We build what founders dream.
AetherCraft is a product studio for the obsessed. We partner with founders, entrepreneurs, and business owners to transform ambitious ideas into market-defining products. Every engagement is led personally by founder Eduardo Diaz.
A product studio, not a software agency
A software agency builds what you spec. A product studio helps you figure out what to spec. We contribute product strategy, UX design, and full-stack engineering together — acting as a co-founder-level technical partner who shapes what gets built, not just a vendor who executes. We work with a small number of clients each year so quality and founder attention never get diluted.
What we build
- MVP development — the smallest version of a product that proves real value.
- SaaS development — cloud-hosted, subscription software built to scale.
- Custom software development — software built around your exact workflows.
- AI-powered software — machine learning and LLMs embedded in real products.
- What is a product studio? — how we work and why it's different.
