What you get in 8–10 weeks (MVP plan)

We tailor scope to your stage and runway. A typical SaaS MVP build combines brand essentials, core UX, and a production‑ready web app with analytics and payments.

• Week 0–1: MVP brief and architecture

• Product thesis, target user, core use cases, success metrics

• Technical discovery (auth, data model, integrations, compliance constraints)

• Architecture draft (Next.js app router or Webflow + backend services; hosting plan)

• Week 2–3: UX flows and data model

• End‑to‑end user journeys, wireframes, and acceptance criteria

• Schema design for core entities; API/interface contracts; tracking plan

• Week 4–5: UI system and brand essentials

• Tokenized design system (type, color, spacing, components)

• Logo/wordmark refinement if needed; marketing copy for launch page

• Week 6–7: Build and integrate

• Front‑end implementation, auth, billing, emails, analytics

• Integrations (Stripe, third‑party APIs, CMS as needed); QA plan

• Week 8: Hardening and launch

• Test coverage on critical paths, performance pass, accessibility checks

• Runbook, observability dashboards, incident/rollback procedure

• Optional Weeks 9–10: Growth layer

• Pricing and plan logic, onboarding experiments, CRM + marketing automations

Deliverables: clickable prototype, production repo, design system, content/copy, analytics + events spec, test plan, launch checklist, and a post‑launch iteration backlog. Capabilities

Decision guide: Webflow vs. Next.js for your SaaS

Use this to choose the fastest path that still scales.

• Webflow path: Enterprise‑grade marketing site with CMS, animations, and SEO. We are a certified Webflow partner. Webflow at Zypsy | Webflow Premium Partner profile

• Next.js path: Production SaaS app with modern DX (TypeScript, server components), edge caching, and integration surface for billing, auth, and data.

Recommended SaaS architecture (opinionated defaults)

• Front‑end: Next.js (App Router), TypeScript, component library mapped to the design tokens delivered in Figma

• Auth: OAuth/email magic links with enterprise SSO optional; session + token strategy documented in the runbook

• Data: Managed Postgres; Prisma or equivalent ORM; migration discipline and seed scripts

• Payments: Stripe subscriptions with metering hooks; pricing experiments gated by feature flags

• Content: Headless CMS for docs and marketing (editor‑friendly); MDX for developer surfaces

• Observability: Error tracking, logging, and APM with alerting policies; product analytics with an events spec aligned to activation KPIs

• Delivery: CI/CD with preview environments; infra as code for reproducibility; per‑env secrets strategy

Note: Stack choices vary by domain, compliance, and existing constraints; we finalize them in technical discovery. Capabilities
