Guillaume Moubeche: lemlist Founder, Email, LinkedIn and Bio (2026)

Guillaume Moubeche at a glance

Guillaume Moubeche’s email address: how to reach him

The one address Moubeche has published himself is guillaume@lempire.co: he lists it as the owner contact of his BILLIONS podcast feed (BILLIONS) (checked November 8, 2026). It is a lempire address in a podcast directory field, not an invitation to pitch, so keep messages short. His family office, Clifton, lists team@clifton.partners (Clifton).

lemlist staff mostly use just their first name: {first}@lemlist.com or {first}@lempire.co, such as maya@lemlist.com for a fictional Maya Chen. Newer staff, and people who share a first name, often get the last initial: maya.c@. Moubeche’s LinkedIn accounts have been removed more than once, so his profile address changes; his own domain, guillaumemoubeche.com, redirects to his current profile (checked November 8, 2026). lemlist.com’s DMARC policy is quarantine, so mail that fakes a lemlist.com sender should land in spam (DNS checked November 8, 2026).

Before emailing any pattern-based address, run it through a verifier: a bounce hurts deliverability for every later send. All lemlist patterns and official inboxes are on the lemlist email format page.

Career timeline

How Guillaume Moubeche built lemlist

Moubeche trained as a chemical engineer, worked at P&G and Hermès, and then took a master’s in marketing. He ran a lead-generation agency, LeadGuru, at the Station F incubator in Paris, and there teamed up with two engineers, François and Vianney Lecroart, who were leaving a product of their own (Failory). They launched lemlist in 2018, after he sold his LeadGuru shares (Failory); he says he put in his last $1,000 (Growth Unhinged).

lemlist never raised a funding round. In October 2021 the founders sold part of the company to a fund at a $150 million valuation (CFNews) (Growth Unhinged); “we each took a $10 million home,” he said (SaaS Club). The Lecroart brothers left soon after, “very unplanned”, he said (SaaS Club).

He later handed day-to-day management to Charles Tenot, who had joined as CFO and became CEO (ColdIQ). Moubeche remains lempire’s controlling shareholder and now invests in pre-IPO tech companies through Clifton, which he founded with Diane-Rose Dupré, a former UBS banker (Clifton); CFNews covered its move into secondaries in September 2026 (CFNews).

Guillaume Moubeche’s net worth

No rich list has published an estimate. The figures on record are his own: lemlist was valued at $150 million in the 2021 sale (Growth Unhinged), he says each founder took about $10 million home from it (SaaS Club), and he remains the controlling shareholder (Clifton) of a company that reports over $60 million of ARR (lemlist). We don’t estimate a figure.
