BECOME UNSTOPPABLE

​This is a six-month program co-led by Helena Wasserman and Christine Amour-Levar, designed to equip climate startup founders around the world with the tools, strategy, and investor access they need to succeed.

Together, we're expanding Unstoppable into a truly global initiative—supporting founders who are solving the climate crisis from every corner of the world. Whether you're early-stage or ready to raise, this is where purpose-driven founders come to level up—with clarity, capital, and community.

GET BACKED BY THE RIGHT INVESTORS

3-STEP FRAMEWORK FOR IMPACT & GROWTH  

Step 1: Positioning & Storytelling

We review and refine all your external communications—pitch decks, investor messaging, websites, and brand positioning—for maximum clarity and market relevance. Because the right story, told well, can transform everything.

Step 2: Fundraising & Sales

Backed by a decade of experience - from Techstars and VC Advisory to the Clinton Foundation and Temasek - we’ve developed a proven fundraising methodology. Our alumni typically raise between US$400K and US$1.7M, and last year alone founders raised a collective US$40M. This also includes exclusive access to Investors for Climate city events globally.

Step 3: Accountability & Community

Progress thrives in community. Weekly mentorship calls and peer check-ins keep founders focused, fast-moving, and supported—because you run farther when you’re not running alone.
