Our values are our foundation.
The faster we fail, the faster we can get closer to a solution! Failing fast does not mean
that we do not try to succeed—quite the opposite. It means that we do not let the fear of
failure keep us from trying our best.
Each and every employee at HireRoo takes pride in the work they do. We love what we make
and the creative process in general. HireRoo employees always strive for excellence.
It is not as individuals but as a team that we can achieve our greatest potential. At HireRoo,
we play, work, win, fail, and succeed together. The ability to trust and be trusted by your
team members is paramount.
HireRoo’s values in action
● We have many mechanisms in place for
quickly reflecting on past actions taken.
● Even when HireRoo had no more than 10 members in total, everyone pulled together to
aim high and achieve the lofty goal of an advent calendar.
At our monthly “In-Person All-Hands,” we recognize members who have demonstrated or embodied
our values with the Fail Fast Award and the Aim High Award.
This is a screenshot of the moment we decided to do the advent calendar.
This is an example of a meeting where we reflected on the
● Work hours: Flex (core time is 12:00–17:00)

Message from the CEO
I like to say that while good products sell, great products that provide value will always
sell, and at the core of these products are the engineers who make them.
Together with my colleagues, I founded HireRoo with the dream of creating a world in
which the skills of engineers are fairly evaluated and Japan is once again at the top of
I truly believe that great products will always sell. But creating a great product in the
first place takes more than just people who make things—we also need people who sell
things, people who know how to optimize value, people who are good at networking,
and many, many more!
This business is where I choose to dedicate my life and to accomplish HireRoo’s
mission we need you!
So come take on the challenge—join HireRoo and let’s aim high together!
