“Russell has been an invaluable investor and advisor to Treehouse. His advice is thoughtful and considered. He is one of a select group of investors who really take the time to understand the finer points of what we're building. He has an incredibly diverse network and has matched us with both investors and high leverage partners and he's my go-to for advice on clean tech.”

“Russell has been an assertive and hands-on investor since day one. Most investors ask how they can help, but Russell proactively identifies opportunities to activate him based on how his network and experience uniquely can accelerate our progress. He referred one of our top Founding Engineer candidates, provided data to help us manage our headcount model, and introduced multiple prospective channel partners.”

"Russell is the investor who lives out his promise to help his companies. He will roll up his sleeves to help on a problem, leverage his network, or push you with a question you need. You won't get useless 'update’ meetings in working with Russell, but you will get help from someone who truly cares about your team, your mission, and you if he invests.”

"Russell is the exact type of investor you want in your corner as an early-stage founder….Russell has become an invaluable sounding board and connector for Amber, helping us evaluate the pros and cons of critical decisions and brokering introductions to relevant partners, candidates, and investors."

"Russell is the investor you can always count on. He approaches every challenge as a true partner and gives you the confidence to take on the toughest problems.... he’ll introduce you to your first customers and future investors, but most importantly, his belief and support in you, your team, and your mission will be unwavering."
