I had an excellent session with Guillame. His experience as both a strategist and an operator were on full display. His advice wasn't just some high-level theory; it was practical and actionable. He didn't just tell me what I wanted to hear; he told me what I needed to hear, and that's the mark of a truly great mentor.

My session with Guillaume was amazing! He is a very kind mentor with a lot of empathy. He shared so many insights on the business models and distilled complex information into simple structures. He is also a talented conversationalist and a charismatic speaker. I highly recommend having a session with Guillaume.

Pratik

Guillaume is very knowledgeable. He has fresh, relevant information about AI and what is happening in Venture. His advice to me and my friends was very valuable. Highly recommended for AI technology founders to talk to him.

Expertise

  • Advice on funding

    I've raised capital, I've helped others do it, and i'm now an investor myself. I can help you: - define your fundraise strategy (convertible notes vs. equity rounds, who to approach first etc.) - Build your pitch deck & practice pitching - Understand & negotiate VC term sheets - Manage your cap table - Intro to my VC & angel network - Build your data room Separately, I can support with M&A advisory

  • Go to market strategy

    I can support with growth, G2M & scaling strategy. Through my work in Venture building & accelerators, I have built 6 early-stage start-ups & secured CVC backing for some of them. If I was to sum up my super-power, it is around venture building & scaling knowledge, which I've done plenty of. Hurdles which founders face from inception until Series A I have likely been exposed to one way or another through venture builds. Happy to brainstorm & help solve your problems

    I run an angel syndicate composed of members & alumni of the founders forum. I'm happy to make introductions to other angels, family offices & VC funds in my network where relevant.

  • Consulting

    I advise several start-ups, mostly with fundraising, growth strategy and general coaching. Some of them look for short term advisory on specific asks, others I build long term partnerships with. My sector experience is varied & high-level as opposed to narrow and specialised.
