IGE. The structure links to Earth Capital Holdings, which supplies the Nobel Sustainability Fund as the anchor investor in SI Capital R&S I. This creates a hybrid vehicle that combines family capital with external mission-related commitments while retaining direct control over renewable energy deployments.
