Internship - Junior Venture Analyst

About Marble Marble is a climate tech venture studio. We partner with scientists, engineers, and operators to create companies solving hard climate problems in the world's largest industries. Our first 15 companies are building transformative products across energy, industry, agriculture, and climate resilience. 100% have been successful in raising follow-on to date. We are looking to partner with exceptional individuals to create our next venture. About The Role We are hiring a Junior Venture Analyst intern to join the Marble team and support the market and commercial exploration of key opportunity areas in climate tech. You will work directly with Partners, senior team members, and brilliant founders on a mission to turn the tide on the climate crisis. This role offers a unique opportunity to work with some of the brightest and most mission driven individuals you’ll meet! You will be immersed into the worlds of climate and deep tech venture creation. Expect direct exposure to the many aspects of running a climate tech studio: developing new opportunity theses, supporting founders on strategy and fundraising, running customer reserach, and forming a view on which companies are worth building. This internship is a great fit for a student with a passion for climate tech and venture, with prior exposure in fast-paced environment where they had to own work, navigate ambiguity, and help shape key decisions (e.g. startups, scaleups, VC, corporate dev, consulting, etc.) Location: HQ in Paris, Station F Language: English fluency required. French fluency preferred. Period: 6-month internship starting as soon as possible Responsibilities Founder & company-building support. You'll partner with our Founders in Residence as they turn a technical idea into a real business. That starts with validating their assumptions through market research — forecasts, policy drivers, competition maps, key insights — and goes further into helping them shape business-model options, go-to-market and expansion strategy, roadmap, and fundraising plans. This is effectively strategic consulting: you have a direct say in how an innovation becomes a company, and you diligence each opportunity with full objectivity — do you genuinely believe this will be a fund-returner for Marble? Opportunity & thesis research. You'll work alongside the venture team as they develop new theses and decide where Marble should build next. Your job is to bring the business lens to that work — sizing markets, mapping the competitive landscape and market structure, identifying the real gaps, and pressure-testing whether an opportunity is genuinely venture-scale. You are the commercial and investor eye in the room. Fundraising Operations. Support Partners on fundraising for our second startup studio vintage, as well as potential new vehicles. This includes: investor research (e.g. HNWIs, Family Offices, Fund of Fund, other LPs), data room material preparation, CRM updates, meeting scheduling and follow-ups, etc. Customer development. You'll help run our structured outreach to connect with leading experts and gather insight through interviews, and you'll build out the customer pipeline as we push to "sell" the vision as far as it will go. Portfolio & studio support. On an ad-hoc basis you'll support portfolio companies after spin-out, with, for instance, their first external fundraise post-Marble. You will also contribute to the studio operations that shape how Marble builds going forward, by notably drafting guides and templates used by founders regarding their commercial and financial deliverables while in program. Across all of them, you'll turn your work into clear deliverables — memos, decks, and spreadsheet models (including light financial modeling such as cap tables and projections
