The Pull to Build: Joubin Mirzadegan on Grit and Starting Roadrunner

Grit · Dec 8, 2025

From sales leader to Kleiner Perkins partner and founder, Jubin shares his journey and the 'why' behind his new AI startup, Roadrunner.

Founding a Startup Is the Ultimate Self-Test, Not a Pre-Defined Path

The motivation to start a company wasn't about a guaranteed outcome but about embracing the ultimate test of one's capabilities. The realization that most founders, regardless of experience, are figuring it out as they go is empowering. It reframes the founder journey from a path for experts to a challenge for the determined.

Use a Niche Podcast as a Strategic Tool to Solve a Specific Business Problem

The 'Grit' podcast wasn't created for general brand building. It was a targeted solution to a specific problem: Kleiner Perkins needing to identify and build relationships with the best CROs for their portfolio companies. This reframes content creation from a marketing activity to a strategic, problem-solving mechanism.

AI Can Create an 'Omniscient Nervous System' for Complex Sales Deals

By analyzing past quotes and data, AI can instantly recommend the optimal deal structure for a new quote—maximizing commission for the rep and aligning with business goals, putting revenue back in motion.

Effective VC Talent Support Requires Embedding Operators Before Recruiting

Most VCs fail at talent support by simply matching logos on a resume to a portfolio company. A better model is to first embed operators (e.g., fractional sales leaders) into the startup. This provides the deep, nuanced context required to find candidates who fit the specific business and culture, leading to better hiring outcomes.

Hire 'Dolphin' Operators Who Oscillate Between High-Level Strategy and Tactical Execution

The most effective operators, dubbed 'dolphins,' can fluidly move between altitudes: operating strategically at 10,000 feet with founders, managing at 5,000 feet, and executing tactically in the weeds at 1,000 feet. This ability to oscillate is a key trait to hire for, especially in advisory or early-stage leadership roles.

A Contrasting Upbringing Can Forge a Powerful Leadership Mix of Discipline and Irreverence

Jubin attributes his dual-sided personality—taking some things very seriously and others not at all—to his childhood spent between two households. His mother instilled hardcore discipline, while his father taught him irreverence. This combination of structure and willingness to challenge norms created a unique and effective leadership style.

Secure a Standing Reservation at a Top Restaurant to Hack Executive Networking

By establishing a standing weekly reservation at a highly sought-after Chicago steakhouse, Jubin created a powerful networking asset.
