Bizmark
Bizmark is a Y Combinator (S26) startup building an operating system for companies that make, move, or sell physical goods. It connects to the systems, inboxes, spreadsheets, documents, and know-how already inside a business and turns that context into automated quoting, dynamic scheduling, and inventory forecasting - shipping a working product in weeks rather than years.
Result (YC P26)
Result (YC P26) is an operating system for internet entrepreneurs. In one place a founder can incorporate, open accounts, take payments, build and launch a product, and run the day-to-day work of the business - marketing, support, content, and growth - with AI agents doing the work alongside them. The company is built for the 1-to-3-person teams of the post-work economy and was founded by teenage repeat builders Aaryan Kushwah and Savio Martin.
Surtr Defense Systems
Surtr Defense Systems builds ParallaxOS, a hardware-agnostic operating system for drone defense. It ingests data from any radar, RF detector, camera, or acoustic array, fuses it into a single common operating picture, applies AI threat classification, and passes human-authorized engagement recommendations to any effector. Founded in 2026 by two former Shield AI and Anduril autonomy engineers, the company is a Y Combinator Spring 2026 (P26) startup that raised roughly $4.8M in seed funding and field-tested its system with Ukraine's Brave1 defense cluster.
AICrete Corp.
AICrete Corp. is a Richmond, California company building AICreteOS, the first AI-powered operating system for the concrete and aggregates industry. Founded by UC Berkeley PhD Parham Aghdasi, it unifies quality control and operations - connecting batch, dispatch and truck data into one platform - to cut concrete costs by over $3 per cubic yard and reduce CO2 by an average of 42 lbs per cubic yard. The company raised over $9 million in seed funding led by Clear Ventures.
Mentra
Mentra is a San Francisco startup building MentraOS, an open-source operating system and app store for smart glasses, alongside Mentra Live, a 43-gram AI camera-glasses device. Founded in 2024 by MIT-dropout Cayden Pierce and Alex Israelov after they collaborated on the OpenSourceSmartGlasses project, Mentra wants to be the Android of smart glasses - a neutral software layer that lets developers ship apps and lets people actually use the hardware in the real world.
