Founder of Room & Pillar

Lyle studied Civil and Mining Engineering at Vanderbilt University and Colorado School of Mines, graduating in 1999 and obtaining his professional engineering license in 2002. After a year in commercial construction he joined his father, John Donan, Jr., at the business founded by Lyle’s grandfather in 1947 – Donan Engineering Co., Inc.

During the initial phase of his career, spanning over a decade, Lyle specialized in conducting forensic engineering investigations nationwide. He served a diverse clientele, including property insurance companies, FEMA, and legal professionals. It was during this period that he honed his entrepreneurial skills, guiding Donan’s transformation from a small family enterprise in Indiana and Kentucky into a national firm with four forensic investigation business lines and a workforce exceeding 400 employees by 2020.

Lyle is a serial entrepreneur and has been involved in numerous startups, including co-founding Seek-Now in 2011, Seed investing and advising Flyreel starting in 2016, and co-founding Source7 in 2018, where he continues to serve as Chairman of the Board. Lyle stepped down as the Donan CEO after a majority recapitalization in 2021, and now works fulltime leading his family office, Room and Pillar, investing, advising, and serving on boards for a portfolio of businesses across insurtech and proptech. 

Lyle is married with three children. He resides in Louisville, Kentucky, and spends time outdoors in the southern Appalachian Mountains, Florida coast, and Colorado Rockies.
