CustomerOS

CustomerOS is a London-based business-to-business software platform that consolidates fragmented customer data to help go-to-market teams identify high-fit leads silently engaging with their brand. The enterprise technology company provides a centralized infrastructure designed to bridge the operational gap between marketing and sales departments by tracking previously unrecorded digital interactions. Operating with an initial core team of five employees, the software provider utilizes a subscription-based pricing model tailored specifically for modern commercial organizations. The startup has raised approximately $2.6 million in pre-seed funding to scale its operations and further develop its data integration capabilities. This early-stage capital was secured with backing from prominent institutional investors including Y Combinator and Seedcamp, alongside financial contributions from more than thirty independent angel investors. CustomerOS was founded in early 2022 by former Voxbone executives Matt Brown, Jonty Knox, and Vasilica Coscotin.

High-Level Overview

CustomerOS is a B2B go-to-market (GTM) platform that helps companies uncover high-fit leads already silently engaging with their brand—prospects who browse websites, consume content, and evaluate solutions but never fill out forms. The platform uses a team of AI agents to detect in-market behavior, score leads against a company’s ideal customer profile (ICP), and surface real-time, actionable insights on who to target, how to win, and what messaging and content actually convert. It’s designed to eliminate “pipeline blindness” by turning anonymous website traffic into a qualified, sales-ready pipeline.

CustomerOS primarily serves B2B SaaS and tech companies that struggle with inefficient lead generation, low conversion rates, and misalignment between marketing and sales. By combining intent data, behavioral signals, and AI-driven recommendations, it enables GTM teams to focus on high-intent accounts and shorten sales cycles. The company has raised $2.6M in seed funding, is backed by Y Combinator, Seedcamp, Crane, and Cocoa, and is positioned as a “GTM copilot” that delivers measurable ROI in under 90 days, with a zero-risk pricing model that charges only after the first meeting is booked.

Origin Story

CustomerOS was founded in 2022 by Matt Brown and Jonty Rhodes, the same team behind Voxbone, a cloud communications company that achieved a $519M exit in 2020. Drawing from their experience scaling a global B2B SaaS business, they identified a recurring pain point: most high-fit, in-market leads never raise their hand by filling out forms, making them invisible to traditional lead gen and CRM systems. This “pipeline blindness” meant sales and marketing teams were often chasing low-intent prospects while missing the accounts that were already evaluating their product.

The idea for CustomerOS emerged from the GTM platform they wished they had at Voxbone—one that could automatically identify in-market accounts, score them against their ICP, and tell them exactly who to target and how to win. After building an early version that dramatically accelerated their own pipeline, they spun it out into a standalone product. The company launched publicly in 2023, quickly gaining traction with early adopters who reported rapid meeting generation and high close rates. Today, CustomerOS is based in London and has grown to a team of around 16 people, backed by top-tier investors in the European and global startup ecosystem.

Core Differentiators

AI-Driven GTM Copilot
- A “squadron” of purpose-built AI agents (e.g., The Researcher, The Competition Beater) that analyze behavior, intent, and engagement to surface high-fit leads.
- Automatically builds and refines ICPs based on real buying behavior, not just firmographics.

Real-Time Pipeline Discovery
- Identifies in-market accounts from anonymous website traffic, content consumption, and ad engagement.
- Scores buying stage and intent in real time, alerting sales with the right messaging and content at the right moment.

Actionable, ROI-Focused Insights
- Turns behavioral and spend data into strategic recommendations: where to double down, what to cut, and which accounts are ready to buy.
- Designed for both SDRs (who to reach out to) and decision-makers (how to allocate budget and resources).

Zero-Risk, Outcome-Based Pricing
- Pay only after the first meeting is booked, aligning incentives with customer success.
- No credit card required to start, lowering the barrier to trial and adoption.

Built by Operators, for Operators
- Founded by founders with a proven track record in B2B SaaS and GTM execution.
- The product reflects hard-won lessons from scaling a company to a $519M exit, making it highly relevant for growth-stage startups and mid-market SaaS companies.

Role in the Broader Tech Landscape

CustomerOS sits at the intersection of three powerful trends: the collapse of traditional lead generation, the rise of intent-based GTM, and the shift toward AI-native sales and marketing tools. Privacy changes (e.g., cookie deprecation), the fragmentation of search traffic due to AI, and the evolution of enterprise buyer behavior have made form-based lead capture increasingly ineffective. As a result, “pipeline blindness” has become a systemic problem for B2B companies, especially in competitive SaaS markets.

CustomerOS is riding the wave of AI-powered GTM platforms that treat the entire buyer journey as a data problem. Instead of relying on static ICPs and manual outreach, it treats intent signals, content engagement, and behavioral data as the primary inputs for pipeline generation. This aligns with the broader shift toward account-based, data-driven, and AI-augmented sales and marketing. By turning anonymous traffic into a qualified pipeline, CustomerOS is helping redefine how B2B companies think about demand generation, making it a key player in the next generation of GTM infrastructure.

Quick Take & Future Outlook

CustomerOS is well-positioned to become a core component of the modern B2B GTM stack, especially for SaaS companies that need to do more with less and prove ROI quickly. Its operator-led DNA, strong early traction, and compelling use case—“this thing prints meetings”—give it a clear edge in a crowded market. As AI agents become more sophisticated and intent data becomes more critical, CustomerOS is likely to expand its capabilities into predictive forecasting, dynamic ICP optimization, and deeper integration with CRM and sales engagement tools.

In the near term, the company will likely focus on scaling its customer base, expanding its AI agent suite, and deepening integrations with key platforms (e.g., HubSpot, Salesforce, LinkedIn, ad networks). Over time, it could evolve into a full GTM operating system, orchestrating not just pipeline discovery but also playbooks, content strategy, and cross-functional alignment. For investors and operators alike, CustomerOS represents a timely bet on the future of B2B growth: less spray-and-pray, more signal-driven, AI-powered GTM.
