Alexandre Dewez

Who they are

Alexandre Dewez is a Partner at 20VC — he left Eurazeo for Harry Stebbings's London fund and writes the 'Overlooked' Substack, including deal memos on companies like Silvr.

Person

Alexandre came up through an unusual route: HEC Paris (CEMS International Business Master, 2020) with an exchange at Stockholm School of Economics, but before any of that he was doing M&A internships at Mediobanca and a private equity stint at EDF Invest, and — improbably — taught philosophy as an assistant professor while still studying. He joined Idinvest (later absorbed into Eurazeo) in 2019 when it was still operating under that name, becoming a Partner on the venture team and staying through the rebrand and the firm's expansion into a multi-strategy platform. Before finance entirely, he reportedly joined ManoMano as a red-team member at 18 and spent his teens hacking bug bounties — identifying vulnerabilities at Google, Amazon, PayPal, and Netflix — which gives his investor interest in cybersecurity some personal texture. He also spent time at Google Cloud in a Head of Venture Capital & Startup Business Development role, bridging the operator and investor worlds. He co-founded Aleph Studios, described as a venture production company that partners with entrepreneurs to transform ideas into companies. He runs 'Overlooked by Alexandre Dewez' at alexandre.substack.com — deal memos, French tech ecosystem analysis, and an annual 'State of the French Tech Ecosystem' report published each January — and he's spoken at How to Web 2025 on sales team metrics and at First Monday with 20VC. The through-line is a technically grounded operator who went deep into European VC and now sits at the intersection of the French startup world and Harry Stebbings's London platform.

Company

Alexandre joined 20VC after exiting Eurazeo, landing at Harry Stebbings's fund when it was establishing its London presence. His current employer is 20VC — not Eurazeo — so the most relevant recent context is the move itself: leaving one of Europe's largest listed private equity platforms to join a VC fund built around one of tech media's most prominent voices. On the Eurazeo side (his prior firm), 2026 has been active: in June 2026 Eurazeo closed its Private Debt VII fund at €3.9 billion, beating its target; in Q1 2026 it raised €1.1 billion in fundraising; and in early 2026 it launched two new evergreen funds, EPIC and EPSO. These are his former firm's moves, not his current platform's — but they frame the institutional world he just stepped out of.

Market

20VC operates in early-stage venture, competing with a mix of European seed and Series A funds as well as US crossover funds increasingly active in Europe. The broader private equity and venture market that Alexandre has spent his career in faces headwinds from higher interest rates and geopolitical uncertainty, though European mid-market deal flow — his core focus at Eurazeo — has held up, and debt fund expansion has emerged as a growth vector for larger platforms. His move from Eurazeo to 20VC is a bet on brand-driven, founder-centric early-stage VC over diversified institutional private markets.

Network

Alexandre's most visible relationship is with Harry Stebbings, 20VC's founder, whom he joined after leaving Eurazeo — the connection surfaced publicly via Sifted's coverage of his exit. His deal activity at Eurazeo/Idinvest included backing Silvr (documented in his own Substack), and at 20VC he's been involved with Lupin & Holmes (a cybersecurity startup) and XO Market, the latter alongside Picus Capital, Coinbase Ventures, Ventures Together, and Foreword Fund.

How they likely show up

Runs a named Substack ('Overlooked') with published deal memos and an annual French tech report → he processes investment thinking in writing and is comfortable being publicly accountable for his theses.
Background in bug bounty hacking and red-teaming from age 13 → likely brings a threat-modelling, adversarial-thinking lens to diligence — looks for where things break, not just where they compound.
Moved from Eurazeo (large, multi-strategy, listed) to 20VC (smaller, brand-driven, early-stage) → has deliberately traded institutional scale for conviction-based, founder-proximity investing.
Spoke at How to Web 2025 on 'Key Metrics for Efficient Sales Teams' → his public content is operational and specific, not high-altitude VC philosophy; he engages with the mechanics of how startups actually scale.
Co-founded Aleph Studios alongside an active investing career → high agency, runs parallel tracks rather than waiting for a single role to define him.
Medium tenure pattern across roles, with a clear pattern of deepening within a discipline (VC) rather than pivoting across industries → not a generalist drifter; picks a lane and goes deep.

Conversation tips

→ Reference a specific 'Overlooked' piece — the Silvr memo is public — rather than saying you follow his newsletter generically; he'll know immediately whether you've actually read it.
→ Ask about the French tech ecosystem specifically, not 'European tech' as a monolith — his annual State of the French Tech Ecosystem report signals he's thought harder about France than most London-based VCs.
→ His hacking background is not just a fun fact — if you're in cybersecurity or security-adjacent software, it's a genuine shared frame; Lupin & Holmes is a live portfolio signal.
→ Don't treat the Eurazeo→20VC move as a lateral step; ask what drew him to early-stage over the multi-strategy platform model — it's a deliberate bet he's made a case for publicly.
→ He speaks on sales metrics operationally — if you're discussing a company, come with actual numbers rather than narrative; he'll engage more with a conversion rate than a market sizing.

Toolbox

Openers

Open on 'Overlooked' and the Silvr backing memo specifically — he wrote publicly about the investment thesis, which means he's willing to be judged on it; asking what's held up or changed is a direct way in.
Mention co-founding Aleph Studios — a venture production company is an unusual structure and it signals he's thinking about company creation from a different angle than a standard fund; it's worth asking what that looks like in practice.
Reference his How to Web 2025 talk on sales team metrics — it's the most recent named public content and it's operational, not theoretical; it opens a concrete conversation about what efficient GTM actually looks like at the companies he backs.

Discovery questions

Your annual State of the French Tech Ecosystem report comes out each January — what was the single most surprising finding in the most recent edition?
You moved from Eurazeo's multi-strategy platform to 20VC's early-stage focus — what does backing a company at seed look like differently when you're not sitting inside a firm that can follow on through growth and debt?
You backed Lupin & Holmes in cybersecurity and you've been hacking since age 13 — how much does your technical background actually change the diligence conversation with a security founder versus a generalist investor walking in cold?

Avoid

Don't frame European VC as a single undifferentiated market — he's spent years specifically mapping the French ecosystem and will notice immediately if you're treating Paris, Berlin, and London as interchangeable.
