Platforms we've built — Marginalia Partners

¶ These are real platforms, built and shipped by our founder — not faked client engagements. They're proof of capability: each one shows the automation pattern at work and the lesson that transfers to a firm like yours. As we complete client engagements, named firm case studies (reviewed and approved by each firm before publication) will appear alongside them.

Pocket PM · product & roadmap AI§

Pocket PM ↗

Turns a founder's raw notes into a structured plan

An AI project-management platform whose "Concept Forge" takes a founder's raw, unstructured notes and turns them into an organized product concept and roadmap. The judgment stays human; the structuring, drafting, and first-pass organization are automated.

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¶

YourCondoManager ↗

Runs the monthly admin a property board repeats

A live SaaS platform for condo and HOA management that automates the recurring admin a board faces every month — assessments and the ledger, payment receipts, and templated owner communications — so the people running a property spend less time on paperwork.

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†

PlinthKeep ↗

Puts a landlord's tenants, repairs, and books in one place

A rental-property management platform built for independent owner-operators — handling tenant applications, repair requests, and the operating ledger in one place, with the intake and routing work automated rather than chased by hand.

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‡

Neostriatum ↗

Turns scattered notes into one searchable memory

A second-brain platform that aggregates years of voice notes, written notes, and content scattered across devices into a single structured, searchable system — turning a pile of fragments into something a person can actually act on.

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§

KeyboardIQ ↗

Brings AI help right into your everyday typing

A native macOS product that brings AI assistance directly into everyday typing and workflow — meeting people inside the tools they already use, rather than asking them to adopt a separate new system.

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‡

VibeDispatcher ↗

Lets you run your AI by voice, from anywhere

A voice-first command channel for an AI coding/work agent — talk to it from your Mac or your phone and it carries out the task. The interface is a conversation, not a dashboard.

The transferable lessonAdoption lives or dies on friction. Put the AI where people already are — their voice, their phone — and they actually use it.

Duho · AI chief-of-staff◊

Duho · private platform

An AI chief-of-staff that runs a whole portfolio

A private AI operations platform that coordinates a multi-product portfolio end to end — dispatching work, tracking status, and handling cross-product coordination, with a human steering the priorities.

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.

Your firm · next¶

Your firm's first capability

A named client case study lives here

The platforms above prove the capability. The next case study on this page is a real firm we work with — the one or two AI capabilities we ship together, written up and approved by you before anything is published.

How it startsThe founding cohort works with us free in exchange for a published case study you review first. It begins with the free AI-Readiness Diagnostic.

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