Welcome to AI Drama. A story in two cities, with one villain, a 16-billion-dollar valuation, and one of the biggest conflicts of interest in the entire AI world.

Manila, May 5, 2026. A man named Ivan — a "quality analyst" at one of the world's largest BPO companies — sits across from reporters and says one sentence that should make all of us shiver: "I actually helped improve the work of an AI, and now AI replaced my job."

Same day, 12,000 kilometers away in San Francisco, a press release drops: $950 million fresh funding. Valuation: $16 billion. Investors: Tiger Global, Google Ventures, Sequoia, Benchmark. The company: Sierra. And 99% of humanity has never heard of them.

Even though 40% of every Fortune 50 company runs Sierra agents. One of the three largest banks in the world. Weight Watchers, Cigna, Blue Cross, Rocket Mortgage, Sonos. 95% of US Black Friday shoppers last year had a conversation with a Sierra agent — and never knew it.

📈 The numbers that don't add up

Valuation 9 months ago: $10B → today $16B (+60%)
ARR end of 2024: $25M → February: $100M → today: $150M (6× in 18 months)
Valuation multiple: 105× revenue. SaaS norm is 5-10×. This isn't a valuation anymore — it's an evangelistic belief.

Lead VC Peter Fenton from Benchmark: "Sierra is by all measures the winner in the customer experience category."

🎭 Who is Brett Taylor?

Go check him out — he should be as famous as Sam Altman or Mark Zuckerberg. He's not.

Co-invented Google Maps
CTO at Facebook
Chairman of the board at Twitter — sat at the table during Elon's takeover
Co-CEO at Salesforce next to Mark Benioff. Learned the customer list, the pricing weaknesses, the pain points.
Left Salesforce January 2023 → founded Sierra February 2023

The customer trophy case Sierra poached from Salesforce: Sonos, Casper, Rocket Mortgage. Taylor also poached Eric — the head of Salesforce's Agent Force. The result for Salesforce: support team cut from 9,000 to 5,000 in 18 months. Stock down 30% in 2026 — one of the worst Dow Jones performers.

⚖️ Two chairs, one man

Remember the OpenAI drama? Sam Altman fired, Satya Nadella flying in, mass-resignation threats, the board imploding? In the middle of all that chaos, who got named Chairman of the Board at OpenAI? Brett Taylor.

Now add it up:

Sierra uses OpenAI models → Sierra is a customer of OpenAI
Taylor chairs OpenAI → he sits at both sides of the table
Sierra's $950M round includes Google Ventures — OpenAI's direct competitor
Sierra runs a constellation of 15 frontier models: ChatGPT, Claude, Gemini, Llama, fine-tuned proprietary — they don't care, they're not monogamous

His diplomatic answer for years: "We exist at different layers of the tech stack. I would recuse myself if there was an opportunity for conflict." Sure, Brett. And at Davos in January, he was on CNBC criticizing AI valuations. Four months later he takes $950M at 105× revenue. The man who warned about the bubble is inflating it himself.

🤖 The Sierra Agent OS — what actually happens in 500 ms

When you call a Sierra agent, this happens before you finish your first sentence:

Planner agent receives the customer intent — figures out why you're calling
Executor agents tap into different backends — CRM, payment gateway, inventory, knowledge base. Different models for different jobs.
Validator agent reviews the response against policy rules before it reaches you
Model failover — if OpenAI's API goes down or starts hallucinating, it auto-routes to Anthropic, then to whichever LLM is healthy. Sierra is built assuming every model will fail eventually.

One second into your call, Sierra has already orchestrated 3+ models.

🛒 Who actually runs this

Weight Watchers — 70% of all customer sessions are Sierra. CSAT: 4.6/5 — higher than humans.
Sonos — Sierra handles the hard stuff: full setup wizards, Wi-Fi config, music service integration, end-to-end onboarding
Healthcare, fintech, credit cards, mortgages — the list is long and growing.

These aren't chatbots. They're process machines that take actions.

⚔️ Why AI agents beat humans in this category

Don't get tired — no morning, no evening, no hangover, no sick kid
No bad days. After 3 angry customers a human is done — the agent's consistency is auditable
Speak every language on earth — Zulu, Mandarin, Arabic, Portuguese, all of them
Analyze tone in real time — stressed, frustrated, resigned — and plan the next sentence to de-escalate
Parallel system access — CRM + return policy + manuals + history all in "head" simultaneously
Learn from every conversation. Humans don't — our brains are too small.

🎬 Who watches the watchman?

Two chairs, both empty by midnight. The chairman who left the OpenAI boardroom is the same chairman who signed the $950M term sheet for the company that will be selling you AI agents.

And Mr. Ivan? Ivan and his thousand friends spent years learning headsets, learning manuals, learning customer service. Their jobs are now performed by an AI agent that costs peanuts.

In the AI economy of 2026 and 2027, your company will turn to Sierra. Because it's cheaper. More efficient. Auditable.

And Mr. Brett, with his beautiful conflict-of-interest architecture, is absolutely worth the AI drama.
