We build AI agents that live in your Telegram, Slack, or website, connected to your tools through OAuth, with memory and a knowledge base that grows every week. They work alongside your team, not instead of it.
Custom work by the team behind our three products, priced after a free one-page plan. A small business usually starts with the AI front desk · all three products
Not chatbots. Persistent AI agents that read your tools in real time, remember every decision and rule, and get smarter every week. Each one is built for one client's stack and operation.
Agent runs in Telegram by default, DMs and group chats with intent-routing. Optional channels: Slack, Discord, web embed, custom.
Every conversation and every correction goes into a knowledge base that belongs to your deployment alone. The agent remembers what it was told last month.
OAuth-connected to your real tools, not screen-scraping. The agent reads what's actually there.
Beyond Q&A: scheduled digests, threshold alerts, draft emails, meeting prep briefs, on-call summaries. Each agent has cron-driven jobs specific to its owner's needs.
SAE4U Agent is the platform we built as a SaaS product and published when we stopped selling it in May 2026: an architecture with empty slots. Anyone can fork it and self-host. When we build for you, we build a system for your business and run it.
The orchestrator, the runtime template, the knowledge base schema, the OAuth wiring, the prompt scaffolding: all there on GitHub. The slots for what your business actually is, your tools, your team's voice, your workflows, your data, come empty. You fill them. You host them. You maintain them.
We build a system for your business. Your tools wired, your voice in the agent’s brief, your workflows automated, your data flowing. You get a Telegram or Slack agent that already knows your operation, and we keep it sharp every week.
First call to a working AI agent in your Telegram or Slack, configured for your operation. A free plan in 48 hours, a fixed-price build in four to six weeks.
What runs your business today, where the hours go, what a Telegram or Slack agent could take off your plate. No deck.
A one-page plan in 48 hours, free either way, yours to keep. If you go ahead, the build is fixed price and takes four to six weeks: OAuth wiring, the agent’s brief tuned to your voice, deployed and tested.
You get documentation and thirty days of fixes. Then the marketing retainer keeps it running for $2,300 a month, with new features billed hourly, or your team takes it over with what we hand you.
Numbers come from the clients' own systems. We show them because we operate them.
A 50,000 sq ft wellness destination, client since 2023. The AI concierge has been live since June 2026, answering about 40 guest questions a day from the spa's own pages and policies, and sending bookings to the spa's phone line. We also built the booking and Adyen payments integration with their spa PMS, TAC.
A Brooklyn yacht charter, client since December 2025. We rebuilt the site from scratch, with booking through their own LatePoint and Square, and added server-side purchase tracking so paid bookings show up in their analytics.
Our project manager bot, marketing bot and memory system run our own company end to end. If we build an agent for your business, it is built by a team that depends on the same kind of system every day.
AI agents become more powerful when paired with operational and analytics service lines.
