At RB Unlimited, LLC, we specialize in providing fractional chief operating officer services to small and scaling companies led by subject matter experts.
We typically work with subject matter experts who have launched successful businesses but have reached a point where they can no longer manage, nor want to manage, the day-to-day operations of their business, or know how to scale the business to the next level. We provide a second brain to the founder and the helping pair of hands to execute.
At RB Unlimited, LLC, we take a holistic approach to consulting. We work closely with our clients to understand their goals and challenges, and develop solutions that address their specific needs. Our approach is collaborative, transparent, and results-driven.

Turning concepts into real, functioning businesses.
We work with founders at the earliest stages to refine the idea, validate demand, build the operational foundation, and bring the product to market. From business models to first customers, we help you launch with clarity, structure, and momentum.

Transforming traction into sustainable, systemized growth.
For companies that have found product–market fit, we optimize operations, build repeatable processes, strengthen financial and data systems, and prepare the business to scale. We partner deeply with leadership to unlock efficiency, expand revenue, and stabilize the foundation for rapid growth.

Guiding your company through acquisition.
Whether you’re exploring M&A, fundraising, or a strategic handoff, we help maximize valuation and minimize friction by preparing financials, strengthening operations, and helping negotiate maximum business value for the founders.
