Key moments

Find the ideas you need and go straight to the source.

Buying back a declining company

“We bought it back when it was declining precipitously month over month and year over year, and we put a plan together to bring it back to life and grow it through acquisitions.”

Asking for more money

“And we found that their elasticities is material. You can go from $20 to a thousand dollars if you just ask.”

Debt capacity in EBITDA turns

“if a company is doing $4,000,000 with EBITDA, you can probably get loan between two times to four times of the total EBITDA. So 8,000,000 to $12,000,000, you should be able to get that loan for that amount.”

Why equity beats debt

“Because I value the equity far more than I value the debts. It's simple.”

Integrating acquired products

“We buy it, generally it's a product and technology that we're buying in consumers, and then we take them and integrate them into what we already have.”
