Meet the Team
Tim Horst
Founder & CEO
Tim started his real estate career as a licensed agent in 1991. After 18 years working for other large franchise real estate companies, he started Summa Real Estate Group in 2009. He quickly learned that there were few options for new startup real estate companies. He had to cobble together several expensive third party tools just to operate with efficiency. Because of this, he created the technology behind Summa Basecamp.
Andrew Helenius
Technology
Andrew is a software engineer from Portland, Oregon. He graduated from Portland State University with a degree in Computer Science, and now with over ten years of experience in the industry he has shifted his focus to entrepreneurial pursuits, joining Tim on building Summa Basecamp.

Outside of work you can catch him running, hiking, or chilling with his cat!
