Do more.
Do less
busywork.

I'm Jacob. The Vault AI builds the systems that let a business run on fewer people doing less repetitive work — websites that actually convert, AI that answers your phone, software that replaces the fifteen apps your team toggles between. One engineer, an AI-native build process, and real things you can click through below before you hire me.

Track record

Real projects. Real clients. Real systems running.

From GSIB-bank treasury operations to the City of Charlotte's 311 system to Charlotte small businesses — same playbook, different scale. No marketing-team case studies.

Forecast-Over-Forecast Delta Finder & Explainer

How I work

If you can describe
the problem,
I can build the software.

I don't do enterprise procurement or 12-week discovery phases. You describe the problem, I quote a price, we ship it. The Vault AI grows with the field — every new model, every new technique becomes a tool I bring to your business.

Industry doesn't matter. If the problem is real, I can probably help.

Websites & landing pages
Built to convert, not just to look nice in a portfolio.
Business automation
Email sequences, scheduling, invoicing, notifications — the repetitive stuff off your desk.
AI trained on your data
Chatbots, document processors, internal copilots. Not a science project.
Custom apps & dashboards
When off-the-shelf tools don't fit your workflow.
System integrations
Connect the apps that don't talk to each other: CRM + accounting + calendar + whatever else.
Private AI infrastructure
On-premise AI for industries where data can't leave your building — law, healthcare, government, finance.

Who I am

Jacob Krzeminski

I run The Vault AI out of Charlotte, NC. I build the systems that let a business do more with less busywork — websites, AI phone agents, automations, dashboards, and case-management software. AI is my development engine, which means I ship what used to take an agency six months in three to six weeks, for a fraction of their price. I'm not hiding it. It's how I compete.

I work with restaurants, law firms, healthcare practices, city governments, real estate brokers, contractors — anyone with a problem they've been putting off. Industry doesn't matter. Whether it's tech, ops, marketing, or internal tooling — if the pain is real, I can probably help.

I don't disappear after delivery. I don't hand your project to a junior. Every build gets my direct attention from kickoff to launch — and I stand behind it after.
