BauPay — FINTECH STARTUP LAUNCH

the challenge

NEW PRODUCT. NO MARKET HISTORY.

The startup had to explain a new payment workflow to a conservative B2B audience and learn which promise produced action.

our solution

FOUR TESTS. OFFER TESTING ONE CLEAR COMPARISON.

We separated the trial message, lead forms and profile traffic so the team could see which campaign produced which response.

  1. 01

    DIAGNOSE

    Mapped how conservative construction buyers actually evaluate a new payment workflow.

  2. 02

    SEGMENT

    Split the trial offer, lead forms and profile traffic into separate tracks instead of one blended message.

  3. 03

    TEST

    Tested the low-friction trial message against lead-form and profile-traffic variants on controlled budgets.

  4. 04

    OPTIMIZE

    Shifted spend toward the offer-channel combinations that produced real leads, not just clicks.

  5. 05

    REPORT

    Reported the 76 leads by campaign, cost and month, so the team could see which signal to trust.

who this is for

BEST FOR TEAMS THAT NEED RESULTS.

For teams launching an unfamiliar product that need to test the offer and measure early interest before increasing spend.

  • You are planning a regulated fintech demand test and need cost and lead volume separated by campaign and period.
  • You're launching a new or unproven offer and need to learn what converts before you scale spend.
  • You want reporting scoped to what the data proves — channel, period and cost — not vanity metrics.

timeline

HOW THE SYSTEM WENT LIVE.

  1. Foundation

    Defined the audience, the trial message and what counted as a lead.

  2. Build & ship

    Ran four separate campaigns for the trial offer, lead forms and profile traffic.

  3. Compound

    Compared cost and lead volume, then moved budget toward the clearer signal.

asked about this case

Was this a one-off campaign or a system?

A system: four campaigns tested the offer, lead forms and profile traffic in parallel over two months, and spend moved to what worked.

Would the same test make sense for our product?

It depends on whether the offer can be tested with one clear action and a controlled budget. We can check that before recommending a campaign.

What was broken?

New payment product for construction companies; conservative B2B audience; no market history. Needed to learn which promise produced action.

Leak: demand (untested offer).

What we did

Separated trial message, lead forms and profile traffic. Four campaigns on controlled budgets. Shifted spend to combinations that produced real leads. Reported by campaign, cost and month.

One number that moved

76 Meta leads across 4 campaigns · Jan–Feb 2026.

Weighted CPL €13.13; spend €998.21 across those four lead campaigns in the same window.

Boundaries:

  • 76 / €13.13 / €998.21 = Meta lead flight Jan–Feb 2026 only — not revenue, not activated merchants, not LTV.
  • Leads ≠ sales. Early demand signal for an unfamiliar offer.
  • Do not blend profile-traffic vanity with lead totals.

What we refused

One blended message for trial + forms + profile. Scaling spend before a clear lead signal.
