stitch
We stitch data, advertising and marketing technology together to drive measurable business outcomes. Marketing is more complex than it’s ever been The increase in diversity of consumption from fragmented experiences that go across device, browsers, apps and physical experiences are leading to marketing complexity where requirements are outpacing available resource while providing real challenges within the measurement space as well.

E-commerce is growing fast, yet 94% of transactions still happen in the real world. To get full visibility into the customer journey - we need to close the loop with customer data while reducing our reliance on proxy metrics such clicks. Why choose us? At stitch we have over 30 years of combined strategic, technical and implementation experience from global tech companies, agencies and consultancies (such as Facebook, Microsoft, Accenture, Initiative Media, Clemenger & Colenso BBDO) helping brands fully realise the potential of merging strategy, data, advertising and marketing technology to deliver more profitable business outcomes through a transformed customer experience.
