Breaking the Series B Trap: Scaling Deep-Tech Battery Innovation in India
Terrarium in partnership with TDK Ventures is hosting an exclusive session : Breaking the Series B Trap in Battery-Tech
This is a tricky one, isn’t it? Which is exactly why we’re holding space for an open, off-the-record dialogue between founders and investors across different stages.
The idea is to understand, as an ecosystem, how we can back deep-tech battery innovations that can redefine what sustainable energy storage looks like.
No panels. No pitches.
Just a room of people who are building and backing real breakthroughs, and who know how hard it is to get from lab to scale.
We’re bringing together founders building battery startups in India, the kind that demands time, capital, and deep technical conviction: from next-gen chemistries and circular manufacturing to second-life and solid-state systems. Alongside them, investors who’ve backed some of the most promising material science and energy-tech companies or are actively looking to.
Because scaling climate solutions means scaling material innovation, and battery-tech sits right at that intersection.
The format is simple: a few provocation points by Ravi Jain, Investment Director at TDK Ventures to kick things off, followed by guided dialogue, where the hard questions can be asked and answered.
If you’re deep in the tech and you’re asking how we fund and scale what actually matters, this is your room.
