Braemar Energy Ventures works with management teams who are skilled in their industry but who can benefit from Braemar's assistance with strategic direction and financing issues. Having worked with many early stage companies, the Braemar Energy Ventures principals understand the challenges that many young companies face and provide invaluable counsel to their portfolio companies on longer-term issues, allowing management to focus on daily operations.
