Rebuy, an omnichannel personalization platform, has raised $4.4 million in growth capital from Peterson Ventures and Sidekick Partners.

Founded by two developers-brothers in 2017, Rebuy empowers Shopify stores of all sizes to offer personalized shopping experiences designed to increase conversions, boost average order value (AOV), and retain more customers using data-driven upsells, cross-sells, and post-purchase follow-ups.
