In 2017, they appeared on Season 03 of Shark Tank Australia, seeking $500,000 for 10% of equity, valuing the company at $10 million. Sharks found Winston and Selvam’s pitch impressive, and they were interested in Sleeping Duck. Both Steve Baxter and Andrew Banks made offers, but the owners did not accept them. After rounds of negotiation, Andrew made a counteroffer, which was also declined; thus, Sleeping Duck had to leave without a deal.

Sleeping Duck had massive business growth, although they could not win a deal. Sleeping Duck is an award-winning mattress company that performs well in the market. You can place orders through the company website. Shipping is available across Australia and the United Kingdom.
