Serpier Raises €1.4M: Inside the AI Agent That Automates E-Commerce Visibility Across Search and Chatbots

Danish martech startup Serpier has raised €1.4 million in a seed round (also reported as approximately $1.6M) to expand its AI-powered marketing platform that helps e-commerce brands show up in both traditional search results and AI chatbot responses . The round was led by True Collective with participation from the Export and Investment Fund of Denmark (EIFO) .

Founded in 2024 in Aarhus, Denmark, by Steffen Sørensen, Simon Holm, Søren Fuhr, and Thomas Grástein, Serpier has grown to 19 employees and reports generating more than €2.5 million in revenue in its first financial year while reaching profitability . Some sources cite revenue as high as €3 million .

What Serpier Does: Generative Engine Optimization (GEO)

Serpier is an AI-powered marketing platform focused on Generative Engine Optimization (GEO) — the practice of monitoring and improving how products and brands appear in AI-generated answers and LLM citations . Unlike traditional SEO, which optimizes for Google's ranking algorithm, GEO optimizes for how large language models like ChatGPT, Gemini, Claude, and Perplexity retrieve and cite information .

The platform monitors AI visibility across models and prompts, tracks citations and share of voice, and distributes brand mentions across a network of 200,000+ publisher outlets .

Meet Navi: The AI Agent That Runs Marketing Execution

Serpier's flagship product is an AI agent called Navi, which handles search visibility optimization end-to-end: it identifies opportunities, generates relevant content, and publishes it automatically . Navi's current capabilities include:

• AI visibility monitoring across multiple AI models and prompts
• Citation and share-of-voice tracking for brands and competitors
• Content generation and distribution across 200,000+ publisher outlets
• Link matching with a proprietary relevancy score

Navi is designed as an "AI marketing operator that executes for you," with an MCP integration that lets users connect Claude, ChatGPT, and Gemini directly to the Serpier workspace — allowing them to ask questions, build strategies, and place orders from within their existing chat interface .

The Roadmap: From Search Visibility to Full Marketing Automation

Serpier plans to expand Navi into a broader marketing automation workspace covering :

• Campaign management
• Landing page generation
• Advertising management
• Additional automation features beyond search optimization

The goal is to move Navi from a search-visibility tool to an autonomous marketing operator that can execute a wide range of marketing activities .

The Big Idea: AI Agents Handle Execution, Humans Handle Strategy

Serpier's stated vision reflects a broader shift in marketing: AI agents will handle tactical execution — content production, campaign optimization, publishing, and monitoring — while humans focus on strategy, creativity, and high-level decision-making .

This agent-led approach is part of a larger trend in martech, where platforms are increasingly embedding autonomous AI agents to replace repetitive, manual workflows . Serpier is one of the early movers in applying this specifically to Generative Engine Optimization — a category that barely existed two years ago but is now essential for any e-commerce brand that wants to be recommended by ChatGPT or Google AI Overviews .
