Our work spans QR code utilities, family care coordination, local-first knowledge tools, cottage baker resources, and consumer products designed around clarity, trust, and everyday usefulness.
Below are selected brands and projects in the Terahertz portfolio.
Qrblox
Qrblox is a mobile app for scanning, saving, organizing, and sharing QR codes. It is designed for people who need a smarter way to scan QR codes from photos, screenshots, galleries, printed materials, and everyday places where camera scanning is awkward or inconvenient. You can learn more about the product on the Qrblox About page or read QR code guides, product updates, and scanning tips on the Qrblox Blog.
Qrblox helps users keep useful scan history, preview links before opening them, create and manage QR codes, and share profiles or links in new ways, including audio-based sharing. The product is built around practical QR code use cases for consumers, creators, businesses, and anyone who wants a cleaner way to collect and manage links.
JoinSandwich
JoinSandwich is an AI-native care coordination platform for families, caregivers, and home-care organizations. It is designed to help families stay aligned when supporting aging parents or loved ones, reducing the confusion that often comes from scattered texts, emails, documents, updates, and care notes. You can read more about the mission on the Sandwich Our Story page and explore updates, guides, and care-planning resources on the Sandwich Blog.
Sandwich brings together family-facing tools, care updates, shared workspaces, and agency-facing infrastructure so that important information can move through a clearer, more trusted system. The goal is to make care coordination easier to understand, easier to share, and easier to act on. For technical and agent-facing use cases, Sandwich also provides documentation and agent access resources.
LovedOne
LovedOne is a family inbox experience connected to the broader Sandwich platform. It gives relatives a shared place to receive important messages, coordinate care-related communication, and keep everyone on the same page without relying on separate inboxes or long text threads. You can learn more on the LovedOne About page or read family-care updates and product notes on the LovedOne Blog.
LovedOne is built for the everyday reality of family caregiving, where siblings, relatives, vendors, providers, and helpers may all be involved. By creating a calmer shared communication layer, LovedOne helps families reduce missed updates and make care coordination feel less fragmented.
Crosodo
Crosodo is a brand for cottage bakers, sourdough enthusiasts, and home-based food businesses. It combines apparel and gifts for bakers with practical resources for people navigating cottage food laws, local rules, and the business side of selling baked goods from home. You can learn more on the Crosodo About page, read baking and cottage-food notes on the Crosodo Blog, or explore the Cottage Baker's Field Guide.
Crosodo is built for the home baker community, from people who love sourdough, lamination, and baking culture to cottage food entrepreneurs trying to understand how to operate more confidently. The brand brings together products, educational resources, and directory-style tools to support bakers as both makers and small business owners.
Frosh
Frosh is a local-first and hosted MediaWiki platform for creating, editing, and maintaining private wiki sites. It is designed to make it easier to run a personal or team wiki without dealing with low-level server setup from scratch. You can learn more on the Frosh About page, read product updates and knowledge-management guides on the Frosh Blog, or explore the Frosh Documentation.
Frosh supports private-by-default MediaWiki workflows, desktop and hosted wiki management, AI-assisted text-to-wiki conversion, backups, restore workflows, custom domains, and CLI or MCP integrations for agents and automation. It is especially useful for people who want a private knowledge base, an agent-friendly wiki workflow, or a local documentation system that can grow into more automated publishing and collaboration workflows over time.
