Prompt in what you need.
Skip the meetings and the roadmap decks. Describe the outcome you want and get working output back — a live site, a sent campaign, a filled pipeline — not another list of suggestions.
The operating system for serial entrepreneurs
Your business. Run by AI.
Replace the full-time GTM, content, and strategy team with AI agents that cost a fraction, never sleep, and get measurably better every week.
Built for operators running more than one business.
Serial entrepreneurs, consultancies, agencies, and service businesses doing $1M-$10M in revenue use Sandbox.co to run lean without a full in-house team.
One operator, ten-person output.
Agents build sites, run outreach, manage pipelines, and track metrics autonomously — so a single founder can run what used to take a full team.
It compounds every week.
Every decision your agents make is traced, scored, and fed back into the system — so the platform gets sharper the longer you run it.
No engineers required.
Built for non-technical operators. If you can run a business, you can run Sandbox.co — no code, no dashboards to babysit.
