Manager Business Systems & Data
sinsou (formerly Inteqrate) helps us to set up (and optimise) multiple integrations via the Alumio Platform. In addition to implementation, they also trained us so that we can now do this (partly) ourselves. We find sinsou to be a very flexible, hands-on organisation with a wealth of knowledge and expertise in integrations and the Alumio platform. They really stand out in terms of the speed with which they deliver, respond, and their pleasant, direct contact.
unifying a fragmented IT landscape with scalable integration
Morssinkhof Groep, a Dutch family of companies active in civil engineering, paving, and garden products, struggled with a fragmented application landscape. Sinsou introduced a centralised iPaaS framework that created full visibility, sped up integration delivery, and prepared the business for future digital expansion.
