Reliability Score Feature to Improve Male User Engagement on Bumble
A reliability score for Bumble that rewards people who actually reply, aimed at male churn
✳The problem they went after
Single male users on Bumble deal with low match rates, slow or absent responses, and conversations that die right after the opener. Because women have to initiate, the platform's gender dynamics create a structural imbalance that lowers engagement quality for men and drives early churn when matches never become conversations.
✳What they actually did
The Reliability Score reads behavioural signals such as response consistency, conversation completion and interaction quality, then shows a score on male profiles with a breakdown and suggestions for improving it. ICE ranked it first out of ten brainstormed ideas, mainly because it changes incentives without requiring a structural change to how the platform works. The experiment targets at least a twelve percent lift in meaningful engagement, defined as matches reaching three to five message exchanges within seven days.
✳What you can take from it
Worth stealing
- Meaningful engagement defined as three to five exchanges in seven days
- ICE scoring across ten brainstormed solutions
- Guardrails on female retention and complaint rates
- Named pitfalls: score anxiety, unfair penalties, perceived judgement

Shipping a visible user score and needing to think through how people will game or resent it
The transferable bitGuardrails watch female seven-day retention and complaint rates so a fix for one side is not paid for by the other, and the pitfall analysis names score-induced anxiety, unfair penalties for niche usage patterns, and the score reading as judgement rather than motivation. That is unusually careful risk thinking for a single feature.
