SiftHub's AI assistant integrates with various information sources and is available as a bot on Slack and Microsoft Teams, a Microsoft add-in, a Chrome plugin, and a web app. The company plans to use the funding to expand its R&D team, improve its product, and prepare for a full launch later this year. SiftHub is targeting B2B companies selling to mid-market and enterprise customers with revenues between $50 million and $500 million.
