People who no longer have to search work faster and decide better. ### Less time searching Instead of going drive by drive and mailbox by mailbox, one query returns every relevant result. ### Knowledge stays usable Project files, contracts and correspondence stay findable – even after the people responsible have moved on. ### Better decisions When you find all the facts, you decide on complete information – in sales, purchasing or legal. ## Two ways to enterprise search Lookeen comes as a desktop app for workplaces and as a central server for the whole company. ### Lookeen Desktop Each workplace indexes its own data: Outlook, Exchange, Microsoft 365, local and network drives.
