TYLsemi provides a reusable, standards-based chiplet portfolio—TYL.IO (connectivity), TYL.Power (in-package power delivery), and a planned TYL.Mem family—plus a full-stack TYL.Forge service for custom XPU and fabric designs. The company emphasizes UCIe-based die-to-die connectivity and integration with foundry and packaging partners to accelerate multi-die AI system development. TYLsemi emerged from stealth and raised $43 million in early-stage funding to accelerate product development and commercial engagement. It is partnering with TSMC to deliver IO and power chiplet samples to qualified customers in 2027 and is already engaging lead customers and tier-1 customer engagements that the company says validate its readiness. The firm is expanding its teams across silicon design, packaging, and systems engineering to support market deployment.
