GoKawiilA new semiconductor firm, TYLsemi (pronounced Tile Semi), publicly revealed itself this month, alongside $43 million in early-stage funding and an ambitious plan to simplify the development of custom processors for AI infrastructure.
Dozens of contract chip designers can develop custom processors of different complexity. However, only a few companies can offer custom silicon design services using standard chiplets to speed up and derisk the development cycle. TYLsemi is aiming to join their ranks. We spoke to their founders to find out how the nascent business might pull it off.
Emerging from stealth
Rather than compete solely as another custom ASIC design house, TYLsemi intends to offer reusable, standards-based connectivity, power delivery, and eventually memory chiplets that customers can combine with their own differentiating compute silicon to build a unique system-in-package. For companies that do not intend to conduct semiconductor development themselves, TYLsemi will also provide an end-to-end service that includes design and implementation of a differentiating chiplet, packaging, qualification, and high-volume production, essentially enabling companies without any silicon development skills to offer their own multi-chiplet processors.

TYLsemi was co-founded by Mohit Gupta and Sunil Bhardwaj, semiconductor veterans who have led global engineering, operations, and business teams at Alphawave, SiFive, Cadence, Rambus, and other chip companies, and who collectively have plenty of experience with both standard and custom silicon. Mohit Gupta, a co-founder and chief executive of TYLsemi, believes that the time to establish a company that specializes in pre-approved chiplets and custom ASIC design is right now.
"Chiplets have been discussed for seven or eight years, but several things have changed in the last three or four years," Gupta told Tom's Hardware Premium. "First, advanced packaging has matured significantly. There are now multiple 2.5D and 3D integration options in volume production. Customers are not limited to one packaging technology or supplier; there are options from foundries and OSATs, including TSMC, Intel, ASE, and Amkor. Second, die-to-die standards have arrived. In the past, most chiplet implementations relied on proprietary interfaces. UCIe is now moving into production deployments, including at hyperscalers, which makes heterogeneous integration much more practical. Third, supply-chain resilience has become critical. Customers increasingly want modular and potentially multi-source strategies rather than a single point of failure. Those factors have created an environment that did not exist four or five years ago."
AI accelerators will be among the primary applications to benefit from multi-chiplet design, as we have already learned from AMD and Nvidia.
"The AI accelerator market is on track to reach $604 billion by 2033, and custom silicon XPUs built for specific hyperscaler workloads are the fastest-growing segment," Gupta said. "At that scale, chiplet-based design is no longer optional, yet there is no pure-play chiplet company serving this market with a full portfolio. TYLsemi closes that gap with standards-based chiplets combined with UCIe-based die-to-die connectivity, XPU-aware design, packaging, and integration — giving customers a fast, proven path to AI-era silicon."
