Aarhus, Denmark-based Serpier has raised €1.4 million in seed funding in a round led by True Collective, with participation from the Export and Investment Fund of Denmark, EIFO.

Founded in 2024, the startup develops AI-powered digital visibility and marketing optimization software for global e-commerce brands, with a focus on Generative Engine Optimization. Its platform is designed to help companies track how they appear across large language models and other AI-driven discovery channels.

Serpier said the new funding will be used to expand its platform and support product development, including automated LLM visibility monitoring, multi-channel citation trackers, and its AI agent orchestrator, Navi.

The round reflects continued investor interest in tools built around how search, discovery, and brand visibility are shifting from traditional search engines to generative AI interfaces.
