Building the Infrastructure for Tomorrow's Financial Systems
Fire Build is a US-based software development company that specializes in creating mission-critical systems for digital assets, payments, capital markets, artificial intelligence, and deep technology. We partner with institutions that demand excellence, security, and scalability.
Deep Expertise Across Critical Domains
We focus on areas where software complexity meets high stakes—where systems must be secure, compliant, and built to withstand the demands of institutional-scale operations. Our specialized knowledge allows us to deliver solutions that general-purpose development teams cannot.
We build the foundational infrastructure that powers digital asset ecosystems. Our expertise spans custody solutions, tokenization platforms, blockchain integration layers, and compliance frameworks. From exchanges to institutional custody, we architect systems that handle billions in digital value with the security and reliability that regulated entities require. We understand the unique challenges of building in this space—managing private keys at scale, ensuring transaction finality, and navigating complex regulatory landscapes across multiple jurisdictions.
Payment systems are the arteries of modern commerce, and we specialize in building the infrastructure that keeps them flowing. Our work encompasses real-time payment networks, cross-border settlement systems, payment orchestration platforms, and card processing infrastructure. We have deep experience with the technical intricacies of payment rails—from ACH and wire transfers to instant payment schemes and emerging payment methods. Every system we build is designed for the extreme reliability, throughput, and fault tolerance that payment processing demands.
Capital markets technology requires a unique blend of performance, precision, and regulatory awareness. We develop trading systems, order management platforms, risk management solutions, and market data infrastructure for institutional clients. Our engineers understand the microsecond-level performance requirements of modern trading, the complexity of multi-asset class platforms, and the regulatory reporting obligations that govern financial markets. We build systems that can handle market volatility, scale during peak trading periods, and maintain complete audit trails.
Artificial intelligence is transforming every industry, and we help organizations harness its potential responsibly. Our AI practice focuses on building production-grade machine learning systems, large language model integrations, computer vision applications, and intelligent automation platforms. We go beyond proof-of-concepts to deliver AI systems that operate reliably at scale, with proper monitoring, governance, and human oversight. We specialize in the challenging engineering work of deploying AI in regulated environments where explainability and auditability are paramount.
Some problems require going deeper than conventional software development. Our deep technology practice tackles challenges in distributed systems, cryptography, high-performance computing, and emerging computational paradigms. We work on problems like building consensus mechanisms, designing secure multi-party computation protocols, optimizing systems for specialized hardware, and architecting solutions for edge computing environments. When standard approaches fall short, our team has the expertise to develop novel solutions from first principles.
Built for Organizations That Cannot Afford to Fail
We work with institutions where software reliability is not optional—where downtime means financial loss, regulatory scrutiny, or erosion of public trust. Our clients choose us because they need a partner who understands the weight of what they're building.
Banks & Financial Institutions
We understand the unique constraints of banking technology—legacy system integration, regulatory compliance, operational resilience requirements, and the scrutiny that comes with handling customer deposits. Our team has built systems for institutions ranging from community banks to systemically important financial institutions. We know how to navigate procurement processes, work with internal technology teams, and deliver solutions that pass rigorous security and compliance reviews.
Fintech Companies
Fintech moves fast, and we match that pace without sacrificing quality. Whether you're a Series A startup building your core platform or a scaled fintech optimizing for growth, we bring the technical depth to accelerate your roadmap. We've helped fintechs launch new products, achieve regulatory approvals, scale infrastructure for hypergrowth, and prepare for technical due diligence. Our experience across the fintech ecosystem means we understand the common patterns and pitfalls.
Enterprises
Large enterprises face distinct challenges when building sophisticated software—coordinating across business units, integrating with existing technology stacks, and managing the organizational complexity of major technology initiatives. We've delivered enterprise-grade solutions for Fortune 500 companies, bringing the technical excellence of a specialized firm with the professionalism and reliability that enterprise engagements require. Our teams are experienced in enterprise governance, security frameworks, and the documentation standards expected at scale.
Government & Public Sector
Government technology projects carry unique responsibilities—to taxpayers, to citizens who depend on services, and to the public trust. We approach government work with appropriate gravity, building systems that are secure, accessible, and designed for long-term maintainability. Our experience includes federal financial systems, state-level modernization initiatives, and projects requiring security clearances. We understand government procurement, compliance requirements like FedRAMP, and the accountability standards that public sector work demands.
How We Work
We believe that exceptional software comes from a combination of deep technical expertise, genuine partnership with our clients, and an unwavering commitment to quality. Here's what that looks like in practice.
We Start by Understanding
Every engagement begins with deep discovery. We invest significant time understanding your business context, technical landscape, regulatory environment, and strategic objectives. This isn't a perfunctory kickoff—it's the foundation that ensures everything we build serves your actual needs. We ask hard questions, challenge assumptions, and work to understand not just what you want to build, but why.
This understanding extends throughout the engagement. We maintain close communication, share context broadly within our team, and continuously refine our understanding as projects evolve. We believe that misalignment is the root cause of most failed technology projects, and we work actively to prevent it.
We Build for the Long Term
The systems we build are designed to outlast our engagement. We write code that your team can understand, maintain, and extend. We document thoroughly—not as an afterthought, but as an integral part of delivery. We make architectural decisions that favor clarity and maintainability over clever solutions that only we understand.
We also plan for knowledge transfer from day one. Whether you're building an internal team to take over, working with us on an ongoing basis, or planning for eventual handoff to another vendor, we structure our work to enable smooth transitions. The goal is never to create dependency—it's to create capability.
We Take Security Seriously
Security isn't a feature we add at the end—it's a property we design for from the beginning. Our engineers are trained in secure development practices, threat modeling, and the specific security requirements of financial and government systems. We implement defense in depth, follow the principle of least privilege, and build systems that fail safely.
We also understand that security extends beyond code. We maintain strict access controls within our own organization, conduct background checks on our team members, and can work within the security frameworks that our clients require. When security incidents occur in the broader ecosystem, we proactively assess and communicate any implications for our clients.
We Communicate Transparently
We believe that good surprises in software projects are rare—most surprises are bad. Our communication style is proactive and honest. When we encounter problems, we surface them immediately. When timelines are at risk, we say so early. When we think a client is making a mistake, we share our perspective respectfully but clearly.
This transparency extends to how we work. Our processes are visible, our progress is measurable, and our reasoning is documented. We don't hide behind complexity or jargon. If something doesn't make sense to you, that's our failure to explain, not your failure to understand.
