About 11x

Most of what GTM teams do all day isn't selling. It's monotonous work like research, list-building, follow-ups, and data entry - things that should never have been a human job in the first place.

11x is building the AI platform for growth by automating the busywork so GTM teams can focus on what they do best: building relationships and closing deals.

Backed by $75M+ from a16z and Benchmark, headquartered in San Francisco, and trusted by leading teams at Checkr, Xerox, Rillet, and much more. We're hiring ambitious people who want to define how the next generation of companies accelerate growth.

About the Role

We’re looking for a Customer Success Manager who is energized by the challenge of scaling new go-to-market motions and driving business impact across a portfolio of high-value customers.

At 11x, we call this a Full Stack CSM—you’ll own the entire customer journey: from onboarding and consulting on use cases, to managing ongoing success and even leading commercial conversations. You won’t just manage accounts—you’ll serve as a strategic advisor to executive stakeholders, deeply embed yourself in customer workflows, and proactively identify opportunities to expand adoption and value. Ideal candidates have hands-on GTM experience—whether through sales, partnerships, business development, or supporting go-to-market tools—and are passionate about building long-term relationships that lead to outsized outcomes.

What You’ll Do

Act as a trusted advisor to C-level and VP stakeholders, aligning our digital workers to their strategic goals and success metrics
Drive adoption, onboarding, and expansion across teams by surfacing new use cases, leading training sessions, and articulating impact
Own and grow your book of business, with a strong focus on renewals, upsell, and product stickiness
Partner cross-functionally with product, engineering, and GTM teams to shape roadmap, resolve friction, and co-create scalable success
Contribute to the broader customer ecosystem—developing playbooks, leading community events, and sharing insights

Requirements

5+ years in a customer-facing role (Customer Success, Account Management, Business Development, etc.)—preferably in SaaS, AI, or GTM tech
A strong understanding of the go-to-market landscape—you’ve either carried a quota, supported sales teams, or helped deploy tools used by GTM orgs
A builder’s mindset: proactive, resourceful, and unafraid to get hands-on in a fast-moving environment
Exceptional communicator and relationship-builder, comfortable engaging senior execs and managing complex projects
You sweat the details, thrive on ownership, and are motivated by helping customers win
Onsite in our London office three days a week—this role is highly collaborative and benefits from being in the room

What We Do

At 11x, we’re not just building tools—we’re redefining how work gets done. We build autonomous digital workers that execute entire go-to-market workflows, end-to-end. Instead of just augmenting tasks with AI, 11x automates the full execution of sales, marketing, and RevOps processes so teams can focus on what they do best: building relationships, closing deals, and driving impact. Our technology integrates across GTM systems, adapts to real business logic, and learns continuously while delivering real outcomes. These aren’t just incremental improvements, they’re game-changing leaps forward in how companies grow.

Everyone here is a builder. You’ll be starting at the ground floor of a rocket ship company with the rare opportunity to leave your mark, shape the culture, and have a seat at the table as we scale. You’ll work side-by-side with a world-class team—people who move fast, think deeply, and care fiercely. The upside? Massive.
