Group facts — not live metrics.
Para Investments LLC is the parent company; its subsidiary is Horizon Services LLC. Its subsidiary owns and operates Sentinel, Nova Horizon and PrintDeck. The parent directly owns HomeServ, TradeLoom, GigHound, Coastal Serenity, TradeFlows product, TradeFlows Guides & Lab and MirrorTape.
Ownership, operation and development are different jobs, and we name them separately — including where a product was built by a different group company than the one that owns it. Where a fact is not confirmed, this site says so instead of guessing.
