Tinder launches Group Hangouts for social dating

Tinder has announced the launch of 'Group Hangouts', a new feature allowing groups of friends to discover, match, and plan activities together. Users create a group by choosing an activity and inviting at least two friends, with a maximum of 15 members. Groups appear in the main card stack where other groups can like them, and mutual likes connect them in a shared chat. Control features include the ability to leave conversations without leaving the group, and block/report functions. The feature is rolling out in phases in the U.S. and select markets. This initiative follows Tinder's earlier 'Double Date' feature and its broader push towards in-person events, as the company aims to re-engage users amidst declining revenue and user numbers.

• Tinder launched 'Group Hangouts' feature on 30 September 2026.
• Feature lets groups of 3-15 friends discover, match, and plan activities.
• Available at top of Tinder's main home screen, rolling out in phases in U.S. and select markets.

Bumble drops women-first messaging rule

Bumble announced that it is removing the long-standing requirement that only women can send the first message in heterosexual matches; now either person in a match can initiate conversation. The app is also extending the response window from 24 to 72 hours. CEO Whitney Wolfe Herd described the change as an evolution of the company's women-first mission. Bumble cited survey data indicating 66% of surveyed women prefer men to send the first message and that a longer reply window improves experience for over half of respondents. The update follows prior relaxations (e.g., 2024’s Opening Moves) and comes as Bumble reports declining revenue — Q2 revenue fell 15.2% year-over-year to $210.5 million — and explores product directions like swipe-free experiences, in-person events, and AI features.

• Bumble changed its matching rules so anyone in a match can send the first message, ending the women-message-first requirement.
• Bumble extended the response window for matches from 24 hours to 72 hours.
• Bumble cited survey data saying 66% of women surveyed prefer men to send the first message; more than half said a longer response window improved their experience.

Bumble pivots to IRL meetups, teases swipe-free future

Bumble announced early success for its new Plans app, which facilitates low-pressure, in-person group meetups, and signaled a strategic shift away from the traditional swipe model. CEO Whitney Wolfe Herd told investors on the company's Q2 earnings call that Plans showed "promising results" and that Bumble will lean more into real-life experiences and a new interaction model to replace the swipe. The company said it will use more AI tools behind the scenes while avoiding an "AI-driven" user experience. Bumble reported Q2 revenue of $210.5 million, down 15.2% year-over-year, and noted concerns about paying-user declines reflected in its Q3 forecast and stock reaction.

• Bumble promoted early success of Plans, an app designed to connect people IRL in low-pressure group settings.
• CEO Whitney Wolfe Herd said Plans showed "promising results" in early tests and the company will lean into real-life experiences.
• Bumble is developing a new interaction model intended to replace the swipe, moving toward a "swipe-free" experience.
