SIG Innovation Accelerator


The SIG Innovation Accelerator (SIA) combines the collective knowledge and strengths of SIG’s 250 large buy-side companies to create new products and evaluate meritorious mid-stage products in the Source to Pay (S2P) space.  SIA is driven by its Leadership Council, comprised of 24 member CPOs.  

To help ensure a robust pipeline of innovative products, SIA also works with select mid-stage and earlier-stage providers to assist them in product development and market penetration.
