Reactiv, a Toronto startup that builds mobile shopping apps for retailers, has acquired Kin Commerce, a New York competitor, BetaKit reported on October 6, 2026. The deal closed in early September and was paid in cash up front. Reactiv did not disclose the price.
Reactiv took over Kin's technology, intellectual property and customer contracts, which include footwear brand Steve Madden and apparel brand Chubbies. Only one Kin engineer joined Reactiv, bringing its headcount to 31. The rest of Kin's team, including its leaders, is moving on to start a new AI marketing company, which is what made Kin available.
Reactiv will keep running Kin as a separate product through Black Friday in November and then look at combining the two platforms.
What Kin built
Kin was founded in 2022 by former Meta employees. Like Reactiv, it lets e-commerce brands launch their own native mobile shopping apps. Its Shopify App Store listing, which went live in January 2023, describes a platform combining content, community and commerce, with a personalized home screen, shoppable video and a community forum.
Reactiv co-founder and COO Zack Elias told BetaKit that Kin's strength was its social features: apps built on it can show shoppers personalized "For You" pages, host forums and pull in a brand's Instagram posts. Reactiv plans to move those features into its own platform over time.
“[Acquiring Kin] definitely wasn't in my 2026 bingo card; I think part of it was kind of opportunistic.”
Why Reactiv is buying
Elias described the deal as unplanned. Acquiring Kin "definitely wasn't in my 2026 bingo card; I think part of it was kind of opportunistic," he told BetaKit.
The main draw was Kin's customer list. Elias said the acquisition "was a growth anchor for us, especially some of those strategic logos," citing Kin's work powering Steve Madden's global stores. Reactiv is also preparing apps for Canadian bookseller Indigo and footwear retailer Browns Shoes, and has been signing professional sports teams.
Elias said large brands are moving away from custom-built websites and apps toward commerce platforms with a lower total cost of ownership, pointing to Reitmans and Canada Goose, which both recently moved to Shopify. He said no retailer wants to change its systems before Black Friday, which he called the e-commerce world's "Super Bowl," which is why the merger of the two products will wait until after the holiday rush.
The founders and the funding
Reactiv was founded in 2023 by former Shopify employees, including Zack Elias and Ross Correia. It came out of stealth in October 2024 with a $5 million seed round led by Bonfire Ventures, with Foxe Capital, Anthemis, Daher Capital and Alumni Ventures taking part, according to Fortune. Its best-known product is Clips, which lets a shopper open part of a retailer's app straight from an ad without installing it.
BetaKit reported that Reactiv closed a previously undisclosed seed extension of $8.5 million Canadian (about $6 million) earlier in 2026, bringing its total outside funding to about $12 million.
Kin's funding history and its founders' names were not reported, and neither company said how much Kin had raised.
What happens to customers
Kin's retail customers keep using the Kin product for now, with Reactiv now running it. After Black Friday, Reactiv plans to decide how to bring the two platforms together, with Kin's social features expected to end up inside Reactiv's own app builder.
The deal did not include Kin's leadership, so customer support and development now sit with Reactiv's team in Toronto.
A crowded market for branded shopping apps
Reactiv and Kin both sold to retailers that want a native mobile app without building one from scratch, and Kin distributed through Shopify's app store. By buying a competitor whose team was leaving anyway, Reactiv picked up a set of well-known brand clients for an undisclosed cash payment and a single new hire, at a time when, according to Elias, more big brands are looking for cheaper alternatives to custom builds.
