Co-founder & CEO of SeerDesk · Systems developer
01 Introduction
I'm Lenny. I build SeerDesk, a sovereign remote desktop with 30 ms latency, as co-founder and CEO. I'm a systems developer with a background in cybersecurity, and an apprentice engineer at ENSSAT.
02 SeerDesk · Distributed Remote Desktop Solution
ROLE
Co-founder & CEO · Seer SAS 2025 – present

I handle development and the business side, alongside two partners.

OVERVIEW

SeerDesk is a French, sovereign remote desktop solution that feels local: around 30 ms from the remote machine to your screen. It is built for demanding graphics work (engineering firms, CAD/BIM, architecture, 3D, video editing) where lag ruins everything. Instead of giving every employee a costly workstation, a company shares a few powerful machines, installed on its premises or hosted in our European data centers, and its team works on them from any computer, in the office or remotely. Aimed first at small and mid-sized businesses without an IT department, it ships as software plus pre-configured hardware, billed per user per month.
