About Us

We Believe in the Art of the Possible

UpTop is a premier user experience strategy, product design, and software development company. Our mission is to help businesses expand their reach, seize market opportunities, and improve efficiencies through exceptional digital experiences. 
In the year 2000, John Sloat co-founded his first digital development company, Peak Systems. Over the years, various projects led him to realize the need for developers and designers who could scale and build things efficiently. The ever-changing world we live in and the user experience humans have with technology inspired John in 2013 to acquire a user experience agency, Produxs, to create the team that you now know as UpTop. On May 1st, 2024, UpTop was acquired by Craig Nishizaki and Michael Woo, long-time members of our team. After 24 years of remarkable leadership under John Sloat, Craig and Mike have stepped into their new roles as owners, bringing over a decade of experience and a strong commitment to innovation. 
We remain dedicated to delivering outstanding customer service, high-quality work, and lasting value to our customers. We hope that you will be an integral part of our story that we are building together.
