The team behind Koi Studios

Andrea Nguyen
Co-founder
Andrea began her career as an in-house designer, but dreamed of building something of her own, shaped around the things that truly matter: meaningful products and relationships. A logical thinker at heart, she leads client projects by bringing clarity to complex challenges and helping teams build with purpose. In between projects, Andrea loves to travel, bake, and run to stay inspired and grounded.

Anyi Sun
Co-founder
Trained in psychology, Anyi loves finding patterns in behavior and creating defining moments. Because she enjoys building Excel models and pitching clients as much as she enjoys designing experiences, she currently focuses on Koi's business development, operations, and marketing. Anyi hopes you will run into her in a dance studio, or perhaps in a grocery store in a foreign country.

Nikita Rao
Product designer
With a background in fast-moving startups, Nikita is working on slowing things down - asking the right questions, diving into the details, and designing for sustainable impact. After hours, you can find her speed-walking through her neighborhood, solving crosswords on the subway, or dissecting a podcast with friends.

Neha Singh
Product designer
Full time product designer and self proclaimed over-thinker, Neha digs into why people behave the way they do and strives to build products that meet them where they are: complex, wonderful and human. When the laptop closes, this curiosity follows her into everything else she does, whether that's in the art she makes, the books she reaches for, or the time she spends with loved ones.

Matt Tomko
Product designer
Fascinated with design for as long as he can remember, Matt argues his career began at age 8 when he started sketching smartphone UIs on graph paper. Now deep into his official design career, he’s still just as fascinated by every new user he gets to research, test, and design for. When he isn’t designing, he also writes, plays, and produces music.

Diane Tsai
Product designer
Diane has always been guided by a genuine curiosity about people and the choices they make. With a background in journalism and documentary filmmaking, she brings a deep appreciation for critical thinking and storytelling in design. Outside of work, she's usually thinking about tennis, skiing, or what to cook on her next camping trip.
