#Cleantechers -

The latest episode of Scaling Clean will be my last hosting the show, because someone else at Tigercomm will be taking over the microphone. I get to end my tenure in the host chair with a guest who’s spent a lot of time growing companies. Mark Lewis is a veteran of some small, obscure companies you've never heard of, such as @Credit Suisse and @General Electric.

From those, he became the CEO of Toronto-based ONEnergy, then got into fusion and investment. Mark's now managing director of Lime Rock New Energy, an innovative private equity manager that specializes in partnering with and growing clean energy companies. 

In his time, Mark has looked under the hood of many businesses, and I've wanted him on the show for at least two years. You’ll learn a lot from what he's seen by evaluating what works and doesn't in cleantech corporate leadership teams. 

Here are Mark’s B3P’s: 

9:07 - When a team member isn’t the right fit, waiting to make a decision only makes things harder. Trust your instincts, recognize misalignment early, and make the necessary change decisively and respectfully – knowing it can be better for both the individual and the organization.

16:17 -  Surround yourself with the best talent. You won’t always be the smartest person in the room, and you can’t be an expert at everything. So, create an environment where individuals feel valued, supported, and able to thrive alongside others.

23:28 - Stay focused on your vision and resist the temptation to chase every new opportunity. Discipline in saying “no” to a new shiny thing is essential to building a strong, sustainable business.

Thanks for coming on the show, Mark.
