What stands out

  • Cloud email and email security for companies and local governments, with most revenue coming from monthly subscription fees
  • It outsources product development to partner firms under what it calls a fabless model, and its operating margin reached 42.5% in the year to April 2026
  • In the year to April 2026, its first full year as a listed company, it paid a dividend of 32 yen a share, a payout ratio of 45.5%

What could go wrong

  • Because it develops no products itself, its business depends on its relationships with the partner firms that do the development
  • It carries goodwill from the 2023 buyout, and its listing filing states that an impairment loss could be recorded if profitability falls
  • Revenue is around 4 billion yen, and large IT companies also compete in email and security

About the company

Provides cloud email and email security services to companies and local governments in Japan.

How it makes money

It reports a single segment, but the work splits in two. Security covers email sanitisation and data-leak prevention; communication covers corporate email, business chat and groupware. Most revenue is monthly subscription fees, and at the time of the listing filing the effective churn rate on its cloud services was zero or below, meaning existing customers expanding their use more than offset cancellations. It develops no products in house, outsourcing that to partner firms in what it calls a fabless model, which keeps fixed costs down. Its operating margin was 42.5% in the year to April 2026.

Where growth is meant to come from

For the year to April 2027 the company forecasts revenue of 4.0 billion yen, up 13.5%, and operating profit of 1.8 billion yen, up 20.0%. Its stated approach is a hybrid one, earning steadily in the mature market for corporate email while growing in the expanding market for email security, and it is rolling out AI-based services such as a gateway that detects misaddressed email. In the year to April 2026, its first full year as a listed company, it paid a dividend of 32 yen a share, a payout ratio of 45.5%.
