Helping Companies Navigate Growth
scroll for more


Capital is an important component for growth—but raising money is not the only ingredient for long-term success. Investors or a bank can provide capital, a search firm can help find talent, and consultants can offer business advice and implementation expertise.

But what if there was a single partner that could provide all of those things?

We created Range Light to fill that void in today’s marketplace, to provide business owners with a better way to navigate everything that comes along with growing a business.

We are an investment firm unlike others.


  • We invest our own capital to align ourselves completely as equity partners. That means we stand side-by-side with our portfolio partners through good times and bad. We don’t have to report our results to other investors, just ourselves, which gives us a very different mindset than traditional investment firms.
  • We are patient investors. Our goal is to build long-term partnerships, not quick exits. We work with management to build sustainable companies that we can all be proud of. Our investments don’t have defined time horizons.
  • We enjoy collaboration and understand the value it can create. Our greatest successes have come through working with great people all focused on a common goal. We know that the value of a cohesive group is always greater than the sum of its individual parts.
  • We are former business owners and operators.We know the challenges of running a business day to day. We like to be as actively involved in our portfolio partners as they’d like and we want to put our experience and expansive network to work for them.

Our values guide us

Our philosophy is based on five core principles. These principles are extremely important to us and guide every decision we make as a partnership.


It drives our decision-making process. While a return on our investment is important, building long-term partnerships means even more to us. Two critical components to the success of any partnership are alignment and respect. If you don’t have the same goals or mutual level of respect, this will always lead to dysfunction. Life is too short to be in conflict or unhappy.


We typically invest between $1 million and $20 million in equity to fuel growth, strengthen the business, or provide liquidity for existing share holders. We are willing to take a minority or majority stake depending on the circumstances.
We partner with companies that have annual revenue run rates of $1 million to $30 million.

Prior to starting CTC, Erich began his career in the financial industry at O’Connor and Associates in 1986. O’Connor was a pioneer in the derivatives business. Erich was running the US index market making operation when he left in 1995.
