The Opportunity

Infrastructure ready. Consumers blocked by trust.

Open Banking in Australia was built on the promise of consumer control, transparency, and secure data sharing through the Consumer Data Right (CDR). In practice, that model introduced a behavioural challenge: users still had to overcome fear, effort, and uncertainty before connecting their bank accounts to a third-party service.

Consumer adoption was much lower than infrastructure readiness suggested. A 2024 strategic review noted that at the end of 2023, only 0.31% of bank customers had an active data-sharing arrangement — while industry commentary called for simpler consent experiences and clearer consumer propositions.

😰 Fear
😮‍💨 Effort
🤷 Uncertainty

The trust gap between what Open Banking could do and what consumers were willing to try was the single biggest obstacle to growth.

Competitive Landscape (2023)

Australia's automated subscription-tracking space was sparse. Most alternatives were manual-entry tools, full budgeting apps with secondary features, or global apps lacking local bank support — highlighting Waave's first-mover edge via CDR/Open Banking.

Ideal Customer Profile

ICP: 25–45yo urban pros wasting $670/yr on subs. Wendi = first-mover sub hunter.

Demographics

  • Australians aged 25–45, urban (Sydney/Melbourne)
  • Middle-income professionals/families ($60k–$120k)
  • Tech-comfortable, responsive to savings hooks

Pain Points

  • Overlooked subs — avg. AU household wastes $670/yr (NAB)
  • Bank juggling across multiple accounts
  • Cost-of-living squeeze driving savings urgency

Behaviours

  • 70% aware of subs but only 40% actively track them
  • Use budgeting apps, open to new fintech tools
  • Share savings tips socially — viral potential

Why Wendi Fits

Frictionless CDR flow delivers value in <2 minutes, building trust that leads to the payments upsell. Free, instant, and sub-focused — exactly what the ICP needs, exactly when cost-of-living pressure peaks.

The Insight

Value exchange > data rights talk

Waave recognised that trust in Open Banking would not be won through abstract messaging about data rights alone. The business needed a value exchange strong enough to justify consent, especially in a market where consumers were already overloaded by subscription costs and sceptical of sharing financial data.

The product insight: subscription tracking is an easy-to-understand pain point with immediate personal value. If users could quickly discover forgotten or duplicated subscriptions, Waave could turn a high-friction data-sharing decision into a practical money-saving action.

Free sub tracker = consent gateway to Pay by Bank.

The shift

"Share your data — it's your right"
"See what you're overpaying — free, in 60 seconds"

Flow Innovation

A 3-step flow that turned compliance into conversion

Waave's Wendi flow optimised the standard CDR model for subscription tracking, creating a seamless "value-first" experience. It started with a compelling pre-consent hook — "Never pay unwanted subscriptions again" — followed by minimal steps.

The typical CDR multi-screen burden was reduced to a 3-step core: Email → Bank → Accounts. Each screen used progressive disclosure — one decision per step — with explicit trust signals throughout.

Accredited via Adatree integration, Waave stayed fully compliant while humanising the experience — tying consent directly to a free, tangible benefit that users could see immediately.

Brand

From "Health Check" to a name people trust

The original working name — "Health Check" — felt clinical, generic, and couldn't be trademarked. Consumers wanted a personality, not a product label.

Names ending in the "ee" sound tested highest for approachability across AU, UK and US markets. Wendi was born: warm, memorable, trademarkable, and ready for global markets.

Design & UX

Mobile-first design, desktop ready

Wendi was designed mobile-first with desktop availability — matching how consumers actually check their finances.

Design Principles

How do you present transactional data in a way consumers can consume and stay engaged? We needed it to load quickly, so the design elements were minimalistic with information presented in a well-formatted way.

Fast Loading

Minimalistic design elements — no bloat, just clarity. Web-first with no app download.

📊

Well Formatted

Transactional data scrollable in date order. Clean hierarchy that's easy to scan.

Interactive Headline

Headline subscription number users could toggle to see the real impact of their spend.

Simple & Effective

Every screen designed for one action. Progressive disclosure kept cognitive load low.

Trust-Led Onboarding

The onboarding flow needed trust signals to overcome the data consent challenge. Time was invested in product messaging that led from the brand — giving Wendi a personality as an assistant who is helping you uncover any unknown subscriptions.

We used Look Who's Charging to provide accurate mapping of transactions to companies — displaying the correct merchant name and icon for visual recognition.

Direct quotes from beta testers.

"I just moved bank and used Wendi to check I moved all my subscriptions over. One came up which I'm sure I'd already moved."

"I felt the need to read through data policies… mostly due to a lack of trust in banks and what my bank may share."

"I love the concept of Wendi but it does not work for me for some reason."

"Potential to be a good tool if it works correctly."

Trust & Data Comfort

Users rated their comfort linking bank accounts at 4.4 out of 7 — reinforcing the CDR ecosystem's broader trust gap (only 0.31% national adoption by late 2023).

Consent Flow Connection: This mid-range trust score directly informed Wendi's "value-first" approach — showing savings estimates before asking for bank credentials, and reinforcing security messaging ("We'll never ask for your NetBank password") to bridge the comfort gap.

📊 Research Takeaway

The consent flow tested well (80% found it easy), but 39% reported missing subscriptions — highlighting the detection algorithm as the #1 area for improvement. The 4.4/7 trust score validated our consent UX strategy while revealing further opportunities to build confidence through transparency and value-first design.

September 2023

Australia's first instant-access, free subscription tracking tool

Wendi launched with a clear consumer proposition: connect your bank, see your subscriptions, find savings — free, in under 60 seconds. No app download required.

2024

Acquired by Banked

Banked specifically highlighted the work Waave and Chemist Warehouse were doing to create a low-cost, secure, engaging consumer experience for Pay by Bank — validating the land-and-expand thesis.

Waave's combination of Pay by Bank infrastructure and consumer-facing utility helped it establish enough traction to become an acquisition target — proving the commercial model worked.

Strategic Lessons

5 keys: Trust-first, funnel inversion, risk removal, value unlock, PLG monetisation

This case demonstrates how product, GTM, and strategy can work together in a regulated market — and offers a playbook for product-led growth with enterprise monetisation underneath.

1

Trust is the true constraint

In regulated data markets, trust — not technology — is the bottleneck. Waave identified this early and designed everything around earning it.

2

Start with the hardest part of the funnel

Consent is where most Open Banking products lose users. By making consent the easiest step, Waave inverted the typical drop-off curve.

3

Remove consumer risk first

Free, no download, no ID verification, no commitment. Every potential objection was eliminated before the user could think of it.

4

Create obvious value before asking for anything

Wendi gave users something tangible — subscription visibility and potential savings — before Waave asked for any commercial engagement.

5

Let value unlock the commercial engine

Product-led growth with enterprise monetisation. The free tool created consented data access, which supported Pay by Bank revenue — a model elegant enough to attract acquisition.

Commercial Model

Free land → consented data → Pay by Bank revenue → acquisition exit

The commercial logic was elegant: Wendi itself was free, but it increased the likelihood of consumer engagement with Waave's broader infrastructure — especially payment flows.

Waave's Pay by Bank proposition was built around lower merchant fees, instant authorisation, and a consumer experience that avoided card entry and reduced transaction risk.

Wendi was a strategic acquisition layer that supported future payments adoption. The company drew enough market relevance that Banked acquired Waave in 2024, citing its consumer experience and merchant relationships as part of the strategic rationale.

Pay by Bank advantages

  • Lower merchant fees vs card networks
  • Instant authorisation, no card entry
  • Reduced transaction risk and chargebacks
  • Consumer experience designed for trust
