What you likely need
Peter is a high-signal serial founder with a landmark $3.2B exit (Segment/Twilio) and is now running two ambitious deep-tech companies — Charm Industrial (carbon removal) and Revoy (electric freight). His primary challenge is scaling capital and talent for hardware-intensive businesses that require patient, mission-aligned investors and operators.
Are these your current priorities?
We will tune and customize your Founder Festival experience to make sure you get invited to the events that would be most valuable to you.
- fundraisingPursue a Series B for Charm Industrial targeting climate-focused institutional LPs (e.g., Breakthrough Energy Ventures, Prelude Ventures) who can write $50M+ checks into proven carbon-removal tech.
- fundraisingRevoy's $500K in funding is extremely thin for a hardware trucking company — prioritize closing a seed or Series A round from mobility-focused investors before scaling fleet operations.
- hiringLeverage your YC S11 alumni network to recruit senior operators (CFO, VP Engineering) for Charm Industrial, where headcount growth is accelerating.
- introsTap former Segment executives and Twilio leadership for warm introductions to enterprise customers who need carbon-removal credits or freight decarbonization solutions.
- fundraisingApply for DOE Loan Programs Office (LPO) financing for Charm Industrial's bio-oil sequestration infrastructure — your proven carbon-removal delivery record is exactly the profile LPO funds.
- tacticalAntipode (autoimmune therapeutics) is a 1-person company alongside two other CEO roles — consider bringing in a co-founder or scientific lead to advance it without diluting your focus on Charm and Revoy.
- positioningYour personal site (rein.pk) and media presence (BBC, VentureBeat, YC) are strong — publish a detailed technical post on Charm's bio-oil sequestration results to attract both talent and mission-aligned investors.
- wellbeingRunning CEO roles at both Charm Industrial and Revoy simultaneously is a significant cognitive load — consider whether one company needs a President or COO to handle day-to-day operations.
