What we build

Six SaaS shapes, one multi-tenant foundation

Whatever flavour your SaaS takes, the spine is the same — proper tenancy, billing, RBAC, observability — built right the first time.

B2B SaaS platforms

Multi-tenant from day one — workspaces, RBAC, audit logs, SSO, seat-based billing. The plumbing your enterprise customers will ask about.

Vertical SaaS

Industry-deep products — healthcare, legal, real estate, manufacturing. Compliance, certifications, and integrations specific to that industry.

Internal SaaS / ops

Tools your operations team uses every day — admin panels, ops consoles, internal billing portals — built to enterprise quality, not Sheets.

Marketplace SaaS

Two-sided platforms — sellers, buyers, escrow, ratings, payouts. Stripe Connect, deferred KYC, dispute workflows, the works.

EdTech SaaS

Course platforms, exam engines, school-management systems. Per-school tenancy, student/teacher/admin role separation, content delivery at scale.

Productivity SaaS

Project management, CRMs, knowledge bases, AI-assisted writing tools. Real-time collab via WebSockets, deep search, mobile companion apps.

How we ship

From kickoff to your first paying tenant

Every phase has a written deliverable, a fixed timeline, and a sign-off gate. No surprises.

  1. 01

    Tenancy & data model

    Discovery

    Multi-tenant decisions made upfront — shared schema with row-level security, schema-per-tenant, or DB-per-tenant. Wrong call here is expensive to undo later.

    • Tenant isolation strategy (RLS / schema / DB)
    • RBAC matrix written down
    • Audit-log requirements & retention
    • Compliance flags (SOC2, GDPR, HIPAA)
  2. 02

    Billing & plans

    Pricing

    Plan structure, seat-based vs metered, free trials, annual discounts, tax handling. Stripe Billing wired to your tenant model — not bolted on at launch.

    • Plan catalog & pricing rules
    • Seat/usage metering pipelines
    • Stripe Tax + invoices
    • Trial → paid conversion flow
  3. 03

    Auth, RBAC & SSO

    Identity

    Email/social login, optional SSO via SAML / OIDC, scoped roles, invitations, magic links. Built once, works for every customer that ever signs up.

    • Email / social / magic link
    • SSO via SAML / OIDC
    • Org → workspace → user roles
    • Invitation + onboarding flows
  4. 04

    Product build

    Build phase

    Sprint-based feature build — every two weeks you see a working build on staging. APIs documented as we go, contract-tested with the frontend.

    • Sprint demos every 2 weeks
    • OpenAPI / GraphQL schema
    • Feature flags for safe ships
    • Test coverage gate (≥70%)
  5. 05

    Infra, scale & observability

    Pre-launch

    Production environment built with Terraform, deployed via CI, monitored from day one. Backups, runbooks, paging — set up before anyone signs up.

    • Terraform-managed infra
    • Auto-scaling + read replicas
    • Sentry + Datadog + log retention
    • Runbooks & on-call rotation
  6. 06

    Launch & growth ops

    Launch + ongoing

    Onboarding, in-product analytics, churn alerts, customer-success tooling. We stay on for feature work, scaling, security patches, SOC2 prep.

    • Product analytics + funnels
    • Churn / health-score alerts
    • SOC2 / security retainer
    • Roadmap-driven feature work
Featured project

From 6 spreadsheets to 38 tenants. Real numbers.

Apex Distributors HQ

The challenge

Six warehouse spreadsheets, no real-time stock visibility, zero audit trail. Sales reps double-booking inventory. Distributors blocked from self-serve ordering.

What we shipped

Multi-tenant SaaS with org / warehouse / user roles, real-time inventory, RBAC, Stripe-billed sub-accounts. Onboarded 38 distributor tenants in 6 months. SOC2 Type 1 in 8.

The code we ship

Tenant isolation at the database level

Postgres row-level security + tRPC tenant procedure means a developer can't accidentally query across tenants — the database refuses.

server/routers/invoice.tstRPC · Postgres RLS
 1// 1. Tenants are isolated at the database level via RLS. 2CREATE POLICY tenant_isolation ON invoices 3  USING (tenant_id = current_setting('app.tenant_id')::uuid); 4 5// 2. tRPC mutation — RBAC + tenant scoping in one place. 6export const invoiceRouterrouter({ 7  create: tenantProcedure 8    .use(requireRole("admin")) 9    .input(z.object({ amount: z.number().positive() }))10    .mutation(({ ctx, input }) => db.invoice.create({11      data: { ...input, tenantId: ctx.tenantId }12    })),13});

Common questions

Things people ask before they sign

  • Default: shared schema with row-level security on Postgres — cheaper, faster to ship, isolation strong enough for the vast majority of B2B SaaS. We move to schema-per-tenant or DB-per-tenant when compliance, data residency, or noisy-neighbor risk genuinely require it. We agree the call in writing in week 1.
