内容总结：

由前Salesforce联席首席执行官布雷特·泰勒创立的AI智能体初创公司Sierra近日获得资本市场高度青睐。这家专注于企业级客服AI智能体开发的企业于本周四宣布完成3.5亿美元新一轮融资，由现有投资方Greenoaks Capital领投。据公司公告显示，此次融资后其估值已达100亿美元。

Sierra成立于2024年初，由泰勒与谷歌资深高管克莱·巴沃尔共同创立。在运营仅18个月内，该公司已成功吸引SoFi、Ramp、Brex等数百家企业客户。截至目前，Sierra融资总额达6.35亿美元，其中包括去年二月由红杉资本和Benchmark领投的1.1亿美元，以及去年十月由Greenoaks主导的1.75亿美元融资，ICONIQ和Thrive Capital等知名机构也参与投资。

值得关注的是，泰勒与巴沃尔在客服技术领域积淀深厚。泰勒不仅曾在Salesforce任职近十年，其创立的Quip于2016年被Salesforce以7.5亿美元收购；巴沃尔则主导过Gmail、Google Drive等谷歌旗舰产品的研发。二人在谷歌共事期间结缘，泰勒更因推动谷歌地图上线而广受赞誉。

与此同时，Sierra宣布启动第二届APX人才培养计划，面向计算机专业毕业生提供智能体工程与产品管理的轮岗机会。泰勒表示该计划将赋予新人"超常规的决策权"，复制其与巴沃尔当年在谷歌获得的创新自由。在当前AI技术重塑就业市场的背景下，此项人才战略显得尤为引人注目。

投资者对Salesforce前联席首席执行官布雷特·泰勒的人工智能代理初创公司Sierra明显持乐观态度。

这家专注于为企业打造客服人工智能代理的公司周四宣布完成3.5亿美元融资。根据公司博客公告，此轮由早期投资方Greenoaks Capital领投，使公司估值达到100亿美元，该消息也证实了Axios周三的早前报道。

Sierra由泰勒和谷歌资深高管克莱·巴弗于2024年初共同创立。公司宣称在运营的18个月内已获得数百家客户，包括SoFi、Ramp和Brex等。

截至目前，Sierra融资总额达6.35亿美元，其中包括去年二月由红杉资本和Benchmark领投的1.1亿美元，以及去年十月由Greenoaks领投的1.75亿美元。其他投资方还包括ICONIQ和Thrive Capital。

据TechCrunch此前报道，泰勒与巴弗在客服技术领域深耕多年。泰勒在Salesforce任职近十年，更早时创立的Quip于2016年夏季被Salesforce以7.5亿美元收购。巴弗则在谷歌管理过Gmail、Google Drive等多款面向用户的产品。

泰勒与巴弗相识于谷歌任职期间——在出任Facebook首席技术官之前，泰勒曾供职谷歌并被公认助力推出了谷歌地图。多年后，在埃隆·马斯克收购推特期间，他还负责监督推特董事会。

本周初，泰勒宣布启动Sierra第二届APX项目。这个面向技术专业应届生的轮岗计划，完全复刻了二十年前助推泰勒与联合创始人克莱·巴弗开启职业征程的谷歌培养模式。

在当前日益严峻的就业市场中，这项招聘计划显得尤为突出。尤其当企业正在评估类似Sierra所售人工智能技术的潜力及其对人力需求的影响时，该计划更具特殊意义。

该项目针对计算机科学毕业生，提供代理工程与产品管理的双重实践机会。泰勒形容这些职位将赋予"超乎想象的责任权限"——类似于他与巴弗当年在谷歌享有的产品构建与发布自由度——应届生首年即需参与多个产品发布项目。

Investors are clearly bullish about former Salesforce co-CEO Bret Taylor’s AI agent startup Sierra.
Sierra, which helps enterprises build customer service AI agents, announced it raised a $350 million funding round on Thursday. The round, led by earlier investor Greenoaks Capital, values the startup at $10 billion, according to a company blog post that confirmed an earlier report from Axios on Wednesday.
Sierra was founded in early 2024 by Taylor and longtime Google alum Clay Bavor. The company claims to have landed hundreds of customers, including SoFi, Ramp, and Brex, among others, in its 18 months of operation.
Sierra has now raised $635 million altogether, including $110 million that closed in February of last year led by Sequoia and Benchmark, and a $175 million round that closed in October of last year led by Greenoaks.
Others of its investors include ICONIQ and Thrive Capital.
As TechCrunch has previously reported, Taylor and Bavor have a long history in customer service tech. Taylor spent nearly a decade at Salesforce and years ago founded Quip, which Salesforce bought for $750 million in the summer of 2016. Bavor managed Gmail and Google Drive at Google, among other consumer-facing products.
Taylor met Bavor while at Google, where he worked before serving as Facebook’s CTO for several years. At Google, Taylor is widely credited with helping to launch Google Maps. Years later, he’d oversee the Twitter board throughout Elon Musk’s takeover of the social media site.

Earlier this week, in fact, Taylor announced that Sierra is launching its second year of its so-called APX program, a rotational opportunity for recent technical graduates that directly mirrors the Google program that launched both Taylor’s and co-founder Clay Bavor’s careers two decades ago.
The hiring announcement stands out in what has become an increasingly tough job market, particularly as companies assess the power of AI technologies like those Sierra is selling and their potential impact on workforce needs.
The program targets computer science graduates and says it offers experience in both agent engineering and product management. Taylor described the roles as providing what he calls “an irresponsible amount of responsibility” — similar to the freedom to build and launch products that he and Bavor had at Google — with new graduates expected to work on multiple product launches during their first year.
