Sett is a UA creative performance platform for mobile gaming. We build agentic AI systems that analyze performance data, generate diverse playable and video ad concepts, deploy them to networks, and learn from the results. The full creative loop. Automated, and done better than humans only. 97% of ad creatives fail. The math is brutal, and every UA team knows it. The only way to consistently find winners is to explore more, faster, and smarter than anyone else. Our system doesnt remix templates. It creates fundamentally different creative hypotheses, each one built from real performance signals. Studios go from guessing what works to knowing what to explore next. A system that creates fast, explores wide, and compounds what it learns. Creative fatigue is the bottleneck killing UA performance. ROAS decays, production cant keep up, and the next winning ad could change the trajectory of an entire title. Sett exists to fight that loop. Founded by people with a love for games and deep tech and AI expertise, pushing the limits of what AI technology can bring to mobile game studios.

The legal system is one of societys most important safeguards. Were making sure it keeps pace with the scale and complexity of the modern world it governs. Signals of legal risk and exposure are everywhere - dispersed across regulatory filings, corporate disclosures, and vast streams of digital information. They exist long before exposure compounds. Long before harm reaches scale. Long before anyone knew to look. Darrow is an AI research lab for the legal ecosystem. We study how legal exposure emerges across the modern economy and transform fragmented signals into structured legal intelligence - powering the tools used by law firms, insurers, and compliance teams to detect emerging risk and act with clarity and speed.

As the usage of commercial drones continues to proliferate, security officers to sensitive sites are facing escalating threats. To safeguard their sky perimeters against unauthorized drones, they are seeking an effective response that is tailored to their specific needs without compromising any existing security frameworks. Ensuring the safety and protection of communities – including people, assets and critical infrastructures- necessitates a comprehensive approach that goes beyond simply implementing more technology. This multifaceted challenge can only be addressed through tight collaboration among the key stakeholders in the drone ecosystem, including regulatory bodies, unmanned traffic management players, technology vendors and drone users. Recognizing the critical nature and complexity of this challenge, the Sentrycs team of Communications and Radio Frequency experts embarked on a mission in 2017 to develop modular solutions that can be fully customized to precisely meet the unique security requirements and drone ecosystems of each customer and partner. By uniting its field-proven technology and expertise in global drone environments, Sentrycs is leading the way towards a safer and more secure drone-driven future.
