Meet Zora Chung | Cofounder & CFO

We had the good fortune of connecting with Zora Chung and we’ve shared our conversation below.

Hi Zora, is your business focused on helping the community? If so, how?
At its core, ReJoule brings greater transparency and higher utilization of batteries. While the innovation is deeply technical, the implications are far-reaching.
Battery health is still one of the biggest uncertainties in the EV ecosystem. When automakers can’t quickly and accurately assess battery condition, it creates bottlenecks in repairs, uncertainty in resale value, and hesitation in the secondary market. That uncertainty costs money and creates waste along the EV value chain.
By making battery diagnostics fast and scalable, we help build trust through data. Better diagnostics mean fewer unnecessary battery replacements and more opportunities for repair and second-life applications. Extending the useful life of batteries reduces waste and maximizes the value of the materials already in circulation.
For ReJoule, social impact isn’t separate from business — it’s embedded in the work. If we can make battery health more transparent, managing aging batteries becomes more economically viable and more resource-efficient — that helps move the entire ecosystem forward.

Alright, so for those in our community who might not be familiar with your business, can you tell us more?
At ReJoule, we help automakers unlock more value from their electric vehicle batteries through fast, accessible diagnostics. In under 10 minutes, our platform can assess battery health — helping reduce repair bottlenecks, manage warranty costs, and bring more transparency to the used EV market. We’re solving a problem most people don’t see, but one with enormous implications.

But building this company has required more than technical innovation. It has required growth — personally and professionally.
The past year, in particular, challenged me in ways I didn’t expect. When you’re leading a company in an industry moving as quickly as EVs, it’s easy to default to working harder. To push longer hours. To try to out-hustle uncertainty. But I’ve learned that effort alone isn’t the answer. Working harder without changing perspective can quickly lead to burnout.
What moved us forward wasn’t just persistence — it was reframing. Listening more closely to our customers. Rethinking assumptions. Being willing to adapt how we tell our story and how we create value. Instead of trying to control every outcome, I’ve learned to focus on what we can control: how we respond, how we show up, and how we support the people building alongside us.
I’m most proud that through all of it, we’ve stayed grounded in our mission — making battery testing simpler, more accessible, and more scalable.
If there’s one thing I want the world to know about ReJoule, it’s that innovation isn’t just about technology. It’s about resilience, clarity, and the discipline to evolve.

If you had a friend visiting you, what are some of the local spots you’d want to take them around to?
We’d start with what makes LA feel like LA — the ocean. One day would be dedicated to the beach: an early yoga session by the water, followed by brunch at the rooftop at Hotel Erwin. There’s nothing like a meal with a beach breeze and a view of the coastline. After that, we’d walk along the Venice Beach Boardwalk — chaotic, creative, and quintessentially LA.
During the week, I’d make sure we balance the sunshine with some culture. A visit to The Getty Center or Getty Villa is always grounding — beautiful architecture, thoughtful exhibits, and some of the best views in the city. Another day, we’d head to Exposition Park, grab takeout from Holbox, and picnic near the Exposition Park Rose Garden.
We’d wander the farmers markets in Brentwood and Santa Monica for fresh food and flowers, then spend an evening strolling Abbot Kinney Boulevard for dinner and people-watching. And of course, we’d dedicate at least one night to exploring West Hollywood and Beverly Hills — some shopping, great restaurants, and a fun cocktail — all with a little glam.
Last but not least, a stroll along Sawtelle. I may even pick up some nigiri at the Nijiya market to make a homemade sushi dinner for a change of pace.

The Shoutout series is all about recognizing that our success and where we are in life is at least somewhat thanks to the efforts, support, mentorship, love and encouragement of others. So is there someone that you want to dedicate your shoutout to?
This past year has been tough. My family, friends, investors, and team have been a steady source of support, and I don’t take that for granted. But in this Shoutout, I’d like to recognize the wider community of allies who made an unexpected difference.
The rapid pace of change and uncertainty forced me to rethink how I lead and grow my business. I had to learn new skills, pursue unfamiliar opportunities, and make decisions that stretched me beyond my comfort zone. In that process, I found support in new connections who quickly became champions. What struck me most was how universal it felt. Our circumstances were different, but the stress and pressure we all felt were shared.
I want to thank the people who go out of their way to help others — especially those they may barely know. That kind of support reminded me that while we can’t control what happens in the world, we choose how we show up. And sometimes, that choice has a bigger impact than we realize.
