Who is the Biggest Shark in the Tank?
To answer this question, I needed to find data. Luckily, I found an awesome site called Sharkalytics that tracks Shark Tank data from the episodes. After I found the data, I started to think about what components and metrics would be needed in order to quantify how much of a "shark" the investors really are. I started to think about what really appears to make an investor seem shrewd. First, a "shark" would pursue more equity than the entrepreneur offered. Second, a "shark" would pursue a deal with the intention of purchasing the company for less than asking price. Finally, a "shark" would be willing and aggressive in regards to making multiple deals. Using these components, the Shark Score was created.
The Shark Score is a metric used to quantify how much of a "shark" the investor truly is. It is composed of three factors:
Deal Equity to Pitch Equity ratio: This identifies how much equity was obtained by the investor relative to what the entrepreneur offered.
Deal Valuation to Pitch Valuation ratio: This ratio identifies how much the investor valued the business relative to what the entrepreneur valued it.
Total Deals Made: This is simply the count of total deals made.
Finally, the Shark Score is computed as (Deal Equity to Pitch Equity ratio/Deal Valuation to Pitch Valuation ratio)*Total Deals Made
The scores are then bound from 0-10 using a correction factor based off of the maximum Shark Score. The top Shark Score receives a 10.
Now that I had the Shark Score worked out, I started to visualize the data using Tableau. I saw a cool article by Andy Kriebel on creating DNA charts using Tableau, and I thought this would be perfect for visualizing the Shark Score components. Using Andy's tutorial, it was fairly easy to create the charts I needed.
It's also notable that for all of his insistence on being a shark, Kevin O'Leary takes the least equity of any investor and values the companies close to average. Kevin also makes the least amount of deals, so he actually has the lowest Shark Score of any investor. As Kevin would say, "The numbers don't lie", and in this case, he's not as much of a "shark" as he claims.
