Value proposition
A user-centric third-party memory layer that exists independently of foundation models, enabling AI to achieve personalized, continuous understanding of users across different models, sessions, and modalities — the critical missing layer between base model capability and truly useful AI applications.
Products and solutions
MemAura (native multimodal memory foundation module, launched June 2026), OmniMemory (memory framework with ADK/API), STKG (Spatio-Temporal Knowledge Graph), MEMLENS benchmark (co-released with NVIDIA, HKUST, CUHK)
Unique value
Native multimodal memory architecture (not text-only) with bionic hippocampus-inspired design; Spatio-Temporal Knowledge Graph (STKG) that anchors memory in time and space; 40-49% token cost reduction with sub-400ms retrieval latency; the only company in China exclusively focused on multimodal long-term memory.
Target customer
AI hardware manufacturers (companion robots, AI toys); vertical Agent scenarios (AI customer service, digital employees); embodied AI/robotics companies; legal and financial sector Agent applications
Industries served
AI companion hardware, AI customer service, digital employees, embodied AI/robotics, legal tech, fintech
Technology advantage
First-mover in multimodal long-term memory in China; bionic memory architecture mimicking human hippocampus; STKG with time-space anchoring for accurate recall; cold-hot storage tiering for cost efficiency; MEMLENS benchmark (global first multimodal long memory benchmark); SOTA on LoCoMo and LongMemEval benchmarks; latent space memory (E2P) for proactive intelligence
How they differentiate
Native multimodal architecture (not text-only RAG); time-anchored Spatio-Temporal Knowledge Graph vs. pure vector search; bionic hippocampus-inspired design; independent third-party memory layer not tied to any single foundation model; focus on proactive/active intelligence rather than passive response; sub-400ms latency with 40-49% token reduction
Main competitors
Mem0 (open-source AI memory), Letta (formerly MemGPT), Zep (context engineering and agent memory platform)
Key partnerships
NVIDIA (co-released MEMLENS benchmark), Hong Kong University of Science and Technology (HKUST), Chinese University of Hong Kong (CUHK)
Notable customers
Companion hardware manufacturers (including IP-licensed products like Beijing Zoo panda Menglan), AI solution providers for companion products, software companion products
Major milestones
Founded November 2025, STKG achieved SOTA on LoCoMo and LongMemEval benchmarks (December 2025), Launched MemAura memory foundation module (June 2026), Co-released MEMLENS benchmark with NVIDIA, HKUST, CUHK (May 2026) — global first multimodal long memory benchmark, Hugging Face Daily Paper top 3, Completed seed round of tens of millions RMB (July 2026)
Growth metrics
MemAura: 40-49% input token reduction; <400ms memory retrieval latency; <1s end-to-end first response; >80% comprehensive accuracy; STKG achieved 82.5% accuracy on LoCoMo benchmark with P95 retrieval latency under 2 seconds
Market positioning
First-mover and only dedicated multimodal long-term memory company in China; positioning as the independent memory infrastructure layer (analogous to Supabase for memory); competing in a nascent trillion-yuan (RMB) market with few players; highest competitor valuation in space under ¥20B
Geographic focus
China (domestic market) with global benchmark contributions
