FAQs

How Modulus builds software for banks, exchanges, brokerages, fintech infrastructure, and more, delivered with AI-accelerated engineering.

What does Modulus do?

Modulus is a financial technology and software engineering firm. Since 1997 we've built, modernized, rebuilt, and rescued trading platforms, exchanges, broker tools, order-management and market-data infrastructure, developer libraries, and AI/HPC systems for banks, brokerages, exchanges, funds, and trading firms worldwide.

What is a Work Unit?

A Work Unit is $399 worth of work performed by Modulus. Send a job description, and a Modulus engineer directing Modulus-tuned AI returns a reviewed deliverable within 24 hours, checked by a human engineer. Not all jobs can be completed in 24 hours, but we'll do our best.

Is a Work Unit 24 hours of work?

A Work Unit is a turnaround window, not a quantity of labor. You buy the deliverable and the deadline, such as one clearly scoped job, and you receive a reviewed deliverable back within 24 hours. How we produce it, with Modulus-tuned AI doing the heavy lifting and a Modulus engineer directing and checking the work, is on us. Each Work Unit returns reviewed work within the stated window, but it does not promise that a larger job or project will be complete in one unit.

How can Modulus deliver this for $399?

Because you are not paying for hours. A Work Unit draws on 25 million lines of production fintech source code, patented infrastructure, 30 years of trade secrets, and AI workcells directed by a Modulus engineer, so the work starts from what we have already built and proven rather than from a blank page. The price reflects what AI-era delivery costs; the output stands on everything Modulus has built since 1997, which is also why raw AI and cheaper operators cannot match it.

Is this just Claude Code or Codex?

No! Anyone can point a coding agent at a task; what comes back is raw output someone still has to check, test, and document. A Work Unit is engineer-directed AI execution: a Modulus engineer directs Modulus-tuned AI powered by our internal Blueprint™ and Code Foundry™ systems, which bring 25 million lines of production fintech source code, architecture patterns, and nearly three decades of production lessons into every job. That is why Modulus-tuned AI is not the same AI everyone else is using. The engineer reviews every deliverable before it ships and answers for the result: the engineer is the accountability, the AI is the performance.

Do you offer free trials?

A Work Unit is the trial: $399, no subscription, no long-term contract, and no minimum commitment. Send one clearly scoped job and receive a reviewed deliverable within 24 hours, so you evaluate Modulus with reviewed work in hand rather than a demo or a sales deck. If the work does not earn the next unit, you stop, and the deliverable remains yours to use under its license.

How fast can you deliver?

A single Work Unit returns reviewed work within 24 hours. You can purchase as many Work Units as needed, to run side-by-side, if your project is large and must be developed as fast as possible.

Do Work Units include revisions or SLAs?

No. Work Units do not include revision cycles, acceptance periods, or ongoing support. If you want changes, continuation, bug review, or additional work after delivery, submit another Work Unit.

Is production support included?

Production Support is available however it is sold separately. See Production Support.

Can I have a web meeting with a developer?

Yes, on a weekly schedule. Clients with more than one active Work Unit meet with their Modulus engineer once each week in a scheduled alignment meeting to review delivered work and set direction for upcoming units. Outside that meeting, Work Units run on written requirements, with no per-unit calls, texts, chats, or email threads; that discipline is how a job that would normally cost thousands stays at $399. If your requirements are not clear enough to execute, we do not spend your unit asking questions. We return the credit before work begins with a written explanation of what was missing, and you resubmit with clearer instructions.

Can Work Units support large projects?

Yes. Work Units support a single job or a full platform build, and they run in parallel under your Modulus engineer's direction, so a ten-unit job does not take ten times as long. A company building an exchange, prediction market, broker platform, market-data product, or financial AI product buys Work Units as needed, pauses when needed, and resumes when ready. See Enterprise Solutions.

Will my job be finished within 24 hours?

Each Work Unit returns reviewed work within 24 hours. Whether that completes your job depends on the job's size. Jobs that fit one unit come back done. Bigger jobs are quoted in units before work begins and return reviewed progress every day until the job is complete.

What if my job is too big for one Work Unit?

Most jobs are, and that's not a problem. Work Units are designed to stack: purchase as many as your job needs, back-to-back or all at once to run in parallel.

Can Work Units replace an entire development project?

Yes, but larger projects usually require multiple Work Units. A small focused job may take one unit. A technical module may take several. A platform-scale build may require dozens or hundreds of Work Units, licensed components, and production support.

What happens if my job is too broad or unclear?

If a submitted job is not suitable for a Work Unit, Modulus returns the credit before work begins with a brief explanation. You can revise and resubmit at no additional charge.

Can a product built with Work Units be sold through Modulus?

Completed products built with Modulus, or existing products integrated with Modulus, may become eligible for Modulus Partner review. Approved products may qualify for Modulus Client Network support, including demos, introductions, and outreach to relevant Modulus relationships.

Are Modulus components included in Work Units?

A Work Unit includes the work: engineer-directed AI execution informed by Modulus source-code intelligence, architecture, and production lessons. Pre-built Modulus components and products, such as matching engines, charting, and connectivity modules, are licensed separately as an option. When a job could be served by an existing Modulus component, we will inform you, because licensing a proven component is often faster than rebuilding one. Components are never required; anything can be built in units instead.

Why license a component instead of build?

Some infrastructure is faster and safer to license than rebuild. Where it makes sense, Modulus provides ready-built solutions that are instantly available, production-proven, and usually cost less than rebuilding them from scratch.

What if we don't want AI used on our project?

Then we build it the way we built financial systems for nearly three decades before AI existed: by hand. Traditional engineering engagements are available for firms that prefer them or whose policies restrict AI tooling, with AI tools limited or excluded entirely and your data-handling requirements honored. These engagements are scoped and quoted individually rather than priced in Work Units; schedule a call to discuss yours.

Will you accept requirements or RFPs generated by AI?

Absolutely. If your team drafted requirements, specs, or an RFP with AI, send them over; we speak that language. We'll turn AI-generated requirements into a real, correctly architected system, delivered as licensed source code with documentation and architecture your team can build on.

Do you work with our existing developers, or only end-to-end?

Both. We're a developer-centric company. We can deliver a complete, turnkey solution, or build alongside your in-house team, taking on the jobs their AI gets stuck on, and handing over clean, documented, licensed code.

Do we get the source code?

Yes. Full source-code access is standard, under a clear license with known provenance. You can audit and extend everything we deliver, no orphan code of unknown origin, no reliance on an unreliable white-label provider, and no lock-in.

Which asset classes do you support?

Equities, options, futures, forex, fixed income, commodities, ETFs, indices, CFDs, and more. Our multi-asset exchange and trading platforms are designed to list and trade an unlimited range of instruments.

How secure is the Modulus AI workflow?

Security is built in. We apply secure coding practices, testing, and in-depth controls designed for financial systems.

Do you offer white-label and custom solutions?

Yes, all of our products are inherently white label. Work Unit deliverables and Modulus products are supplied with full source code, which may be customized to suit your needs and brand. Modulus components are provided under a separate license. We also build custom hardware, from HPC clusters to AI workstations.

Is Modulus's technology patented?

Yes. Modulus holds issued, actively prosecuted patents, cited by JPMorgan Chase, Nasdaq, Capital One, Citibank, Wells Fargo, MicroStrategy, IBM, and others. Patent licenses are available under separate written patent license agreements.
