Overview
Work Experience
Owner
2025 - Current
I created Fractional Partner because I believe that the best support for founders, startups, and investors isn’t always found in full-time hires or traditional agencies. Sometimes, what you really need is a partner you can trust — someone who can jump in, bring experience, and move things forward, without all the noise. Fractional Partner started as a platform to share real-world lessons from the startup and product world through a website and a podcast — and evolved into a place where founders and investors can find flexible, high-impact support when it makes sense. At this point, I’m focused on growing the knowledge side of Fractional Partner and continuing to build it for the long term. While I’m not actively seeking new projects right now, I’m always happy to connect, offer advice, and explore ways to collaborate when timing and capacity allow. If you're building something new, investing in bold ideas, or just want to swap thoughts, I'd love to hear from you.

Stringbean simplifies workflow management for property managers by streamlining vendor tracking, inspections, and task management. The platform provides real-time visibility, mobile accessibility, and actionable insights to help businesses operate more efficiently.

Through data-driven analysis, customer insights, and a hands-on approach, I’m helping shape Stringbean’s next evolution, ensuring it delivers greater efficiency, accountability, and ease of use for property managers and enterprise clients.
Value Creation
2024 - 2025
In a short time at Unbox Ventures, I’ve driven impactful results by recruiting 30 PhD graduates for our program through a combination of paid LinkedIn advertising and guerrilla marketing, including targeted email campaigns. I’ve also refined the long-term marketing strategy, introduced key subject matter experts to the team, and supported day-to-day operations in a lean and dynamic environment. My focus is on creating tangible value by connecting academia and entrepreneurship, empowering PhDs to transform their ideas into groundbreaking ventures.
