Climate Week NYC is one of the world’s leading global climate gatherings and it’s just around the corner!
But this one feels a bit different. In past years, we came together with a sense of optimism. This year, we come with urgency.
Washington’s retreat from climate programs and the venture market’s pullback from climate tech have sent shockwaves through the ecosystem. Startups are navigating rougher waters. And yet, the need for breakthrough solutions has never been greater.
At SOSV and across our startup development programs – IndieBio and HAX – we’re not slowing down in our mission to fund deep tech founders intent on making a profound impact on planetary health.
This Climate Week NYC, we’re proud to host and participate in a series of events that spotlight the radical science, deep tech solutions, and collaborations building a stronger foundation for a future economy. Here’s where you can join us:
