The Path to FirstUp

Our Mission & Values

At FirstUp, our mission is to bridge the gap between sales potential and delivered success. We believe that every organization has the capacity for growth, but may lack the tools or resources to reach the next level. Through integrity, accountability, and transparency, we serve as a trusted partner, providing sales and operational support necessary to turn high-level vision into high-impact results.

Our Founder

Leslie Fabian has spent over a decade refining the nuance of revenue generation and the discipline of a well run operation. With a track record that spans from supporting portfolios like Hilton, Marriott, and IHG to the fluid environment of a start-up, she specializes in establishing the protocols that turn uncertain processes into a permanent standard. Her tenure across hospitality, SaaS, and the non-profit sector has reinforced a universal insight: that the most successful organizations prioritize integrated sales and operational systems as the essential foundation for growth.


Whether leading sales outreach for high profile non-profit institutions or enhancing the operational mechanics of a start-up team, she ensures the quality of the work remains as high as the ambition behind it. To date, Leslie has been responsible for producing over $10 million in revenue, consistently outperforming projections by creating the plans that bridge the gap between sales strategy and operational excellence. As a former Partner of Sales & Operations, she knows that a business is only as strong as its daily habits. Ultimately, she helps build the quiet confidence that comes when a leader can finally stop shouldering the day-to-day and start focusing on the long-term vision.
