Tyler Lowenstein

Tyler G. Lowenstein is a Principal on the Business Development team at Sentinel Capital Partners, a New York–based private equity firm focused on the lower middle market. His mandate is deal origination — sourcing and cultivating relationships with intermediaries, bankers, and owners to bring proprietary and intermediated deals into the firm's funnel — rather than making early-stage or angel investments.

Lowenstein joined Sentinel in 2018 as an Associate and has since risen to Principal (some third-party databases such as ZoomInfo and Wiza list his title as Vice President, Business Development, reflecting an earlier or overlapping title). Before Sentinel, he spent three years in Piper Jaffray's (now Piper Sandler) Investment Banking Analyst Program, where his work centered on agriculture, clean tech, and renewables coverage.

He holds a BA in Economics from the University of Minnesota, where he was a member — and reportedly captain — of the NCAA golf team. Outside the firm, Lowenstein is the founder of The Back Nine Network, a nonprofit that connects former NCAA golfers for continued competition and professional networking.

Sentinel Capital Partners itself is one of the more established lower-midmarket buyout firms in the U.S., having closed $5.2 billion across its seventh private equity fund and second structured-capital fund in 2022 (and $2.15 billion in its sixth fund in 2018). It has acquired dozens of platform companies and completed numerous exits across its four core sectors.

• Sources control-buyout and structured-capital opportunities for Sentinel — friendly, majority-ownership transactions partnering with existing management teams, *not* minority seed or angel checks.
• Targets established, profitable companies (up to ~$65–80M EBITDA) with solid fundamentals in Business Services, Consumer, Healthcare Services, and Industrials.
• Firm deploys roughly $100M–$350M of equity per platform and actively pursues tuck-in and transformational add-on acquisitions to build platforms.
• Sentinel's stated approach emphasizes partnering with "entrepreneurial executives to buy and build" companies in the U.S. and Canada and working hands-on with management to drive operational improvement and growth.
• Geographic focus is North America (U.S. and Canada).
