Security at most companies is reactive. A checkbox for auditors. A speed bump for engineers. A department that says no. That's not what we're building. The Company Sendbird is the #1 CPaaS platform for in-app communications — an enterprise-grade infrastructure company that gives businesses the APIs and SDKs to embed real-time chat, voice, and video directly into their own products. Over 4,000 brands trust us. Seven billion messages flow through our platform every month. 300 million monthly active users. We powered conversations for DoorDash, Match Group, Noom, Yahoo Sports, Rakuten, and thousands more. We were good at what we did. Really good. So we asked what comes next. With decades of leadership in communications infrastructure, the answer was clear: AI. In February 2025, we launched our AI agent for enterprise CX. Later that year, we introduced Delight.ai — and the name says everything about what we believe. AI's real promise isn't efficiency. It isn't cost savings. It's restoring what customer experience lost somewhere along the way: the feeling of being understood, of being genuinely cared for. We don't want customers to feel satisfied. We want them to feel delighted. The Product Delight.ai is the AI concierge for customer experience. Most AI agents forget you the moment the conversation ends. Ours doesn't. Delight.ai builds memory over time, learns preferences, and connects context across every channel—chat, SMS, email, voice, WhatsApp—without losing the thread. We're building AI that makes customers feel understood, seen, and remembered. Why Head of IT & Security We're an AI company handling enterprise-grade conversations at global scale, and our customers trust us with data that matters. That trust isn't a nice-to-have. It's a competitive differentiator. It's why DoorDash and Match Group chose us. It's why we've earned certifications that our competitors are still chasing. Security here means being a partner to the business, not a blocker. It mea
