# Katerina Petraki > B2B Marketplace Growth Expert | Prev Alibaba B2B Growth Exec | Advisor & Angel Investor I am a go-to-market operator and investor with a focus on B2B marketplaces and SaaS. I spent my career launching and scaling new ventures at the intersection of digitizing legacy industries, data platforms and network effect businesses. I have done this as an operator, entrepreneur, consultant, and investor. I love startups, marketplaces, and international business dynamics. Most recently, I led the international expansion of alibaba.com, through GTM strategy, partnerships, and investments. During that period, the business grew to over $40 billion of annual GMV, with 4x revenue growth, and transformed from a listings' directory to the largest global B2B trading platform. Previously, I was a strategy consultant with Deloitte and held various leadership roles at Thomson Reuters, after launching my own biodiesel business in Greece. I am an active angel investor and startup mentor (Techstars, Endeavor), and particularly passionate about leveling the playing field for under-represented founders. ‍ Things I can advise on: - B2B marketplace growth - Go-to-market strategy and tactics - Building partnerships & ecosystems - Expanding into new markets, categories, users - Fundraising (Seed to Series A) I love helping founders and can’t wait to connect! ## Offerings - Video call (15 min): $150.00 ## Links - [Expert profile](/KaterinaPetraki) - [Avatar](https://media.intro.co/avatars/9454249eRLu_c3.jpg) - [Marketplace](/marketplace)
