About Opt42

Build useful things.
Understand the system.
Make better decisions.

A founder-led practice connecting systems thinking, engineering judgment, and practical long-term value.

Opt42 brings together Jason Chen's work in software, engineering, investing, and ideas. Across those interests, the question is the same: how can a system work better for the people who use it?

Today, that perspective shapes our workflow assessment, design, and deployment services. The projects and writing collected here show the thinking and exploration behind the practice.

Our Philosophy

Everything can be optimized.
Start by understanding it.

Better tools are only part of a better system. We look at the people, information, decisions, and handoffs together, then ask which change is worth making.

See the whole system.

A faster step is useful only if the overall workflow improves. Understand the constraints and who owns the outcome.

Make the reasoning clear.

Separate evidence from assumptions. Keep uncertainty visible and human judgment accountable.

Bring capital and code together.

Engineering possibility needs economic discipline. Consider the effort, cost, and responsibility of operating what we build.

Improve, measure, repeat.

Begin with a bounded change, learn from its use, and refine it. AI is one possible tool in that process.

The Founder

Meet Jason Chen.

Jason Chen is the founder of Opt42. His work spans embedded systems, mobile software, cloud and AI, and investing. These fields share a need to understand constraints, weigh tradeoffs, and decide what deserves attention. That connection shapes the way Jason approaches workflow improvement.

Projects & Portfolio

Ideas become clearer
when you build them.

These projects explore everyday coordination, financial decisions, and software workflows. Each gives a different shape to the same interest: making a complicated task more understandable and usable.

Projects and demonstrations of capability. Commercialization is on hold; these are not presented as validated businesses.

Agent Runbooks

Give agent workflows a structure.

Agent Runbooks explores how to organize work with AI agents through clear instructions and repeatable steps, making workflows easier to follow and review.

Explores: clear instructions, repeatable workflows, and reviewable outcomes.

POMVest

Give decisions a structure.

Portfolio tools and investment frameworks explore how to organize information and make the reasoning behind a decision explicit. POMVest sits alongside financial modeling and personal portfolio research.

Explores: assumptions, decision rules, and reviewable information.

Fermi

Make the assumptions behind a plan visible.

Fermi brings startup financial modeling into a structured tool. It connects business assumptions to a financial plan, providing a place to examine how different choices shape the model.

Explores: financial assumptions, planning, and scenarios.

FamilyInc

The household as a practical system.

Family life is full of recurring planning and coordination. FamilyInc brings tools for those jobs together, from schedules to checklists, so a broad problem becomes a set of manageable tasks.

Explores: useful defaults, clear interfaces, everyday workflows.
