Shadow Software

One discipline, taken seriously: building software.

No service menu, no upsells. Engagements are scoped per project and run as a fixed-price build or a monthly retainer, with direct access to the founding team. Often that means we build the product another company ships under its own name — our code, their brand.

End-to-end product builds
From an empty repository to a running product: multi-tenant platforms, customer accounts, billing, dashboards, and everything between, owned by the engineers who build it.
Web platforms & APIs
Production web apps and the APIs behind them, built for scale, observability, and a clean handoff to your team.
Integrations & automation
Systems that talk to each other: third-party integrations, data pipelines, and automation that removes manual work.
Architecture & advisory
Technical advisory and architecture review for teams who need senior eyes on the plan before they commit.
Internal tools
Back-office tools and operator dashboards that fit how your team actually works, not a generic template.
