Affinect

Affinect helps hospitality businesses improve loyalty, retention, and guest engagement. Built for restaurants, cafés, beach clubs, entertainment venues, retail spaces, and multi-location operators, Affinect brings together customer data, digital loyalty, targeted campaigns, automation, and visitor intelligence on a single platform. The goal is simple: help businesses understand who their guests are, how often they return, what they respond to, and how to bring them back more effectively. Affinect supports loyalty programs, digital coupons, behavioral segmentation, guest profiles, campaign attribution, visitor analytics, and multi-location insights. Hospitality teams can segment guests by visit frequency, recency, location, birthday, campaign engagement, loyalty activity, or return behavior, then use that data to send more relevant communication across email, WhatsApp, SMS, and other connected channels. Guest WiFi and QR touchpoints can also be used as consent-based data-capture tools, helping businesses identify in-person visitors who would otherwise remain anonymous. Instead of relying only on social media, delivery platforms, paid ads, or disconnected booking systems, Affinect helps venues build a more useful first-party customer database from their existing guest traffic. The platform is designed for teams that want practical retention tools without adding unnecessary operational complexity. It helps marketing, operations, and leadership teams see which guests are returning, which campaigns are working, which offers are being redeemed, and where customer engagement can be improved. Affinect works with hospitality and experience-led businesses that want to move beyond generic promotions and build more measurable, long-term customer relationships.

Blotout

Blotout is first-party data infrastructure for performance marketers. iOS privacy changes, cookie deprecation, ad blockers, and consent regulation have quietly stripped away the conversion data that ad platforms need to optimize. Match rates drop. CAC climbs. Attribution gets fuzzy. Most teams accept this as the cost of doing business. We don't. Blotout runs on your domain — not a third-party pixel — and captures events at the edge before they get blocked, stripped, or lost. We stitch identities into a Persistent first-party ID graph, deduplicate against client-side pixels, and forward clean, enriched signals to every channel that matters: Meta CAPI, Google Ads, TikTok, Klaviyo, Pinterest, Snapchat, X, Mailchimp, Amplitude, Spotify, and 55+ more. The result: higher Event Match Quality, recovered conversions, lower CPAs, and reporting that reflects what customers actually do. GDPR and CCPA compliant with complete audit trails and data sovereignty. Our products: EdgeTag. Server-side tracking and identity infrastructure. One-click installation on Shopify, WooCommerce, BigCommerce, Magento, Salesforce Commerce Cloud, and custom stores. Sends server-side events to every major ad platform with first-party identifiers your client-side pixel can't capture. ConsentIQ. Built-in consent management and analytics. Tracks opt-in rates, regional consent breakdowns (EU, UK, CA), and category-level consent — without the GDPR compliance theatre. Who we work with: High-growth DTC and ecommerce brands, performance agencies running paid media for them, and headless commerce teams that need infrastructure-grade data control. From eight-figure Shopify stores to enterprise retailers, the pattern is the same: own your signals, own your identity graph, own the outcome. Why it matters: The new growth lever isn't creative or media. It's infrastructure. The brands winning post-iOS aren't outspending competitors. They're capturing signals their competitors lose. That's what we build. Stop renting your data from the platforms that lose it. Take it back.

OuterSignal

OuterSignal is a customer intelligence and enrichment platform for Shopify and direct-to-consumer brands. It takes the customer data a brand already collects through orders and adds context to it -- who the customer is, what they likely care about, and whether they're worth special attention -- so marketing, retention, and CX teams can act on a fuller picture of each shopper. The platform connects to a Shopify store in one click and begins enriching every customer profile, not just suspected high-value ones. For each customer, OuterSignal adds more than 100 attributes drawn from publicly available information, including occupation and seniority, demographic indicators, social presence, interests, and signals related to spending capacity. The result is a customer database that goes beyond email address and order history to describe the actual person behind each purchase. Brands use OuterSignal in four main ways: - Signal Feed. A live view of recent customer activity, filterable by segment, attribute, or recency. Teams use it to monitor incoming orders, surface notable customers, and spot patterns as they happen. - VIP Detection. Automatic flagging of high-value customers: executives, founders, celebrities, influencers, and other recognizable buyers. Influencer, CX, and retention teams can prioritize outreach instead of treating every order the same. - Segments and Personas. Audience definition using any combination of enriched attributes, plus AI-generated personas that group customers into recognizable buyer types. Segments stay updated as new orders come in. - Outbound Sync. Enriched customer data is sent to the tools brands already use, including Klaviyo, HubSpot, Postmark, and Slack, so the same enrichment powers email flows, CRM records, and team alerts. OuterSignal is built specifically for Shopify and Shopify Plus stores. Installation is one click, billing runs through the Shopify Billing API, orders and products sync automatically through native webhooks, and historical orders can be backfilled at install. Brands not on Shopify can connect through CSV import and direct subscription. Typical use cases include identifying VIPs the moment they place an order, building segments based on attributes that aren't visible in Shopify alone (such as professional context or interest categories), personalizing email and SMS flows with richer audience definitions, and giving CX teams more context on who they're talking to. OuterSignal is intended for growth, retention, lifecycle, and customer experience teams. It is most relevant to operators who feel that Shopify, Klaviyo, and similar tools describe what customers do but not who they are, and who want that gap closed without manual research or a data-engineering project.
