Powering the most ambitious Canadian companies.

We've built alongside founders in some of the fastest-growing companies in Canadian history like Hootsuite, Avigilon and BioRender.

Our roots are in software companies backed by a16z, Accel, OMERS and Y Combinator — we know how to solve hard problems at scale.

Delivering on the hardest engineering challenges.

Our Approach

How we build

Proven approach for the most unforgiving domains.

⁰¹ Architect

We design systems that leverage state of the art research to meet hard demands of constraint, scale and performance.

⁰² Build

Software and infrastructure for the cloud, the field, or anything in between. We build applications, platforms, and interfaces that perform under pressure.

Offline-first apps

Edge & forward-deployed

Ingestion pipelines

Small LLMs & Fine-tuning

Operator interfaces

⁰³ Verify

Alongside conventional software quality assurance, we incorporate model checkers and system specifications like TLA+ to build provably correct systems.

⁰⁴ Secure

Resilience and fault tolerance under extreme operational constraints. We simulate degradation, denial, and attack using advanced emulation techniques.

Threat-based hardening

Supply chain resilience
