Principle

Trust as architecture, not policy.

Most software asks you to trust its operator. A privacy policy is a promise; a promise can be broken, subpoenaed, or acquired. Every product in this portfolio takes the other route: the guarantee is built into how the system works, so the operator can't break it. Not won't. Can't.

  • Proper FeedbackCaller numbers are one-way hashed and original recordings discarded. There is nothing to leak.
  • Better LetterReaders pay writers directly. The platform never touches the money.
  • Secretly SovereignData residency is enforced by routing and zone-scoped keys, not by a compliance document.
  • ARCProofs anchor to the Bitcoin blockchain and verify offline. Cadence hash-chains time records at write. Evidence, not assertions.
  • PSA.XYZNo accounts, no stored phone numbers. Anonymity is the substrate, not a setting.
  • Claudacio.usWhat surfaces is chosen by curators you follow: human judgment, not an engagement engine.

Portfolio

Built and wired. Launching in sequence.

Organizational feedback

Proper Feedback

A phone number your people can call. Voices masked, numbers hashed, honesty made sayable. For schools, teams, and cities.

properfeedback.com Publishing

Better Letter

A newsletter platform you own outright: your CMS, your list, your payment rail. Flat fee. No revenue share, ever.

betterletter.io Data sovereignty

Secretly Sovereign

File sync and share where residency, processing locality, and key ownership are architectural properties, not policy documents.

domain tba Evidentiary infrastructure

ARC

Two products, one anchor. Proof timestamps records on Bitcoin; Cadence makes time tracking itself audit-grade evidence.

arcproof.ing Public voice

PSA.XYZ

A free anonymous public voicemail archive. Call, speak, publish. No login, no algorithm. A wall, not a feed.

psa.xyz Social bookmarking

Claudacio.us

del.icio.us reborn: save in one move, agents tag and summarize, curators you follow surface what's worth reading.

Services

Not everything we build is a product.

Some of it is a service: editorial sites and campaigns, designed, written, and built end to end. Two that are live now:

[ Fig. 1 ]knowware.press · the companion site for a book built from eighty-one syntheses: dossiers, a periodic table of voices, a citation graph
Screenshot: h1a.ca, the H1, eh? recruitment campaign
[ Fig. 2 ]h1a.ca · a recruitment campaign with no application form: thirteen seats in Calgary, and the way in is breaking one of the problems

About

Small, sharp, independent.

We're based in Calgary, Alberta. We build products end to end (design, infrastructure, and the words on the page) and we ship them when they're finished, not when a funding cycle demands it.
