Custom software,
built to spec
Production-grade web and backend systems engineered for your exact workflow — by senior engineers, when off-the-shelf software doesn't fit.
Custom software development means writing the application around your business instead of bending the business around a tool. We take on bespoke software development for teams whose logic, scale, or compliance load has outgrown a packaged product, and we also build SaaS products end to end when the software itself is what you sell. If you're sizing the investment, custom software development cost breaks down what drives the price, and enterprise software development covers the integration and compliance load that comes with scale.

Production systems built to spec across nine years, type-safe end to end and kept running after launch.
100+
Custom systems across fintech and the enterprise, built to spec and run long after the first release.
6–12wks
From a scoped brief to a production release.
100%
Senior engineers on every build; no juniors learning on your systems.
99.9%
Across the systems we build and operate.
Build the system your product has outgrown
Senior engineers, type-safe end to end, from scope to production.
Custom software across
the full stack
One senior squad across every layer a real system needs — not a single layer handed off between teams. Most engagements touch several of these at once.
Web applications
React and Next.js apps, internal dashboards, and customer portals with the performance and accessibility to ship to production.
Backend and APIs
Type-safe REST and GraphQL services, durable data models, and the business logic that is the actual product.
Enterprise systems
Workflow engines, billing, and back-office logic for organizations where the process itself is the moat.
Integrations
Identity, payments, ERPs, and legacy systems wired together so the new software fits the stack you already run.
Data platforms
Pipelines, analytics, search, and reporting that turn operational data into something the business can act on.
Cloud and DevOps
AWS or GCP infrastructure, CI/CD, and observability built in from day one, so releases are routine rather than events.
Custom software,
by industry
The hardest part of custom software is rarely the code — it's the regulation, the legacy systems, and the edge cases specific to your field. These are the industries where we've shipped to production and stayed on after launch.
Fintech
Ledgers that have to reconcile, payment rails that can't drop a transaction, and audit trails a regulator will actually read. We've built trading and lending platforms where a rounding error is a real incident.
Healthcare
Clinical and patient-facing systems where HIPAA, HL7/FHIR, and uptime aren't negotiable. The work is as much about safe data flow between systems as it is about the screens clinicians look at all day.
Logistics & supply chain
Real-time tracking, routing, and inventory that stay accurate while orders, carriers, and warehouses all change state at once. Most of the build is keeping a dozen external systems in sync.
Retail & e-commerce
Storefronts, order management, and the back-office logic behind them — built to hold up when a promotion sends ten times the usual traffic at checkout.
Insurance
Underwriting, policy administration, and claims workflows where the business rules are intricate and change often, so the software makes those rules easy to edit instead of hard-coding them in.
Legal & RegTech
Document-heavy, evidence-grade systems where every action needs a defensible record. We've shipped legal-tech platforms where the audit log is the product, not an afterthought.
An AI-native
software delivery loop
Custom systems carry business-critical logic and usually can't be thrown away, so we build them with senior engineers in control of every decision and AI tooling removing the busywork.
Discovery
We pin down the problem, the users, and the smallest scope that proves value. AI accelerates research; the decisions stay human.
Architecture
Senior engineers design the data model, APIs, and cloud-native architecture up front. AI drafts boilerplate; humans own the trade-offs.
Build
Full-stack development on TypeScript, Node, and Go with AI pair-programming in the loop — every line reviewed by people.
Quality
Tests, type safety, and CI gates generated and maintained with AI assistance, so regressions are caught before they reach a branch.
Ship
Deploy behind feature flags on AWS or GCP, with observability and rollback wired into the pipeline. A release is a small, reversible step you can run any day of the week.
Operate
Usage data, monitoring, and a senior team on call. We harden and extend the system after launch, not just at it.
Custom systems we
shipped with partners
From regulated fintech to clinical platforms and legal-tech — selected products where senior engineering met a real production deadline.
Neobank and digital banking platform we designed and built
An eco-positioned neobank and digital banking platform that puts accounts, loans, financial advice, and budgeting in one app, designed and built end to end for a younger audience that never visits a branch.
eIDAS-qualified e-signature platform with KYC & blockchain audit
One platform to sign agreements, verify identities, and collect payments, all eIDAS-qualified with a blockchain audit trail on every signature.
Medication management software for patients and care teams
Medication management software with two sides, an accessible patient app and a clinical adherence dashboard, joined by bidirectional HL7/FHIR EMR sync.
Custom software
questions
What founders and product teams ask before starting a custom software engagement.
Custom software development is the design and engineering of an application built specifically for one organization's requirements, rather than a configurable off-the-shelf product. It spans the web front end, the backend and APIs, the data model, and the integrations a business depends on — built to spec when the logic, scale, or compliance needs don't fit a packaged tool.
Off-the-shelf SaaS gives you a standard product configured through settings; custom software is engineered around your exact workflow, data model, and integrations. SaaS wins on speed and cost when a standard process fits. Custom software wins when the business logic is non-trivial, the system needs deep integration or compliance, or the software itself is a competitive advantage.
Cost scales with scope, integration surface, and compliance load rather than a fixed price tag. A focused first release is usually a fixed-scope engagement of a few months; larger platforms run as ongoing senior-squad delivery. We scope the smallest version that proves value first, so spend tracks delivered software instead of a year-long upfront commitment.
A production-grade first release usually ships in 8 to 16 weeks with a senior squad running discovery, architecture, and build on one cadence. Timeline is driven by integration and compliance complexity more than feature count, so we stage delivery to get a usable system into production early and harden it from there.
We build TypeScript end to end (Next.js, React, Node) with Go where it fits, Postgres for data, and cloud-native infrastructure on AWS or GCP with CI/CD and observability wired in from day one. The stack is chosen for type safety, operability, and long-term maintainability rather than novelty.
We build custom software across regulated and operationally complex industries — fintech, healthcare, logistics and supply chain, insurance, retail, and legal-tech. What connects them is non-trivial business logic, deep integration with systems you already run, and a compliance load a packaged product can't absorb. The deeper the domain, the more building to spec tends to pay off.
Yes. Custom software is a living system, so we stay on after launch — monitoring, hardening, and extending the product with the same senior engineers who built it. Many engagements continue as ongoing delivery once the first release is in production.
