  • Merchantee

    Participated · Seed · Jun 2026

    Merchantee provides a platform that consolidates catalogue, pricing, and campaign data across supported marketplaces and uses AI to recommend and execute actions such as repricing products, selecting promotional campaigns, and optimising catalogue performance. The system operates at the individual product level and can adjust pricing at regular intervals while enforcing seller-defined rules. Merchantee aims to help sellers manage marketplace complexity without materially increasing headcount or operational resources. It is already used by hundreds of sellers and digital commerce teams, including customers such as Philips, Lindt, SodaStream, and Vilgain. The company plans to expand geographically across Europe—starting with Poland and Germany—and to add integrations with marketplaces like eMag, BOL, and Cdiscount. Merchantee is also developing autonomous decision-making capabilities and exploring longer-term agent-to-agent commerce models. The company recently raised €1.8 million to support these product and expansion initiatives.

  • BeatpulseLabs

    Led · Seed · Jun 2026

    BeatpulseLabs converts domain-specific human expertise and raw multimedia assets into structured, annotated, model-ready training datasets for multimodal AI. The company offers two integrated services: dataset preparation (cleaning, structuring, labelling, validating, enriching, and formatting speech, music, and video) and dataset provision of ready-made and custom rights-cleared datasets. Its datasets are positioned to support model training, fine-tuning, reinforcement learning, and evaluation to improve context awareness and reliability. BeatpulseLabs reported 10x revenue growth during the first half of 2026, indicating accelerating enterprise demand. The company was founded by Jason Rieff and Nikolay Vitanov. The new pre-seed funding will be used to expand the platform and scale the customer base.

  • Ranketta

    Led · Seed · Nov 2025

    Ranketta provides a SaaS platform that measures how often and how prominently brands and products appear in AI-generated answers across tools such as ChatGPT, Gemini, Perplexity, and Google’s AI Overview. The software surfaces product-level and brand-level insights, including sentiment, relative ranking, frequency of mentions, and the specific sources LLMs cite. An integrated AI Copilot analyzes this data to recommend content changes and citation targets that can boost a brand’s placement in AI search results. In its first two months on the market, the platform has onboarded more than 20 European brands, including Brainmarket and Boost.space. Founded in 2025 by 21-year-old Czech engineer and AI researcher Vojtěch Oravec, the company was inspired by his work at the Czech Institute of Informatics, Robotics and Cybernetics. Ranketta plans to deepen integrations with Shopify and other e-commerce platforms while scaling engineering, product, and sales teams. With €1 million in pre-seed capital now secured, the company is targeting rapid expansion across Europe and an entry into the U.S. market.

  • FleetFox

    Led · Equity · Nov 2025

    Founded in 2017 in Tallinn by Martin Kristerson and Valjo Kütt, FleetFox provides a unified technology platform that lets corporate fleet owners manage car washing, fueling, relocation, maintenance and inspections in one place. The company runs on a pay-per-task model and equips customers with route optimization, live tracking and automated invoicing to cut operational costs and boost efficiency. Its marketplace currently serves 11 cities across six European countries, giving businesses access to a vetted network of service providers.

  • Boost.space

    Participated · Seed · Oct 2025

    Founded in 2017 in Prague, Boost.space tackles the growing problem of scattered corporate data and tool sprawl. Its cloud platform connects more than 2,500 external systems and funnels that data into an "Agentic Database," giving large language models such as ChatGPT and Gemini the structured context needed to execute tasks on behalf of employees. Delivered as a subscription-based no-code/low-code product, the service is already used by over 15,000 teams in 140+ countries, including Seznam.cz, ŠKODA AUTO, Siko and Slevomat. The company employs between 10 and 50 people. Fresh capital will fund U.S. expansion—Boost.space has already opened a San Francisco branch—and accelerate development of Version 5 of the platform. To date, the startup has raised roughly €7 million, with the latest seed extension bringing in €6.17 million.
