Case Study: Sweet Influencers achieves faster, smarter creator matching with Sphere Partners

Sweet Influencers boosts influencer match relevance 5x with Sphere Partners

Sphere Partners worked with influencer marketing platform Sweet Influencers to address a key challenge in the franchising industry. The customer’s original platform relied on basic keyword search, which failed to find niche, local creators crucial for regional franchise campaigns. This resulted in marketers spending weeks manually sifting through hundreds of generic profiles to build a shortlist.

The solution involved Sphere Partners rebuilding the platform into a Gen-AI system featuring hybrid search (lexical and vector retrieval) and LLM-generated brand-fit summaries. This was combined with an automated campaign cockpit and CDN-backed media delivery. The delivered POC modeled dramatic improvements: shortlist time dropped from up to two weeks to under a day, search precision increased by over 40 percentage points, and profile asset load times were cut by roughly 72%.
