The operating system for AI workers

Give your business AI employees that work around the clock.

Custom Agents is a platform for creating autonomous AI workers. Each agent gets its own email address, an AI brain 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 at $1,200 to $1,800 per month, with weeks of onboarding, inconsistent quality, and 30-50% annual turnover. Or you try a chatbot that can only follow scripts and frustrates customers more than it helps.

AI can write replies now — that part is solved. What hasn't been solved is giving an AI 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.

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.

An AI brain 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.

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.

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.

100+ integrations

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.

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.

How the economics work

The average offshore virtual assistant costs $1,200 to $1,800 per month. They work 8 hours a day, take weeks to train, and have a 30-50% chance of leaving within a year. Custom Agents costs $50 per month, works 24/7, trains in minutes, and never quits.
