Negotiation (Optional): 4 Key Terms

By Devon Coombs, CPA, MBA · Teaching Professor of Finance, Santa Clara University · Reviewed August 2026

Term-sheet negotiation vocabulary describes how founders and investors reach agreement on the economic and control provisions of a venture financing. Concepts such as the term sheet itself, a founder's BATNA, anchoring in an opening offer, and the distinction between clean and dirty terms determine how a deal is proposed, evaluated, and closed. Founders who understand this language are generally better positioned to compare offers on substance rather than headline valuation, a theme developed in the optional negotiation appendix of the free Entrepreneurial Finance course.

These terms are taught in Appendix: Term-Sheet Negotiation & Deal Dynamics of the free Entrepreneurial Finance course; the full course glossary collects every chapter in one place.

Anchoring: The negotiation bias of fixating on one salient number, usually the headline pre-money valuation, while conceding the terms (participation, board, pool) that quietly matter more.
BATNA: Best alternative to a negotiated agreement, the walk-away option that sets a party's true leverage. In a raise, a second live term sheet is a founder's BATNA.
Clean vs. dirty terms: A "clean" term sheet uses market-standard, founder-friendly terms (1x non-participating preference, broad-based antidilution); a "dirty" one stacks investor-favorable terms that can outweigh a higher headline valuation at exit.
Term sheet: A mostly non-binding summary of a financing's key economics and control terms, negotiated before the binding definitive documents are drafted.
