Sierra acquires Anon. Sierra built Anon to help enterprise AI agents securely use websites the way people do. That means navigating pages and taking actions like signing in or filling out forms, even when there's no API. Sierra is excited to share that Anon is joining Sierra, bringing its team's expertise and access to its technology to agents that already handle billions of customer interactions each year. Building Anon. Before Anon, I co-founded Spring Labs and spent years working on identity and data security for financial services companies. As AI agents started to emerge in early 2023, I saw a problem that felt familiar. If agents were going to act for people, they'd need a secure way to sign in and take action as them. Its first implementation of this was an AI personal assistant. It got a lot of early use, but it showed Sierra the bigger opportunity was building infrastructure for the wave of AI agents to come. Sierra thought of it as "Plaid for AI agents." Building it took Sierra deep into browser use. Most of what people do online happens behind a login, in interfaces built for people versus for software, and with no API. Sierra built the stack to help agents work in those environments. That included authentication and credential handling, browser infrastructure, an agent harness, and an SDK developers could embed in their products. Sierra raised more than $13M and shipped a product used by hundreds of customers, from AI startups to publicly traded companies. Over the past year, Sierra also built and deployed agents for its largest enterprise customers across banking, healthcare, and enterprise software (including some that are Sierra customers, too!). Reliability is the hardest problem in browser use, so this became its central focus. Sierra made sure its agents could handle sensitive data and multi-factor authentication, run for hours on a single task, and recover when something broke. Over time, Sierra completed hundreds of thousands of complex tasks in production. This obsession with reliability shaped both its technology and its understanding of what enterprises need from agents at scale. Why Sierra. I first met Clay through a mutual investor and Sierra saw the fit right away. Sierra has an exceptional team, a clear point of view on where agents are headed, and a relentless focus on producing outcomes for its customers. In a market moving this fast, I haven't seen that combination anywhere else. Sierra were solving related problems for many of the same companies, with the same expectations for security and reliability. And now with Horizon, agents built on Sierra are pursuing longer-running goals, like originating a loan or getting prior authorization for a healthcare procedure. Completing those goals requires working across multiple systems, including services that don't have APIs. Sierra'll help Sierra's agents bridge that gap. When a step requires signing in to a website, navigating a portal, or entering information through a browser, agents will be able to carry more of the work through to completion. The timing is right, too. Better models and harnesses have made browser agents far more reliable, and the best ones now outperform people on many real-world tasks. That makes this the right moment for Sierra to join Sierra. Thank you to the customers who trusted Sierra early, the investors who backed Sierra, and everyone who built Anon with me. I'm also grateful to Bret, Clay and the team for betting on Sierra and Sierra can't wait to contribute to what comes next at Sierra.

Comcast says AI cut customer service contacts 20% as it sheds 30 million interactions. Comcast said artificial intelligence cut its customer service contact rate by 20% this year, as the cable operator lost 144,000 residential broadband customers in the third quarter and moved to eliminate 753 jobs in Pennsylvania and New Jersey. The company has eliminated more than 30 million service interactions so far in 2026 compared with the prior year, executives said on its Oct. 22 earnings call. Comcast is expanding AI across the customer experience through partnerships with two vendors. Cresta provides what Steve Croney, chief operating officer for connectivity and platforms, called an "agentic front end" for assisted channels, managing handoffs between bots and human agents. Sierra will handle bot-to-bot interactions over time. Croney said the tools draw on personalized data models and an offer recommendation engine that let the company vary treatment by transaction type and customer. Comcast Ventures invested in both vendors, participating in Cresta's $125 million Series D and Sierra's $175 million Series C. Comcast said its Net Promoter Score continued to improve but did not disclose the score or the size of the gain. The broadband loss compared with 91,000 a year earlier and exceeded the 116,800 decline analysts surveyed by FactSet had expected. Total revenue fell 6.1% to $29.3 billion, according to TechSpot, while net income rose 3.5% to $3.45 billion. Free cash flow fell 14.8% to $4.21 billion. The domestic wireless business added 368,000 net lines, bringing its total to 10.6 million. About 45% of broadband customers are on Gigabit+ tiers. The layoffs include 634 positions at Comcast's Center City Philadelphia offices, effective Dec. 31, and 119 across nine New Jersey counties, effective in January, according to state notices. The company said it will hire more than 1,100 people for new positions as part of the restructuring, including more than 500 in Philadelphia. Comcast employs about 15,000 people in the region and 180,000 worldwide. Executives said the restructuring will reduce layers of staff and expand the use of AI agents in customer service. The company expects a restructuring charge of about $1 billion in the fourth quarter. "We've embarked on the most significant operating and cost transformation in our company's history," President and co-CEO Michael Cavanaugh said on the call.
