Founded by former Meta PyTorch and Google Vertex AI engineers, the company powers production AI workloads for companies like Uber, DoorDash, Notion, and Cursor, and is a Series C company valued at $4 billion.
Best For: GTM operators comfortable selling deeply technical infrastructure directly to ML engineers and founders, not just business buyers.
Mercor connects vetted domain experts with the frontier AI labs training the next generation of models, paying out more than $4 million a day to professionals who evaluate and generate training data on its platform. Its Enterprise arm extends the same infrastructure to Fortune 500 companies, capturing institutional expertise and turning it into deployable AI agents. Mercor is a profitable, $10 billion Series C company co-founded by three Thiel Fellows.
Best For: Fast-moving hunters who want to own a full-cycle enterprise sales motion inside one of the fastest-scaling AI-data companies in the market.
Cohere builds security-first foundation models and enterprise AI products designed to run across any cloud, private cloud, or on-premises environment. Co-founded by Aidan Gomez, one of the authors of the original Transformer paper ("Attention Is All You Need"), the company sells directly into regulated, security-sensitive enterprise and public-sector buyers from its Toronto and San Francisco hubs.
Best For: GTM professionals with public-sector or regulated-industry sales experience who want to own territory-level strategy for a security-first AI platform.
ElevenLabs builds AI voice and audio infrastructure spanning speech synthesis, dubbing, transcription, and conversational voice agents, serving millions of users and thousands of businesses from fast-growing startups to Deutsche Telekom and Meta. Co-founded in 2022 by Mati Staniszewski and Piotr Dabkowski, the company has raised $781M and was last valued at $11 billion.
Best For: Builders who want to shape a brand-new partner and customer-marketing motion, or own named strategic accounts, at a company that operates without formal job titles.
Glean runs the Work AI platform that connects enterprise search, an AI assistant, and agentic automation to more than 100 SaaS data sources through a single Enterprise and Personal Knowledge Graph. Founded by ex-Google distinguished engineer Arvind Jain, Glean serves customers across 50+ industries and was named to Fast Company's list of the World's Most Innovative Companies.
Best For: Enterprise SaaS closers who can navigate complex, multi-stakeholder buying committees and want to sell into Fortune 500 accounts adopting agentic AI.
Choosing The Right Role
Not every GTM role at a fast-growing AI startup looks like the title on the job post. Compensation ranges swing widely by stage and equity mix, "remote" can mean anything from fully distributed to a specific coverage territory, and the day-to-day responsibilities of a role often get redefined within the first quarter as the team learns what actually moves revenue. Before applying, it's worth reading the stat strip and team size for each company above as closely as the role card itself — those numbers say more about what the day-to-day will actually look like than the title does.
Pipeline ownership:
the ability to build and manage a pipeline end-to-end, without a fully staffed
RevOps team to lean on.
Technical fluency:
comfort engaging ML engineers, infra leads, and technical founders directly, not
just business buyers.
Data-driven prioritization:
using signal data to decide where to spend time, rather than working accounts in
the order they arrived.
