What actually changed, situation by situation
Chapter 01
Influencer matching isn’t a keyword problem — it’s a fit problem.
Generic search misses the local, niche creators that move sales in a franchise market. The cost shows up as wasted campaign budget and weeks lost to manual research.
The platform serves franchise marketing teams across quick-service restaurants, fitness studios, retail concepts, and home-services chains. In these environments, the buying decision is often made at the metro level by a creator the corporate marketing team has never heard of. The right micro or nano creator for a 12-store regional rollout is rarely the same person a keyword search surfaces first.
Before Sphere engaged, the platform relied on basic keyword search and a thin embedding summary. The user workflow was effectively: query the catalog, export a few hundred profiles, open each one in a new tab, read recent posts, review previous brand work, and score by gut. A single 15-creator shortlist for a regional campaign could take one to two weeks — and the resulting list was still hard to defend beyond the person who built it.
The opportunity was not a faster keyword search. It was a system that understood the brief, the brand, and the creator at the same time — then turned that understanding into a workflow a marketer could act on without leaving the screen.
Chapter 02
Hybrid search first, language models second.
Lexical and vector retrieval narrow the universe to candidates that match both literally and semantically. Only then does the LLM weigh in — to summarize, score, and explain.
Sphere rebuilt the search layer as a hybrid pipeline. Lexical retrieval over the creator catalog — display name, location, vertical tags, and recent post text — runs in parallel with vector retrieval over a custom embedding space tuned to brand-fit signals: audience composition, post topicality, sponsorship recency, and content production quality. The two result sets are fused with reciprocal-rank scoring before the LLM ever runs.
Only then does a large language model take over. For every shortlisted creator, the model emits a structured brand-fit summary: who this creator’s audience is in this metro, what they’ve sponsored recently, where the alignment with the current brief is strongest, and — importantly — where the risk is. The output is JSON, not free text, so the cockpit can render it as scannable cards instead of paragraphs.
The split matters for cost and for trust. Lexical and vector retrieval are cheap and deterministic; the LLM runs only on the ~30 candidates that survive retrieval, not the whole catalog. And because the search ranking is reproducible without the LLM, the platform can show campaign managers exactly why a creator surfaced — even when the brand-fit narrative was generated.
Chapter 03
What the end-to-end POC looks like, on paper.
Numbers below are modeled from the delivered scope and published franchising-marketing benchmarks. Each range reflects baseline variability across published studies and comparable Sphere engagements.
The numbers behind the engagement
| Metric | Before | After | Delta |
|---|---|---|---|
| Shortlist time per campaign (15 creators) | 10–14 days | < 1 day | −85% to −95% |
| Campaign brief generation | Manual · 2–4 hrs | AI draft · < 5 min | −95% |
| Cockpit lifecycle states automated | 0 / 11 | 11 / 11 | Full coverage |
| Staging deploy frequency | Ad-hoc · weekly | Automated · per commit | 5× faster |

Chapter 04
The secondary effect we didn’t design for: marketer leverage.
When campaign briefing, creator selection, and asset review live in one interface, the same team can run more campaigns.
The Campaign Influencer Cockpit codifies an 11-state lifecycle — from initial outreach through contract, content delivery, payment, and post-campaign reporting — into a single board view. The Leads module generates the briefs, contracts, and outreach drafts that previously lived across separate tools and shared drives.
Industry benchmarks for franchise marketing teams put creator-campaign cycle time at six to eight weeks per campaign when run through traditional agency or manual workflows. Comparable AI-augmented marketing workflows can reduce that to two to three weeks once the team clears a four- to six-week ramp. On a 12-campaign-per-quarter operating tempo, that creates roughly 30–40 additional campaign-weeks per quarter without adding headcount.
For franchise clients running similar playbooks across hundreds of locations, that throughput difference is the gap between running one regional test and running a repeatable, localized campaign engine.

Frequently asked questions
The platform helps franchise marketing teams identify local micro and nano creators who are a strong fit for a specific campaign brief. Instead of ranking creators by generic popularity or keyword matches, it evaluates campaign context, audience fit, location relevance, recent content, sponsorship history, and risk signals.
Sphere rebuilt the product into a Gen-AI workflow for influencer discovery and campaign management. The delivered POC includes hybrid search, LLM-generated brand-fit summaries, campaign-aware creator ranking, an AI Campaign Agent, an 11-state Campaign Influencer Cockpit, document generation for briefs and outreach, CDN-backed profile assets, and automated staging deploys.
Franchise marketing is local. A creator who moves sales in one metro may not be the creator a national keyword search surfaces first. Franchise teams need creator recommendations tied to local audience overlap, campaign relevance, brand risk, and the specific market where the campaign will run.
A generic influencer score usually prioritizes popularity, reach, or broad engagement metrics. Campaign-aware fit scoring evaluates whether a creator is right for a specific brief. It considers audience alignment, geography, recent content, sponsorship patterns, and risk signals, then explains why the creator belongs on the shortlist.
Sphere delivered the POC to staging with automated CI and a clear production handoff path. The work covered search architecture, LLM workflows, ranking logic, cockpit UX, profile media delivery, staging infrastructure, and production-readiness planning.
The current status is POC delivered and pre-production. The workflow is functional in staging, while production readiness and third-party data provider integration are being finalized. Production-measured numbers should be added after launch.
Yes. The same architecture applies to any product where users need to find, rank, summarize, and act on complex records: creator marketplaces, sales intelligence platforms, recruiting tools, vendor directories, compliance workflows, and other domain-specific search products. Sphere can scope the search layer, LLM workflows, cockpit UX, and infrastructure required to move from concept to staging.
