SLI's clients include The Warehouse Group, Mitre 10 and London's Harrods department store.
California-based online shoe retailer Footwear Etc has been involved in the testing of SLI's recommendation feature.
"Based on early use of SLI's new Learning Recommendations product, we're already seeing that the feature has improved how customers find products of interest on our site, and we're confident it will have a solid impact on our sales and revenue," said Footwear Etc's Mike Baranov.
SLI, which raised $27 million when it listed on the NZX in May last year, reported a full-year net loss of $2.01 million in August, smaller than the $2.15 million loss it forecast in its initial public offer prospectus.
Ryan said SLI would give an update on its progress in new markets such as Japan when it reported its half-year financial results next week.
The firm's shares, which closed up 1c at $2.51 last night, have gained around 67 per cent since listing.
