NodeScript

How Strategic Analysis Saved €240k per Year

The NodeScript visual workflow builder in action

NodeScript is UBIO's visual programming platform that powered 300M monthly automations and facilitated $500M in bookings for enterprise clients. After two years of successful internal use, we attempted to commercialise it as a standalone product. I led the investigation that uncovered 98% user churn, revealing a fundamental mismatch between internal success and market needs - ultimately saving €240k/year in misguided investment.

30 Second Story

Impact: Resources redirected to profitable products

01.

The Optimistic Beginning: "Let's fix the funnel!"

The Plan
I kicked off the year with classic optimisation thinking - improve the entire user funnel through research, rebrand, and systematic improvements.

User journey mapping: From landing to payment.

Initial Actions

  • Launched user interview program

  • Kicked off complete rebrand project

  • Mapped user journey from landing to payment

  • Built beautiful new design system

Early design work: from visual exploration to a style tile to early UI ideas.

The Surface Metrics

  • 231 total activated users

  • 1-11 new users activating daily

  • 2.6M+ invocations each 6 hours

  • 300M+ monthly automations for Google, Trivago, KIWI

  • Positive feedback from our handful of power users

Everything looked healthy. We were ready to optimise our way to growth.

The Grafana dashboard showed a steady stream of new signups.

The Uncomfortable Discovery: "Wait, let me check cohort analysis..."

The Moment
While planning funnel improvements, I remembered reading about cohort analysis. "Let me just check our retention..."

The cohort analyses in Google Analytics. Uhoh.

What I Found

  • 98.1% of users never returned after Week 1

  • 0% retention by Week 4 - every cohort dropped to zero

  • 231 activated users were actually just people trying it once

  • The brutal truth: Zero product-market fit hidden behind vanity metrics

The Realisation
Our "healthy" metrics were hiding a brutal truth - we had zero product retention.

The Pivot to Activation: "Maybe better onboarding will fix this?"

New Hypothesis: Users just need help getting started. If we show them the value faster, they'll stick around.

What I Did

  • Interviewed recent signups (including colleagues)

  • Ran activation workshop

  • Co-created pre-built templates for immediate use

  • Fine-tuned guided onboarding flows

The Uncomfortable Discovery

  • Colleagues learned NodeScript in just one day

  • The tutorials worked - it was already easy to learn

  • The real insight: If it's easy to learn but nobody's using it, the problem isn't usability

The Reality: "You can't optimise your way out of no product-market fit"

Post-Release Reality

  • Activation improvements shipped

  • Minimal impact on retention

  • Senior management growing impatient

  • Resources being questioned

The NodeScript Paradox

Easy to learn (1 day to proficiency)

Powerful capabilities (300M+ invocations monthly)

Beautiful interface

No external traction


We'd perfected a solution to a problem nobody had.

Strategic Decisions That Saved €240k/Year

  • Product development paused

  • Team redirected to revenue-generating products

  • Engineering resources reallocated to proven solutions

  • Company focus restored to core business

Reflections

The most dangerous metrics are the ones that look healthy. Our 231 activated users hid a 98% churn crisis. I started trying to optimise funnels and ended up discovering there was no funnel to optimise at all.

"The thinking process that Sjors delivered behind all of this adds the most value. Design is identifying the problems that everyone seems to be ignoring, and then think structurally about what can be done about them."
