About our tech: With over 50 patents, ANELLO uses Silicon Photonics to dramatically reduce the size, weight, and power (+cost) of the fiber-optic gyroscope (FOG) typically required in submarines and large aircraft for measuring the most precise system balance for navigation. We call this new version of a FOG, a SiPhOG. We're building self-contained navigation systems (IMU&INS) with our SiPhOGs at a fraction of the size, weight, cost, and power of FOGs. We're bringing the navigation precision in GPS-denied environments that submarines have to autonomous devices for any use case (air, land, sea). Our products are dual use for commercial and defense customers. We are a profitable Series-B start-up shipping product for just the past 2.5 years, just 40 ppl. Our company culture is very collaborative and allows for the ability to own and contribute on multiple NPI products, while leaning more into other areas of technical interest. We have multiple products heading into high-volume production, with additional products at earlier stages of the lifecycle (including concept mode). We're backed by powerhouse companies like In-Q-Tel, Lockheed, and MESH. There is great interest in our technology and in a short time have strong revenue and designed into into many autonomous platforms in dynamic segments like Autonomous Maritime and Aerial, Construction/Mining, AgTech, Robotics. We have a very collaborative culture that promotes learning and innovation + we believe there is significant financial equity upside here given our revenue trajectory.

At Rec (rec.us) , we’re reimagining how the world plays, trains, competes, explores and gets outside. Our mission is to empower the entire recreation community to thrive, and our vision is bold: power recreation worldwide. Booking a tennis court? Signing your kid up for swim lessons?

We're partnering with parks & rec departments, golf courses, campgrounds, gyms and more to transform a $105B industry stuck in the Stone Age. We’re not just putting recreation online—we’re redesigning it from the ground up, for the mobile-first, AI-powered world we live in. And about AI? From simplifying registration flows to auto-scheduling entire recreation departments to empowering parks & rec staff to utilize the data to make their programming better, we use AI where it makes a real impact. We’re builders at heart, using the best tools to solve real problems for real communities. If you get fired up by making tech that actually matters—to families, coaches, and kids all over the country—come join us.

Every business that sells something a person has to install, use, or repair already has the video, cannot search it, and has customers asking about it anyway. We built the thing that finds the answer. Businesses pay us to turn how-to video into an expert on their own channels that answers their customers in their own voice.

We’re building a collaborative cloud for teams to work in the physical world. Here’s the master plan: 1. Build a world-class Engineering, Production, and Sales organizations. 2. Create a product that Gives Operators Superpowers. 3.

Agentic Operating Procedures for your ERP. Execute at machine speed, learn from every exception, and improve with every transaction.

We are little confidential on what exactly we do. Here is the high level pich: Most "AI agents" are demos — they can't remember a customer, decide unsupervised, or act on real systems, so a human babysits every step and the ROI never arrives. We give digital coworkers persistent memory, a governed identity, and scoped authority to act, with provenance and audit enforced at runtime, not in a contract. We wedge into mid-market ecommerce CX (Shopify / Zendesk), where the ROI is immediate, then expand into every function a trusted coworker can own.
