Startups Don’t Scale Without Real Culture

In this episode, Brittany Blumenthal, VP of People at HiddenLayer, shares how early-stage startups can intentionally define and evolve their culture. She breaks down the challenges of working with strong founder imprints, the importance of documenting culture as a living contract, and how to build feedback loops that go both ways. If you're scaling a team and want culture to grow with it, this episode offers tactical insight and hard-earned lessons.

🔑 Key Takeaways:

1. Culture Starts With the Founder’s Imprint
   Founders often shape company culture unintentionally. People leaders must help them surface, reflect, and intentionally evolve that foundation.

2. Write It Down—Make Culture a Living Document
   You can't scale what’s vague. Culture should be defined, documented, and expected to evolve as the company grows.

3. Bi-Directional Feedback Is a Culture Keystone
   True culture thrives when feedback flows in both directions and employees feel safe to share how the company is doing—not just how they are doing.

4. You Have to Slow the Founder Down
   In early-stage companies, a big part of the People leader’s job is convincing founders to pause and co-invest in culture before it becomes reactive.
