What we believe
OUR VISION
Business growth
with time, health
and profit intact.
We work towards a future where business owners, teams and customers can all thrive. Rather than adding more working hours, we seek results through better systems and ways to make each effort go further.
The idea behind our name
ISSEKI OKUCHO takes the Japanese expression for “two birds with one stone” further. It reflects our belief that building systems and organizations allows us to create value beyond the limits of one person’s time.
Six principles
that guide our work.
- 01
Create multiple outcomes from a single action
- 02
Solve problems through systems and structure
- 03
Design work that can run without depending on one person
- 04
Use numbers to guide decisions
- 05
Keep things simple and repeatable
- 06
Consider time, profit and health, as well as revenue
