Temasek joins $275m series C for US AI chip startup D-Matrix

D-Matrix, a US-based AI chip startup, has raised US$275 million in a series C round, bringing its valuation to US$2 billion.

The company, founded in 2019 and headquartered in Santa Clara, develops hardware and software for AI inference in data centers.

Investors in the round include Bullhound Capital, Triatomic Capital, Temasek, Qatar Investment Authority, EDBI, M12, Nautilus Venture Partners, Industry Ventures, and Mirae Asset.

D-Matrix said the new capital will support its product development and global expansion.

🧠 Food for thought

Implications, context, and why it matters.

Performance claims still lack third-party checks against NVIDIA’s lead

  • d-Matrix carries a $2 billion valuation tied to AI inference efficiency claims, yet no outside lab has verified them. NVIDIA H100 GPUs reach about 2000 TFLOPS with 8-bit floating point (FP8) precision 1.
  • Benchmarks from MosaicML (an AI model training platform) with CoreWeave (a GPU cloud provider) put H100 about 3x faster and roughly 30% cheaper than A100 for large-model training 1. d-Matrix needs third-party numbers for throughput, latency, and total cost of ownership (TCO) before buyers risk switching to alternative accelerators (specialized AI chips).
  • Without independent, real-world tests or deployment data, investors and customers cannot tell if the platform works at production scale.

Cloud providers and MLOps platforms can benefit if the SDK is ready

  • If d-Matrix hardware nears production, cloud infrastructure firms like CoreWeave that already offer NVIDIA H100 clusters for High-Performance Computing (HPC) and large ML jobs could add managed inference on lower-cost alternative accelerators (non-NVIDIA AI chips such as d-Matrix hardware) 1.
  • MLOps (machine learning operations) platforms with systems integrators (IT services firms that assemble, then optimize complex tech stacks) can offer model porting and optimization, but progress hinges on d-Matrix’s SDK (software development kit) supporting popular frameworks while matching NVIDIA’s Transformer Engine software library that enables FP8 training with minimal code changes 1.
  • Early movers across cloud, MLOps platforms, and systems integrators that build multi-accelerator skills could win enterprise business by lowering inference costs as models grow if d-Matrix can prove clear TCO gains over NVIDIA-based stacks.
