Product and platform engineering for software other teams depend on.
SaaS lives or dies on shipping fast without painting yourself into a corner, staying up when customers are counting on you, and clearing the security bar that unlocks bigger deals. We can build and run the products and platforms that carry that weight, from first release to real scale.
The tensions every SaaS team has to hold.
Move fast, but don't accrue debt that crushes you. Ship features, but never drop the SLA. Sell upmarket, but pass their security review first. These pulls are the real work, and they shape every architectural call.
Ship fast without boxing yourself in
Early speed is survival, but the shortcuts that get you to launch can become the wall you hit at scale. The craft is architecture that's quick to build on now and doesn't have to be torn out later.
Your customers' uptime is your reputation
When other businesses run on your product, an outage is their outage. Multi-tenancy, observability, and a real reliability story aren't maturity milestones, they're what the SLA you signed actually requires.
Security is the gate to bigger deals
Moving upmarket means a buyer's security team reviews you. SOC 2, SSO, and sound controls stop being “later” the moment an enterprise logo is on the line, they're a prerequisite to the contract.
Billing is where money quietly leaks
Usage metering, subscriptions, proration, and dunning are deceptively hard, and every edge case you miss is revenue lost or a customer overcharged. The money plumbing has to be exact.
Velocity, without drowning in debt
The pressure to ship never stops, and unmanaged tech debt slowly turns every change into a slog. Staying fast for years takes a platform underneath the product that's deliberately kept healthy.
From first commit to the platform underneath.
Whether you're starting a product or scaling one, we build, and can run, the engineering behind it.
0-to-1 product engineering
From prototype to a production-grade first release, fast, but on a foundation that won't have to be thrown away.
Multi-tenant SaaS architecture
Tenant isolation, data partitioning, and scaling patterns that hold up as you go from ten customers to ten thousand.
Platform & infrastructure scaling
Re-architecting and hardening the systems under a growing product so performance and cost scale sensibly together.
API platforms & developer experience
Well-designed APIs, SDKs, and docs that turn your product into something other teams build on with confidence.
Billing, metering & subscriptions
Usage metering and subscription logic that's accurate to the edge case, so revenue is captured and customers are billed right.
Reliability, observability & on-call
Monitoring, SLOs, and incident practice, and a team that can carry the pager, so the SLA is something you can actually keep.
Built to clear the security review.
When you sell to other businesses, their procurement and security teams set the bar. We build to the controls and practices that get you through the questionnaire, and produce the evidence to back them.
Review our approach with your team →We engineer the systems we build to meet these standards’ controls and produce the supporting evidence; Paragon does not claim to hold these certifications itself.
Fast to ship, built to scale.
Get clear on the product and the trajectory
We learn the product, the users, and where it's headed, the scale targets, the deals on the horizon, the constraints, so the architecture serves where you're going, not just where you are.
Design for change, not just the demo
We choose proven, deliberate foundations, multi-tenancy, data model, and security, that let you move fast now without an expensive rewrite later.
Release continuously, with the safety nets
CI/CD, automated testing, and observability are in from the start, so you ship often, catch regressions early, and have the controls a security review will ask for.
Keep it reliable as the load grows
SLOs, monitoring, and an incident process keep the SLA intact, while we manage tech debt deliberately so velocity holds up as the product and customer base grow.
What we bring to your product build.
Senior engineers who build software products for a living, a discovery-led start, and the disciplines SaaS runs on, multi-tenancy, reliability, security, and clean APIs, brought to your product from the first sprint.
This is the work we do every day
Multi-tenant products, scaling platforms, security for procurement, and reliable operations are our core craft. We bring that engineering straight to your product.
We embed with your team
We pair and review alongside your engineers, acting as a force multiplier rather than a black box, your team levels up as we ship together.
Built to pass the security review, evidenced
We build to SOC 2 and enterprise security expectations and produce the documentation that gets you through a buyer's review, controls you can verify.
You own all of it
Code in your repositories, infrastructure in your accounts, standards-based throughout. No proprietary runtime and no lock-in, your product stays yours.
What product teams ask us first.
Can you embed with our existing engineering team?
Yes, we work alongside in-house engineers regularly, pairing and reviewing so your team levels up as we build, rather than handing over a black box.
Do you build from scratch, or scale an existing product?
Both. We take products from prototype to a production-grade first release, and we re-architect and harden existing platforms that are straining under growth.
Can you help us get through a SOC 2 or security review?
Yes, we build to SOC 2 and enterprise security expectations as part of the work and produce the documentation and controls a buyer's security team will ask to see.
How do you handle multi-tenancy and reliability?
Isolation and scaling patterns are designed in, with observability, SLOs, and an incident process so the SLA you commit to is one you can actually keep.
Do we own the code and the infrastructure?
Always. Everything is built in your repositories and your cloud accounts, no proprietary runtime, no lock-in.
Building or scaling a product? Let's talk.
Tell us where the product is and where it's headed. We'll bring senior engineers, a clear plan, and a team that can ship fast and stay on the pager.
