About Cartesia

Our mission is to build the next generation of AI: ubiquitous, interactive intelligence that runs wherever you are. Today, not even the best models can continuously process and reason over a year-long stream of audio, video and text—1B text tokens, 10B audio tokens and 1T video tokens—let alone do this on-device.

We're pioneering the model architectures that will make this possible. Our founding team met as PhDs at the Stanford AI Lab, where we invented State Space Models or SSMs, a new primitive for training large-scale foundation models. Our team combines deep expertise in model innovation and systems engineering paired with a design-minded product engineering team to build and ship cutting edge models and experiences.

We're funded by leading investors at Index Ventures and Lightspeed Venture Partners, along with Factory, Conviction, A Star, General Catalyst, SV Angel, Databricks and others. We're fortunate to have the support of many amazing advisors, and 90+ angels across many industries, including the world's foremost experts in AI.

Role Responsibilities

As our Head of Sales, you'll build out our core revenue function. We're looking for someone that can help us scale up our sales org from the ground up - encompassing everything from definining the outbound strategy, team structure, tooling, and GTM playbooks. This is a unique opportunity to step into a key leadership role at a foundational AI startup, and directly shape how we bring our product to market. In this role, you’ll:

• Develop and own the end-to-end sales strategy—from segmentation and outreach to conversion and expansion.

• Hire, mentor, and scale a high-performing sales team (AEs and future SDRs/sales ops/support roles).

• Drive pipeline growth through outbound sales, partnerships, and GTM initiatives.

• Build scalable sales processes, KPIs, and CRM workflows to ensure consistent performance and visibility.

• Cross-Functional Collaboration: Work closely with business operations, engineering, marketing and product to define our approach to GTM

• Accurately forecast pipeline and revenue, and report on key performance metrics to the exec team.

• Identify opportunities for new market penetration, pricing strategy, and channel development.

What we're looking for:

• At least 8 years of SaaS sales experience, with at least 2–3 years in a leadership role.

• Track record of closing enterprise deals in a fast-paced, high-growth environment.

• Proven ability to build and scale a sales function from scratch (preferably in a seed or Series A startup).

• Data-driven approach to pipeline management and performance tracking.

• Excellent storytelling, negotiation, and executive communication skills.

• Deep understanding of sales tooling (e.g., HubSpot, Salesforce, Outreach, Gong).

• Passion for emerging tech and the future of AI-powered communication.

Nice-to-Haves

• Experience selling products in audio or generative AI

• Strong network in SaaS, sales, or growth communities

• Exposure to product-led growth (PLG) or hybrid sales models
