Why Miru exists
We built Miru because billing by the hour should not depend on brittle spreadsheets.
"We bill clients across time zones and currencies. We needed tracking, invoicing, expenses, reports, and payments in one product. We did not need another enterprise-priced SaaS seat tax."
Vipul A M
Co-founder, Saeloun and creator of Miru
