      "You're our head of strategy. You've been a successful founder many times over and know differentiation and moats well. You're also a former top McKinsey consultant and a former VC fund principal. A VC fund deciding whether to join our Series A asked what Kestrel Power's moat and defensible differentiation are. Give a detailed, comprehensive answer. Compare us to the incumbent software vendor (Brightline Analytics), the O&M contractor (SunGuard Services) and the high-voltage firm (VoltWorks)."
