Marginalia PartnersMarginalia PartnersAI, made practical
Platforms we've built

Proof isn't a pitch deck. It's shipped solutions.

Before Marginalia advises a single firm, the work already exists. These are real AI and automation platforms our founder has designed and shipped — each one demonstrating, in production, the kind of practical AI we bring to independent firms.

Real platforms, real results.

Built and shipped by our founder — proof of capability, not staged demos. As we complete client engagements, named firm case studies (reviewed and approved before publication) join them here.

Duho ↗ AI chief-of-staff
An AI chief-of-staff that runs a whole portfolio
  • Delivered a private AI ops platform that runs a whole portfolio
  • Built work dispatch + status tracking across products
  • Automated cross-product coordination
  • Human steers priorities; AI runs the back office
The transferable lessonIf AI can run the back office of an entire portfolio, running the recurring operations of a single firm is well within reach.
Pocket PM ↗ product & roadmap AI
Turns a founder's raw notes into a structured plan
  • Delivered their flagship Concept Forge — an AI model that turns raw notes into structured product plans
  • Auto-generated roadmaps, specs & task breakdowns
  • Built the full PM engine — tracking + multi-agent dispatch
  • Shipped end-to-end, in production
The transferable lessonMost of what slows a firm down isn't the thinking — it's the structuring and write-up around it. That's exactly the repeatable layer AI removes, so your people spend their time deciding, not formatting.
YourCondoManager ↗ back-office automation
Runs the monthly admin a property board repeats
  • Delivered a live multi-tenant SaaS for condo & HOA boards
  • Automated assessments, ledger & payment receipts
  • Built templated, auto-sent owner communications
  • Made recurring monthly admin fully hands-off
The transferable lessonEvery expertise-led business has a recurring billing-and-comms tail that eats hours. Automating that tail — not the judgment above it — is usually the fastest, safest first AI win.
PlinthKeep ↗ workflow automation
Puts a landlord's tenants, repairs, and books in one place
  • Delivered a full rental-property platform — tenants, repairs & books in one place
  • Built automated application intake & triage
  • Auto-routed repair requests — no manual chasing
  • Shipped the operating ledger, built in
The transferable lessonIntake and triage — the work that happens before the real work — is repeatable and rules-based. It's where automation quietly recovers the most time in a small, expertise-driven firm.
Neostriatum ↗ knowledge aggregation
Turns scattered notes into one searchable memory
  • Delivered a second-brain that turns scattered notes into one searchable memory
  • Built AI auto-transcription, structuring & tagging
  • Unified cross-device capture into a single store
  • Turned fragments into an actionable knowledge base
The transferable lessonThe biggest blocker to a firm's first AI project is rarely the AI — it's data living in five disconnected places. Getting one reliable, structured source is the unglamorous step that makes everything after it work.
KeyboardIQ ↗ AI in everyday work
Brings AI help right into your everyday typing
  • Delivered a native macOS app — AI assistance inside everyday typing
  • Works system-wide, in any app
  • Built real-time AI at the keystroke
  • Shipped with zero new tool to adopt
The transferable lessonAI that lands inside existing tools gets adopted; AI that demands a brand-new system gets abandoned. We ship capabilities into the software your team already opens every morning.
VibeDispatcher ↗ voice-first AI control
Lets you run your AI by voice, from anywhere
  • Delivered a voice-first command channel for an AI work agent
  • Run real build & work tasks by talking — Mac or phone
  • Built conversation-as-interface, no dashboard
  • Shipped hands-free control from anywhere
The transferable lessonAdoption lives or dies on friction. Put the AI where people already are — their voice, their phone — and they actually use it.
