Justin Doane — Founder, Variant Energy
Former Tesla engineer (4680 Tabless cell manufacturing) and Sila Nanotechnologies lead, now building Variant Energy to deliver the next generation of lab-scale battery prototyping equipment.

In addition to building cutting-edge machinery, Variant Energy is a technical partner for investors and operators making high-stakes decisions in energy storage and advanced manufacturing.

Drawing on first-hand experience building cell prototyping equipment and leading R&D scale-up efforts, we provide targeted consulting support in three high-value areas:

1. Venture Capital Due Diligence

Investors regularly tap us to validate technical claims, assess IP defensibility, and benchmark early-stage companies against industry practice. We help separate engineering reality from pitch-deck optimism, so capital is deployed with confidence.

2. Early-Stage Startup Guidance

We work directly with founders and technical teams to:

  • Define realistic development roadmaps
  • Identify and avoid common battery cell manufacturing pitfalls
  • Prioritize limited resources for maximum technical and commercial impact

3. Expert Interviews for Investment Banks & Networks

Variant Energy frequently engages in one-on-one calls with investment banks, consulting firms, and expert networks seeking direct insight into:

  • Cell prototyping equipment markets
  • Process bottlenecks in lithium-ion R&D
  • The evolving landscape of lab-to-pilot scale transitions for next generation chemistries
