What our clients say

We’ve been with Capital Source for the better part of a year now. The team takes the time to understand our business, our needs, and our future goals. They are responsive and engaging, and very easy to work with!

— George Powell, Cambium Analytica

Our companies have been using Capital Source Group for a few months now, and they are great to work with. They are very responsive with how quickly and efficiently they get deals closed — both CEOs and I are extremely satisfied. They provide short-term financing at flexible rates and great terms. They’re a great partner for us, and we look forward to working with them to get our company back on track.

— Jim Hubenschmidt, KJ Manufacturing

I continue to work with Capital Source Group, consistently impressed by their support for hardworking small business owners. CSG’s capacity to provide funding is an ace in the hole. They foster transparent communication, conduct thorough yet efficient due diligence, and create innovative deal structures. I’ve witnessed clients become more organized and sophisticated after partnering with CSG, reflecting their commitment to each deal as a genuine partnership. As a former lender myself and a national credit bureau education ambassador, I primarily work with small businesses today and understand the challenges they face. In today’s marketplace, lending options can be limited, making Capital Source Group an invaluable resource for common-sense solutions. I highly recommend them to clients seeking swift and straightforward funding solutions.
