Featured Works

Brands, websites and systems we've put into production. Each one has a short film; open it to see more.

  • Branding
  • Website

A new visual identity and a new website for an industrial IoT company, so its technical excellence also shows in how it looks. The first screen lets visitors try the product's assistant, and the page explains the path from sensor to decision in three steps.

  • Industrial AI
  • Digital twin
  • A person approves

A platform that assists, monitors and operates the physical environment remotely, and asks a person before acting. Operators fly through a 3D twin of the place, ask it a question, and approve or reject what it proposes.

IRIS, screen 1IRIS, screen 2IRIS, screen 3
  • 3D showroom
  • Sales tool

A wall of IoT demos laid out like a streaming catalog. Each one builds a store in 3D, puts sensors in it and shows the readings arriving live, so a salesperson can walk a client through it and leave with a proposal.

  • Our own website
  • Three languages

Our site for the Brazilian market, in Portuguese, English and Spanish. A fluid under the pointer changes the photo at the top, the page signs its name as you scroll, and the work scrolls sideways.

  • Clinic system
  • Web + iOS + Android

Scheduling, patients and treatment protocols for an aesthetics clinic, on the web and on the phone. The clinic can ask about its day and get the answer straight from the schedule. The film comes from the tutorials built into the app, with a demo clinic.

  • Experience
  • Event

A noncommercial birthday event. The invitation is a website that opens like a mission: a briefing, squads, a map of the area and a way to say you're coming.

  • Website

The website of a company that builds intelligence for customer conversations. A field of particles opens the page and follows the visitor through every section.

The website of a customer-service platform that puts every channel and an AI assistant in one conversation.

  • Internal platform
  • Company sign-in

The internal platform of Fuse IoT, with team KPIs and operational tracking. It sits behind company sign-in and asks for one more check before it opens protected areas, so that is all we show.

Questions

How can you do it in 15 days?

The scope is fixed: one page with up to 8 sections, built on a brand we finish in the first week. You review twice, on day 7 and day 11, with two rounds of changes each time.

What happens if you're late?

If we go live later than the date in your agreement, even by an hour, your first six months of Care are free. The clock only pauses while we're waiting on you (approvals, photos, logins) or on outside companies like Meta.

Who owns the work?

You do. Your domain, your hosting and your code are in your name from day one, and every design file is yours once the project is paid. If you ever leave us, you take everything with you.

You're in Brazil. How does that work?

We work in English and we're one to two hours ahead of New York, so your workday is our workday. You get a written agreement and invoices in US dollars.

How do I pay?

Half to start, and half when you approve the preview of your site. For the Brandbook, the second half is due when your files are ready. You can pay by bank transfer or card.

What happens after launch?

Nothing you don't choose. If you want us to keep things running, Site Care is $250 a month and AI Care is $450 a month. Both are optional, and you can cancel a monthly plan with 30 days' notice.

What does the AI assistant actually do?

It answers customer questions on your website and WhatsApp, books appointments, and keeps your CRM up to date. It tells people it's an AI assistant, and hands the conversation to your team when someone asks for a person or it isn't sure.
