About Idea Tree Advisory

At Idea Tree Advisory, we know that you have poured everything into building your business. And whether it’s now or sometime in the future, you want to create financial freedom and relieve yourself of the burden of your day to day responsibilities. In order to do that, you’ll need to sell all or part of your business to the right partner at the right time, for the right price. The problem is that mergers and acquisitions are not in your wheelhouse which can leave you feeling overwhelmed and unsure of how to proceed to achieve the best outcome.

We believe that every business owner ought to have an objective third party resource to prepare, guide, and eventually execute a deal that delivers the financial and personal results you deserve.

We know that you have a handful of advisors close to your business and choosing the right one to help you take the next step is hard. Which is why we have spent over 20 years providing objective, third party, investment banking advisory services to emerging marketing businesses in a way that has helped leaders secure financial freedom and move on to pursue their next dream.

Here’s how we do it: First, we conduct a thorough discovery and analysis process where we get to know your business inside and out so that can establish your goals for the transaction and form a realistic valuation. Then, we create and execute a strategy to help you achieve your personal and financial goals. Finally, we structure the transaction in a way that allows you to you own your future and move on to your next step.

At Idea Tree Advisory, we approach each process thoughtfully. Because when we can bring investors and businesses together in a way that allows both parties to achieve their goals, everyone succeeds. And we believe that the best deals, and the best relationships, are the ones where everyone wins.
