DeepSigns is revolutionizing document processing in the construction industry through advanced AI. We're currently in stealth working with a design partner in solving a critical industry pain point: the time-consuming, error-prone process of extracting meaningful data from contracts, bonds, and financial statements. Our AI-powered platform offers: - Intelligent document processing: Converting complex construction documents into structured, actionable data - Automated data extraction: Transforming unstructured documents into organized, searchable information - Smart document analysis: Quickly processing and standardizing varied document types across construction workflows Initial results: - 95% reduction in document processing time - Potential for millions in cost savings for construction firms - An estimated 1.5 million labor hours saved if our technology was applied across our design partner's industry We're creating a new standard for document processing in construction, moving outside of our current design partner's niche sector to the entire construction ecosystem. Our market is massive and underserved. The U.S. construction industry alone is worth over $1.3 trillion, with billions spent annually on document processing and management. We're well positioned to go after this market. DeepSigns isn't just another AI-wrapper startup. We're tackling real-world problems with solutions that can reshape an entire industry, and our solutions only get better with better frontier models. No worries of being 'steamrolled' here as the models improve. Our goal: become the obvious choice for construction document processing, saving clients time, money, and headaches. Join us in bringing clarity to construction's complex documentation.

The Trade is building the operating system for the people who design and build homes. We are developing an all-in-one software platform for contractors, interior designers, architects, builders, and other trade professionals who currently run their businesses across disconnected tools, spreadsheets, emails, accounting systems, project management apps, and invoicing platforms. Our goal is to bring the core workflows of a project-based trade business into one place, including project planning, client management, time tracking, billing, expenses, accounting, inventory, proposals, purchase orders, invoices, reporting, and AI-powered workflows. The Trade is being built alongside Marea Clark Interiors, a luxury residential interior design studio, giving us a real-world environment to test workflows, identify operational pain points, and build software around the actual needs of trade businesses. We are early, ambitious, and focused on solving real problems for an industry that has been underserved by modern software. Our vision is to help trade professionals operate more efficiently, make better decisions, deliver better client experiences, and spend less time buried in administrative work.

HexGrid Cloud is building the infrastructure that makes powerful AI models accessible to everyone. We're creating a private AI cloud where developers, creators, and AI teams can deploy cutting-edge generative models, launch ready-to-use ComfyUI workflows, and access dedicated GPUs without the complexity of managing infrastructure. Whether you're generating cinematic AI videos, building image-generation pipelines, fine-tuning models, or deploying production AI applications, HexGrid gives you the compute, tools, and flexibility to move from experimentation to production. Our platform brings together three core capabilities: - ComfyUI Cloud: Launch preconfigured image and video generation workflows with models like MiniMax H3, Wan, LTX, and FLUX. Bring your own models, custom nodes, and LoRAs. - On-Demand GPU Cloud: Access dedicated NVIDIA GPUs, including H100, H200, A100, and B200, with transparent pricing and full control over your environment. - AI Model APIs: Integrate powerful AI models into applications without managing the underlying infrastructure. We believe the future of AI should be open, flexible, and accessible. Developers shouldn't need to become infrastructure experts to build with the latest models, and creators shouldn't be limited by restrictive tools or shared computing environments. Our mission is simple: Make powerful AI infrastructure as easy to use as the applications built on top of it. We're building for a future where anyone can create, experiment, and scale with AI—on their own terms.
