Key takeaways
- About 62% of pitches end in an on-air deal. That's 951 deals from 1,533 pitches.
- Founders give up more than they planned. On average, the final deal took 10.8 percentage points more equity than founders first offered, and deal valuations came in about 37% below the asking valuation.
- Multi-Shark deals are common: 260 deals involved two or more Sharks.
- Royalties and loans are part of the toolkit. 99 deals included a royalty and 55 included a loan or credit line.
- 1,048 companies still had an active website at our last check, and 55 are known to have been acquired.
Deals are as agreed on air. Some change or fall through during due diligence afterward. Valuation-cut figures exclude outliers where the deal valuation was more than three times the ask.
