A moat competitors can’t cross.
Letco is built on subscription CLIs, not pay-per-token APIs — a structural cost advantage plus free R&D leverage, compounding into a moat that widens over time.
Pay-per-token API
Every token generated costs the platform, and the cost is passed to the customer. Scale means higher bills, API changes mean engineering work, and no flat-cost model is possible.
Subscription CLIs
Built on Claude, Gemini, Codex and Grok subscriptions. Flat cost regardless of tokens, customers can bring their own, and the platforms improve themselves — Letco inherits every upgrade automatically.
Structural Cost Advantage
BYO-subscription model — customers bring their own AI subscriptions. No API pass-through tax; usage is metered and fully transparent per session.
Free R&D Leverage
The AI labs invest billions annually. Letco inherits every upgrade automatically — we don’t build AI, we orchestrate the best AI available.
Architectural Lock-In
Tools built on pay-per-token APIs would need a rewrite, not an upgrade. CLI-first orchestration is a foundation — and this moat widens over time.
5× Seat Expansion
Developer-only tools cap at engineering headcount. Letco scales with the whole SDLC team — a structurally larger market per customer.
A Widening Governance Moat
Anti-drift spec governance keeps AI output aligned with the original intent — while the rest of the industry drifts toward editable “living” specs. This durable layer is the moat that widens over time.
