We started Cmaine to make moving money feel boring.
Founded in Singapore in 2021, Cmaine grew out of a simple frustration: building payments in this region meant stitching together a dozen providers, each with its own quirks.
So we built the layer we wished we'd had — one integration that speaks to every major rail across the region, with the reliability and observability a finance team expects.
Today a team of 60 across Singapore, Kuala Lumpur and Ho Chi Minh City supports companies processing billions in volume every month. We're backed by operators who have built and scaled financial infrastructure before.
We're hiring across engineering, risk and partnerships. If infrastructure that quietly never fails sounds like your kind of work, we'd like to hear from you.
