First Subway Campaign

Our first NYC subway ads are a huge bet. At the time, very few tech companies advertise this way. People start sending us photos and saying, “I saw you on the train!” We have a goal to put ourselves on the map. It works.


Investing in service

Customer Success at Justworks starts to grow and evolve as a cornerstone of what we do. Admittedly, we're a bit obsessed with the entrepreneurs and teams we get to help everyday.

20+ Employees

People are sharing desks at this point. Finally, we move to our second office — 5,500 square feet at 29 E 19th St, which feels huge! It's an exciting time.

First company retreat

Almost two years in, we embark on Justworks’ first retreat to the wilderness. It becomes one of our favorite traditions and continues to this day.

Every month, employees pair off with a new colleague to grab lunch. The tradition, which continues today, helps keep the company feeling close-knit as we grow.

Updating our brand

Until now, there hasn't been time for an extensive design exploration. The team heads to an off-site to finish up and launch the redesign of our visual brand.

tool icon

Series A Funding of $6M

We set out to execute on growing our salesforce and investing in marketing, software development, and proving our unit economics to partners and investors.


Testing the pilot

We never call our beta a beta. We call it a pilot because there’s no room for error with what businesses do in Justworks. We build a lean UI and deepen functionality based on what people demonstrate real demand for. This approach allows us to scale the product efficiently.

Our first real office

At 125 Maiden Lane, the carpet is still damp from Hurricane Sandy, which had flooded the area six months prior. Unfortunately, Ikea is out of regular desks so we're stuck with child-sized versions for some time. We couldn't be happier. Finally, we have a home.

Defining our values

The team gathers for an off-site at Isaac’s apartment to talk about what sort of qualities should define Justworks as it grows. We discuss the attributes of people and leaders we admire and respect. The outlines of COGIS take shape.

tool icon

First employees start

The attributes of our team today — kind, smart, hard-working — exist in Justworks' first hires (and Milo, Isaac's dog). We're an eclectic group, but have some common threads. Everyone wants to do something great and to be proud of what we are building.

tool icon

Seed funding of $1M

Friends cover enough to hire Justworks' first engineers and get the company off the ground, with Isaac raising the rest from outside investors in parallel.


New Work City

We start working out of a non-profit coworking space called New Work City, which happens to become Justworks' very first customer. The Blue Man Group rehearses on the floor above us. Yes, it gets loud.

The platform is born

It all starts with the company directory screen — if you know who is who, you can go from there to complete other tasks. Isaac works on coding the payroll engine and integrating income tax calculations next.

tool icon

Clockwork, Inc

Isaac Oates founds Justworks as Clockwork, Inc. The original name, which implies reliability, ends up being a little too reminiscent of "A Clockwork Orange." Plus, clockwork.com is taken. Voila, Justworks.
