Tanka, a US-headquartered AI startup, has launched EverMemOS, a groundbreaking memory operating system that delivers virtually unlimited, persistent, and searchable memory to organizations, overcoming key barriers in enterprise AI. Inspired by neuroscience, this unified platform integrates scattered data from tools like Slack, Gmail, Notion, and WhatsApp into a single, evolvable source of truth, enabling teams to compound intelligence and drive context-aware collaboration.
EverMemOS tackles the enterprise challenge of information loss from fragmented documents and communications, where decisions bury and knowledge vanishes with departures. As Bessemer Venture Partners highlighted in their 2025 State of AI report, "Memory and Context are the new moats" for AI applications, yet most tools fall short. Tanka reimagines collaboration by converting interactions into retrievable memory, proactively surfacing insights and ensuring sustained growth. This neuroscience-inspired system employs a Dynamic & Static Memory Architecture for balanced recall, while Behavior-Driven AI learns from actions to suggest replies, track follow-ups, and orchestrate workflows.
EverMemOS sets a new benchmark with a 92.3% Locomo score—the highest reported on this evaluation for long-term conversational memory, encompassing question-answering, event summarization, and multimodal dialogue generation. Powered by atomic memory structuring, purification for clean reasoning, chain-of-thought generation, and advanced embedding-reranking recall, it excels in semantic memory and intelligent agents. "EverMemOS is the answer to the most fundamental question every startup faces: how do you preserve and leverage everything you learn as you build?" said Kisson Lin, CEO of Tanka. "For the first time, founders have an AI cofounder with true long-term memory, one that remembers every detail, learns continuously, and proactively drives execution. This is not just enhanced productivity—it's a new era of memory-powered competitive advantage."
Tanka's architecture delivers value through three core pillars:
These features address fast-paced startup needs, ensuring lessons and breakthroughs are retained and actionable.
Tanka's EverMemOS launch, timed for September 29, 2025, marks a pivotal advancement in AI-native tools, with plans to open-source the platform soon to foster developer-built innovations. By empowering persistent memory, Tanka equips organizations to thrive in dynamic environments, transforming data overload into a strategic asset for innovation and execution.
Tanka is a US-headquartered AI startup dedicated to pioneering long-term memory research and applications for founders and fast-moving teams. Inspired by cognitive neuroscience and built for the unique challenges of modern work, Tanka's mission is to empower every organization with a living, transferable memory—powered by the open EverMemOS platform.
