Social networking app built to retain real users

Real-time feeds, messaging, communities, and creator tools. We've built social platforms from MVP to millions of users iOS, Android and web since 2008 for clients including Sony, Volkswagen and the British Council.

AI-powered platform

Smart AI that ranks
and retains users

Every social platform we build ships with AI capabilities that personalise feeds, moderate content, and grow your community automatically, from day one.

  • Feed ranking algorithm

    Real-time content ranking using engagement signals, recency, and social graph depth so no two users ever see the same feed.

  • AI content moderation

    Multimodal classifiers (text, image, video) flag violations, hate speech, and spam before they reach your community with a human appeal flow.

  • Smart notification engine

    AI-driven notification timing and priority scoring alerts land when users are most likely to re-engage, not just when events fire.

  • People you may know

    Graph-based connection recommendations using shared connections, mutual groups, interests, and historical interaction patterns.

  • Community health monitor

    Real-time sentiment tracking, toxicity scoring, and trend detection so you spot community issues and viral moments before they escalate.

  • Creator & engagement insights

    Automated dashboards showing creators their top content, best posting windows, follower growth drivers, and monetisation opportunities.

Community strategy to live, six phases

PHASE 01 / Social Audit

PHASE 02 / App Blueprint

Wireframes + interactive prototype

Core flows onboarding, feed, messaging, profiles, notifications wireframed, prototyped, and validated with real users before development begins.

PHASE 03 / Dev Sprint

Real-time backend + mobile apps

Activity feeds, user graph, messaging, push notifications, and media handling built in parallel across iOS, Android and web with bi-weekly demos and a staging environment live from week two.

PHASE 04 / AI Integration

Smart feed + content safety layer

Personalisation engine, content classifiers, recommendation models, and moderation queue integrated and trained on seed data before your first public users arrive.

PHASE 05 / Go-Live

Social-scale load testing + App Store submission

We stress-test your platform under simulated viral traffic spikes, resolve every performance bottleneck, and manage App Store and Play Store submission end-to-end so your launch day is smooth, not scrambled.
