The messy things, handled.
What we build
Find the awkward part of your business, build the thing that fixes it, hand it over. Each of these is real work.

Stop doing the paperwork by hand
- Order acknowledgements sent automatically from a distributor's ERP
- Remittances reconciled against the bank
- Live contract pricing, straight from the ERP
Put AI to work, and teach your team to use it
- A product assistant that answers from live inventory
- An AI customer-service agent inside HubSpot's chat
- Training for sales reps, owners and managers

Connect the systems you already pay for
- Shopify apps for warehouse integration
- HubSpot tasks in Outlook, which became taskCNX
- Logistics processing tools for a national print services provider
Build the apps and websites your customers see
- iPhone and Android apps, from a band's fan app to single-purpose tools
- Sites that say what a business does in the first screen, like this one
- Sites built behind the scenes for design firms and their clients
OneRepublic Official Fan App
Built for the band's global fanbase, on iPhone and Android. The same care goes into a tool that only your team will ever see.
Built and run end to end: the app fans use and the admin the band's team works from.

crewCNX
Your AI staff. Your rules. Crews of AI agents do the routine work, and a person approves what goes out.
Each agent has one job and only the access that job needs. These crews run every day inside a distributor's ERP and CRM:
- Finance: payments matched, exceptions flagged.
- Order desk: about 3,300 vendor emails a month turned into ERP updates.
- Sales desk: your ERP, in plain English.
- Customer service: customers answered from live stock.
Marketing, operations and inbound crews are built with you.
Custom agents and crews welcome.
See crewCNX →taskCNX
Start small. One-person small. HubSpot tasks in Microsoft To Do, free.
It began as a fix for one sales team. Reps work their HubSpot tasks from Outlook, and a checkmark there completes them in HubSpot. Seats bill only when someone connects.

Single-purpose apps for iPhone, four also on Android. No subscriptions, no tracking.
