Opt32

Opt32, which presents itself publicly under the name Spring Silicon, is a New York-based company developing compute infrastructure for machine autonomy. The company's stated position is that robots, drones, autonomous vehicles and heavy industry have been left behind by recent AI progress, since sectors such as manufacturing, defense, energy and transportation run on what it characterizes as outdated and inefficient compute systems while large models are deployed to the cloud [0][1].

The product scope described on the company site is a full-stack compute stack spanning compilers through ASICs, designed specifically for physical AI rather than adapted from scaled-down datacenter or consumer hardware. The company states an objective of becoming a vertically integrated compute stack for edge inference used in autonomous machines [0][1]. External descriptions align with this: Vine Ventures categorizes Opt32 under robotics, infrastructure and AI and summarizes it as "modern infrastructure for edge machine learning" [4], while a write-up of the 2026 Thiel Fellowship class describes Opt32 as building compute infrastructure to put AI onboard physical objects including robots, cars and drones, and characterizes its focus as edge AI compilers for inference on physical hardware [5].

Founding story

Opt32 is associated with founder Milan Lustig, who is listed as the company's founder by investor Vine Ventures [4]. Coverage of the 2026 Thiel Fellowship states Lustig is on leave from Harvard, where he studied CS and Philosophy, and describes prior research including ML accelerator architecture work at Stony Brook University's COMPAS Lab, parsing work at the University of Michigan's Future of Programming Lab, and an end-to-end ML compiler he built targeting a hardware-agnostic ISA (MLISA) at Stony Brook [5]. The company site states its founding team comes from Harvard, Yale, Carnegie Mellon, Johns Hopkins and Palantir, with research backgrounds in compilers, chip design, machine learning and robotics [0][1].

Traction

Publicly available signals are limited to investor backing and recognition rather than disclosed commercial metrics. The company lists Vine Ventures, BoxGroup, Soma, SV Angel and Valkyrie as investors [0][1], appears in Vine Ventures' portfolio [4], and its founder was named a 2026 Thiel Fellow, a program awarding $250,000 per fellow over two years [5]. The company is recruiting founding engineers across software and hardware roles [0][1].

Latest developments

An April 2026 profile of the 2026 Thiel Fellowship cohort names Opt32 founder Milan Lustig as a fellow, placing the company in the cohort's physical AI and robotics group [5]. The company website concurrently advertises open founding engineer positions in embedded systems, OS, compilers and kernels, as well as PCB, FPGA and ASIC design [0][1].
