Case studies

Systems in production, with the numbers behind them.

AI systems built for operations-heavy teams, inside the tools they already used. Client names stay private; the results are below.

Customer supportProperty operator, 5,000 units

An AI support agent that handles 10,000+ tickets a month

First response went from over a day to under two minutes, with the agent working each ticket from first message to close, around the clock.

The problem

Hundreds of tickets a day arrived across guest messages, SMS, email and internal apps. First response took more than 24 hours, and most of the process lived in people's heads rather than in writing.

What we built

  • An agent that works each ticket end to end in chat and voice: answers, status updates, check-in help and follow-ups
  • Answers grounded in the client's own SOPs and knowledge base
  • Work orders created automatically, with category, priority and unit already filled in
  • An escalation engine that weighs confidence, off-topic requests, edge cases and sentiment before handing off
  • Hourly health checks that raise an alert the moment anything stops

The result

The team no longer triages the inbox by hand. Routine tickets close without a person, and anything uncertain reaches a human with the full context attached, because an escalation is always better than a bad answer.

OperationsEstablished company, several teams

AI systems that took manual work off several teams at once

Team capacity rose about 35% in under two months, and one set of systems alone removed $50k+ a year of manual work.

The problem

Back-office teams spent a large part of every week checking, matching and re-keying documents by hand, and they wanted AI built into their daily work rather than one more tool to log into.

What we built

  • Document-processing pipelines that read and check incoming paperwork
  • Reconciliation tools that match records across systems automatically
  • AI assistants connected to internal systems and data through custom connectors
  • Customer-facing AI assistants built into the company's products
  • Hands-on rollout with each team so the tools became part of the routine

The result

Capacity went up about 35% in under two months. The document and reconciliation systems, delivered in about six weeks, removed $50k+ a year of manual work on their own, and they are only one part of what was built.

SalesMultifamily operator, B2B sales team

A prospecting engine that hands sales a ready-to-work list for every market

Prospecting the team used to do by hand now runs as a pipeline, saving about $170k a year in staff time and adding six figures of new pipeline.

The problem

The sales team spent most of its week prospecting by hand, stitching property data, a contact database and the CRM together before a single message went out.

What we built

  • Property data pulled from CoStar, then segmented and scored by fit
  • Contact enrichment through ZoomInfo
  • A custom-object HubSpot setup, loaded automatically
  • Owner and manager lists for the top 20 metro areas, ready for outreach

The result

Sales starts the week with scored, enriched contacts already in HubSpot and spends its time on conversations instead of research. The lists have already opened six figures of new sales pipeline.

Product buildHome services startup, live users

A home maintenance concierge, built from concept to production

Homeowners text one number, and an AI that remembers their home handles reminders, troubleshooting and booking a vetted pro.

The problem

Most homeowners only service their equipment once something breaks, and then they are left searching for a contractor and hoping the one they find is reliable.

What we built

  • An SMS concierge that remembers every system, appliance, install date and service record in the home
  • Maintenance reminders timed to the actual equipment
  • Troubleshooting that tells a quick DIY fix apart from a job for a licensed pro
  • Vendor scheduling, dispatch and payments
  • A web app, plus a dashboard for partner businesses

The result

The platform went from an idea to production with live users, and it runs entirely over text, so homeowners never have to install an app.

HealthcareHealthcare software company, clinic network

One booking layer for clinics that all run different software

Voice and chat agents book appointments across clinics on different scheduling systems, through a single interface.

The problem

Clinics run on many niche practice-management systems, each with its own API, so every new clinic meant another custom integration before an agent could book anything.

What we built

  • A master MCP server in n8n that routes each request to the right system adapter
  • Per-clinic settings stored in Supabase, so adding a clinic is configuration, not new code
  • Voice agents on ElevenLabs and chat agents in n8n that book through it
  • A patient billing form and a payment agent connected to the clinic CRM

The result

Agents book through one shared layer instead of one integration per clinic, and patients get answers by voice or chat at any hour.

Voice

After-hours voice agent for a specialist medical practice

Picks up the calls and texts that used to go to voicemail, qualifies the caller, explains the consultation fee and books them with the right provider.

Sales

Voice-to-CRM for a field sales team

Reps update the CRM and send follow-up emails by talking to an agent between meetings. Now growing into automated lead enrichment and outreach drafts.

Reporting

Reporting automation for a multi-location franchise

An unattended cloud worker pulls weekly coaching and ad performance data from a locked-down dashboard and checks every figure against the raw export before a report goes out.

Voice

Missed-call agents for local service businesses

Voice agents that answer missed and after-hours calls for trades and clinics, capture the lead details, alert the owner and start an SMS follow-up.

Next step

We should probably talk.

Thirty minutes to test whether there is enough operational leverage here to justify an audit. If the honest answer is that there is not, you'll hear that too.
