AI automation agency in New York that builds systems under your team.
Simple4u builds and runs custom AI automation for small and mid-size businesses in New York: marketing reporting, booking and payments, customer service, and the integrations between your tools. Built by the six people who operate the same systems every day for a Brooklyn spa and a yacht charter.
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
Four places where a small business loses hours every week.
Marketing reporting and alerts
Google Analytics, Search Console and ad accounts read by an agent that posts weekly verdicts to Telegram: what moved, why, what to do. Your marketer stops pulling reports and starts deciding.
Booking and payments
Your website, your booking system and your payment processor wired into one flow. We have done it with Adyen and a spa PMS, and with LatePoint and Square for a charter business, including server-side purchase tracking.
Customer service on the site
An AI concierge trained on your own pages and policies, answering at 3 a.m. and pointing anything it cannot handle to your staff. Around forty guest questions a day at World Spa since June 2026.
Integrations and internal tools
Gmail, Drive, Calendar, Slack, Jira, your CRM, connected through OAuth to one agent with memory. Plus the small internal dashboards that replace a spreadsheet nobody trusts.
Systems you can go and look at.
Numbers below come from the clients’ own analytics. We show them because we operate them.
AI concierge, World Spa, Brooklyn
Live since June 2026 on a 50,000 sq ft wellness destination. Answers from the spa’s own pages and policies, and sends bookings and complaints to the spa’s phone line.

People who searched for a spa, not for World Spa (“spa brooklyn”, “hammam nyc”, “onsen nyc”), and landed on the site. SEO and AI-search work plus a marketing analyst agent, alongside the spa’s own marketer. For scale: about 130,000 visits a month reach the site from all channels, most of them from the spa’s own marketing and ads.

A full site rebuild since December 2025, a rebuilt Google Business Profile and server-side purchase tracking for a Brooklyn charter. It ranks #1–3 in Google Maps for “boat rental brooklyn” within 2 km of the marina.

A call with the founder
What runs your business today, where the hours go, what you already tried. No deck.
A one-page plan, free
What to automate first, what it connects to, what it will cost. Yours to keep whether or not you hire us.
First build, fixed price
Source code in your repository, data in your accounts, documentation, thirty days of fixes.
We run it, or you do
The marketing retainer keeps it running for $2,300 a month, with changes and new features billed hourly, or your team takes it over with our docs. Nothing is locked in either way.
The system goes under your team, not on top of it.
A lot of AI automation is sold as headcount reduction. We build the other way round: the marketer gets an analyst with every number, the owner gets a project manager who never drops a task, the website gets a service desk that answers at night. The people stay. The floor under them gets stronger.
No lock-in: the code we write for you and your data stay yours, and another team can take them over. We also publish our earlier agent platform (SAE4U Agent, Apache 2) for anyone to read and self-host.
AI automation in New York, answered plainly.
A build is counted in hours at $120 to $250 by role and signed as a fixed price after the free one-page plan, before any work starts; an AI front desk is $3,000 to set up. A full system takes four to six weeks; a site on its own takes less. Running it afterwards is the marketing retainer at $2,300 a month, or your own team.
We are in Brooklyn and meet New York clients in person. The systems themselves are built and operated remotely, so clients outside the city work with us the same way, over Telegram or Slack and a weekly call.
One person on your side who owns the decision, and access to the tools the system will read: your analytics, booking software, email or calendar. Data stays in your accounts. We connect through the vendors' own OAuth, never by asking for passwords.
Claude and OpenAI models for most work, local models when data cannot leave your premises. We also publish SHAITS, a trust standard for self-hosted AI; our own self-audit against it is next.
It is built not to. Every example on this page added a system next to a person, not instead of one: the marketer got an analyst, the owner got a project manager, the front desk got a night-shift concierge. The system sits under your people and they keep the keys.
Or just talk to us
Simple4u is a six-person team: founder in Brooklyn, project manager, designer and three engineers in Kyiv. We have been embedded with World Spa since 2023 and run our own company on the same kind of systems we sell.
