SparkForce increases free trials by 140% with Funnel and LinkedIn

SparkForce, a Denmark-based growth marketing agency for B2B SaaS scale-ups, guided their customer Corpay One to improve their acquisition strategy. Early efforts produced a high volume of leads that lacked desired down funnel outcomes. To improve the strategy, SparkForce adopted Funnel’s Conversions API integration for LinkedIn. The new data foundation exposed underperforming audience segments and revealed where higher-intent buyers were actually coming from. With this visibility, SparkForce redirected budget toward audiences that were more likely to convert, reshaping Corpay One’s growth efforts. What followed was a measurable shift in efficiency, stronger conversion quality, and the company’s best month of free trials in three years.

Results: Lower costs, higher conversion quality, and record trial volume

- Offline conversion visibility enabled SparkForce to pinpoint the campaigns and segments driving the strongest outcomes, resulting in more efficient use of budget across the funnel.
- Improved budget allocation produced a dramatic efficiency gain, delivering 75% of all conversions with only 1/12th of the previous budget.
- Customer acquisition cost dropped by 88%.
- Monthly trials increased by over 4x between early summer and October, reaching the highest level the Corpay One had seen in years.

Thanks to Funnel’s LinkedIn CAPI integration, we managed to reduce our client’s customer acquisition cost by 88%, purely from getting the objective and segmentation right.”

Challenge: Gaining visibility into audience quality and campaign performance

- Lead generation campaigns were delivering high volumes of low-intent leads, with very few converting into free trials or customers.
- Existing last-click attribution in the client’s CRM produced inconsistent, unreliable data, limiting visibility into which LinkedIn campaigns contributed to meaningful outcomes.
- SparkForce lacked a clear view of audience quality, making it difficult to assess performance, optimize targeting, or justify further investment.

Solution: Building a reliable data foundation

- SparkForce has long used LinkedIn Ads to drive their own success. To help do the same for Corpay One, they implemented LinkedIn's Conversions API through Funnel, enabling a clear, accurate view of offline conversions.
- The team unified ad platform metrics with CRM outcomes in a single dashboard, giving SparkForce a dependable understanding of which campaigns, creatives, and segments were driving free trials and customers.
- A review of audience performance surfaced segments that weren't converting, leading SparkForce to shift smaller-company audiences into retargeting-only. The budget was then redirected toward the larger company segment to reach higher-intent buyers and support Corpay One's move upmarket.
- Creative and format choices were optimized across text ads, video featuring real people, image and GIF assets, and high-performing Thought Leader Ads.
