Stop showing the same banner
to every visitor.
Most retailers serve generic banners — wasting 15-30% of potential conversions on mismatched creative. For a chain doing $1M/mo in banner-attributed revenue, that’s $150k–$300k left on the table every month.
Busyfolder’s Persona API infers visitor taste from location and context, returns the ideal banner plus an impression_id for conversion tracking. One call, under 60ms.

What works in Miami
Probably won’t work in Minneapolis.
Every city has a different rhythm. Different weather. Different crowds. Different needs. Your banners should match the moment.

Render the winning banner
Use external_id to fetch the creative from your CMS and display it. That’s the integration.
Close the feedback loop
On CTA or purchase, POST /api/persona/convert with the impression_id. Each conversion improves future selections — no training data required.
Node SDK also available:npm install @busyfolder/persona
Measurable conversion lift — in 2 weeks, not 2 quarters
No ML team. No vendor lock-in. No long-term contract.
The cost of inaction
Generic banners in Miami look the same as Minneapolis. That’s not a personalization gap — it’s a revenue leak.
If you’re showing the same banners everywhere, you’re losing an estimated 15-30% of potential conversionsto mismatched creative.
The math: A 350-store chain averaging $2M/store/year in banner-attributed revenue is leaving $300k–$900k/yearon the table with generic banners. That’s not a theoretical loss — it’s budget already spent with nothing to show.

Why it works
“Generic banners cost you conversions. Personalized banners earn them back.”
Transparent scoring
15+ real-world signals scored against your banner tags via weighted affinity matrix. Not a black box. You can explain why a banner was chosen.
Your CMS, your content
We return an external_id. You fetch the creative from DatoCMS, Contentful, Sanity, Shopify, or your own system. Zero vendor lock-in.
Integration: one endpoint
POST /api/persona/select to choose. POST /api/persona/convert to track. A single developer can ship it in a sprint.
No-risk pilot
No long-term contract. No ML team required. If you’re not seeing lift in 30 days, you walk away. We provide SLA and DPA for all pilots.
How it works — one call, six signals, one banner
Every selection runs through the same pipeline. No manual rules. No black boxes.
1. POST a ZIP + banner list → we fetch 15+ signals
Real-world signals — weather, local happenings, demographics, and market conditions — all gathered from public data sources, never from browser fingerprints or cookies.
2. Signals → visitor context tags
Heat wave → hot_weather. Festival nearby → concert_attending. Affluent POI density → affluent. Coffee shop concentration → coffee_culture. Budget-friendly area → budget_shopper.
3. Banner tags vs. visitor tags → weighted affinity score
Each banner has tags. Each visitor has context tags. The affinity matrix scores every combination — not binary match/mismatch, but weighted affinity from 0 to 1. Transparent and explainable.
4. Best match serves. Challenger explores 15% of the time.
Highest-scoring banner serves. When the top 2 scores are within 0.15 of each other, we explore the challenger 15% of the time — discovering high-performers without wasting traffic. Decisions cached 15 minutes per visitor for stability.
5. POST impression_id → convert → feedback loop closes
Each /convert event feeds back into the scoring engine. Banners that convert get higher affinity weights. Banners that don’t get deprioritized. The system improves with every conversion — no manual training, no ML team.

DatoCMSShopifyWhat teams are saying
Real feedback from retailers who’ve integrated the Persona API.
“We integrated the Persona API into our DatoCMS workflow in under three weeks. The first month showed a +9% conversion lift across our 350 stores — and we didn't hire a single data scientist.”
VP of Digital
Regional Grocery Chain
DatoCMS“What sold us was the 2-week pilot. We ran it on 20 stores, saw +12% CTR on personalized banners, and rolled out to all 500 locations the next month. The ROI was immediate and measurable.”
Director of Marketing
Franchise Convenience Chain
Shopify“One developer integrated it in a single sprint. The feedback loop — impression_id → convert — meant we could A/B test banners and let the data decide. No ML team, no months of waiting.”
CTO
Midwest Retail Group
“We were showing the same summer promo in Phoenix and Portland. The API caught the difference — weather, local events, demographics — and served banners that actually matched each market. CTR went up 10% in the first week.”
E-Commerce Manager

Stores already live. Beta capacity is filling.
We’re onboarding by cohort to maintain quality. Current wait time for new sandbox keys: ~2 days. 95% of stores that pilot stay on.
Your visitors’ privacy is built in, not bolted on.
Most personalization tools rely on browser fingerprints, third-party cookies, and cross-site tracking. Busyfolder takes a different approach — we infer taste from public data and location context. Nothing invasive. Nothing to install.
No browser fingerprinting
We never generate or read visitor fingerprints. No canvas, no WebGL, no nonsense.
No third-party cookies
No tracking cookies, no consent banners required. Just a ZIP code in, a banner ID out.
Public data only
Weather, demographics, nearby POIs, local events — all pulled from public sources. No PII ever leaves your servers.
Your visitors are different in every city.
Your banners should be too.
One API call, under 60ms, no ML team required. The fastest way to stop showing the same banner to every visitor.
Sandbox access: free, no card required. ~60s to first API call.
