Sinch
The Swedish company you have never heard of sends the one-time passcodes, delivery alerts and marketing texts that reach your phone billions of times a day. This is how Sinch turned invisible infrastructure into a global business.
Visibl Semiconductors
Visibl Semiconductors (YC W26) is a San Francisco startup building an AI-native coordination layer for chip design. Its software watches specifications, RTL code, CI pipelines and EDA tool outputs for 'drift' - the slow divergence between what a chip was supposed to do and what the design actually does - then opens evidence-backed cases and proposes review-ready fixes that a human must approve before anything ships. Founded by Bryce Neil (CEO) and Jordon Kashanchi (CTO), the company targets verification and methodology owners on teams heading toward integration, design freeze and tapeout, where a single missed misalignment can trigger a $5M-$20M respin.
Synopsys, Inc.
Synopsys is an American electronic design automation (EDA) company that builds the software, IP, and simulation tools chipmakers use to design, verify, and manufacture advanced semiconductors. Founded in 1986 around logic-synthesis technology, it is one of three companies that dominate the EDA market and, following its $35 billion acquisition of Ansys in July 2025, has expanded from chip design automation into full silicon-to-systems engineering across electronics, structures, fluids, and optics.
Cadence Design Systems
Cadence Design Systems is a San Jose-based computational software company that builds the electronic design automation (EDA) tools, hardware systems, and semiconductor IP used to design chips, printed circuit boards, and full electromechanical systems. Under its Intelligent System Design strategy, Cadence software sits behind a large share of the world's advanced silicon - powering everything from smartphones and data-center accelerators to cars, aircraft, and, increasingly, AI-driven design automation and drug discovery.
Synopsys Inc
Synopsys is the quiet giant behind the world's chips. Its electronic design automation (EDA) software, semiconductor IP, and AI-driven design tools are used to design and verify nearly every advanced silicon chip on the planet - from smartphone processors to AI accelerators. Founded in 1986 by Aart de Geus and led today by CEO Sassine Ghazi, the Sunnyvale company turned the impossibly hard task of laying out billions of transistors into a software problem, and now layers AI on top of it. Its 2025 acquisition of simulation leader Ansys pushed it deeper into multiphysics and systems engineering.
