What we do

Two people. You talk to the people doing the work.

Business planning and strategy

What to do next, in what order, and what it will cost.

Starting a business

We've done it ourselves. The setup, the order of operations, the first customers.

Design and marketing

Websites, marketing, logos, and digital assets, drawn in Inkscape.

Systems and project planning

Workflow systems, schedules, roles, culture, and remodel and project plans, so the work doesn't live in one person's head.

Creative problem solving

When something is stuck, we work out why and what to try next.

AI training and custom tools

Hands-on training for you or your team, and tools built for one job. Only where they save real time.

Businesses we built

Two we started, and two we built with Otto. We also do tool, digital-asset, and consulting work for other working businesses, and we keep their names private.

HOW WE USE AI

AI doesn't replace the expert. It makes you a better partner to one.

You keep the judgment. That's how we build tools, and how we teach.

Tools we've built include a landscaping visualizer, Carbon tattoo stencils, a ghostwriter, a legal explainer, and a bid-proposal builder. Each one says what it is and what it isn't. Try the free tools

High Carbon Consulting is two brothers, Tim and Otto Arnesen. No account managers. The two of us do the work.
