The first truly great agent
Give your business agents that work around the clock.
Custom Agents is a platform for creating autonomous digital workers. Each agent gets its own email address, a reasoning engine powered by Claude, a built-in CRM, and configurable autonomy — from drafting replies for your approval to handling entire conversations independently. No engineering required.
The problem every business shares
Customer emails pile up. Contact forms go unanswered for hours — sometimes days. After-hours leads disappear. The people who could respond are already stretched thin managing existing clients.
The typical solution is hiring: an offshore virtual assistant with weeks of onboarding, inconsistent quality, and high annual turnover. Or you try a chatbot that can only follow scripts and frustrates customers more than it helps.
Machines can write replies now — that part is solved. What hasn't been solved is giving an agent its own inbox, its own identity, and a way to act on behalf of your business without an engineer wiring it all together. That's what Custom Agents does.
Read more about the problem we solve →What each agent includes
Every agent you create is a fully equipped digital worker. There's no assembly required — you configure it once and it starts working immediately.
A dedicated email address
Each agent owns a real email address — like support@yourdomain.com. It receives, classifies, and responds to emails autonomously. You can use your own domain or ours.
A reasoning engine powered by Claude
Not a template engine. Each agent uses Anthropic's Claude for reasoning, classification, tool use, web search, and multi-turn conversation. It understands context, follows instructions, and knows when to escalate.
Learn about the reasoning engine →A built-in CRM
Every contact, conversation, and data point is automatically captured. No manual entry. The CRM builds itself from your agent's interactions.
Learn about the CRM →Configurable autonomy
Start in draft mode where the agent writes responses but waits for your approval. Move to auto-respond when you're confident. Scale to full autonomy. You control the dial.
Learn about autonomy modes →Integrates with your tech stack
Connect Google Calendar, Shopify, Stripe, HubSpot, Calendly, and more with one-click OAuth. Your agent can check orders, create events, and pull data from the tools your business already uses.
Browse integrations →Scheduled tasks and follow-ups
Agents can schedule follow-up emails, set reminders, and run automated sequences on a timeline you define. No cron jobs or Zapier required.
Learn about scheduled tasks →Built for specific industries

Agents vs. virtual assistants
The average offshore virtual assistant works 8 hours a day, takes weeks to train, and has a 30-50% chance of leaving within a year. An agent works around the clock, trains in minutes, and never quits.
