The runtime and the agents for the AI-native era

DETIR_ARTH makes apps agent-operable. AiStack runs your business systems with agents. One stack, built to last.

The Splenta products

Everything to build and run AI-native systems — the runtime, the apps, and the agentic stack. All invite-only.

Foundational

A purpose-built systems language with ownership, borrowing and a pluggable runtime substrate — the language Detir runs on.

VM, JIT & native

One front end, three backends — bytecode VM, Cranelift JIT, LLVM AOT.

Memory-safe by construction

Compile-time ownership and borrowing with inferred lifetimes.

First-class tooling

LSP diagnostics, a formatter, and a TypeScript front end.

Infrastructure-first

We build foundational architecture before surface features. Agents are in the loop by default; people step in only when it matters. Every system is designed to be extended, audited, and run for years.
