Who We Are
Overtime Capital Group
Overtime Capital Group is a boutique investment and wealth consulting firm founded by former professional athlete Justin Grube. We specialize in helping high-income earners — especially athletes, entrepreneurs, and industry leaders — build generational wealth through strategic access to alternative investments.
With a foundation rooted in elite performance, discipline, and long-term thinking, Overtime Capital Group curates and advises on direct investment opportunities across oil & gas working interests, land development, and income-producing real estate. Our team is deeply involved in each deal we present, offering clients access to institutional-grade assets often unavailable through traditional advisory channels.
We bridge the gap between financial education and actionable investment strategy — helping our clients move smarter, reduce tax exposure, and create income that outpaces their career timelines. From PDP-producing oil fields to vertically integrated land syndications and real estate, every opportunity we consult on is vetted for performance, transparency, and impact.
At Overtime, we don't sell products — we build partnerships. Whether you're coming off your first contract or transitioning from a successful career, our mission is to empower you to master wealth like a champion.
Our Strategic Partners
Our Team
Founder & CEO
Justin Grube is a former collegiate and professional athlete turned investor, entrepreneur, and elite performance coach. As the Founder of Overtime Capital Group, Justin helps athletes, entrepreneurs, and high-income earners turn short-term earnings into long-term legacy through strategic investment consulting.
With 20+ years in sports performance, coaching, and leadership, Justin brings a rare edge to the private capital space — blending discipline, vision, and drive. He’s built multiple successful ventures including Tailored Athletics (a nationally ranked 7v7 program), Tailored Projects LLC (a multi-state construction company), and has coached and competed at the highest levels of CrossFit, football, and strength development.
Justin’s passion is helping others win — on the field, in business, and in life after sports. Whether it’s navigating oil & gas investments, reducing tax burdens, or building generational wealth, his mission is clear:
Help top performers move smarter with money and turn earnings into legacy.
Proved Fields. High Yields. Elite Access.
Dyno Petro is redefining what it means to invest in oil & gas. They source proved undeveloped drilling locations in established fields, where infrastructure and production potential are already in place.
That means fast paybacks (typically 9–18 months) and long-term cash flow projected for 10–20 years. Their models are risk-aware, using strict land-approval standards + operational improvements (recompletions, reworks) to unlock upside.
With Dyno Petro, you’re not chasing hype — you’re entering deals built for serious returns from the ground up.
