Our Story
Founded in 2018
Sirona was started to reimagine how radiology is practiced in the AI-age.
$100m raised
Sirona is built alongside an incredible group of design partners and practices. These practices and physicians believed in Sirona from the idea stage, and we wouldn't be here without them.
RadOSTM Launched in 2023
In November 2023, Sirona launched RadOSTM publicly. In the 24 months that followed, Sirona grew usage by more than 100x and became the largest single instance of a PACS product in history.
Our values
Hospitality first
We want to be more than the best radiology IT vendor, we want to be our customers’ favorite business to work with.
Operate with humility
At Sirona, everything we do is a team sport. We take pride in our collective work, while each of us operates with humility and purpose. The physicians we serve are the true stars — we’re here to help them shine.
Be authentic
Authenticity is the foundation of trust, and our customers’ trust is the foundation of our business. As a result, we don’t censor or stylize ourselves - we are our most authentic selves, always.
Care for others
For everyone at Sirona, being of service and caring for each other, our partners, and, most importantly, the patients we touch, is what brings us the most joy in life.
Unapologetically ambitious
The first industry reporters called Sirona “irrationally ambitious.” They were right - and we built Sirona anyways. At Sirona, we build what radiology needs most - solutions, not stop-gaps.
Leadership
Sirona’s leadership team directly led Powerscribe360 from inception to market dominance, McKesson PACS from two installations to a 25% market share, and the engineering of Amazon’s logistics engine from pre-IPO to post-IPO. Additionally, they oversaw commercialization at AIDoc from $20 million to $50 million, among other notable achievements.
