Boomerang

What Boomerang does

Boomerang (legal entity Baydin, Inc.) is a private, bootstrapped email productivity and meeting scheduling software company founded in 2010 and operated remotely with historical roots in Mountain View, California. The company serves individual professionals, small and mid-sized businesses, and enterprise customers through a suite of tools that integrate natively into Gmail, Microsoft Outlook, iOS, and Android environments via browser extensions, Microsoft Add-ins, and native mobile apps. Its core product line includes Boomerang for Gmail, Boomerang for Outlook, Boomerang for iOS, and Boomerang for Android; the January 2025 acquisition of GQueues extended the portfolio into Google Workspace-integrated task management. Boomerang serves more than 2M active customers and has facilitated 500M messages delivered, with a self-reported ~1.5M businesses using the product daily.

The technology platform is built around embedding productivity features directly inside the user's existing email workflow rather than redirecting them to a separate application. Key technical components include the Respondable AI writing assistant (NLP and predictive analytics trained on millions of messages), the patented Magic Live Calendar that embeds real-time availability into emails, Inbox Pause for focused work, Send Later, privacy-respecting read receipts, and a layered meeting scheduling stack comprising Meeting Poll, Bookable Schedule, Suggest Times, and Share Free/Busy. Boomerang holds 7 patents, maintains SOC 2 Type II compliance (since October 2021), and is GDPR compliant.

The business model is subscription-based with a freemium acquisition layer. Revenue is generated through tiered subscription pricing for Gmail and Outlook products on monthly and annual billing cadences; a free Basic tier (now including Meeting Poll) drives product-led adoption through marketplace distribution via Chrome Web Store, Microsoft AppSource, iOS App Store, and Google Play Store. With 19 team members and reported continuous profitability since 2013, Boomerang operates as a lean, founder-controlled, capital-efficient company with no disclosed institutional funding rounds. The customer mix spans individual knowledge workers and small professional services firms up to enterprise logos including Lyft, Twilio, DoorDash, IHG Hotels and Resorts, Keller Williams Realty, Atlassian, and HubSpot.
