SaaS Consulting
From idea to paying customers.
Building a SaaS is more than writing code. It's auth, billing, multi-tenancy, onboarding, integrations, and infrastructure that doesn't fall over at 50 customers. We've shipped multiple SaaS products end to end — we help founders skip the expensive lessons.
The problem
Most SaaS startups die between MVP and product-market fit.
The first version ships. A few customers sign up. Then reality hits: billing edge cases, onboarding friction, churn you can't explain, a database that wasn't designed for multi-tenancy, an API that nobody documented, and infrastructure costs climbing faster than revenue. Founders end up rebuilding what they already shipped instead of moving forward.
"The hard part of SaaS isn't the demo. It's customer #10 through #1,000."
We help founders make the architectural and product decisions early that pay off later — and rescue the ones who already made the wrong ones.
What we cover
Every layer of your SaaS
Architecture & Multi-tenancy
Schema design, tenant isolation, role-based access. Built once, painful to fix later — we get it right the first time.
Auth & Billing
Stripe, subscriptions, usage metering, trials, dunning, tax. Auth flows that scale from solo signups to enterprise SSO.
Onboarding & Activation
The make-or-break first 10 minutes. Empty states, sample data, checklists, in-product nudges — every detail engineered for activation.
Integrations & API
Webhooks, OAuth, public API design, rate limiting, SDKs. Make your SaaS the system other tools want to plug into.
Pricing & Packaging
Tiering, seat vs. usage, enterprise plans, paywalls. The unsexy stuff that actually decides whether you have a business.
Cloud Infrastructure
Serverless-first, observability, CI/CD, security. Infrastructure that scales gracefully and doesn't wake you up at 3 AM.
Who it's for
SaaS founders who want fewer surprises
How we engage
Three ways to work together
SaaS MVP Build
8-12 week focused engagement. From idea to a production SaaS with auth, billing, and the integrations your users expect.
Fractional SaaS CTO
Embedded part-time. We make the architecture calls, set the bar with your team, and unblock decisions before they become rewrites.
SaaS Audit
One-week deep dive into your codebase, infra, billing, and onboarding. You leave with a prioritized list of what to fix and what to ignore.

FAQ
SaaS questions founders ask
How long does a SaaS MVP take? +
Most ship in 8-12 weeks. The variance comes from integrations and compliance — a simple B2C SaaS lands around 8, a regulated B2B SaaS with SSO and audit logging closer to 12. We scope it on the first call.
Should we use Stripe or build our own billing? +
Use Stripe. Build subscription logic, usage metering, and entitlements on top of it. The only teams that should build their own billing have a real reason — most who try end up rebuilding badly what Stripe gives you for free.
What stack should we use? +
Depends on your team and your domain. We are technology-agnostic. For most SaaS we lean toward TypeScript on the front-end with a managed Postgres backend, but the right answer is whatever your team can maintain and ship.
How do we handle multi-tenancy? +
Shared schema with tenant IDs for most cases — simpler, cheaper, easier to migrate. Schema-per-tenant only when compliance or noisy-neighbor concerns force it. We get this decision right early because changing it later is a nightmare.
Can you help with pricing and packaging? +
Yes. We help you structure tiers, decide between seat vs. usage pricing, design enterprise plans, and build the paywall logic. Pricing is product — we treat it that way.
Do you accept equity? +
Yes — cash, equity, or a mix. If we believe in your product and the founder, we are open to sharing in the upside. Let's talk about what fits your stage.
