SaaS development

SaaS built to operate after launch.

CrecyStudio builds multi-tenant products with the commercial and operational layer included: authentication, billing, permissions, onboarding, notifications, admin tooling, analytics, and support workflows. Korent and Fleiko are live examples of that product discipline.

Para quién

Best for founders and teams ready to turn a validated product idea into operating software.

  • +

    You have a validated SaaS idea and need senior product and engineering ownership through launch.

  • +

    You've tried no-code, hit the ceiling, and need a real product foundation that scales past 50 users.

  • +

    You have an existing SaaS that's stalled, breaking, or unmaintainable, and you need someone to take it over.

  • +

    You want product decisions, architecture, billing, onboarding, and post-launch operations considered together.

Ideal para

Best when the goal is a SaaS product that can be operated, sold, and extended after launch.

  • You have a real audience or first ten customers in mind — not a 'build it and they'll come' bet.
  • You want a delivery partner that can stay involved after launch as the product and infrastructure evolve.
  • You're OK paying for a Discovery Sprint to scope the real work before committing to a build.

No es el primer paso

Probably not the right first move if…

  • -

    You mainly need a marketing website or e-commerce store — start with our /websites or /ecommerce lane.

  • -

    You want the cheapest possible MVP and don't care if it survives past ten users.

  • -

    You don't have a clear use case or audience yet — start with our automation audit or a strategy call before committing to a build.

  • -

    The engagement is equity-only; CrecyStudio works on paid project or retainer engagements.

Problemas que resolvemos

Where SaaS builds become expensive to fix later.

01

Multi-tenancy, billing, or permissions were deferred until the product already had customers.

02

The first version works at low volume but the data model and queries do not support real usage growth.

03

Trials, billing states, role-based access, lifecycle messaging, and admin tooling were treated as afterthoughts.

04

The product launched without documentation, observability, or a clear path for ongoing ownership.

Lo que recibes

What we build into your SaaS — from day one, not as an afterthought.

Multi-tenant from day one

  • Tenant isolation at the database layer with Row Level Security — not just app-level checks that leak when a query is rewritten
  • One codebase, many customers — without the painful rewrite at customer #50
  • Architecture patterns proven in Korent and Fleiko

Billing, auth, and identity built in

  • Stripe-powered subscriptions, trial logic, plan upgrades, and dunning flows that actually retain — not a bolt-on after launch
  • Auth with role-based access control, team invites, and admin tooling from the first sprint
  • The commercial and identity layer designed before it becomes a migration project

Retention loops, not just features

  • Onboarding flows, lifecycle email, and in-product nudges designed before the build, not patched in after churn shows up
  • Activation metric defined up front, instrumented from week one
  • Lifecycle and activation flows designed around the product's actual conversion path

Production-safe AI where it earns its keep

  • Confidence-gated AI when it solves a defined product or operational job
  • Guardrails, human review, and audit trails where AI has meaningful operational impact
  • If AI is central to the product, the AI Integration service covers the deeper production requirements

Product experience

Live SaaS experience behind the work.

Korent and Fleiko demonstrate the same product concerns client SaaS work requires: multi-tenancy, billing, permissions, onboarding, operations, and post-launch ownership.

Korent

Multi-tenant rental operations SaaS with public storefronts, checkout, subscriptions, Stripe Connect, e-signatures, delivery workflows, website management, and an operator copilot.

Fleiko

Fleet and dispatch SaaS with role-aware portals, subscriptions, GPS, driver workflows, proof of delivery, mobile surfaces, and AI assistance.

Couranr

A delivery operations platform with customer and business workflows, payments, dispatch, tracking, proof, and operational control.

Couranr Market

A local e-commerce platform combining storefront, checkout, delivery windows, order operations, inventory and returns, with AI shopping assistance.

Proceso

From product definition to paying customer.

Every track starts the same way: we scope the real work first, validate before committing to a full build, and ship with the boring-but-essential SaaS plumbing in place from day one.

01 — WEEK 1–2

Discovery Sprint

We scope your SaaS: architecture, billing model, multi-tenancy, core flows, and sequencing. You walk away with a fixed-price proposal for the full build.

02 — WEEKS 2–4

Foundation

Auth, billing, multi-tenancy, and core schema in place. The boring-but-essential SaaS layer that lets everything else move fast — without rebuilds at month 6.

03 — WEEKS 4–10

Core build

The flow that earns money — built, tested, and integrated with Stripe, auth, transactional email, and admin tooling. Real users in staging by week 8.

04 — LAUNCH

Go live

Production deploy with payments, billing, lifecycle messaging, monitoring, and launch verification in place.

05 — OPERATE

Build & Operate (optional)

Monthly retainer to keep shipping features, monitoring infrastructure, and tuning retention loops while you focus on growth. Not a leash — opt in or out anytime.

Precios

Priced around product scope, launch risk, and operating complexity.

Every track starts with a Discovery Sprint: a fixed-price definition of product scope, architecture, delivery sequence, and budget. You receive the written plan whether or not you continue into the larger build.

DISCOVERY SPRINT

Starting at $4,000

1–2 weeks, fixed-price. Architecture, multi-tenancy model, billing plan, sequencing, and a fixed-price proposal for the full build.

Starting point

MVP SPRINT

Starting at $25,000

8–12 weeks, fixed-price. From scoped plan to live SaaS with paying customers — multi-tenancy, Stripe billing, auth, and the core flow that earns money. Most builds land between $25k and $45k.

Most common

BUILD & OPERATE

Starting at $6,000 / mo

Ongoing product delivery, infrastructure monitoring, and support sized to your roadmap and release cadence.

Post-launch or long-arc builds

SAAS RESCUE

Starting at $5,000 audit

Fixed audit (5–10 working days) of a stalled or breaking SaaS — written remediation plan, prioritized. Stabilization engagement (T&M or retainer) follows based on what the audit finds.

For existing SaaS

FAQ

SaaS build FAQ

How is this different from your Custom Web Apps service?

Custom Web Apps is for internal tools, portals, and bespoke client apps — software you build for a specific business to use. SaaS Development is for product businesses — software you sell as a subscription to many customers, with multi-tenancy, billing, retention, and support designed in from day one. If your buyer is your customer (not your team), you want this service.

Do you take equity?

CrecyStudio works on paid project and retainer engagements rather than equity-only arrangements. If you need a technical co-founder instead of a delivery partner, that is a different engagement model.

What if I already have a half-built SaaS that's broken or stalled?

That's exactly what SaaS Rescue is for. We start with a fixed-fee audit (5–10 working days), give you a written remediation plan, and you decide whether to engage us for the rebuild or take the plan elsewhere. No retainer commitment from the audit.

Can you keep operating it after launch?

Yes — Build & Operate is the retainer track. We keep shipping features, monitoring infrastructure, tuning retention loops, and being on-call. Sized to your real velocity, not a fixed contractor headcount.

What SaaS experience does CrecyStudio bring?

Korent and Fleiko are live multi-role products with billing, permissions, onboarding, operational dashboards, and post-launch workflows. That experience informs how CrecyStudio scopes architecture, commercial logic, support surfaces, and long-term ownership from the start.

Do you publish prices because you're cheap?

We publish 'starting at' bands so you can self-qualify instead of burning 90 minutes on a discovery call to learn we're out of budget. Final pricing comes from the Discovery Sprint — which is fixed-price too, and yours to keep whether you continue with us or not.

What tech stack do you build on?

Default: Next.js (React) on the frontend, Supabase (Postgres + Auth + Storage with Row Level Security) for the backend, Stripe for billing, Resend for transactional email, Vercel for hosting. We pick this stack because it gets you to multi-tenant and production-safe AI fast, with no surprise licensing costs. We'll swap parts if your build genuinely needs it.
