How GrowthSpree Drove a 10X Jump in Daily Transactions for Salt
A full-funnel performance program across Facebook, Google Discovery, and LinkedIn that grew Facebook leads 7X at 50% lower cost — and now drives 80% of Salt's total leads through performance marketing.
The Mission
Salt is a neo-banking solution stitched together to ease payments and documentation, bringing business banking to a digital-first, automated, end-to-end platform. To grow, Salt needed a steady, efficient flow of high-quality leads that would convert into real transactions.
The Challenge
The goal was to optimize the entire funnel and bring down the global lead cost while maintaining lead quality. That meant finding the channels that actually fit Salt's target group, then scaling them efficiently — turning paid spend into both more leads and more daily transactions, without letting costs creep or quality slip.
Key Challenges Identified
Our Strategy
Optimize the full funnel: bring global lead cost down while protecting quality. After an initial month of testing, we concentrated budget on Facebook — the best fit for Salt's target group — unlocked Google Discovery as a high-quality lead source, and kept LinkedIn running for lead generation, scaling spend week over week as performance proved out.
The GrowthSpree Approach
We tested broadly on small budgets, then doubled down where the data led. Facebook emerged as the strongest channel for Salt's target group, so we scaled it with database lookalike and broad audiences. Google Discovery proved a gold mine for quality leads, using creatives already winning on Facebook and LinkedIn. LinkedIn continued contributing leads alongside both.
The throughline was funnel optimization: scale budget week over week while actively driving cost per lead down and protecting lead quality through continuous audience and creative refinement.
How GrowthSpree Saved the Day
Database lookalike and broad audience targeting, validated on small budgets and then scaled ~40% week over week. Leads grew 7X while cost per lead dropped 50% — taking Salt to 500+ leads a month at a very low CPL.
Google Discovery
Keyword-level targeting on Google Discovery with creatives proven on Facebook and LinkedIn. We scaled budget 20–30% week over week, reduced CPA capping 20–30%, and kept testing creatives — driving a 5X increase in leads with ongoing audience exclusions.
LinkedIn ran as a steady lead-generation channel alongside paid social and search, reinforcing the same audience and creative learnings to keep Salt visible to its professional, business-banking buyers.
Our Plan of Action: Test, Scale, Optimize
Find the channels that fit Salt's target group, scale them as performance proved out, and drive the global lead cost down without sacrificing quality.
Test Broad, Then Concentrate
Ran a testing phase across channels on small budgets to learn what worked, then focused spend on Facebook as the clear best fit for Salt's target group, with Google Discovery emerging as a high-quality second engine.
Scale What Works, Week Over Week
Applied small-budget learnings at scale — growing Facebook budget ~40% week over week and Google 20–30% — while actively reducing CPA capping so spend scaled without cost runaway.
Optimize the Full Funnel
Recycled winning creatives across Facebook, Google Discovery, and LinkedIn, and continuously excluded irrelevant audiences — driving the global lead cost down while protecting lead quality across the whole funnel.
