Emerald Harbor Software Ltd

Dublin

European fintechs and marketplaces keep bolting their checkout onto payment infrastructure that was built for the company that built it, not for the ten companies that came after. Our developer-first payment orchestration APIs are the alternative. About 18 of us work out of Dublin and remote, wiring up card networks, local payment methods and reconciliation logic so our customers' engineers do not have to. We are small, profitable-adjacent, and still led by our two co-founders.
