Here's the tl;dr:

This is Rise

We set out to build a company that helps teams make the most of their time. Why? Because time is the most valuable asset we can spend only once. Becoming more aware of the fact that we have limited time is one of our key beliefs. And, not coincidentally, the central point in Rick’s bestselling book.

There are thousands of books and apps that promise more focus and productivity. A lot of them require a healthy dose of discipline. You might be someone who can do that, but most in your team might not. We made it our goal to build a tool that solves a problem instead of yet another complicated workflow to adopt.

From the outset we knew we wanted to build something to help find time for what matters most. Our research confirmed this: most teams know what’s important, they just don’t have the time. Schedules are packed and distractions everywhere. And because everyone has different working schedules – something that’s enlarged since the pandemic – it’s impossible to be mindful of everyones preferences. So we opt for the very next empty spot we can find.

It does not matter how empathetic you are as a leader or co-worker, you simply don't have the time to make it work for everyone.

So when we started building the first version of Rise in May 2021, we set out to fix this. Rise is a webbased calendar that sits on top of the Google Calendar API, so there's no signup or data migration required. We believe building a new client is crucial to drastically improve the UX for scheduling. It's also a differentiator that we believe will boost adoption. Finally: by building our own client it's easier to expand to include other services than if we would build a plugin specifically for Google Calendar.

With the first version of this scheduler ready for us to try, we figured we wanted a way to let teams experience the value of Rise without actually using Rise. To do that we built a feature we called Rise Report. With a single Google login, we analyze all calendars of a team and (virtually) reschedule as many internal events we can find using our scheduler. Before and after we measure time to focus (at least 120 mins of uninterrupted time) and fragmented time (the pockets of time shorter than 120 mins).


The results absolutely blew us away. Without changing how many meetings teams have, we estimate that Rise can get back hundreds of hours to focus every week. There's even more potential, since the scheduler is quite conservative: we skip events that are long, with external people or are overlapping other events, for example. So far we ran the reports for about 30 different companies, and here are some results:

Focustime won per week
26 hours
100 hours
48 hours
15 hours
45 hours
304 hours



The Rise web app is written in TypeScript using React and Mobx. It is using websockets to receive real-times updates from the backend. We are looking for a product engineer that works on all of it, but primarily focusses on building a fantastic user experience.

What you'll be working on

You'll focus on building new features and enhancing user experience in our calendar product. Some examples:

  • Implementing delightful small animations that help our users orient and get things done
  • Researching and implementing features that help users save time when using the product
  • Implementing accessibility features, like keyboard handling and shortcuts
  • Improving and expanding the Rise onboarding flow that helps new users and teams get started

What our ideal candidate looks like 💅

  • Extensive experience with Javascript and/or Typescript
  • Extensive experience with CSS
  • Extensive experience with React and/or Angular
  • Cares a lot about high quality, readable, structured code. Advocates best practices and architecture patterns. Is able to make trade-offs between extensibility, optimization and execution speed. Empowers others by reviewing code.
  • Proficient with different types of testing (integration, unit, stress, etc)
  • Has a habit of being paranoid about security and privacy (input validation, network encryption, authentication, authorization)
  • Is autonomous, able to independently pick up tasks and full projects and work through them end-to-end
  • Is product and user minded: is always focused on how their work will impact or optimize the experience of Rise users

We realize that as a founding team we're from similar backgrounds, that we have unconscious biasses and that we have work to do here. This is why we explicitly want to invite and encourage people from underrepresented groups to apply.

Interested and ready to Rise? We'd love to jump on a call with you. Email or @wspruijt at Twitter (DM's are open).
