UpCart and AfterSell are owned by Rokt (common ownership since AfterSell’s 2024 acquisition, which included UpCart). Read both together — the two products received materially different Privacy/Transparency scores despite the shared parent, because the Rokt Thanks finding was traced to AfterSell’s product surface specifically, not UpCart’s. Rebuy and Zipify OCU are both genuinely different kinds of competitors to the UpCart/AfterSell pairing — each is one product covering the same combined ground UpCart+AfterSell cover together, at the cost of usage-based or revenue-share pricing instead of flat.
