BUSINESS MODEL

Liquid Death

Consumer packaged goods (CPG) — Liquid Death sells canned water and flavored beverages through retail stores, Amazon, and DTC. Revenue comes from wholesale to retailers (7-Eleven, Whole Foods, Target, Walmart) and direct online sales.

The aluminum can format commands a premium over plastic water bottles — a single tallboy typically retails for $1.89 to $2.49, significantly more than a bottle of Dasani. The brand licensing and merchandise arm (selling branded t-shirts, hats, and absurd limited-edition products) adds high-margin revenue.

Advertising partnerships and brand collaborations provide additional income. The company has a subscription model called the "Country Club" for DTC recurring orders.

Sierra

Companies pay Sierra to run their customer service with AI agents instead of hiring rooms full of humans. The agent talks to your customers over chat.

It answers questions. It processes returns.

It updates subscriptions. Here is the clever part.

Sierra charges based on outcomes, not seats. Brands pay when the AI actually resolves a problem, not just for having the software installed.

That pricing is unusual. Most software charges a flat monthly fee no matter what.

Sierra only gets paid when the bot does the job.

HOW THEY STARTED

Liquid Death

Mike Cessario was a creative director who had worked at Netflix and various ad agencies. He noticed something at concerts and punk shows: everyone was drinking water out of plastic bottles, but nobody wanted to be seen doing it because water bottles looked lame next to a can of beer.

The branding insight was almost stupidly simple — put water in a tallboy can with aggressive heavy metal aesthetics, give it the most ridiculous name possible, and market it like an energy drink. He made a Facebook ad in 2018 for a product that didn't exist yet.

The ad went viral with 3 million views. He used the viral proof to raise seed funding and actually make the product.

The first cans shipped in 2019. By 2022, Liquid Death was in 60,000 retail locations and valued at over a billion dollars.

All from water in a can.

Sierra

Bret Taylor had already done the impossible twice. He co-created Google Maps.

He later became co-CEO of Salesforce, chaired Twitter's board during the messy Elon Musk takeover, and became chairman of OpenAI in late 2023. Clay Bavor spent 18 years at Google, most recently running its Labs group.

The two friends left their big jobs in 2023 to build something together. They picked customer service on purpose.

It is the least glamorous corner of software. Their logic was simple.

Companies hate their support costs. Customers hate waiting on hold.

AI that actually resolves problems could fix both sides at once. They launched Sierra in February 2024 with $110 million from Sequoia and Benchmark.

HOW THEY GREW

Liquid Death

Content-first marketing that acts like an entertainment company, not a beverage company. Liquid Death's social media posts, videos, and stunts generate millions of organic views — they've had a witch hex their water, made a real music album from hate comments, and partnered with adult film star Cherie DeVille for a commercial.

Retail distribution expansion from specialty stores to mass market (Walmart, Target, 7-Eleven). The aluminum can itself is a growth strategy — sustainability-minded consumers prefer cans over plastic, giving Liquid Death a values-based selling point beyond the comedy.

Celebrity investors (Tony Hawk, Steve Aoki, Wiz Khalifa) provided credibility and reach. Festival and live event sponsorships position the brand where its core demographic gathers.

The brand's absurdity is the moat — nobody else can copy the tone without looking like they're trying.

Sierra

Sierra went straight for big brands, not tiny startups. SoFi, Ramp, ADT, Sonos and Brex signed up early.

By 2026 it said more than 40% of the Fortune 50 were customers. The trick was trust.

Enterprises are terrified of an AI bot going rogue and insulting a customer. So Sierra built guardrails and let each company control exactly how the agent behaves.

Bret Taylor's contacts did the rest. When the chairman of OpenAI calls a Fortune 500 CEO, they pick up.

Sierra hit $100 million in annual recurring revenue in November 2025, seven quarters after launch, and $150 million by February 2026. In April 2026 it launched Ghostwriter, which builds and deploys a new agent from a plain-English description.

THE HARD PART

Liquid Death

It's still water. The product itself has zero differentiation from any other mountain spring water — the entire value is brand and marketing.

If the comedy stops being funny or the brand loses cultural relevance, there's nothing proprietary underneath. CPG margins are thin and retail shelf space is brutally competitive.

Scaling a premium water brand into mass market means competing on price with Coca-Cola (Dasani) and PepsiCo (Aquafina) who have unlimited distribution muscle. The $1.4 billion valuation requires the company to grow into a full beverage platform, not just a water brand — hence the expansion into iced tea and flavored water.

And there's a real question about whether the ironic marketing can sustain long-term or whether it's a cycle that peaks and fades.

Sierra

Everyone is building AI customer service agents right now. Decagon has raised at a multi-billion valuation.

Salesforce, ServiceNow and Intercom all shipped their own agents. Sierra is not the cheap option.

It sells premium AI to giant companies that move slowly. The bigger risk sits underneath the product.

Sierra does not make its own AI models. It rents them from providers like OpenAI and Anthropic.

If those model makers decide to compete directly, Sierra's edge gets thin fast, and its co-founder chairing one of them only makes that question louder. A $15.8 billion valuation on roughly $150 million in revenue leaves almost no room for a stumble.

THE PRODUCTS

Liquid Death

Mountain Water — still water sourced from the Austrian Alps, sold in 16.9 oz and 19.2 oz tallboy cans. Sparkling Water — same Alpine source, carbonated.

Flavored sparkling water in flavors like Severed Lime, Berry It Alive, and Mango Chainsaw — names that sound like horror movies. Iced tea line expanding beyond water into flavored beverages.

The Country Club subscription for recurring DTC delivery. Merchandise and limited-edition collaborations — from branded caskets to a $50,000 enema kit that sold out.

Every product name and packaging decision is designed to be the opposite of what a water brand would normally do.

Sierra

The core product is the Sierra AI agent. It is a branded customer service bot that companies deploy on their website, app, and phone lines.

It handles the boring stuff. Order tracking.

Refunds. Password resets.

Account changes. Sierra also built its own tools to test and monitor these agents so they do not make things up.

In 2024 the company added a voice version that talks to customers on the phone. In April 2026 it added Ghostwriter, a tool that builds and deploys a new agent from a plain-English description.

The whole pitch is one AI agent that carries your brand's name and never sleeps.

WHO BACKED THEM

Liquid Death

Investors include Science Inc., Velvet Sea Ventures, Live Nation Entertainment, Conviction Partners, and celebrity investors including Tony Hawk, Steve Aoki, and Wiz Khalifa. Series D in 2022 valued the company at $700 million.

By 2023, valuation reached $1.4 billion.

Sierra

Sequoia Capital and Benchmark wrote the first checks at launch in February 2024, $110 million between them. Greenoaks Capital then led both the $175 million round in 2024 and the $350 million round in September 2025.

In May 2026 Tiger Global and Google's GV led a $950 million round at a $15.8 billion valuation, with Benchmark, Sequoia and Greenoaks back in. That takes total funding to about $1.6 billion.

That is partly the product and partly Bret Taylor. Investors bet on founders who have already built billion-dollar things.
