Partech, the global investment platform for technological innovation, has announced that it has promoted five investors who will strengthen the theme and who have been chosen for their ability to have an independent vision, their ability to manage long-term partnerships and the necessary ambition. These promotions reflect Partech’s belief in the need to invest in people who bring the new perspectives and focus necessary to support Europe’s most ambitious entrepreneurs, as demonstrated by the figures for the first half of 2025, which saw six new companies added to the portfolio and three exits.
Partech’s seed strategy is based on supporting, empowering and assisting visionary founders from the outset and accompanying them as they grow. Recently, the team announced two new investments in ai|coustics and Yampa, as well as significant follow-on rounds in Quibim (50 million dollars in Series A), Metycle (€14.1 million in Series A), Epsor (€16 million in Series C), Merama (US$215 million raised), Pennylane (€75 million in Series D), Vsora (€40 million) and Orus (€25 million in Series B).
Alison Imbert promoted to partner. Alison joined Partech in 2018. Since then, she has invested in around 20 start-ups. Before Partech, she worked for four years as a senior consultant at Roland Berger in Paris, where she worked on private equity and data science projects. Alison holds a master’s degree in Engineering from Ecole Centrale Paris and studied data science at Ecole Polytechnique.
Romain Lavault, general partner, comments in a statement: “Alison has consistently demonstrated a keen instinct for identifying and supporting exceptional founders in the early stages. She has played a key role in supporting companies such as Pennylane, Joko, Epsor, Metycle, Orus and CO2 AI. She is highly regarded by our founders and has established herself as a pillar of our seed strategy as we expand our operations in Europe.
Moritz Steinbrecher promoted to principal. Moritz joined Partech in 2021, following his passion for supporting early-stage founders and his belief in the European technology sector. With the seed team, he has contributed to and led investments in development and infrastructure, deep tech and SaaS. His venture capital career began at b2venture (formerly btov) and continued at Delivery Hero’s venture division. He holds degrees in Economics and Data Analysis.
Boris Golden, general partner, says: “Moritz has been promoted to principal, not only in recognition of his outstanding contributions to Partech’s seed strategy, but also because he is now taking on an increasingly important role, also leading our Berlin office. Moritz has a keen eye for early-stage opportunities in the field of development tools, deep tech and the DACH ecosystem (Germany, Austria, Switzerland, ed.) in particular. He has played a key role in researching, evaluating and supporting our investments in many companies, such as Enter, FlexAI, Lun and Pydantic.
Ariadne Lemieux-Cumberlege promoted to senior associate. Ariadne joined Partech in 2023, with previous experience in sales pps & strategy at Pennylane, a seed portfolio company. Prior to that, she took her first steps in the tech ecosystem at Société Generale Ventures, where she focused on fintech. Ariadne holds a bachelor’s degree in Politics and Economics from UCL in London and a master’s degree in Finance from Sciences Po Paris.
Romain Lavault, general partner, says: “Ariadne has demonstrated a remarkable ability to identify and collaborate with founders from the earliest stages, often before the product was ready and generating revenue. She has already been a key partner in our investments in ai|coustics, Metycle, Presti, Yampa and many others, and we are excited to see her continue to grow in this new role.”
Partech’s venture team closed an excellent first half of 2025, marked by two exits: SideCare (with a strategic investment by Malakoff Humanis) and Memfault (acquired by Nordic Semiconductor). The team also concluded four new deals (RockFi, Shakers, Mercanis and Cloudquery), as well as significant follow-on rounds, including Shippeo’s $30 million fundraising and Rinse’s $32 million Series D.
Simone Riva promoted to partner. Simone joined Partech in 2021. Prior to Partech, he worked at H14, one of Italy’s leading family offices, where he led the direct investment strategy from Series B to pre-IPO. Previously, he worked for four years at Bain & Co, specialising in healthcare and private equity. Simone holds a master’s degree in management from ESCP Europe and another in business economics from the University of Turin.
Philippe Collombel, founding partner and general partner at Partech, said: “Simone has made a key contribution to our venture strategy since joining us in 2021. He played a key role in our investments in Exein, Koro, Shakers, SmartPricing and Retraced. We are delighted to welcome Simone to the partnership: this promotion is a well-deserved recognition of his impact and commitment to Partech’s mission.
Julia Najman promoted to senior associate. Julia joined Partech in 2024. She began her career in infrastructure private equity at Macquarie and EDF before moving into technology investment. She then spent a year in growth equity at Red River West and another at 360 Capital, focusing on pre-seed investments in France. Julia holds a master’s degree in management from HEC Paris.
Reza Malekzadeh, general partner at Partech, comments: “Julia has played a key role in expanding Partech’s sourcing activities and has been instrumental in closing new investments such as Retraced, RockFi and Shakers. She is also a trusted partner for both her colleagues and the management teams of our portfolio companies.”
