Multiply banks $9.5M to reinvent B2B ads for the AI era
As traditional B2B advertising struggles with rising costs and falling effectiveness, adtech startup Multiply has secured a $9.5 million funding round to rebuild how business audiences are targeted and engaged in the age of ChatGPT and privacy-first browsing.
The company is betting that legacy B2B ad platforms—built around third-party cookies, static segments and generic banner campaigns—no longer match how decision-makers actually research products. With buyers increasingly turning to AI assistants, niche communities and intent-rich content, Multiply aims to plug its technology into this new discovery journey.
An AI-native approach to intent and messaging
Multiply positions itself as an AI-native ad platform that uses machine learning to interpret real-time signals such as content consumption, search context and conversational queries. Rather than relying solely on broad firmographic filters, the platform builds dynamic profiles of in-market accounts and decision-makers.
On top of that, its AI models generate and test tailored ad creatives and landing-page copy, seeking to match the language and pain points of specific buyer groups. The goal is to lift conversion rates in a market where many B2B campaigns still recycle generic messaging across LinkedIn, trade media and programmatic channels.
Competing in a privacy-first, post-cookie landscape
The funding comes as the industry faces the demise of third-party cookies, stricter GDPR enforcement and growing scrutiny of cross-site tracking. Multiply says its platform is built around first-party data, contextual understanding and consented signals, rather than opaque tracking graphs.
That approach is designed to reassure both marketers and compliance teams who are wary of older B2B data vendors whose practices are being challenged by regulators. By integrating directly with a company’s own CRM, marketing automation and analytics tools, Multiply promises more measurable pipelines and less reliance on black-box attribution.
Can AI fix what’s broken in B2B ads?
Whether Multiply can truly “fix” decaying B2B advertising will depend on its ability to prove that AI-driven targeting and creative optimization deliver better pipeline, not just better click-through rates. Many enterprise marketers are already experimenting with generative AI, but struggle to operationalize it at scale and within brand and compliance guardrails.
With fresh capital behind it, Multiply is positioning itself as a bridge between classic demand generation and the emerging world where buying journeys are co-piloted by AI assistants. If it succeeds, the company could help redefine what effective, privacy-safe B2B advertising looks like in the ChatGPT era.
