Hello, Wix has a new product that's aimed at a more professional clientele called Wix Studio. It's been out for almost a year now. I think it's mainly a competitor to Webflow. I'm building a site in it right now for a client who also uses Hubspot for their CRM/Sales/Marketing. There is no native integration from Hubspot for Wix. There is one from a third party company called SyncSmart, but it is very pricey. My clients are unwilling to pay for that solution, so I am left manually implementing iFrame forms and tracking codes. It's very tedious and restricts the design substantially.
Hubspot offers free integrations for Wordpress, Webflow, and Shopify. I think it's a no-brainer to add a Wix Studio integration, since it will be targeting a lot of the same audience as Webflow, and has a much larger user base than they do. Wix also seems to have an app market and fairly robust CMS, so I don't think this would be a heavy lift for Hubspot developers to make.
