Applied AI product lab.

Main Character builds AI products and makes existing software more AI-native. Building is how we learn what models can do, what users adopt, and what is worth building.

Operating model

Building is how the lab learns.

  1. 01

    Build

    Make products and prototypes instead of only studying AI from the outside.

  2. 02

    Learn

    Use hands-on work to see what models, tools, and users actually do.

  3. 03

    Reuse

    Carry forward the product patterns and technical pieces that prove useful.

Building is the research method.

Working directly with current models, coding tools, and users gives better signal than watching from the outside.

The lab shows what is newly possible, what still breaks, and what people actually use.

The same work informs Gabe's own AI investing and conversations with founders, operators, and investors.

Selected projects

Work across consumer AI products, model audit tools, agent architecture, and frontline software. Different surfaces, same lab pattern: build, learn, and keep what proves useful.

These are selected public examples, not an exhaustive project history. Some related systems, client implementations, and reused patterns remain private.

AlignTrue

AlignTrue is an open-source reference architecture for supervised AI systems that need durable receipts, replayable state, governed actions, and fenced side effects.

Capabilities

The reusable parts of AI product work: interfaces, context, evaluation, workflows, review, and handoff.

AI products

AI modernization

Durable context

Workflow automation

Model evaluation

Human review

Product interfaces

Deployment handoff

How we work

Small teams, clear constraints, fast loops. Build narrowly, validate with real use, and leave behind software that can be maintained.

Build the thing

Make real product surfaces, test them with real constraints, and let the work show what matters.

Learn from use

Pay attention to where AI helps, where it fails, and how people change their behavior around it.

Keep what holds up

Turn repeated patterns into clearer product architecture, reusable tools, and better judgment for the next build.

AI projects

Some projects become products. Some become reference architecture. Some become private tools or collaborations. The point is to build close enough to the technology to learn from it.

Good projects have users, workflows, data, feedback, and a reason to improve over time.

We are open to selected collaborations when the work is concrete and the learning is real.

Products built around AI

Existing product modernization

Durable context and memory

Evaluation and model behavior

About the team

Main Character is founder-led by Gabe Mays. It is a place to build AI products, learn from the work, and collaborate when there is a concrete project to build.

Before Main Character, Gabe led product teams at GoDaddy and built products across SaaS, automation, developer tools, and AI systems. Before tech, he served as a Marine Corps Captain with deployments to Iraq and Afghanistan.

The lab also informs Gabe's own AI investing and conversations with founders, operators, and investors. The common thread is firsthand product signal from building with the technology.
