ElevenLabs crossed $500M ARR in April 2026, up from $350M at the end of 2025.

Carles Reina built that revenue org from zero, as the company’s fourth employee and first investor: three years from nothing to past half a billion.

He recently laid out how he did it in a long, direct interview on Harry Stebbings’ 20VC, a set of rules specific enough to copy.

You can’t automate the engine, because the engine is people and some of his rules, like the 20x quota, stay there. What you can encode is the rest, the operational work:

  • who to target

  • which account is worth a call this week

  • which deals are actually real

That is where Claude comes in, with Carles’s rules instead of generic best practices.

By the end you’ll have four Claude agents, each built from one of his rules:

  • Concentrate on one proven ICP before scaling → the Concentration Agent

  • Reach people humanly, not with transactional spray → the Timing Agent

  • Land and expand → the Expansion Agent

  • Public pipeline reviews and conservative forecasting → the Forecast Agent

Your reps keep the room, while your agents take the busywork.

1. Which Sales Rules You Can Actually Hand to Claude

Before you build anything, get honest about what is automatable and what is not. The fastest way to waste a month is to point an agent at work only a person can do.

Some of Carles’s rules are about people. They stay with you:

  • 20x quota is a target you set and hold

  • First contract in two weeks is a hiring and onboarding bar

  • Reps in front of customers is a management choice

  • Selling humanly, not transactionally is a principle, and it's his whole point: the moment outreach feels like AI spray, people ignore it

Build a sell more agent and you build nothing, because selling is the human part.

The other rules are really decision criteria and those can become software:

  • Concentrate on one proven ICP is an instruction about where to point your list

  • Reach people only when it's genuinely relevant, never with transactional volume

  • Land and expand is a repeatable way to read an account and find the next door

  • Conservative, public forecasting is a set of rules for deciding which deals are real

Each of those is a judgment applied over and over against fresh data, which is exactly what an agent is good at.

So the split you are working with:

STAYS HUMAN (guardrails, not agents)
- The 20x quota and the willingness to enforce it
- Selling humanly, not with transactional spray
- Reps in front of customers
- Hiring for hunters
- The room: negotiation, relationship, the final call on a deal

BECOMES AN AGENT (a decision rule applied to fresh data)
- The Concentration Agent  ← "concentrate on one proven ICP"
- The Timing Agent         ← "reach people only when it's relevant"
- The Expansion Agent      ← "land and expand through customer success"
- The Forecast Agent       ← "radically transparent pipeline reviews"

The rest of this guide builds those four agents, and each one takes its name and its job straight from one of Carles’s rules.

The “human rules” don’t disappear, they become the guardrails you write into the agents’ instructions, so everything Claude produces is filtered through the same discipline Carles applies himself.
