It all started 10 years ago when we asked ourselves: is anyone in healthcare thinking about patients? We jumped in and we empowered patients by giving them access to <strong>leave and read reviews about their visit</strong>. We then provided doctors with the technology to <strong>manage bookings easily and save time</strong>, so they could devote themselves to what they always wanted: treating patients. And today is the day in which we ask you: wanna join us in the next step of making the healthcare experience more human?</p><p><strong>Docplanner at scale</strong></p><p>We are leaders in <strong>13 countries</strong> so far, and more than <strong>90 million patients</strong> trust us every month. <strong>280.000 specialists</strong> believe in us and our product, and so do<strong> leading venture capital</strong> funds such as Point Nine Capital, Goldman Sachs Asset Management, and One Peak Partners. And yet, employing over <strong>2.900 people all over the globe</strong>, we managed to keep the startup mindset we started with over 10 years ago.</p><p><strong>How does Docplanner Tech fit here?</strong></p><p>At <a href="https://docplanner.tech/">Docplanner Tech</a> we are a diverse group of <strong>~325 people</strong> working in teams that include engineers, designers, product managers, data and research.
