Zerolook, a Zug‑based B2B flight‑shopping API, closed a €1.6 million (US$1.9 million) pre‑seed round on August 11, 2026, led by Playfair with participation from Vento Ventures, TrueSight Ventures and Alpha Venture. The capital will fund the launch of API v1 and expand the Zurich machine‑learning team.
Zerolook announced a €1.6 million (US$1.9 million) pre‑seed financing on August 11, 2026, positioning the startup to address the exploding cost of AI‑driven flight searches. The round was led by London‑based Playfair and included Vento Ventures, TrueSight Ventures, Alpha Venture and a group of angels from technology, travel and financial services.
Deal Terms
The seed round provides Zerolook with the runway to ship its first API version and to double its machine‑learning staff in Zurich. No valuation or revenue multiples were disclosed. The company’s co‑founders, Simone Lini and George Hadjiyiannis, highlighted that the funding will accelerate the rollout of a prediction model that returns itineraries and prices with confidence scores, allowing airlines and travel agencies to answer high‑volume AI queries without incurring prohibitive compute costs.
Market Context
Travel‑search economics have shifted dramatically. Zerolook cites a historic look‑to‑book ratio of 1:50 for human agents, 1:500 for OTAs, over 1:10,000 for metasearch, and now beyond 1:200,000 for AI‑powered tools. At those volumes, traditional GDS or airline‑system fare calculations become uneconomical. By predicting fares instead of recomputing them for every query, Zerolook claims it can unlock traffic that is currently blocked, turning a cost center into a revenue source.
The startup’s leadership brings deep industry pedigree: Lini previously headed Google Travel partnerships and founded Waynaut, while Hadjiyiannis was a VP of product at Kayak and has engineering stints at Google, NVIDIA and eBay. The team has already secured letters of intent with several online travel partners, setting the stage for early pilots once API v1 is live.
Zerolook’s approach targets a niche of B2B travel technology providers that are grappling with the surge in AI‑generated search volume. If the model delivers on its promise, it could reshape pricing infrastructure across airlines, OTAs and metasearch platforms, forcing incumbents to reconsider legacy fare‑calculation pipelines.
Why It Matters
For Zerolook, the seed round validates a market hypothesis that AI‑generated search traffic is a hidden cost burden for airlines and travel agencies. The infusion of capital enables the startup to move from prototype to production, giving it a first‑mover advantage in a space where incumbents such as Amadeus, Sabre and Travelport still rely on compute‑intensive fare‑lookup engines. Early pilots could translate into sticky API contracts, creating a defensible revenue stream before larger players can replicate the prediction model.
Competitors that continue to charge per‑search will face pressure as Zerolook’s API promises to turn unserviceable queries into billable traffic. Airlines and agencies that adopt the solution may see lower operating expenses and higher net revenue retention, forcing legacy vendors to accelerate their own AI‑driven cost‑reduction roadmaps. The deal also signals to other travel‑tech founders that investors are willing to back niche AI‑SaaS solutions that address specific infrastructure inefficiencies.
Key Points
- Zerolook raised €1.6 million (US$1.9 million) in a pre‑seed round led by Playfair.
- The round also included Vento Ventures, TrueSight Ventures, Alpha Venture and several angels.
- Funding will be used to launch API v1 and expand the Zurich machine‑learning team.
- Zerolook’s API predicts itineraries and prices, aiming to reduce the cost of AI‑driven flight searches.
- The company has secured letters of intent with multiple online travel partners for early pilots.
Analysis
The seed financing places Zerolook at the early‑stage end of the valuation spectrum, likely in the low‑double‑digit‑million range given the €1.6 million raise and the absence of disclosed multiples. The deal underscores a broader trend: vertical SaaS firms are leveraging AI to solve deep‑rooted cost inefficiencies in legacy industries. In travel, the look‑to‑book ratio has ballooned to over 1:200,000, turning every search into a potential loss for airlines and agencies that still pay per‑query. By shifting from compute‑heavy fare retrieval to predictive pricing, Zerolook offers a model that can improve gross margins for its B2B customers and open new expansion revenue streams.
For operators, the raise signals that building AI‑enhanced APIs can attract capital even before revenue traction, provided the team has domain expertise and clear cost‑reduction value. Investors see an opportunity to back a differentiated solution that addresses a quantifiable pain point, with the potential for high‑margin recurring revenue once the API is adopted at scale. If Zerolook’s pilots prove the confidence‑scored predictions are accurate, the startup could command premium pricing, drive strong net revenue retention, and set a benchmark for AI‑driven cost‑optimization SaaS in other travel‑related verticals.
