About Jemma Lee

You're building something real. Your people structure should be too.

If you're leading a company between 50 and 150 people, you're probably feeling it: the informal ways of working that got you here are creating friction. Managers are struggling without a framework. Performance conversations are inconsistent or avoided. The culture you built when you were small is starting to drift — not because your people are wrong, but because the structure hasn't caught up with where you're going.

That's not a failure of leadership. It's the predictable challenge of growth. And it's exactly the moment I built PeOrient to address.

Here's the experience I bring to your organization.

I'm the founder of PeOrient and a People Strategy Advisor with over a decade of experience designing performance management, leadership development, and talent systems inside large, complex organizations.

My work is grounded in industrial-organizational psychology — the applied science of how people, teams, and systems actually function at work. That foundation shapes how I approach every engagement: evidence-based, focused on what actually changes behavior, and skeptical of HR programs that look good on paper but don't hold up under real organizational pressure.

Before founding PeOrient, I spent my career in HR centers of excellence at enterprise-level organizations. That experience taught me something more valuable than any framework: I've seen exactly what happens when people infrastructure gets over-engineered, overcomplicated, and disconnected from how a business actually runs.

I know what works at scale. More importantly for you — I know what to leave out.

What I bring to growth-stage companies isn't enterprise HR. It's the judgment to know what you actually need at your stage, what will slow you down, and how to build people systems that work right now — not systems designed for a company ten times your size.

I founded PeOrient to bring that same depth of thinking to growth-stage companies. Founders and leadership teams who are serious about building something durable, and who need a people partner with real operating experience — not just a framework and a slide deck.

I hold an M.A. in Industrial-Organizational Psychology with a specialization in organizational effectiveness. I'm bilingual in English and Korean, and work with both U.S.-based growth-stage companies and Korean organizations building their people function in the American market.

Let's build the people foundation your company deserves.

If you're ready to stop managing people problems reactively and start building the systems that let your organization grow with clarity — I'd like to talk.
