From concept to production — senior-led, full-stack.
SaaS & Custom Software Development
Building software that actually ships — on time, on budget, and built to scale — requires more than good intentions. It requires senior engineers who've seen what breaks, architects who plan for scale from day one, and a delivery process that keeps you informed at every step.
Continuum Intelligence builds SaaS platforms, web applications, internal tools, APIs, and mobile products for founders and enterprises. We handle the full stack — frontend, backend, database, infrastructure, and DevOps — as one team accountable for the whole product, not a collection of specialists who hand off to each other.
We are headquartered in Spokane, Washington and serve clients across the Pacific Northwest, the US, and globally. Our engineers are senior. Our process is transparent. And we don't disappear after launch.
What we deliver
Every engagement is scoped to your specific needs — not a fixed template. Here is what falls within this service pillar.
Frontend Development
React, Next.js, and TypeScript applications. Fast, accessible, and built for real user behavior — not just pixel-perfect mockups.
Backend & API Development
Node.js, Python, and Go backends. REST and GraphQL APIs designed for performance and long-term maintainability.
Database Architecture
PostgreSQL, MongoDB, Redis, and hybrid data architectures. Schema design, query optimization, and migration planning.
Cloud Infrastructure
AWS, GCP, and Vercel deployments. Infrastructure as code, auto-scaling, and cost optimization built in from the start.
DevOps & CI/CD
Automated pipelines, containerization with Docker, and Kubernetes orchestration for teams that ship frequently.
Mobile Development
React Native applications for iOS and Android. Shared codebase, native performance, and deep integration with your web product.
How an engagement runs
Every engagement follows a clear structure so you know what to expect and when — no surprises, no disappearing acts.
Discovery & Architecture
We map your requirements, define the tech stack, and produce a technical specification before any code is written.
Sprint-Based Development
Two-week sprints with weekly demos. You see real progress every week — no black boxes, no surprises.
QA & Launch
Automated testing, manual QA, and staged deployment to catch issues before they reach production.
Post-Launch Support
Monitoring, bug fixes, and performance optimization after launch. We don't disappear when the deploy button gets pressed.
Frequently asked questions
How much does custom software development cost?
Scope drives cost more than technology. A focused MVP typically ranges from $25,000–$75,000. Full-featured SaaS platforms run $75,000–$300,000+. We give you a fixed-price estimate after a discovery session, not before.
How long does it take to build a SaaS product?
A production-ready MVP typically takes 8–16 weeks depending on complexity. We scope conservatively and deliver on schedule. Rushing scope into an unrealistic timeline is the most common reason software projects fail.
Do you work with existing codebases?
Yes. We take on legacy code, audits, rewrites, and extensions of existing systems. We assess technical debt honestly before quoting so there are no surprises mid-engagement.
What happens after the project launches?
We offer ongoing support, maintenance retainers, and continued development engagements. Most clients continue working with us post-launch as their product evolves.
