Careers

Untangling "we can't get through" with the power of words. We are hiring people who face products and customers with honesty.

Culture

How we work

Accuracy over speed. Sincerity over flash.

Our products run in the front line of customer-facing support, where they are effectively the face of our clients' companies. That is why we choose reliability over flashy releases. We take pride in quality we promised and kept — and when something breaks, the whole company faces the post-mortem together.

We work from our Toranomon office three days a week, because cross-discipline conversation matters here. Engineers join customer success calls; support staff sit in product meetings. The words we hear in the field come straight back into the product — that is the loop we run on.

See the field

Every employee visits a client's support center twice a year. We learn the problem next to the people who live it, not through a screen.

Write clearly

Internal documents are judged on whether anyone can read them without misunderstanding. Careful writing is the foundation of a careful product.

Rest properly

Quality of response starts with the state of the person. Paid-leave usage exceeds 80%, with company-wide summer and year-end breaks plus refresh leave.
