Antoine Nussenbaum

Who they are

Antoine Nussenbaum is a Partner at Felix Capital — a founding team member of the firm who previously built NT Valley, a verticalized software company for kindergartens and nurseries management.

Person

Possibly — Antoine joined Felix Capital around 2015 as a founding team member, when the firm was being established from scratch. Before that he was an M&A investment banker at ABN AMRO and worked at Atlas Global — a classic banking-to-venture arc that is common among European fund builders. Earlier he founded NT Valley, a verticalized software company for kindergartens and nurseries management, which means he has operator instincts sitting underneath the investor role. He now sits on the boards of TravelPerk, Papier, Lick, Ukio, Hungry Panda, Unmind, Manual, and Pure Pet Food — a portfolio that clusters around digital lifestyle, health, and consumer brands. He teaches Venture Capital as a visiting professor at both the University Paris Dauphine and ESCP European Business School, and has spoken at Slush. On LinkedIn he posts actively on European tech, digital health, future of work, and portfolio company milestones — practical deal-announcement content, not thought-leadership abstractions. The through-line: a founder-turned-banker-turned-VC who stayed in London and built a consumer-and-lifestyle franchise from day one of the firm.

Company

Felix Capital is a London-based venture capital firm focused on technology and creativity-driven companies in the digital lifestyle sector, managing over $1.2 billion in assets under management across a portfolio of approximately 50 companies. Most recently, Felix co-invested in Noah's $22 million seed funding round in June 2025, and backed Origin by participating in its $21 million Series A as the company emerged from stealth — both deals signal continued activity in the health and benefits space. On the portfolio side, TravelPerk strengthened its leadership team with the appointment of Nikita Miller as Chief Product Officer and the promotion of Robin Smith to Chief Technology Officer.

Market

Felix Capital operates in the European venture capital market, backing consumer and lifestyle-oriented technology companies — a segment that includes consumer brands, digital health, travel, and future-of-work tools. The firm competes with other growth-stage European funds for deals in this cohort, where portfolio companies like TravelPerk face well-funded rivals in the business travel space. Geopolitical and regulatory pressures are increasingly shaping cross-border deal-making and financial crime risk, dynamics that affect both Felix's portfolio companies and the broader European VC landscape.

Network

Antoine's visible network runs through his board seats — most recently he has been publicly engaged with Alex Hersham, co-founder of Zencargo, through the Termeer Fellowship. His portfolio connections include Papier (10-year anniversary engagement) and Unmind, where he is active on digital health and future-of-work themes. No edges data is available to surface additional named colleagues.

How they likely show up

  • Founding team member at Felix Capital with a long tenure → likely thinks in fund cycles and multi-year portfolio arcs, not deal-by-deal sprints.
  • Board seats across eight named companies (TravelPerk, Papier, Lick, Ukio, Hungry Panda, Unmind, Manual, Pure Pet Food) → comfortable running parallel tracks and managing at the governance layer rather than going deep operationally on any single company.
  • Founded NT Valley (kindergarten software) before going into VC → brings operator context to board conversations; not a purely financial buyer.
  • Active LinkedIn poster on European tech, digital health, and portfolio milestones → comfortable being publicly visible and uses the platform for deal signalling and portfolio amplification, not just personal brand.
  • Teaches Venture Capital at two universities (Paris Dauphine and ESCP) → synthesizes and structures his thinking for others; likely responds well to structured, well-reasoned framing.
  • Prior career as an M&A investment banker at ABN AMRO → expects financial rigour and is comfortable with deal structure; will pressure-test numbers.

Conversation tips

  • → Reference a specific portfolio company by name — he has eight board seats and will engage more readily if you've done the work to know which one is relevant to the conversation.
  • → If you're a founder, lead with the operator angle — he built NT Valley himself, so he'll read quickly whether you've actually run something.
  • → His LinkedIn posts are practical and deal-focused, not philosophical — match that register rather than opening with big-picture industry theorising.
  • → He teaches VC at two universities, so he's good at explaining the framework behind a decision; ask him to walk through his thesis rather than just his conclusion.
  • → TravelPerk is a marquee board seat and visibly active in the news — it's a safe and substantive entry point if you want to talk portfolio.

Toolbox

Openers

  • Open on the Noah $22 million seed co-investment in June 2025 — it's his most recent announced deal and signals where Felix is placing bets in health/benefits right now.
  • Mention NT Valley — he founded a verticalized software company for kindergartens before going into VC, which is an unusual origin story for a London-based consumer fund partner and is worth unpacking.
  • Reference Papier's 10-year anniversary, which he was publicly engaged with — it's a long-held board seat and a visible point of pride in the portfolio.

Discovery questions

  1. You've been on the Unmind board through the digital health wave and now backed Origin in global benefits — how has your thesis on workplace health evolved across those two bets?
  2. You founded NT Valley before going into VC — how much does that operator experience actually change the board conversations you have with consumer founders today?
  3. Felix has built a digital lifestyle franchise from the ground up to over $1.2 billion under management — what does the firm deliberately avoid that most generalist European funds chase?

Avoid

Don't open with generic questions about the European VC market or macro fundraising conditions — he posts on those themes constantly and will expect you to have a specific angle, not a warm-up question.
