Brands know when an order comes in, but they only see ~5% of the real story. We show them the other 95%: not just who bought, but who that person is - the execs, influencers, journalists, retail buyers, investors, and everyday customers who become a brand’s best evangelists. Our platform enriches every order in real time with professional + personal signals, unlocks personas, and powers everything from surprise-and-delight outreach to smarter email flows, analytics, and BD leads. We're a small, high-performing team building the category-defining platform for e-commerce customer intelligence, backed by a world-class investor base. What You’ll Do: - Architect and own core systems that process millions of orders across APIs and LLM pipelines - Build queue-based microservices using Redis, Node.js, Typescript, Postgres, Docker/K8s, Vercel - Integrate vector databases + RAG pipelines to make customer profiles smarter, faster, and searchable in real time - Ship features end-to-end: APIs, dashboards, integrations (Shopify, Klaviyo, Slack, Zapier, Gorgias) - Keep us ahead on privacy & compliance - Work directly with Founding Team on roadmap, product direction, and hiring future engineers Who You Are: - 5+ years engineering experience, ideally with backend infra + distributed systems - Experience in a fast-paced startup or willingness to dive in to a dynamic, changing environment - Fluent in JS/TS (Node), with some Python/ML exposure a plus - Experience with vector databases (Pinecone, Weaviate, pgvector, etc.) and RAG architectures - Comfortable designing schemas + scaling Postgres - Bonus if you’ve built around LLMs, Shopify apps, or data-privacy frameworks - Most importantly: you want ownership. You like to build quickly, solve “figure-it-out” problems, and aren’t afraid of messy early-stage work. Why Join Now: - Early seat: This is shaping the DNA of OuterSignal’s engineering org. - Massive upside: Meaningful equity in a venture-backed company defining a new SaaS category - High leverage work: You’ll see your code directly impact customers, revenue, and growth - Big surface area: From AI pipelines to Shopify apps to RAG/vector search infra, you’ll touch it all - Right moment: We’re past prototype, real brands already rely on us and have PMF, but the ceiling is wide open ## About OuterSignal ## Company Overview - **One-liner**: OuterSignal provides an AI-powered customer intelligence platform that helps e-commerce and DTC brands identify VIP customers, enrich customer profiles with demographic data, and personalize marketing across channels. - **Entity Type**: Private (early-stage startup) - **Headquarters**: Wilmington, Delaware, United States - **Founded**: 2025 - **Founders**: Zach Zelner (CEO & Co-founder), Noah Friedman (Co-founder) ## Core Business - **Primary industry/industries**: Customer Intelligence, eCommerce Analytics, Marketing Technology (Martech) - **Target customers**: B2B; Direct-to-consumer (DTC) brands and e-commerce stores, specifically those using Shopify and other major e-commerce platforms. - **Mission or purpose statement**: "Every brand should know who’s actually buying." Their mission is to rebuild the customer relationship in e-commerce, which they believe has been "hollowed out by ad networks, marketplaces, and middlemen." ## Products & Services - **OuterSignal Platform**: The core SaaS product acts as an "automated, real-time researcher." It integrates with a brand's e-commerce platform to: - **VIP Customer Detection**: Instantly identifies celebrities, influencers, athletes, and strategic partners within a brand's order history. - **Customer Persona Clusters & Deep Analytics**: Enriches customer data with demographic attributes (age, occupation, property value, social following) for advanced segmentation and analysis. - **Precision Personalization**: Allows brands to create highly targeted segments for export to Meta and CRM platforms, moving beyond purchase history to target *who* the customer is. - **Real-time Notifications**: Alerts via Slack or email when a high-value customer places an order. - **Pricing Tiers**: Starter ($49/month), Pro ($199/month + $0.03/unique new customer), Enterprise (custom pricing). Their pricing model is unique: brands only pay to process a customer the first time; returning customer orders are free. ## Market Standing - **Valuation/Market Cap**: Not publicly available (early-stage private company). - **Key Metric**: Total funding raised of $4.3M (Convertible Note) as of a recent round, 2026. - **Notable Investors/Partners**: Backed by Top Shelf Ventures (led by Daniel Noah). Partners include Klaviyo, Shopify, Zapier, and PostPilot. Powering "hundreds of the fastest growing brands" including HexClad, Jones Road, and Jolie. - **Growth Signals**: - **Recent Acquisition**: Acquired Monocle, an AI-powered lifecycle marketing platform, in May 2026 to build an integrated AI personalization stack. - **Workforce Growth**: Monthly employee growth rate of +10.5%, with 11 employees currently. - **Customer Results**: Case studies show a +47.2% revenue lift from persona-based email campaigns and 20x+ ROAS on direct mail. ## Competitive Advantages - **"Glass Box" AI**: OuterSignal positions itself as transparent ("from black box to glass box"), giving brands clarity on *who* their customers are rather than just opaque, AI-generated segments. - **High Match Rate**: Claims a 94% match rate for enriching customer data, which is critical for personalization efficacy. - **Founder-Market Fit**: Built by founders with deep DTC operational experience (ran 45+ Shopify stores, built and sold multiple DTC companies), solving a problem they directly encountered. - **Unique Pricing Model**: The "pay per new customer" model is a significant moat, as processing returning customers becomes free, aligning the cost with customer acquisition value. ## Strategic Focus - **AI Agentic Intelligence**: Focus on building autonomous AI agents (as highlighted by the Monocle acquisition) to automate complex, personalized customer journeys across email, SMS, and web. - **Platform Integration**: Deepening integrations with major e-commerce and marketing platforms (Klaviyo, Meta, Shopify) to become a central data layer for DTC brands. - **Enterprise Expansion**: Moving upmarket with Enterprise plans that offer white-glove onboarding and dedicated support for high-volume brands (30,000+ orders/month). ## Why Work Here - **Founding Team & Culture**: The leadership is composed of seasoned DTC operators and engineers from companies like Zapier, Box, and Glassdoor, creating a culture built on solving hard operational problems. - **Early Stage Impact**: With only 11 employees and rapid growth, new hires would have massive ownership and direct impact on the product and company trajectory. - **Technical Environment**: The tech stack is modern (Docker, TypeScript, Python, Redis, Microservices), suggesting a strong engineering culture focused on building scalable, data-intensive systems. - **Remote Work Policy**: Not explicitly stated as remote or in-office, but the small team size and modern tech stack suggest a high degree of flexibility. - **Active Hiring**: Currently has 5 open roles including Senior Software Engineer, Account Executive, and Sales Development Representative, indicating a growth phase where early employees can shape the company. ## Sources 1.
