The brief
The problem
Outbound teams juggle a dialer, a CRM and a notes app while trying to stay compliant. Off-the-shelf contact-center software is expensive, rigid about workflow, and usually adds AI as a separate feature.
What we did
Our approach
We are building our own contact center end to end: calling, campaigns, agent views and the contact record in one product, with a private assistant for each user that helps before, during and after the call. Web and native apps share the same backend. Calls are held to a calling window in each contact's timezone and checked against an internal do-not-call list.

Developer ToolsJarvisMCP
JarvisMCP gives AI agents one governed door into our company systems: CRM, search intelligence, infrastructure, memory and coordination. Agents find the capability they need, act through it, and leave a record. They never hold the keys.

Business SystemsButlerCRM
ButlerCRM keeps contacts, deals, email, calendar and tasks in one workspace that updates live for everyone in it. We rebuilt it on Elixir/Phoenix so changes appear for the whole team as they happen.

How we work
How a change reaches production
The same five gates for our own products and for yours. Nothing reaches your customers on the strength of a demo.
- 01 · Isolate
Its own branch and workspace
Every change starts in a separate copy of the code, so work in progress never touches what is live.
git worktree add .worktrees/your-change - 02 · Build
Engineers with AI agents
Agents write and test code beside us. They hold no passwords: every call they make goes through our gateway, which checks it and logs it.
agent → gateway → policy · audit · call - 03 · Prove
Evidence, then review
Tests, before-and-after screenshots of the running app, then independent reviewers. It does not move on until no serious finding is left.
review: 0 high · 0 medium → pass - 04 · Ship
Deployed and checked live
The pipeline builds and deploys. Then we check the running service itself, not just a green build.

Checked every night
Each integration we run is tested against its provider every night, so a changed API is caught before your team notices.
