02. The stack just connected

Six weeks is the ideal lead time, and we can compress to four for a speedy kickoff. Your part is mostly the first week: an intro, a scoping call, and the customer kickoff.

Hi [Name],
Anthropic is partnering with Cerebral Valley to plan, staff, and run internal activations, like hackathons, for a limited group of our fastest-growing Claude Code customers.
We are really excited to see the level of engagement from your teams, and believe we can further accelerate their work with a well-scoped activation focused on outcomes, hands-on content tailored to your team, and having experts in the room from Anthropic to work alongside your builders.
How it works:
- We agree on a date to run the event at your office, and our teams travel to you and handle all logistics
- We co-design the scope and outcomes that need to be achieved
- Cerebral Valley and Anthropic create custom content and workshops, and provide staffing to advise on builds
- Anthropic provides prizes for the winners, like custom trophies, swag, or other internal perks
We have seen this be a great way to meet our teams, open the door for creation and productivity, and bring teams onto the frontier of productivity.
If you are interested, let's discuss over a call so we can dig more into the details and shape the format.
[Your name]
Once they say yes to a date window, submit the request form. Six weeks of lead time is ideal.
FAQ
Which accounts are a good fit?
Customers with Claude live for the people who would attend, a growing base of active users, and an internal champion who can get builders in the room. Strong fits usually have an expansion, renewal, or strategic initiative coming up.
What's NOT the right time to activate?
Wait until there's an internal champion and Claude is connected to their internal tools. Pass if builders can't access Claude yet, or if it's an executive summit or a group under 50.
How many people attend?
50 or more builders. The room is set by the customer's goals: top power users, nominations from each business unit, power users paired with newer users, or an idea-submission process where the best ideas earn a seat.
Does it have to be in person?
In-office is the default and works best. When adoption is brand new, we run a virtual workshop first and then an in-person build. For teams spread across sites, we run a city tour or a cross-office competition. Fully virtual is a fallback, focused on build time rather than sessions.
What do builders work on?
Real problems from their own work. We set a theme with the customer: saving hours, hours saved per token, something their team can use tomorrow, a use case leadership has named, or connecting Claude to their internal stack. Submissions capture hours saved and who benefits, so outcomes are measurable.
What about security, data, and NDAs?
We confirm Anthropic's NDA with the customer covers Cerebral Valley before planning starts. The customer's IT team approves tools and data access ahead of time, and the submission form can live inside their systems if they prefer.
What happens after the event?
A recap for both teams, plus help setting up follow-up sessions with key teams, internal AI user groups led by finalists, and introductions to Anthropic's champion network.
Who is Cerebral Valley?
CV is the world's premier AI ecosystem. We've worked with Anthropic since the launch of Claude 2, producing public events with their team like Built with Opus 4.7, Built with Opus 4.6, Built with Claude: Life Sciences, and the Claude Build Day for startups. See more on our showcase.
