Delivery journey
Four steps from discovery to proof
Every case study follows the same discipline: clarify measurement, set up, optimise, prove the outcome.
Discovery & measurement
Accounts, conversion points and Finance & Fintech goals were mapped; leaks were found.
Setup
Channels connected, tracking fixed, campaigns and automation rules launched with approval.
Optimisation
Winning creatives/products scaled; under-threshold spend was capped or paused.
Measured outcome
33% lower CAC and 1.7x confirmed growth; the team returned to product and sales.
Challenge
Acquisition was accelerating but CAC rose unchecked. It was unclear which channel produced real LTV. The team spent hours on weekly reports without clear channel-level ROAS/CPA. In Finance & Fintech, late optimisation meant wasted spend and missed demand.
What we did
Tecrube connected channel conversion and cohort reports; rules capped spend when CAC thresholds broke. Creative testing accelerated. Tecrube gave PayNest control with approved actions, automated budget rules and creative health signals. Sales and marketing began sharing the same scores.
Outcome
CAC stabilised and 90-day active users rose. Growth decided with threshold rules instead of guesswork. Within the measurement window they saw 33% lower CAC; decisions shifted from guesswork to the panel.
We reined in cost without losing growth speed. That balance is what we needed.
Modules used
Key takeaways
- In Finance & Fintech, clarify measurement before scaling budget — cost drops faster.
- Keeping unapproved spend off raises both trust and speed.
- When lead or order scores connect to sales, channel debates end and results start.
