Invent. Build. Iterate.

Coreledger builds practical, developer-first AI products. Contextus cuts waste from LLM context so teams ship faster and spend less. Now you can get sharper results at a fraction of the cost.

What we build

We focus on foundational technologies that power the next generation of intelligent applications

Context & Data Models

Structures that keep facts straight and relationships intact, so your AI answers with context, not guesses.

AI Tooling

SDKs and APIs that plug into your stack in minutes, not months. Now you can optimize GPT or Claude without upgrading models.

Production Foundations

High-performance pipelines, observability, and guardrails that scale from a single dev to the whole org—without surprise costs.

Featured Product

Contextus

Your AI scalpel that cuts token costs by 40% without upgrading your model. LLMs have a memory cap, the context window. Every extra token costs money and risks drift or hallucination. Contextus helps your AI prioritize what matters & discard the rest, allowing developers and teams to save 40 percent while improving accuracy.

From fintech to frontier tech

How we got here & why we're obsessed with reliability.

2019–2024

Fintech Foundation

We built for regulated markets: matching engines, reconciliation, and hard data problems. It taught us discipline, accuracy, latency, and cost control.

2025+

Technology Studio

We’re applying those muscles to AI. First with Contextus, then a suite of developer tools that make large models practical in production.

Built by engineers, for engineers

We’re product-minded engineers. We ship, measure, and shave off the rough edges until it works in the real world. Our fintech years trained us to value correctness and cost, so every tool we build helps teams move faster and trust the output.
