01Manifesto
Most software fails in the same place: the moment it meets real users, real money and real load. We build for that moment first, and let the demo follow.

03What we do
Three practices, one engineering team.
Most engagements cross more than one. A payments product needs contracts and a plan tier. An automation platform needs a queue and a console.
- 001 / Chain
Ship onchain systems that hold real value.
For protocol and product teams who need contracts, oracles and wallet flows that survive audit, adversarial users and real money.
- Smart contracts
- Oracles and DeFi
- Token systems
- Full-stack dApps
- 002 / Product
Build the platform, not another prototype.
For founders and operators turning a validated idea into a multi-tenant product with billing, roles and a data model that still works at the tenth customer.
- Multi-tenant SaaS
- Web and mobile
- Payments and plans
- Brand sites
- 003 / Automation
Put the model behind a system that can be trusted.
For teams that want language models doing real work: grounded generation, message automation and data pipelines with guardrails, queues and audit trails.
- Grounded generation
- Agent systems
- Messaging bots
- Data pipelines
04Selected work

Bring the hard part.
Contracts, multi-tenant data models, queues that cannot lose a message. Tell us what has to work, and we will tell you how we would build it.
