A prototype demos. A product ships revenue.
We don't hand you slides or a throwaway proof-of-concept. We build multi-tenant SaaS with auth, billing, and cloud infra wired in — deployed to production and owned by you in full.
Built to perform
The fundamentals we get right on every build, so what we ship keeps working long after launch.
MVP in weeks
We ship a real, revenue-ready product fast, so you can put it in front of users and learn instead of guessing.
Built to scale
Multi-tenant architecture, clean data models, and infra that grow with you, so you add customers without rebuilding.
Secure by default
Auth, RBAC, encryption, and audit logs baked in from day one, with a clear path to SOC 2.
Revenue wired in
Stripe subscriptions, trials, usage billing, and dunning set up early, so you can charge from launch day.
Built for teams that need a real product, not a prototype
Whether you're shipping a first MVP or scaling past your first 1,000 customers, you get a senior team that owns the build end to end.
Founders with an MVP to ship
Turn an idea into a deployed, revenue-ready product in weeks instead of chasing quotes for months.
Funded startups scaling up
Add customers and enterprise features on architecture built to survive your Series A, not a rewrite.
Non-technical founders
Get a senior engineering team that owns the build end to end, so you don't need a CTO on day one.
Teams outgrowing spreadsheets
Replace brittle internal tools and manual workflows with a real multi-tenant app your customers log in to.
End-to-end, done for you
MVP development
We turn your idea into a working, launchable product, focused on the one core workflow that proves value in a single session.
Product architecture
Data models, tenant isolation with Postgres row-level security, and service boundaries designed to hold up well past your first 1,000 customers.
Auth, RBAC & billing
Sign-in with SSO and MFA, roles and permissions with real scopes, and Stripe subscription billing, wired together and production-ready.
Dashboards & analytics
Admin panels, customer dashboards, and usage analytics, so both your team and your users can see what matters and act on it.
Integrations & APIs
Type-safe REST and tRPC APIs, webhooks, and third-party integrations that connect your product to the tools your customers already use.
Cloud, CI/CD & scaling
GitHub Actions pipelines, Terraform infra on AWS or Vercel, and Sentry monitoring, tuned for uptime as you grow.
A product your customers log in to — and pay for
From the admin dashboard to the billing portal, every screen is production-grade — responsive on desktop and mobile, in your brand.
Dashboards that drive action
Real-time usage, revenue, and admin tooling your team and customers can act on at a glance.
Self-serve billing
A Stripe-powered portal where customers upgrade, add seats, and manage invoices without emailing you.
Fast on every device
Cached, tuned, and responsive, so the app stays quick as tenants and data pile up.
Built on the tools your stack already trusts
We wire your SaaS into the billing, auth, infra, and analytics platforms teams actually run in production.
What's included
Everything you need to launch and run a real SaaS, not a prototype you'll throw away in three months.
A clear path from idea to live
No black boxes. You always know what's shipping, when, and why.
Validate & scope
We pressure-test the idea, talk through your ICP, and cut the plan down to the MVP that proves value, at a fixed price you approve first.
- Pressure-test the idea
- Define your ICP
- Fixed-price MVP scope
Architect & design
We map the data model, multi-tenancy, and user flows, then design the UI in Figma before a line of code is written.
- Data model & tenancy
- User flows mapped
- Figma UI design
Build the MVP
Senior engineers ship the core product — auth, workflows, and billing — in focused weekly sprints with demos you can see.
- Auth & core workflows
- Stripe billing
- Weekly demo sprints
Launch
We deploy to production with CI/CD, monitoring, and error tracking, then put it in front of your first real users.
- CI/CD deploy
- Monitoring & alerts
- First real users
Scale
We harden security, tune performance, add features, and move you toward SOC 2 as demand grows.
- Security hardening
- Performance tuning
- SOC 2 readiness
What you can count on
From idea to a working MVP
TypeScript, front to back
Monitoring and uptime alerts
Integrations and APIs wired in
The SaaS foundations most builds get wrong
Anyone can ship a login form. We build the parts that decide whether your product survives its first enterprise deal and its 10,000th user.
Multi-tenancy
Tenant isolation with Postgres row-level security, so one customer's data can never leak into another's.
Auth & RBAC
SSO, MFA, and role-based permissions with real scopes and claims, not a single is_admin flag.
Subscription billing
Stripe plans, trials, proration, usage metering, Stripe Tax, and failed-payment recovery via dunning.
Security & SOC 2
Environment separation, encryption, and immutable audit logs that make a Vanta or Drata audit a checklist, not a rewrite.
Dashboards & analytics
Real-time usage, admin tooling, and metrics your team and customers can actually act on.
Performance & scale
Caching, background queues, and query tuning, so the app stays fast as tenants and data pile up.
How we compare to the alternatives
There are faster ways to write code and cheaper ways to buy hours. Here's how they hold up when your SaaS has to bill customers and pass a security review.
| What matters | DIY / boilerplate | Freelancer | Typical dev shop | seotools.pro |
|---|---|---|---|---|
| Time to a working MVP | Weeks of setup you glue together yourself | Slips as scope creeps | One to two quarters and a big invoice | A working, deployed MVP in 2-6 weeks. |
| Multi-tenancy | Copy-pasted org_id filters | Single-tenant, bolted on later | Billed as a change request | Postgres row-level security and tenant isolation from schema one. |
| Billing | Stripe Checkout, no dunning | The happy path only | Basic plans; you own the edge cases | Stripe subscriptions, proration, usage metering, tax, and dunning. |
| Security & SOC 2 | Entirely your problem | Rarely considered | A separate, later engagement | Encryption, audit logs, and RBAC wired for a Vanta or Drata audit. |
| Code & IP ownership | Yours, minus the license terms | Depends on the contract | Sometimes locked to their platform | 100% yours — your repos, your cloud, no lock-in. |
| After launch | You maintain all of it | Hard to reach again | A new SOW for every change | One senior team that scales, hardens, and ships with you. |
