Atmosphere is the world's leading streaming TV service for businesses, offering original, audio-optional TV channels. There is a channel for every business and mood. Atmosphere's TV channels fill the void for businesses in a world dominated by linear cable TV suited for at-home viewing. No cable carrier has addressed the need for TV programming that doesn't require audio or the love of sports to be enjoyed. Atmosphere's founders recognized that TV for business was broken and they set out to fix it. Closed-captioned talking heads, news and reality TV on mute is no way to watch TV in businesses. So Atmosphere set off to conquer an entirely new class of TV programming: audio-optional streaming TV. Businesses can now run their own marketing promotions both within their venues and outside of them by utilizing Atmosphere Ads, and keep the content fresh with custom playlists! Atmosphere was incubated under Chive Media Group and spun out in 2019.

Stack Overflow is a technology knowledge platform headquartered in New York City, best known for its public question-and-answer community that has served roughly 100 million monthly active users over 15 years. The company was founded by Joel Spolsky and Jeff Atwood and is led by CEO Prashanth Chandrasekar, who joined in 2019 and has overseen a strategic pivot from an advertising and job-listings business to a subscription SaaS model. The SaaS product, Stack Overflow for Teams, launched in late 2018 with Microsoft as its first customer. It gives companies a private, internal version of the Stack Overflow platform for proprietary knowledge management. As of early 2024 the company counts 15,000 customers on the Teams product, charges approximately $18 to $19 per seat per month at the enterprise tier, and counts Bloomberg and Siemens among its named accounts. Revenue has crossed $100 million annually, with Chandrasekar confirming the figure is above $125 million at a March 2024 event. Recurring subscription revenue now accounts for close to 70 percent of total company revenue, up from essentially zero when Chandrasekar joined. The company has also launched an Overflow API program to license its content to large AI model providers, with Google Gemini as the first announced partner.
