VENTURE BEAT - Oct 21 - This is a guest post by entrepreneur Alex Mehr (Zoosk). People’s relationship statuses change, which makes it difficult to keep customers long-term. Zoosk saw an opportunity to overcome the challenge of customer retention, and created a service for people in relationships. Companies must now offer different tools to users at every stage of their romantic journey. Several new services have popped up that offer private social networking for couples. "By expanding our services beyond dating, we’ve been able to create more brand loyalty and have also built stronger relationships with our users", said Alex Mehr.
