For leaders weighing high-stakes changes

Why does every software decision feel expensive?
Harmony shows what the change touches before you commit.

Hidden coupling and quiet dependencies only surface after work begins. Harmony exposes the blast radius up front, so you can choose the option you can actually defend.

Every software decision feels expensive

Because nobody can see the full impact before the change is made. Harmony maps the blast radius up front so you choose the option you can actually defend.

Compare options honestly

Rewrite vs refactor vs contain — with the technical implications spelled out next to each path.

Estimates that hold

Surface the hidden coupling that normally shows up halfway through delivery and breaks the plan.

Who this is for

For decision-makers about to authorize a change they can’t easily walk back.

Engineering leaders planning a migration

You're weighing rewrite vs. refactor and need to see the blast radius before you commit.

M&A and acquisition teams

You're evaluating a target and need to know what you're buying — and what changing it will cost.

New CTOs / VPs of Engineering

You inherited a complex system and are accountable for it. You need a defensible picture before making big calls.

Founders & early CEOs

Your team built it. You're accountable for it. You need to understand it without slowing them down.

PE & VC operating partners

You need a fast, defensible technical read on a portfolio company — without booking weeks of interviews.

Product & business leaders

You need a board-ready view of the system without becoming the technical translator.

Before you commit

Frame the change

Tell us the move you’re considering: a rewrite, a migration, a deprecation, a consolidation.

We trace the impact

Harmony walks the dependencies and surfaces what’s coupled to the area you’re about to touch.

Commit with confidence

Walk into the steering committee with a board-ready brief, a system map, and an honest cost picture.

Common questions

Do you train on our code?

No. Code is processed for analysis only and is never used to train models.

What do we need to share to get started?

A repository — GitHub, GitLab, Bitbucket, and Azure DevOps are all supported. Zipped sources work too.

How fast do we see something useful?

First brief lands in days, not quarters. Most teams have a board-ready view within 48 hours of connecting a repo.

Stop paying for surprises after the fact.
