Operators before investors.
Stark Family Office is a single-family office based in Miami, FL and Paradise Valley, AZ, deploying permanent capital into founder-led businesses across consumer goods, hospitality, B2B services, and real estate — industrial, luxury home development, and multifamily.
Why we exist
We started Stark Family Office with a single conviction: the most enduring value in business is created by founders who are given the time, capital, and freedom to build properly.
Traditional capital structures impose timelines that conflict with long-term company building. Fund cycles force exits at the wrong time. LP pressure distorts decision-making. We chose a different path.
As a single-family office, we answer to no one but ourselves — which means every decision is made with the interest of the businesses we back, not a return schedule.
How we got here
Founded DigitalMGMT.
Built an ad operations consultancy from the ground up to help independent publishers monetize their audiences. Proved there was a scalable business in managing the full ad stack for content creators.
Co-founded Freestar.
Identified header bidding before it went mainstream — the technology that lets publishers run simultaneous open-market auctions for every ad impression. Turned it into a fully managed service and built Freestar around it.
Ranked #1 on the Inc. 500.
Freestar was named the fastest-growing private company in America, with 36,680% growth — a publisher partner network reaching over 70% of all U.S. internet users each month.
EY Entrepreneur of the Year.
Won the EY Entrepreneur of the Year award for the Mountain Desert Region. Named #1 on ASU's Sun Devil 100 — the top recognition for fastest-growing businesses led by ASU alumni. Deloitte ranked Freestar #31 on the Technology Fast 500 and #1 in digital media. ABRY Partners invested.
The investment shift begins.
Backed Laundry Sauce — a consumer brand building genuine customer loyalty through premium product and world-class fragrance — as the first move into permanent capital investing.
Stark Family Office.
Formalized the investment platform. Permanent capital. No fund lifecycle. No LP pressure. The freedom to back founders building businesses that last.
What guides us
Bad capital structure is a silent tax on every decision a founder makes.
We watched fund-backed companies optimize for the wrong milestones. Timeline pressure doesn't make businesses better — it makes them faster to exit. We built Freestar without fund-cycle pressure. Our portfolio companies get the same.
The best operators know the difference between speed and urgency.
Speed compounds. Urgency destroys. A business built under artificial urgency takes shortcuts it spends years unwinding. Patient capital isn't slow — it's precise.
Consumer trust is earned once and lost instantly.
The brands that last — Laundry Sauce, Cleaverman — earn genuine loyalty through product. Not performance marketing. Not a loyalty program. The product does the work. We back founders who understand this.
Most investors have never run anything.
We have. From ad operations at DigitalMGMT to building Freestar into the fastest-growing private company in America, we built businesses with our own hands. When a founder calls with an operational problem, we recognize it.
Concentration is a feature, not a risk.
Diversification is how capital protects itself from not knowing enough. We hold fewer positions because we do more work before we invest. We would rather be deeply right in five businesses than vaguely exposed to fifty.
