Keep building with the Starter plan

Mar 16, 2026Ornella Altunyan4 min

Starter is a new Braintrust plan with no platform fee, designed for teams scaling beyond the Free plan. You only pay for usage based on data associated with processed data and scores, making it easier to keep building as your usage grows.

Starter is built for continued momentum. Pro is built for teams that need advanced features and more predictable workflows.

Pro includes advanced capabilities like environments, custom charts, Topics, more flexible permission roles, additional human review configurations, and 30 day data retention. If you need predictable spend or advanced features, Pro is the right fit.

If you need enterprise features like SSO, compliance (SOC2, HIPAA, custom DPA), priority support, or a shared Slack channel, contact us to discuss an Enterprise plan.

What happens to existing plans

Nothing changes if you're currently on a Free or Pro plan. Your plan, features, and pricing stay the same unless you choose to switch.

  • Existing Free plan orgs can continue as-is. If you'd like access to on-demand usage or advanced features, you can switch to Starter or Pro from Settings > Billing.
  • Existing Pro plan orgs keep their current pricing and features. No action required.
  • Switching plans is straightforward. Go to Settings > Billing to upgrade from Starter to Pro, or downgrade from Pro to Starter. For Enterprise, contact us.

When you upgrade from Starter to Pro, you get immediate access to all Pro features. You'll be charged a prorated amount for the remainder of the current month, and then the full $249/mo platform fee starting the next billing cycle.

FAQ

Do I need to do anything to keep using Braintrust?

No action is required. If you're on an existing Free or Pro plan, you'll stay on that plan unless you choose to switch.

When should I choose Starter?

Choose Starter if you're scaling beyond the Free plan and want to keep building with a $0 platform fee, while paying for usage as you scale.

When should I upgrade to Pro?

Upgrade to Pro when you need advanced features like environments, custom charts, and Topics, or when you want higher included usage and more predictable workflows.

What happens if my usage grows on Starter?

Starter uses on-demand usage pricing. As usage increases, charges reflect that growth rather than requiring a platform fee.

Does this change anything for existing Free/Pro customers?

Not unless you change plans. Existing orgs remain on their current plans and are not impacted by these changes.

What about Enterprise plans?

Enterprise plans include SSO, compliance features (SOC2, HIPAA, custom DPA), priority support, a shared Slack channel, and custom usage limits. Contact us to learn more.
