- Geost
Robotics, Semiconductors
Geost operates within the national security space, specializing in the design and production of advanced electro-optical and infrared (EO/IR) sensor payloads for space and ground-based applications. His background in optical sciences has been central to the company's focus on developing sophisticated sensor systems. The firm primarily serves U.S. defense and intelligence agencies, including the Department of Defense, the Air Force, and the Space Force. Geost's business model revolves around providing hardware and mission support solutions for critical applications such as missile warning and tracking, space domain awareness (SDA), intelligence, surveillance, and reconnaissance (ISR), and laser communications. It often collaborates with major defense prime contractors like Northrop Grumman and L3Harris Technologies on significant government contracts. Revenue is generated through federal contracts for research, development, and production of these sensor systems. Geost's product portfolio includes compact and affordable EO/IR sensors designed for proliferated space architectures, which involve large networks of smaller, less expensive satellites. Key products include the Starlite resiliency payloads, Mercury missile-warning payloads, and Phoenix fire-control payloads. The company also develops ground-based systems, such as the Wolverine Optical Ground Terminals, which support satellite communications and tracking. A notable feature of its offerings is the integration of artificial intelligence and machine learning for autonomous data processing and threat response, minimizing the need for human intervention. A significant milestone occurred in 2021 when private equity firm ATL Partners acquired a majority stake, integrating Geost into the LightRidge Solutions platform alongside Trident Systems and Ophir Corp. This acquisition provided the capital for significant expansion, leading to a 600% increase in employee count over three years and the doubling of its production facility. In May 2025, it was announced that Rocket Lab USA, Inc. would acquire Geost from LightRidge Solutions, a move intended to enhance Rocket Lab's capabilities as an end-to-end provider of national security space solutions by bringing critical payload technology in-house.

Get UnLooped is an operational diagnostics practice that specializes in identifying and resolving profit leaks for job-based businesses. His experience began in a small plumbing company, where he focused on rebuilding billing systems and implementing job costing, which gave him his first insights into the gap between work completed and money collected. This hands-on experience on the shop floor, in the field, and as an owner informed the creation of Get UnLooped, a practice designed to provide targeted solutions for businesses that traditional accounting often overlooks. The firm primarily serves owner-operators of industrial and trade companies with 10 to 50 employees and annual revenues between $2 million and $20 million. This client base includes construction trades, machine shops, defense suppliers, specialty manufacturing, fabrication, and engineering firms—businesses where revenue is driven by jobs, projects, and billable hours. Get UnLooped addresses the common paradox where business owners see high activity and revenue but stagnant bank balances, a problem often caused by hidden inefficiencies in the quote-to-cash workflow. These inefficiencies, or 'profit leaks', can occur from inaccurate quoting, poor scope control, lost productivity, and undisciplined billing. The core of Get UnLooped's service is the 'Profit Leak Scan,' a complimentary 60-minute diagnostic of a client's quote-to-cash process. During this session, the firm maps out the workflow to pinpoint exactly where profit is disappearing. Following the scan, clients receive a 'Profit Leak Map' that details these findings. The next step is to 'UnLoop the system,' which involves implementing and hard-coding systematic fixes into daily operations. This ensures that profitability is built into the workflow, allowing owners to trust their financial numbers and regain control over their margins. The goal is to create systems that make profit predictable and operations independent of constant owner oversight, ultimately building a more valuable and exit-ready business.

- Gradebird
Education
Gradebird, operated by Avian Educational Software, Inc., provides an artificial intelligence-assisted workflow designed to streamline the grading of in-person, handwritten examinations. The platform is tailored for higher education, particularly within STEM disciplines where answers often involve complex calculations, diagrams, and multi-step reasoning. Gralla initiated the project in 2024 as a student self-assessment tool and repurposed it in early 2026 following advances in AI's ability to interpret handwritten content. The business model targets professors and educational institutions, offering a solution that bridges the gap between traditional paper exams and digital efficiency. The workflow begins with instructors authoring their exam and rubric within the Gradebird system, which then generates printable, uniquely QR-coded exam packets. After students complete the exams on paper, the documents are scanned in bulk. Gradebird's system automatically sorts the responses by student and question using the QR codes and employs AI to generate draft assessments, including scores and detailed feedback, aligned with the instructor's rubric. A core tenet of the service is maintaining instructor oversight; all AI-generated grades and feedback are presented as suggestions for the instructor to review, edit, and approve before releasing results to students. This approach allows the platform to handle nuanced, free-form work that legacy autograders cannot, while ensuring academic accountability. The service is designed to be FERPA-compliant, with a commitment to not selling student data or using it to train generalized AI models. Gradebird secured a licensing deal with the University of Arizona in June 2026 and began offering external pilots in the summer of the same year.
