Our Brands
Terahertz develops practical digital products, consumer brands, and AI-powered tools that help people organize information, coordinate care, build knowledge systems, and solve everyday problems. Across our projects, we focus on products that are useful, approachable, and built for real-world workflows.
Our portfolio includes apps, directories, resources, and community-focused brands across QR technology, family care, cottage baking, and private knowledge management.
Qrblox
Qrblox helps people scan, save, organize, and reuse QR codes from the places they actually encounter them — including photos, screenshots, printed materials, signs, packaging, and shared links. Instead of treating QR scanning as a one-time action, Qrblox gives users a way to keep a cleaner record of the codes and links they want to remember. Learn more on the Qrblox About page or browse QR tips, product updates, and guides on the Qrblox Blog.
The app is built for consumers, creators, businesses, and teams that want more control over QR code history, link previews, sharing, and organization. Qrblox also explores new ways to connect physical and digital information, including profile sharing, QR creation, and more flexible ways to manage codes over time.
JoinSandwich
JoinSandwich is designed for families, caregivers, and care organizations that need a clearer way to coordinate support for aging parents and loved ones. Care often involves scattered texts, missed updates, appointments, notes, documents, and decisions; Sandwich brings those pieces into a more organized care layer. Read more about the mission on the Sandwich Our Story page or explore care-planning resources on the Sandwich Blog.
Sandwich supports both family-facing coordination and more advanced workflows for agencies, operators, and AI-assisted care systems. It is built to make important information easier to share, understand, and act on. For agent and technical use cases, Sandwich also offers documentation and agent access resources.
LovedOne
LovedOne is a shared family inbox for care-related communication. It gives relatives a common place to follow important updates, messages, and coordination details without relying only on scattered group texts or separate email threads. Visit the LovedOne About page or read family-care updates and product notes on the LovedOne Blog.
LovedOne is built for families where multiple people may be involved in supporting one person — siblings, spouses, adult children, caregivers, providers, helpers, and vendors. By giving everyone a more organized communication hub, LovedOne helps reduce confusion and makes family care easier to follow.
Crosodo
Crosodo is a cottage baking and sourdough-inspired brand for home bakers, microbakeries, and people who love bread culture. The brand includes gifts and apparel for bakers, along with resources for people learning about cottage food laws, home baking businesses, and the practical side of selling baked goods. Learn more on the Crosodo About page, read baking and cottage-food articles on the Crosodo Blog, or explore the Cottage Baker’s Field Guide.
Crosodo is made for sourdough bakers, cottage food entrepreneurs, and anyone building a small baking business from home. It combines community, educational resources, and baker-focused products to support people who are turning their love of bread into something more structured.
Frosh
Frosh helps people create and manage private wiki systems without needing to manually assemble a technical stack from the ground up. It is built around local-first and hosted MediaWiki workflows for people who want a reliable place to store notes, documentation, research, project knowledge, and structured information. Learn more on the Frosh About page, read updates and knowledge-management articles on the Frosh Blog, or explore the Frosh Documentation.
Frosh supports private knowledge bases, AI-assisted text-to-wiki workflows, backups, restore tools, custom domains, CLI integrations, and agent-friendly documentation systems. It is especially useful for people and teams who want a wiki that can start locally, stay private by default, and grow into a more automated knowledge workflow over time.
