Modulus Code Foundry
Code Foundry leverages three decades of Modulus engineering, millions of lines of fintech source code, proven financial-system architectures, patented technology, and production experience, accelerating the development of reliable, production-ready solutions built on AI.
The structural knowledge frontier models lack
Ask a general-purpose model to build a matching engine and it returns plausible-looking code that misses what actually matters: the order in which components and transactions come together, the failure modes, the protocol nuances, and the operational lessons that never reach public training data.
Modulus Code Foundry carries that missing layer. Trained on our production source code and knowledgebase, it encodes not only what a scalable, production-grade product contains, but the precise sequence, organization, and structure of how it is correctly architected, developed, and maintained, including exchange, marketplace, brokerage, and order management system patterns, market-data and FIX engine know-how, and risk-system design, so code generated by Modulus holds up in the real world.
Modulus Blueprint
Modulus Blueprint™ brings 30 years of financial infrastructure experience into the AI development process, including source code, architecture, implementation patterns, regulatory awareness, testing discipline, trade secrets, and production lessons learned by our engineers.
Modulus Code Foundry™ applies the Blueprint to active development, helping AI-assisted workflows start with stronger architecture, licensed source code, relevant components, financial-system test coverage, and human engineering review. Instead of turning prompts into disconnected code, the workflow is guided by the structure, boundaries, and operational details required for financial technology that must stand up in production.
Production-proven Modulus components may be licensed whenever they can accelerate the project, and applicable Modulus patents may also be licensed. The result is faster development, stronger architecture, clearer IP, better security, and a more reliable path from prototype to production.
Modulus works with your AI
Claude Code, Codex, and similar tools can generate code quickly. The advantage is not the model, but rather the engineering behind it. Modulus brings three decades of source code, trade secrets, architecture, and production lessons into AI development. The result is financial technology built for production, delivered up to 10x faster and more cost-effectively than conventional development.
Connect the Modulus MCP server and give your AI access to Modulus fintech skills, review protocols, and audit checklists covering regulatory, security, performance, architecture, and financial-system risks.
Your code and prompts remain private. Your AI performs the work inside its existing environment and may suggest optional Elastic Work Units when independent engineering or review would strengthen your project.
Two ways to build with Modulus
Choose who performs the work. Your AI can build with Modulus guidance, or a Modulus engineer can handle the job through Elastic Work Units. Use either path independently, combine them, or move between them as your project evolves.
Build with your AI
Connect the Modulus MCP server to your AI development environment. Your AI will receive specialized fintech skills, architecture guidance, source code, review protocols, audits, and recommendations drawn from three decades of Modulus experience, while your code and prompts remain private.
Build with ModulusModulus builds for you
Buy Elastic Work Units for $499 each. A Modulus engineer leverages our Blueprint™ and Code Foundry™ systems to return verified work within 24 hours. Use one unit or run multiple in parallel and scale to a complete platform. No hourly billing or a long-term contract.
Security built into our AI workflow
AI-assisted development opens a new attack surface, and Modulus runs its own AI workflow accordingly: hardened against prompt injection, credential theft, tool poisoning, and privilege escalation, with access scoped to each job.
The same security discipline that has protected real trading infrastructure for more than three decades is applied to our AI workflow, so adopting AI-accelerated development does not mean accepting new risk.
What you get in every Work Unit
If you choose to purchase Elastic Work Units, every deliverable is built on a foundation exclusive to Modulus. Our engineers direct Modulus-tuned AI that leverages three decades of fintech architecture, trade secrets, production lessons, and millions of lines of source code to help identify the architecture, security, regulated-finance, and production risks that generic prompts may overlook.
Production lessons
Three decades of operational know-how encoded into every build.
Proprietary fintech source
Real components from Modulus products, not generic snippets gathered from the open web.
Implementation patterns
How exchanges, matching engines, and trading platforms are built and scaled in production.
Architecture guidance
Design decisions proven under real market load, latency, and regulation.
Human quality control
A Modulus engineer checks every deliverable before it reaches you.
Expert security
Defenses against prompt injection, credential theft, tool poisoning, and privilege escalation.
Keep it running with Production Support
The Modulus Production Support Plan puts the engineers who build and understand fintech on call for your production systems. Markets move at midnight, liquidations cascade on Sundays, and infrastructure fails on holidays. When a trading platform, exchange, prediction market, or other fintech system breaks under live load, you open an incident and a Modulus engineer gets to work within your plan's response target, around the clock or across business days depending on the coverage you choose.
Every incident gets a real diagnosis, not a ticket number: investigation, root cause analysis where the cause can be determined, guidance on mitigation and workarounds, and a written summary of findings and recommendations. Support is advisory by design, so your systems stay in your hands and your credentials stay yours. Where access is needed, it is named, least-privileged, and revocable, and your team executes the changes or expressly authorizes each one.
When a fix requires changing code or configuration, that is development work, and it is handled as a Priority Work Unit that goes to the front of the queue and starts immediately. Support finds the answer; a Priority Work Unit ships the fix. Coverage runs month to month with no setup fees, no annual contract, and no lock-in. See Production Support for plans and full details.
