Maru Systems · Greenwich · Connecticut

Operations,
tailored.

Custom POS, inventory, AI agents, and brand-matched commerce · wired into every app your team already uses. Built end to end for the kind of business that refuses to bolt onto someone else's stack.

A statement of approach

Most agencies sell templates dressed in your colors.
We don't.

Every system we ship is shaped to the way your people work, in your voice, on your brand. The receipts, the inventory tags, the AI agents your team actually talks to · all of it built for one specific operator and shipped to it alone. No white-label. No retainer-and-pray.

We use AI generously, but never as the headline. Real ops, real checkout, real workflows · wired into every tool your team already opens daily. The intelligence is invisible until you ask. Then it gives you the answer, the export, the email, the next move.

Capabilities

Three lines of work,
braided together.

Each engagement starts with what hurts most · then we extend outward. By the time we're done, the three look like one system that nobody else has.

01

Operations

Custom POS, inventory, scheduling, repairs, payables, fulfillment · the unglamorous machinery your business runs on. Brand-matched receipts, ticket printing, document automation, the whole apparatus.

  • ·Custom POS · pay-by-link, terminal validation, multi-payment splits
  • ·Inventory · barcoded SKUs, consignment-aware, multi-location
  • ·AI receiving · vendor docs to clean rows in 30 seconds
  • ·PDF automation · invoices, warranties, quotes, contracts
02

Intelligence

AI agents that know your customers, your inventory, your data · and only yours. Agentic workflows that act across your stack: read the inbox, draft the reply, update the CRM, ship the proposal, log the call. Branded voice. Persistent memory. Role-aware.

  • ·Custom concierge · trained on your data, in your voice
  • ·Customer profile synthesis · who hasn't visited, who's worth a call
  • ·Action agents · email · calendar · CRM · accounting · all wired
  • ·Proposal & quote generation, custom Excel & PDF exports
03

Web

Storefronts, dashboards, marketing sites, internal portals · whatever the brand needs to show the world. Quiet typography, real performance, a checkout that feels like the rest of you.

  • ·Brand systems · type, palette, ornament, voice
  • ·Storefront + appointments + Stripe / Square / Adyen
  • ·Internal admin consoles · role-based access, audit trails
  • ·Resend / DNS / OG / SEO · the quiet plumbing done right

Beyond a single vertical

Any business that runs on a counter, a calendar, or a workflow.

The architecture we ship doesn't care what industry sits on top of it. It cares about how your team books, sells, fulfills, invoices, and follows up · and how all of that talks to the rest of the tools you already pay for. Below is a partial map of verticals we've scoped or shipped for · the underlying spine generalizes further.

Concept · custom slate countertop console with edge-lit chassis · tailored hardware in development with select clients.

Custom on the inside. Connected on the outside.

The system runs deep, but it doesn't live alone. Whatever your team is already opening daily · we wire it. The software disappears into the operation instead of fighting it.

Integrations

Wired into every major app.

Direct API integrations, webhooks, MCP servers, and unified connector layers (Composio, Pipedream, n8n) when speed matters more than reinventing the adapter.

Composio

· agent fabric

250+ apps available to your AI agents from day one.

When we build agents on your data, we wire them straight into Composio · so your concierge can read Gmail, draft a Slack message, update a Salesforce contact, file a Linear issue, ship a HubSpot sequence, log time in QuickBooks, post to Notion, book on Calendly, and pull a Stripe receipt · in the same conversation. No glue code per app. Hundreds of integrations, governed and audit-logged, ready the day we hand the keys over.

If your stack isn't in the catalog yet, we ship the connector. Custom adapters · OAuth flows · webhook plumbing · all in scope.

Method

How a real engagement unfolds.

  1. I.Listen

    Walk the floor.

    We start in your space, with your people, watching how a sale actually closes. The brief comes second · the hour at the bench comes first.

  2. II.Build

    Two weeks to a working spine.

    By the end of the first sprint you have a system you can ring a sale on. Not a wireframe, not a slide deck · a real running tool, in your voice, on your domain.

  3. III.Extend

    Then the rest of the iceberg.

    AI, brand, web, payables, repairs, the customer-facing storefront · we add what's earned, in the order that makes the next sale easier. We stay until the system runs without us.

Anatomy of an engagement

What a finished system looks like.

Names withheld. Every line below ships in the box · branded, documented, owned by the client.

The product is the operating system of a maison · quiet, branded, built to be lived in.

“Built to feel like an extension of the maison · not a bolt-on.”
