energy option. Tom founded and led Avantus (formerly known as “8minute Solar
Energy“), to become one of the largest and most profitable solar and energy
storage companies in the United States and the largest in California,
including delivering over 17% of Los Angeles’ power.

When Tom sold his interest in Avantus’ development business to KKR in
mid-2024, it had delivered over $1 billion in profit and secured over $10
Billion in power purchase agreements and project financings with a pipeline of
over 30 GW of solar and 90 GWh of energy storage, capable of powering the
homes of more than 20 million Americans day and night.

Tom’s family office investment firm, 1st Avenue Capital, is building teams for
the next generation of advanced solar power system architecture and AI to
aggressively drive down the cost of and equitable access to clean and reliable
