Lowercarbon Capital's Caie Kelley on the art of the growth round
Key points
Key takeaways from the Fun Raising with VC Sheet interview with Lowercarbon Capital General Partner Caie Kelley, recorded in September ́2026:
Growth-stage sweet spot. Lowercarbon writes $10-30M checks at Series B and Series C, one step past early-stage team-and-dream rounds and one step earlier than $100M+ mega-growth funds, right as commercial proof points and unit economics start to change.
Authenticity over noise. By the time a theme is loud on Twitter or LinkedIn, investors have already underwritten it 12-24 months earlier. Pitch the story that is true to you for a 10-year partnership, not the consensus slot of the week,and remember that you cannot fake science.
Who finds whom. Growth investors get to know founders before a formal raise and watch for that inflection point. Press, writing, conference presence and hyperscaler-style announcements are how they find you; blasting every growth name on a list is not the play.
The readiness test. Growth has no fixed 12-24 month cadence. A founder is ready when they can say: if I put $10 million in, I know how to push that into $100 million of sales, meaning they understand sales, metrics, supply chain and delivery.
Capital allocation. Caie's specialty is non-dilutive financing, grants, management teams at Series B,and how late-stage and infrastructure money think about DevCo, project co and top co. You cannot build a CapEx-intensive business if you do not understand capital allocation.
Why Lowercarbon. The fund has around 120 hardware companies, roughly ́90 of them US-based, investing across energy, advanced manufacturingand resilience. Founders should be able to explain in two sentences whythe world is a better place if their company succeeds.
In the room. Look for equal-caliber talent around the founder, in-person energy,anda vision bigger than the investor's. Growth underwriting asks whether you can hire many operators, not only whether you are the visionary; you never want to dream a dream bigger than your founder.
