Why Most MVPs Fail

Four predictable reasons — and how FI Digital engineers around each of them.

Product thinking before a line of code
Scope locked in Week 1 — no drift
Production stack — no low-code ceiling
Distribution designed into the product

Our SaaS & MVP Engagement Model

Wks 1–3

Discovery & Validation

"Before a single line of code."

A commercial interrogation of your idea. Who is the customer? What is the minimum feature set that makes switching worthwhile? We produce a Product Brief defining validated user personas, minimum viable feature set, pricing hypothesis, launch strategy, and technical architecture. We challenge your assumptions. We test your value proposition with real users.

Deliverable: Product Brief — scope, personas, architecture, launch plan

What a Production SaaS Platform Needs

Six capabilities every commercial SaaS product requires from Day 1 — not bolted on later.

Multi-Tenant Architecture

Every customer's data is fully isolated. Tenant-level access controls, data separation, and the ability to manage each customer's configuration independently.

Subscription & Billing

Stripe or Paddle integration for plan management, free trials, upgrade/downgrade flows, dunning, and payment failure handling.

Admin Dashboard

Usage metrics, customer management, support tools, and operational controls. Your team needs visibility into every customer's usage without touching the database.

Onboarding Flows

Guided first-use experience designed to reach the first value moment before the user loses interest. Activation is a product feature, not a marketing problem.

Usage Analytics

PostHog, Amplitude, or Mixpanel for feature adoption tracking, drop-off analysis, funnel optimisation, and cohort retention. Built in from Day 1.

Security & Compliance

SOC 2 Type II readiness, Privacy Act compliance, and penetration testing for products handling sensitive data. Not an afterthought — engineered in from the architecture stage.
