When we first set out on this journey to provide delicious food through easily-accessible all-natural umami, we focused on our strengths and stayed in our comfort zone with traditional seafood-based XO sauce.

The Billionaire Sauce is a bold step into the unknown, a product of rigorous testing, culinary imagination and brutally candid feedback. To recreate the distinct umami profile of Billionaire Sauce, we experimented with layering diverse flavors of the land: mushrooms, alliums, peppers, extracts and spices... and we're extremely pleased with the result.

Join us on a culinary revolution as plant-based goes full-blown umami. 

Vegan and Gluten-free.


Dried shiitake, garlic, shallots, ginger, smoked chipotle, chili flakes, tamari, tomato paste, cold-pressed canola oil, and love.


The Gift of Good Taste.

So tasty, must buy!

This sauce is dank AF. An easy topping for me on anything asian and savory. Recommended to my mom and family. Can't wait to try other additions to the family!

XO Sauce

My wife and I grew up in HK and we loved the XO Sauce. It reminded us of home and the great Chinese dishes with XO (e.g., noodles, eggs, seafood, etc.). Definitely a winner!

Packaging and Nutrition/Expiration Info

Love the sauce itself, but the jar packaging was dislodged by the time we opened it. The spoon/glue was also disconnected.

Would like to know the nutrition facts and expiration date as well.

Rainbow of Flavors!

We used the Billionaire Sauce last weekend and it was delicious! We made the pasta dish on the website and it was so unique and scrumptious that I don’t believe that I have ever tasted anything so full of umami with a rainbow of flavors! Thank you for making this and you have a long term customer!!
