Harmony gives every employee an always-on expert for workplace support, embedded directly in the tools they already use. Deployed inside Slack and Microsoft Teams, Harmonys AI agents draw on a context graph connecting each employees identity, devices, applications, and work history, resolving requests across IT, HR, finance, procurement, legal, and other enterprise service functions. With more than 100 prebuilt agents that deploy in days, not months, and a 70% no-touch resolution rate, Harmony removes the manual work from enterprise service while enabling internal teams to focus on the problems that require human judgment and expertise. Built for IT and HR teams, Harmony is redefining how employee support is delivered.

Our mission is to make the best skincare accessible to as many people as possible with prestige-quality products for under $20. Bubble. Face the Day. Gentle Formulas, Fierce Results Our products are not meant to work instantly. Instead, our gentle formulas are specifically designed to provide consistent, long-lasting results—because slow and steady wins the face. Lower Prices for Prestige Quality We strive to create premium products that deliver better results than prestige products that cost 10x as much as ours—because we want to make the best skincare accessible to as many people as possible. Developed with dermatologists Our formulas are developed with the help and guidance of our advisory team of dermatologists to ensure our products lead the industry in efficacy, safety, and quality. Co-Created with Community Our in-house team of product developers works with our community of Bubble Ambassadors to concept, formulate, and test every product from scratch to make sure they’re super effective. Safe for All Ages We are committed to crafting formulas that are safe for all faces. Not all of our products are recommended for faces under 14, but many products are specifically approved for all ages.
