As answered by people managing HackerRank and Walls.io.
Walls.io's answer:
Walls.io is a flexible, enterprise-ready social wall platform that helps brands collect, moderate, and display social media content and direct user submissions in real time—across websites, events, apps, intranets, and digital signage.
What truly sets Walls.io apart is its combination of ease of use, deep moderation control, and privacy-first design. With features like Direct Posts (no social account required), GDPR-friendly moderation workflows, and broad integrations (event platforms, CMSs, digital signage tools), Walls.io works just as well for public campaigns as it does for internal communications and regulated industries.
Walls.io's answer:
People choose Walls.io when they need reliable engagement without risk. Compared to competitors, Walls.io offers:
Direct Posts with QR codes, enabling safe participation without forcing users onto social networks
Advanced moderation and approval flows, ideal for large screens, internal comms, and conservative industries
True omnichannel flexibility: one wall can live on a website, at a live event, inside an app, and on office screens
Strong compliance posture, supporting GDPR-conscious brands and global organizations
In short, Walls.io isn’t just about displaying social media, it’s about owning and controlling the experience while still feeling live and authentic.
Walls.io's answer:
Walls.io’s primary audience includes:
Marketing and event teams running live, hybrid, or virtual events
Internal communications and HR teams focused on employee engagement and employer branding
Enterprise and public-sector organizations that require moderation, privacy, and brand safety
Sports, education, and cultural institutions engaging large, diverse audiences on-site and online
They typically share one challenge: wanting high participation and visibility without losing control or compliance.
Walls.io's answer:
Walls.io was founded in Austria with the goal of making social media content usable beyond native platforms, especially at events and on owned channels.
Early on, the team recognized a gap: brands wanted the energy of social media, but not the chaos, data risks, or platform dependency. Walls.io evolved into a robust platform that balances real-time engagement with moderation, flexibility, and ownership. It has since grown into a global solution used by enterprises, NGOs, universities, and major brands worldwide.
Walls.io's answer:
At a high level, Walls.io is built on a modern SaaS architecture that includes:
Cloud-based infrastructure for scalability and global performance
API-driven integrations with major social networks, CMSs, event platforms, and signage tools
Real-time content ingestion and rendering technologies
Secure moderation, storage, and consent mechanisms aligned with data protection standards
Walls.io's answer:
Walls.io is trusted by well-known global organizations across industries, including:
World Health Organization (WHO) – for large-scale international events
Cisco – for global employee engagement and event campaigns
Sandvik – connecting employees across 150+ countries
Leonardo (aerospace & defense) – for safe, approved social sharing
Oklahoma City Thunder (NBA) – powering fan engagement at live games
Universities, trade shows, and global enterprises such as NAMM, BearingPoint, and Champlain College
These customers rely on Walls.io for its stability, moderation, and ability to scale engagement safely.
