Qrblox
A mobile app for scanning, saving, organizing, and sharing QR codes across photos, screenshots, galleries, printed materials, and everyday surfaces.
Qrblox 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.
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
An AI-native care coordination platform for families, caregivers, and home-care organizations.
JoinSandwich 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.
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.

LovedOne
A family inbox experience connected to the broader Sandwich platform for shared care communication.
LovedOne 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.
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.

Frosh
A local-first and hosted MediaWiki platform for private wiki sites and agent-friendly documentation workflows.
Frosh is designed to make it easier to run a personal or team wiki without dealing with low-level server setup from scratch.
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.
