Serumon

Overview

Serumon runs the cosmetics plant. Its agents control raw-material dosing and order of addition, hold temperature, shear, vacuum, and homogenisation to build target viscosity and particle size, read shade spectrophotometrically against the standard, govern fill weight across jars, tubes, bottles, and compacts, and drive the robots that cap, decorate, and case-pack. A make-and-fill digital twin simulates the batch before a single kilogram of pigment is committed.

The category has been solved in pieces for thirty years — a vessel controller here, a homogeniser there, a spectrophotometer on a bench, an inspection camera at the end of the line, an MES sitting above all of it recording what already went wrong. Nobody had closed the loop from perception to vessel-and-line control. Serumon does, and every batch it runs makes the next one more accurate.

Léa and Matteo applied in early 2025, three weeks after their first pilot line went autonomous at a contract manufacturer outside Lyon. The plant had cut shade holds to near zero and clawed back overfill giveaway that had been quietly written off for years. They were approved in two days and onto the Industrial & Physical AI track the same week.

What Stackpass unlocked

• 01

  Compute for a vision-heavy product

  High-speed shade, fill-level, and defect vision is expensive to train and expensive to serve. The maximum cloud and GPU allocation covered both through the first two plants.

• 02

  Simulation and edge tooling

  Perks across simulation, robotics, and edge-inference platforms let a nine-person team run a digital twin that would normally need a much larger budget.

• 03

  Regulated-manufacturing mentors

  Sessions with operators who had shipped GMP-grade systems shaped the audit and validation posture before the first enterprise buyer asked for it.

• 04

  A round built on introductions

  Curated introductions to funds who invest in physical AI, plus round-preparation support, turned a first pilot into a seed round in one quarter.

Founders

• Léa Vasseur

  Co-founder & Chief Executive Officer

  Formulation chemist by training. Spent nine years leading compounding and shade development for a European contract manufacturer, where she signed off on the batch records that Serumon now writes automatically.

• Matteo Brunelli

  Co-founder & Chief Technology Officer

  Robotics and controls engineer. Built vision-guided filling and packaging cells for high-speed personal-care lines before turning the same edge stack toward autonomous compounding and rheology control.
