About
Firsthand builds an AI-powered Brand Agent Platform for enterprise marketers and publishers. Its agents help companies engage consumers directly through AI, while its Lakebed data and knowledge-rights layer gives organizations control over content access, data cooperation, and intellectual property.
Market
Firsthand competes in AI-powered customer engagement, conversational marketing, and brand-owned agent platforms. Its differentiation is shifting AI from back-end marketing or support automation to front-line consumer interaction: custom agents use approved brand or publisher knowledge to personalize conversations across websites, paid media, and partner sites, while Lakebed provides data and knowledge-rights control.
Firsthand targets consumer-facing brands and publishers, especially retail organizations with large product catalogs and financial-services providers with complex, high-consideration offerings. Likely buyers are marketing, digital-experience, audience-development, and publishing leaders seeking personalized consumer engagement while retaining control of proprietary data and content.

Problem
Brands and publishers are losing direct access to consumers as AI becomes a new layer for discovery and decision-making, while traditional digital advertising still tends to deliver static messages to a single destination. The resulting pain is both strategic and economic: companies risk surrendering their voice, proprietary knowledge, customer relationships, and data to technology gatekeepers, while missing opportunities to increase engagement, generate sales, and learn what customers actually need. Firsthand’s central use case is replacing static ads and disconnected journeys with real-time, guided conversations—for example, helping retail shoppers navigate large product catalogs according to their needs and preferences.
Product / Service
Firsthand sells an AI-powered Brand Agent Platform for marketers and publishers. Its Lakebed product is a data and knowledge-rights layer that lets a company control which content and expertise AI can access and how that information is used. On top of Lakebed, customers create custom Brand Agents—essentially AI-powered, context-aware mini-apps—that use approved brand knowledge to hold personalized conversations, answer questions, present content, and guide consumers across owned websites, paid media, and partner sites.
The benefit is a more direct and measurable consumer channel: agents can educate prospects, qualify leads, route people to relevant destinations, accelerate conversion, and generate richer first-party insight through interaction transcripts and explicit feedback. Publishers can also use the agents as an AI-powered advertising product that surfaces relevant content and creates new revenue opportunities while keeping readers engaged.
Market
Firsthand operates at the intersection of AI agents, marketing technology, ad tech, conversational commerce, and publisher monetization. It positions itself as the industry’s first Brand Agent Platform rather than a generic chatbot, with differentiation based on distributing agents across the web and combining conversational experiences with rights-controlled use of a brand’s proprietary knowledge. The competitive set is therefore broad: conventional marketing-automation and customer-engagement platforms are adjacent alternatives, with G2 listing monday AI Work Platform, HubSpot Marketing Hub, and HubSpot Sales Hub among Firsthand alternatives, although the available evidence does not establish them as direct like-for-like competitors.
The company appears to be in early commercial scale-up rather than demonstrably pre-revenue. Firsthand emerged from stealth in February 2024, raised a $26 million Series A in March 2025 from Radical Ventures, FirstMark Capital, Aperiam Ventures, Crossbeam Venture Partners, and angels, and said it was running 2025 campaigns for enterprise marketers and publishers. It also reported rapid growth and plans to double its workforce by the end of 2025. No public revenue figures were found in the available materials, so funding and enterprise campaigns—not reported revenue—are the clearest disclosed traction signals.
