Term sheet negotiation for a perpetual motion machine startup begins, unusually, with a technical diligence phase that most reasonable investors would classify as a hard stop before any valuation discussion proceeds.
Valuation methodology is difficult to apply conventionally. Standard approaches like discounted cash flow or comparable transaction analysis assume the underlying technology functions as claimed, which in this case would require setting aside the first and second laws of thermodynamics as negotiable terms.
Intellectual property protection presents its own complications. Patent offices in most jurisdictions maintain long-standing policies against granting patents for perpetual motion devices specifically because the underlying physics claims cannot be substantiated, creating an immediate obstacle to the IP-based moat most investors expect.
Milestone-based funding tranches would need to be structured around independently verified energy output measurements, ideally conducted by a third-party physics lab with no financial stake in the outcome and a strong professional incentive to be skeptical.
Liquidation preferences and anti-dilution provisions can be negotiated using standard templates, though sophisticated investors would likely insist on unusually aggressive down-round protection given the technology's fundamental viability risk.
Board composition should include at least one director with a physics background empowered to request independent verification at any point, since founder enthusiasm alone is not sufficient collateral for the capital being deployed.
The realistic outcome for most such term sheets is that they never progress past the technical diligence stage, making this one of the few startup categories where investor skepticism should be treated as a feature of the process rather than an obstacle to overcome.
