This will be my last day as a Co-Founder of @OpenPhone. Because starting today, OpenPhone is rebranding to Quo. Oh, and we've raised $105 million in growth financing to help businesses never lose a customer again. You probably have a lot of questions, so let me break down what's happening: 1) $105 million in growth financing We have raised $105 million in growth financing led by @generalcatalyst's Customer Value Fund and with participation of existing investors @craft_ventures, @slow, @GarageCapital, and @ycombinator. This funding gives us the resources to invest further in what our customers love most and to help us reach more businesses. 2) Why OpenPhone is becoming Quo When @mahyarraissi and I started OpenPhone in 2018, our mission wasn't just to help businesses make calls and send messages—it was to help them build stronger customer relationships so they could grow faster. You can even see in our YC application we described ourselves as "phone meets CRM." But as the years went by, we realized the name "OpenPhone" only tells part of our story. While it worked when we were focused only on the business phone, it started limiting where our customers needed us to go. With Quo as our name, we can finally tell the full story. Think of Quo as your business's customer hub, with phone at the center. It's how you win customers and keep them happy. Although our name has changed, what matters to us hasn’t. We are still obsessed with building great products and helping our customers never miss an opportunity. 3) What's changing with the product We're launching major upgrades to our voice AI agent Sona based on everything we've learned from our customers: - You can now start using Sona for free on all plans with our new tiered, usage-based model - Every customer gets 10 free Sona calls per month - Sona can now handle more sophisticated scenarios and can be trained on custom jobs - It can also now transfer calls to a human if needed -- To our incredible customers—we simply wouldn't be here without you. Thank you for trusting us to power your customer communications. Thank you to our team for the care and energy you’ve poured into making this milestone happen. And to our investors—thank you for believing in our vision.
