Here's what just happened
Austin and Kat, the Seattle-based CBD brand that built its business on kitchen-batch sourcing stories, just launched a full functional mushroom line, three whole-mushroom powders and two concentrated liquid extracts for dogs. The company is making everything at its NASC-certified Seattle facility (they call it the Makery) using organic, whole-mushroom ingredients from M2 Ingredients, a Southern California grower that cultivates and processes everything in the United States. Suggested retail is $29.95 across the line, and the products are available now through the company's existing distribution partners, including Pet Food Experts, Southeast Pet, Independent Pet Supply, IPS South, and Sunburst Pet Supply.
Why this is actually a big deal
This is a brand extension play disguised as a product launch. Austin and Kat started in 2014 with hemp chews Kat Donatello made in her kitchen for her own dogs, and the company built its CBD line by controlling every step, sourcing, formulation, batch testing, handcrafting, and betting retailers would pay for that story. Now they are running the exact same playbook in mushrooms, a category where ingredient quality varies even more wildly than CBD and most shoppers have no idea what to look for. The bet: retailers will stock a wellness category from the same brand without cannibalizing the first, and customers who trust Austin and Kat's CBD will consider mushrooms.
The timing matters. Functional mushrooms are moving from human wellness into pet, but the category is still dominated by imported mushroom biomass of uncertain origin. Austin and Kat is positioning U.S.-grown, whole-mushroom sourcing as the differentiator, the same way they did with CBD. The difference: mushrooms dodge CBD's regulatory friction entirely. No state-by-state compliance headaches, no payment processor drama, no vet hesitation. Same $29.95 price point, none of the legal overhead.
Founder Kat Donatello said it plainly in the announcement: "Mushrooms are where my obsession with sourcing really shows up. The species matters, the parts of the mushroom matters, and how it is grown and extracted matters even more. We were not willing to put our name on a mushroom product until we could stand behind every step of it."
What this means for the shelf
For the store owner: You get a wellness category with known-brand pull, but you are also teaching customers what turkey tail and lion's mane actually do. Austin and Kat's CBD customers already trust the brand's sourcing story, so the cross-shop potential is real, but the education burden shifts entirely to you. If your team can't explain why whole mushrooms matter or what beta-glucans are, the SKUs sit. The upside: mushrooms let you capture wellness spend without the compliance friction CBD still carries.
For the buyer: This tests whether your CBD customers will cross-shop into mushrooms or if you are just splitting the same wellness budget across more SKUs. The line gives you two format options, powders for the meal-topper crowd, extracts for the liquid-supplement preference, which either simplifies assortment planning or adds confusion depending on how Austin and Kat merchandises it in your market. Watch the sell-through on the single-species powders (Turkey Tail, Lion's Mane) versus the blends (7 Mighty Mushrooms, 6 Mighty Mushrooms). That ratio tells you whether your customers want targeted benefits or just "mushrooms are good."
For the brand/DTC operator: Austin and Kat is showing how an established brand leverages trust to enter adjacent categories faster than a standalone mushroom launch would. They are not inventing a new sourcing story, they are extending the one they already built. If you run a CBD or omega brand with real traction in specialty, this is the model: find a wellness category where ingredient quality varies widely, lock down a transparent supply chain, and let your existing retail relationships do the heavy lifting. The risk: you are asking retailers to give you more shelf space in a store where every linear foot is already spoken for.
Mushroom supplements let retailers capture wellness spend without CBD's regulatory overhead, but only if the team can actually explain what reishi does.
How we're thinking about it
This is a smart play if Austin and Kat can pull it off, and a cautionary tale if they can't. The brand extension logic is sound: they have distribution, they have trust, and mushrooms are a cleaner regulatory path than CBD. But the execution risk is real. Retailers are not mushroom educators by default, and customers walking into an independent pet store still need to learn what functional mushrooms are or why they would pay $29.95 for a powder.
The format split, powders and extracts, is either brilliant or a mistake, and we will not know which until we see how Austin and Kat merchandises it. If the extracts are positioned as a premium tier for customers who want faster absorption, that is a margin win. If they are just "the liquid version" sitting next to the powder with no clear benefit story, you have two SKUs fighting for the same buyer.
What we like: Austin and Kat is not trying to out-innovate the category. They are just applying the same sourcing rigor that worked in CBD to a category where most brands are still importing mystery biomass from overseas. That is a story a retailer can actually tell. What we are watching: whether CBD customers cross-shop or whether this just fragments the wellness aisle.

What to do about it
-
If you already stock Austin and Kat's CBD line... give the mushroom powders a trial run near your existing wellness set. Track whether the same customers are picking up mushrooms, or if you are pulling in a new buyer. That tells you whether this is category expansion or budget cannibalization.
-
If you are evaluating mushroom brands for the first time... ask every rep the same three questions Austin and Kat is answering: Where are the mushrooms grown? Are you using whole mushrooms or mycelium on grain? What part of the mushroom is in the product? Most reps will not have clean answers. The ones who do earn the shelf space.
-
If you run a wellness-forward store... train your team on the functional mushroom basics before the SKUs hit the floor. The source says the powders are formulated to support immune balance, digestive wellness, and everyday vitality; the Lion's Mane Extract supports cognitive function and healthy nerve signaling; and the 6 Mighty Mushrooms blend supports daily immune and digestive function. Keep it simple. The customer who asks "what do mushrooms do?" should get a 20-second answer, not a lecture.
-
If you are a brand operator watching this launch... study how Austin and Kat is leveraging its existing distribution network to enter a new category without starting from zero. They are not cold-calling new accounts, they are asking current buyers to expand the Austin and Kat footprint. That is the brand extension advantage, and it only works if you have already earned the trust.
-
If you are a buyer at a regional chain... watch the single-species SKUs versus the blends. If Turkey Tail and Lion's Mane move faster than 7 Mighty Mushrooms, your customers want targeted benefits and you should stock accordingly. If the blend wins, simplify the assortment and focus on the multi-species products.
The Bottom Line
Austin and Kat is betting mushrooms can carry margin without CBD's regulatory friction. The test: can one brand own two wellness categories, or does the second one just split the budget?
