Weflayr, a Paris-based AI startup, has raised $2.5 million in pre-seed funding to develop an intelligent AI inference routing layer. The round was led by 13books Capital, with participation from several other investors.
TL;DR
- Weflayr raises $2.5M to build an AI inference routing layer that optimizes model selection and routing.
- The startup's solution has already demonstrated a 55% reduction in inference costs for a customer.
- The funding will support team expansion and growth in Europe and the U.S.
What happened
Weflayr, a Paris-based AI startup, has closed a $2.5 million pre-seed funding round. The round was led by 13books Capital, with participation from Founders Future, Kima Ventures, Plug and Play, Station F Ventures, General Catalyst scout Roxanne Varza, and a group of angel investors.
The startup aims to give AI companies full control over how they evaluate, select, and route AI models. Weflayr benchmarks models against a customer's own production data, allowing teams to approve trusted models and set routing rules. It matches each request to similar previously benchmarked calls and links inference decisions to costs and margins across customers and features.
Weflayr's first deployment cut inference costs by more than 55% at equivalent quality and delivered 15 percentage points higher relative quality at the same cost compared with a frontier model. The startup was founded by Romain Mazeries, former CEO of Mangopay, and Noé Achache, former Head of AI Engineering at Theodo Data & AI.
Why it matters
Weflayr's solution addresses a critical need in the AI industry: optimizing model selection and routing to reduce costs and improve performance. As the number of AI models grows, companies struggle to manage and route requests efficiently, often relying on a few models without knowing their performance on specific workloads.
The startup's technology has already demonstrated significant cost savings and quality improvements for a customer. This makes Weflayr an attractive investment opportunity for tech investors looking to back innovative AI solutions.
For AI/ML developers and startup founders, Weflayr's solution could streamline the process of model evaluation and routing, allowing them to focus on building and improving their AI applications. The funding will support team expansion and growth across Europe and the U.S., making the solution more accessible to a broader range of customers.

Context
The AI industry is experiencing rapid growth, with hundreds of models competing on quality, speed, and cost. However, most companies rely on only a few models, as traditional AI gateways route requests without knowing how models perform on specific workloads.
Weflayr's solution addresses this challenge by providing an intelligent inference routing layer that optimizes model selection and routing. This not only reduces costs but also improves the overall performance of AI applications.
As AI continues to become more integrated into various industries, the need for efficient and cost-effective AI solutions will only grow. Weflayr's technology has the potential to become a critical infrastructure component for AI companies, making it an exciting development in the AI landscape.
