OuterSignal is a customer intelligence platform for e-commerce brands. Their order tells you what they bought. OuterSignal shows you who they are.
We tell brands 10x more about their customers than they know right now — age, occupation, property value, social following, family status, interests, education, and more — and use that to identify VIP customers, build precision segments, and personalize outreach at scale. Whether it's flagging celebrities, athletes, investors, podcasters, buyers at large retail chains, or surfacing micro-influencers within a target cohort, OuterSignal finds, flags, and activates the customers that matter most.
We built OuterSignal because every DTC brand has the same problem: you collect a name, an email, and a shipping address. You know nothing else about the person behind the order. You don't know if they're a journalist who could write about your brand, an influencer with 100K followers, an executive who could become a corporate gifting partner, or a repeat buyer whose property value and interests perfectly match your highest-value segment.
OuterSignal solves that.
What OuterSignal Does
OuterSignal connects to your e-commerce platform — Shopify, BigCommerce, or nearly any other via API — and enriches every customer with person-level intelligence: demographics, professional background, social media presence, interests, lifestyle indicators, and household context. New orders are enriched in real time, automatically, as they come in. Historical customers can be enriched via Back Search.
The core technical challenge we solved is figuring out who someone is from minimal data. There are dozens of people with the same name in any given city. We don't match names against a static database and hope for the best. We resolve identity dynamically from multiple signals simultaneously, achieving 98%+ accuracy across the platform for hundreds of brands.
Enrichment Depth
Every enriched customer profile can include:
| Category | What You Learn |
|---|---|
| Demographics | Age, gender, household composition, life stage |
| Professional | Occupation, employer, industry, job title, career history |
| Social media | Profiles across Instagram, TikTok, LinkedIn, X, and YouTube — follower counts, content themes, influence score |
| Interests | Hobbies, activities, lifestyle indicators, education |
| Financial | Property values, household context |
| VIP status | Influencer, executive, athlete, journalist, public figure detection |
This isn't audience-level estimation or a batch CSV dump you have to figure out how to activate. It's individual-level intelligence tied to a specific customer in your store, flowing into your marketing tools in real time.
Key Features
Signal Feed
The primary product surface. An enriched customer list with advanced filtering, sorting, and a Signal/Noise toggle that separates high-value customers from the full list. Keyword Search lets you find any term across your entire customer base — search "dermatologist" and see every customer who matches, search "yoga" and find the fitness community hiding in your orders.
AI-Generated Personas
OuterSignal groups customers into dynamically generated Personas based on their full enriched profile. Segments like "Executive Optimizer," "Performance Athlete," "Busy Suburban Mom," and "Ageless Achiever" aren't static demographic buckets. They're built from real identity data and designed to be immediately actionable.
Export Personas directly to Klaviyo as customer tags, push them to Meta Ads as custom audiences, or use them to target direct mail campaigns through PostPilot.
Playbooks (Automation)
Rules-based automation triggered by customer intelligence. Examples:
- A customer with 10K+ followers places an order → push VIP tag to Klaviyo, send a Slack alert, trigger an influencer outreach flow
- A customer identified as a retail buyer → notify the sales team via Slack and email
- A customer matching a custom-defined segment → tag in Klaviyo, add to a Meta audience, send a webhook to your CRM
Playbooks connect enrichment data to action without manual work.
VIP and Influencer Detection
Real-time identification of notable customers the moment they place an order. OuterSignal detects influencers, executives, athletes, journalists, and other high-value individuals automatically. Alerts fire via Slack and email so your team can respond immediately — not days later when someone happens to notice.
Integrations
OuterSignal integrates directly with the tools DTC brands already use. Intelligence that doesn't connect to your marketing stack is just a spreadsheet — and too many enrichment tools stop at the spreadsheet.
| Integration | What It Does |
|---|---|
| Shopify | Native app. 2-minute OAuth install. Real-time order processing. |
| BigCommerce | Native integration for BigCommerce stores |
| Any platform | Custom API and webhooks for WooCommerce, Stripe, or any e-commerce stack |
| Klaviyo | Push Persona tags, demographic data, and VIP flags directly into Klaviyo customer profiles. Trigger personalized email and SMS flows based on who customers are, not just what they bought. |
| Meta Ads | Export Persona-based audiences for lookalike targeting. Build custom audiences from enriched segments. |
| Slack | Real-time alerts when VIPs, influencers, or high-value customers order |
| PostPilot | Target direct mail campaigns using enriched segments and Personas |
| Braze | Enterprise email and messaging integration |
| Attentive | SMS personalization based on customer intelligence |
| Customer.io | Messaging automation with enriched customer data |
| Segment | Bi-directional data sync for brands using Segment as their data layer |
| BigQuery | Data warehouse sync for custom analytics and reporting |
| Custom API / Webhooks | Send enriched data anywhere your stack needs it |
The Klaviyo integration deserves special attention. Most brands using OuterSignal run their email through Klaviyo. When OuterSignal enriches a customer, it can push Persona tags and demographic attributes directly into Klaviyo, enabling email flows personalized by who the customer is — not just their purchase history. Gratsi ran an A/B test using this exact setup and saw +47.2% revenue and +54.1% click rate on persona-based email versus their standard flows.
Results
OuterSignal is trusted by hundreds of brands including Jones Road Beauty, HexClad, Mizzen+Main, Bloomscape, Comrad, OOFOS, Lucy, Momentous, Create, Gratsi, Rorra, and Carte Blanche. 95% retention.

These aren't hypothetical projections. They're results from real campaigns run by real brands using OuterSignal data.
How OuterSignal Is Different
We Built for Consumer Commerce, Not B2B
Most data enrichment tools were built for B2B sales teams. Their data model revolves around companies: firmographics, tech stacks, org charts. OuterSignal was built from day one for consumer e-commerce. Every feature, every data model, every integration is designed around the question DTC brands actually ask: "Who is this person buying from me?"
We Solve the Hard Problem: Identity
Figuring out who your customers are from a name, email, and shipping address is genuinely difficult. There are fifty "Sarah Johnsons" in any metro area. We don't match against a static database and call it a day. We resolve identity dynamically and in real time, which is why we maintain 98%+ accuracy at scale. If we can't confidently identify someone, we say so — we'd rather return no data than wrong data.
Real-Time Enrichment That Flows Into Your Entire Stack
Most enrichment tools hand you a CSV and wish you luck. OuterSignal is different. Everything it surfaces — Personas, VIP flags, demographic attributes — flows directly into the tools brands use every day, in real time, as orders come in. Klaviyo tags trigger email flows. Slack alerts notify teams the moment a VIP orders. Meta audiences power ad campaigns. Playbooks automate the entire chain from enrichment to outreach across your entire marketing stack. The loop from "who is this customer?" to "here's what we did about it" is closed automatically — no data dumps, no manual imports, no CSVs to wrangle.
We're Honest About Limitations
OuterSignal is US-focused. International customer coverage is limited to what's available from US shipping and billing addresses. We integrate with Shopify, BigCommerce, and nearly any other platform via API — but Shopify is our deepest native experience. We don't process Amazon order data. And our enrichment uses publicly available information only. We don't buy third-party consumer data, and we don't use customer data for AI/ML model training.
We'd rather be transparent about what we don't do than let you find out after you've signed up.
Five Ways Brands Use OuterSignal
1. VIP Detection and Gifting
Identify influencers, celebrities, executives, and high-value individuals the moment they order. Trigger upgraded shipping, handwritten notes, PR packages, or personalized founder emails automatically via Playbooks. Never miss another high-profile customer.
2. Persona-Based Email Personalization
Push OuterSignal Personas into Klaviyo and personalize email flows by who the customer is. An "Executive Optimizer" gets different messaging than a "Performance Athlete." Gratsi proved this drives +47.2% more revenue in a controlled A/B test.
3. Meta Lookalike Audiences
Export Persona segments to Meta Ads and build lookalike audiences based on who your best customers actually are — not just purchase behavior. Mizzen+Main's OuterSignal Personas were their #1 performing Meta audience over BFCM.
4. Direct Mail Targeting
Combine OuterSignal intelligence with PostPilot to send targeted postcards and mailers to your highest-value segments. Mizzen+Main achieved 20x+ ROAS targeting an executive persona with direct mail.
5. B2B and Wholesale Discovery
OuterSignal regularly surfaces hidden B2B opportunities in DTC customer bases: retail buyers placing personal orders, corporate gifting managers, wholesale prospects. One brand discovered 1,000+ warm B2B leads within 48 hours of activation.
