ClassDojo raises $125 million in Series D

We transformed a decade of grassroots growth into a valuation of over $1.2 billion

Remote first

Our team hails from all around the globe, and we like it that way.

As a remote team, we are spread from Canada to Argentina, working in U.S. time zones. We also understand the value of working and building relationships face to face, so we make an effort to get together a couple of times a year. Our interview process is fully remote, too; we'll start with a quick call to get to know each other before moving onto a coding challenge and, if things go well, a virtual onsite.

Dojo Islands is the first and largest digital playground of its kind. Our culture makes it possible.

How we roll

Behind the scenes is a hardworking team with strong principles that evolve for every phase along the way.

Collaboration > Parallelism
Collaboration > Parallelism

Two brains (or three, or four) are better than one, so we tackle almost everything as a team. We ask for help when we need it, but we also take the responsibility to proactively ask each other how we can offer support. We’re always unblocking each other.

Trust > Control
Trust > Control

Everyone on the team has the same goals and world-class expertise, so there’s no micromanagement here—just a supportive community backing you up as you own your projects.

Candor > Harmony
Candor > Harmony

Serious teamwork requires serious communication skills, so we always say the hard things with respect and kindness. Anything else cheats everyone out of growth opportunities.

Finishing > Starting
Finishing > Starting

Multitasking is a great recipe for iffy work, so we do just a few things at a time with extra precision and urgency. When we say “finished,” we mean “in users’ hands.” It’s a high bar, but intense focus makes it possible.

Humanity > Heroism
Humanity > Heroism

We know that downtime isn’t an indulgence—it’s a necessity. We take rest seriously because it increases productivity, and we minimize interruptions that can throw workflows out of whack.

Continuous Improvement > Continuous Production
Continuous Improvement > Continuous Production

We’re constantly evaluating not just our product, but our productivity: we regularly schedule retrospectives and post mortems to find better ways forward. By investing in ourselves, we’re planting the seeds for better work and better work-life balance.

Rafael ChitiSoftware Engineer, Barcelona
“The level of trust, autonomy and critical thinking I see at ClassDojo is like nothing I've experienced before.”
Puri Bey
Puri BeyFull-stack Engineer, Argentina
“I love how passionate everyone is and how I'm always learning new things, but most of all, I love our work environment. People here care about your mental state and encourage you to keep it healthy. The bar is high, but it’s always a lot of fun. ClassDojo has improved me as an engineer and as a professional in so many ways.”
Noah Wiener
Noah WienerSoftware Engineer, USA
“There's a deep focus on ownership, emphasis on the full side of full-stack, and readiness to empower engineers to learn new things. Ownership focus spans an incredible range—from owning features with sophisticated & thoughtful monitoring to the ability to own technical realms. It is very easy & encouraged for an engineer to choose an area to level up in, and make company-wide improvements in that space.”

Top questions

What's our stack?

We use TypeScript with Node.js on the back-end and React on the front-end. It's all hosted on AWS, using Terraform, Nomad, and Consul, with MySQL and MongoDB as our databases. Our iOS app is Swift, and our Android app is a hybrid mobile web app.

What sets us apart from most engineering organizations?

We are a high-trust, low-control engineering environment with a heavy focus on automation, tests, production monitoring and quality in general.
We have a low reliance on human inspection: pull requests are neither mandatory nor blocking in most cases, and we don't employ manual testers ("QA") at the company at all. We hire people who care about quality and collaboration, and we don't want to police it.
We are probably more collaborative than most places, often pair programming or mob programming (but not all the time). Teams and individual engineers have a lot of autonomy in technical decision-making.

Do we follow a particular software development methodology?

Our approach is mostly inspired by Kanban: we don't do sprints or traditional estimates, but we do have many familiar practices such as standups, weekly planning, and retrospectives. We pursue Continuous Development very aggressively, deploying many times per day in almost all codebases.

Do we have on-call?

Yes, we do—but it's straight forward. The rotation currently puts each engineer on-call every 12 weeks or so. We always prioritize fixing issues that occur during off-hours higher than everything else so they don't keep interrupting our lives.

How we work

Our Approach to Mob Programming
Our Approach to Mob Programming
Our teams at ClassDojo have the freedom to choose how they want to work. Many of our teams have started spending a few hours each day mobbing because we've found it to be an effective form of collaboration. Here's how we do it!

P1, P2,...P5 is a broken system: here's what we do instead
Software developers need to prioritize bugs when they are discovered, and most do this with an ordered priority scheme. Tracking tools like Jira provide a column on each ticket, and many organizations use numbers, such as P1, P2, P3, P4, and P5.

Why we don't do blocking pull requests
Why we don't do blocking pull requests
One aspect of our workflow that people often find odd or new to them is that we don’t require an up-front code review or pull request with signoff from another engineer before pushing to production. This often comes up in interviews or conversations with engineers who are interested in jobs at ClassDojo, with reactions ranging from curiosity to aversion.
