The Journey
Keenan is a 3x AI/FinTech Founder, a 2x Y-Combinator alumni, current Angel Investor, Founder Coach and Board Advisor. In early 2024 - as a CoFounder - he exited his last venture backed startup: RYSE, a spin out from REZI which was a growth equity stage Prop-Tech company in the alternative assets space.
His team was the first ever to sell securitizations of residential lease cashflows to Banks and Hedge Funds. The platform stemmed from his 7 year career in commercial real estate finance, focusing on institutional debt origination and trading credit products while at Investment Banks and Hedge Funds in NYC, Chicago and London.
Fundraising Excellence
Over his career as an entrepreneur, Keenan has raised $225M+ in VC Equity, Venture Debt and Credit Facilities, demonstrating exceptional ability to secure funding across different stages and instruments.
Mentorship & Advisory
Keenan has been an EIR for TechStars in NYC/ATL/NOLA, an OIR for 43 North in Buffalo, Series A mentor at Google and a Coach at Morgan Stanley Inclusive Venture Labs in NYC.
Stratum Lab
In 2020, Keenan launched Stratum Growth - now Stratum Lab, a strategic advisory platform for both early to mid-stage startups. The firm specializes in servicing first-time startup founders and operators, guiding them to reach product-market fit through data-driven strategies, AI-powered automation, and revenue optimization frameworks.
