Aisot Technologies closes CHF 2M seed extension to bring AI portfolio intelligence to Swiss and international wealth managers

Aisot Technologies (Zurich) has closed a CHF 2 million / approximately €2.1 million seed extension. The round was backed by existing family offices and angel investors, with Felix Haldner — former Partner at Partners Group and former President of the Swiss Funds & Asset Management Association (SFAMA) — joining as a new investor. Founded in 2021 as an official ETH Zurich spin-off by Stefan Klauser, the company builds AI-driven portfolio intelligence infrastructure for institutional investors: asset managers, family offices, and external and independent asset managers (EAMs and IAMs).

What the platform does

Aisot combines three analytical layers into a single institutionally deployable product. The first is quantitative modelling: machine learning models that generate forward-looking signals across equity markets in Switzerland, the EU, UK, US, and India, at weekly, monthly, quarterly, and yearly horizons. The second is AI-driven news sentiment analysis using time-boxed, fine-tuned large language models — proprietary models trained to use only information available at the time of each forecast, eliminating look-ahead bias and the hallucination risk that generic LLMs introduce in financial forecasting. The third is an agentic layer that converts portfolio data into plain-language insights on performance, risk, and drivers.

The practical argument is efficiency: the company claims savings of up to 90% on manual portfolio management tasks, reduced drawdown through AI-driven risk signals, and a higher Sharpe ratio through systematic signal integration. The platform is designed for clients who want to combine their own views with quantitative AI signals rather than cede decision-making to the model.

Why Haldner's entry matters

Felix Haldner's arrival is the defining signal in this round. Partners Group manages over CHF 150 billion in alternative assets and is one of the most recognised institutional names in the Swiss and European market. As a former Partner there, Haldner brings both credibility with the CIOs and fund administrators Aisot needs to reach and direct experience of how institutional asset management workflows actually function — the insight that shapes which features genuinely reduce friction and which are noise.

"We are convinced that aisot's solutions can generate significant efficiency gains for asset and wealth managers, including in analysis, portfolio management and product development," said Haldner. "Aisot Technologies' models also deliver signals across different investment strategies, with the aim of contributing to return optimization."

What the capital extends toward

The seed extension is a continuity bet, not a pivot. The existing investors expanding their commitment alongside Haldner's entry implies commercial traction rather than a second chance. Aisot's current clients include Swiss family offices, active funds, and EAMs with exposure across equity markets. The capital accelerates the platform's expansion in Switzerland and internationally — the specific challenge being that wealth management client acquisition is a long-cycle, trust-driven process where a former Partners Group Partner in the investor cap table does more than a marketing budget.
