Case Study — Fintech SaaS

A PLG fintech with 17,600+ users and no activation data. We built the diagnostic they needed to grow.

Freemium stock research platform, S&P Global data partnership, 46 product releases in 11 months — and no documented conversion rate, activation metric, or cohort. We ran the full Product DNA audit.

Before.

A consumer fintech SaaS had built real traction — 17,600+ users on a freemium stock research platform, a genuine S&P Global data partnership that gave them institutional-grade market intelligence at consumer prices, and a product shipping a major release every 7 days on average. The PLG mechanics were in place: public pricing, self-serve billing, no-credit-card free tier across 153 exchanges.

But the growth machine had no instrumentation. No documented activation rate. No free-to-paid conversion rate. No cohort retention data. No churn signal. A 62-event tracking spec had been designed and handed off. Implementation status: unknown. They were operating a pure PLG product entirely on assumptions.

Alongside the data gap, the product had evolved fast: a new 3-tier pricing structure, two major feature launches (Portfolio Statistics in January, Stock Alerts in March), and a positioning shift. The tier differentiation was built on usage caps — 10 AI queries vs 50 vs 500, alert counts, analyst estimate depth — not on feature class. No one had assessed whether that architecture was creating upgrade pressure or neutralising it.

The Situation
  • Zero documented conversion rate, activation metric, or retention cohort on a pure PLG product
  • No way to identify which activation event predicted 30-day retention
  • Tier differentiation built on usage caps, not feature class — weak upgrade pressure
  • 9 features assumed in the product that had not actually been built or were on the roadmap only
  • 13 direct competitors, no systematic map of where the product won, lost, or was vulnerable

What we did.

A complete Product DNA audit across all 10 strategic dimensions, competitive intelligence mapping, a feature audit against actual product state, and an analytics implementation plan.

Step 1 — Product DNA Classification
Full 10-dimension strategic classification: pricing architecture, user topology, growth motion, value delivery model, buyer/user map, activation pattern, retention and moat type, complexity/time-to-value, revenue expansion model, and competitive positioning. Each dimension scored and evidence-grounded against the actual product — not benchmarks or opinions.
Step 2 — Feature Audit Against Actual Product State
Audited 19 product surfaces and validated the feature set against the actual product (not the roadmap or marketing copy). Identified 9 features previously assumed in the analysis that were either in development, planned-only, or broker-integration-dependent: Tax-Loss Harvesting, API Access, PDF Reports, White-Label, Client Portfolios, Bulk Import, AI Portfolio Review (in dev), and others. All removed from the active recommendations.
Step 3 — Cross-Dimension Conflict Detection
Four active cross-dimension conflicts identified: (1) Thin tier differentiation — usage caps only, no feature-class gates, undercuts PLG upgrade pressure. (2) Intelligence Layer value model with a weak data moat — S&P data is licensed, not proprietary. (3) Instant-value activation without deep retention mechanisms. (4) Generous free tier creating structural weak conversion pressure. Each conflict mapped to specific business impact and revenue delta.
Step 4 — Competitive Intelligence
13 direct competitors mapped across pricing, feature coverage, data sources, and positioning. Identified where the product won — AI integration depth, UX quality, release velocity (v2.47 in 11 months), community responsiveness — and where it was exposed: data exclusivity (S&P is available to competitors), community moat, and broker integration depth vs established players.
Step 5 — Analytics Implementation Plan
62-event tracking plan designed for a PLG conversion funnel: Signup → Dashboard Load → First Stock Searched → First Watchlist Add → AI Chat Used → Premium Conversion → Tier Upgrade. Each event tied to a specific business decision. Implemented as P0/P1/P2 priority with rationale for each.
Step 6 — Activation Strategy & Revenue Model
Six activation event candidates identified — each a hypothesis for the aha moment (first stock search, first AI chat, first watchlist add, first Top Investors view, first screener result, first alert trigger). Retention cohort methodology designed to validate each. Revenue model: strengthening tier differentiation from 10% to 25% upgrade rate adds approximately $210K annually per 10,000 paying users.

A note on outcomes. This engagement delivered strategic diagnostic work and implementation frameworks — not end-state metrics. The value is in what the team can now do: implement instrumented analytics with a clear spec, test activation hypotheses with a validated methodology, and make pricing decisions with a clear picture of the architectural conflicts. Outcome metrics will follow from implementation.

What you can do now.

Know what your PLG funnel is actually doing

A 62-event tracking spec tells your engineering team exactly what to instrument. Once it’s live, you know your activation rate, free-to-paid conversion rate, and which feature usage predicts retention — for the first time.

Find the aha moment and build toward it

Six activation event candidates are defined. The retention cohort methodology is ready. Implement analytics, run the analysis, and you know which onboarding moment to optimise around — not based on instinct, but on measured retention correlation.

Make pricing decisions from architecture, not instinct

The tier differentiation conflict is documented with specific revenue impact. The recommendation to shift from usage-cap gates to feature-class gates has a model behind it. The next pricing iteration starts from evidence — including a $210K annual upside estimate per 10K users.

PLG products require a different kind of diagnostic — you’re not looking at a single conversion path but at the structural alignment between pricing, activation, retention, and moat. This engagement required finding the conflicts the team couldn’t see because they were inside the product.
