Social Networks have become more media platforms than “social” platforms. They are not designed to make real human connections. Demand for more intimate online places is higher than ever. Communities are in huge demand!
Also, these “Ad-driven” platforms only reward top creators. Most creators are left out - no matter how engaged their audience is. They have to constantly beat algorithms to reach out to their own audience.
Over 50 million people around the world consider themselves creators. 97% of them aren’t getting paid.
As a result, creators are flocking to platforms like Slack, Discord, Whatsapp & Telegram - none of which were built either for community engagement or creator monetization. Community creators have to go through the pain of managing multiple third-party tools to engage and monetize their community.
LikeMinds helps creators to convert their audience into a branded private community. They can monetize it by selling digital products like memberships, group chats, events, consultations, and courses.
As a platform purpose-built for community entrepreneurs, LikeMinds has inbuilt tools for member acquisition, onboarding, retention, moderation, monetization, and referrals. Our platform enables creators to drive high engagement and belonging via chat rooms, events, polls, member directory, and rewards.
These features are in addition to powerful business tools like community website, subscription management, event reminders, analytics dashboard, cohort creation, in-app banners, data export, and much more.
Custom integrations are also available for creators with existing assets.
In the last few months, we have helped 100+ creators monetize their communities. These include entertainers, fitness & wellness trainers, professional domain experts, language instructors, life coaches, financial experts, micro-entrepreneurship coaches, and exam prep coaches.
We are a team of entrepreneurs, techies, and community builders with credible backgrounds supported by 2 large VCs.
Requirements:
● Programming Languages: Java, AWS, Python, Ruby
