ContextSDK is designed to enhance mobile app engagement and revenue by leveraging real-world user context with machine learning. ContextSDK collects more than 200 signals from the modern smartphone to assess a user’s real-world context instantly - whether theyre commuting, walking or relaxing - and use this for intent detection. This allows for the delivery of precisely timed, context-aware notifications and content that enhance user satisfaction and drive conversions. Its on-device processing ensures privacy by avoiding cloud transfers, which preserves user trust. ContextSDK’s vision is to establish real-world context data as the new gold standard in mobile app engagement, providing product owners and CMOs with a powerful tool to continuously optimize user experiences.

Flank is a secure, agentic platform built for enterprise legal work. It lets you deploy specialised agents that work like paralegals to handle repeat requests from the rest of the business. Agents have a diverse range of skills, just like a paralegal. They can handle tasks like: - Intake and routing - Contract review - Document drafting - Objection handling - Answering questions - Research of company knowledge Agents work by themselves, but never without oversight. You set permissions and guardrails, and choose how and when a lawyer gets involved. Flank agents handle the volume, so in-house lawyers can focus on judgement.
