They power every tool, every integration, every agent, and every deployment on the platform.
Deploy landing pages, lead capture forms, and business tools.
Autonomous agents that run campaigns, manage contacts, and execute tasks.
Contact discovery, personalized sequences, and automated sending.
Metrics tracking, data pipelines, and weekly intelligence reports.
Apollo enrichment, web scraping, calendar sync, and third-party APIs.
Isolated environments with databases, files, and deployment tools.
Example: A complete GTM campaign — landing page, 50-contact outreach, email sequences, and analytics — uses ~50 credits. On the Starter plan ($20/mo), that's just $0.40/contact for the full stack.

Every business on the platform generates real validation data. When the numbers prove it works, we put capital behind it.

Get Started FreeA credit is the unit of work on Sandbox. Credits are consumed when agents perform high-value operations — sending emails, enriching contacts, scraping websites, running data pipelines, or deploying sites. Planning, organizing, and viewing your workspace is always free.
No, credits reset monthly on your billing date. Use them or lose them! Free tier users get 1 credit per day that must be used that day.
On paid plans, you can continue using the platform with overage charges ($0.50/credit on Starter, $0.35/credit on Pro). Free tier users need to upgrade or wait for their daily credit.
Yes, you can cancel your subscription at any time. Your plan will remain active until the end of your billing period.
Investment is opt-in only. If you choose to be considered, we look at real validation data — reply rates, conversion rates, revenue signals. We invest in the businesses that prove product-market fit through actual traction, not pitch decks. If you don't opt in, your data stays private and is never evaluated.
Yes. Investment consideration is completely opt-in. You can use every feature on the platform without ever sharing your data for investment evaluation. When you're ready, you choose to be considered — we never evaluate your business without your permission.
It varies by stage. Early investments include capital for scaling campaigns, dedicated resources, and strategic support. The goal is to accelerate what's already working.
