Stackhaus builds AI automations, ERP systems, websites and Roblox games, and runs the digital marketing that brings customers in. One Finnish studio with fixed prices and no hand-offs.
From automating your daily admin to launching a game on Roblox, everything is built by the same team, so it all works together.
Hand repetitive work to AI agents that read emails, process invoices, answer customers and update your systems around the clock. We connect AI to the tools you already use, with a person approving anything that matters.
A complete business platform instead of ten spreadsheets: customers, quotes, orders, invoicing, stock, payroll and email, all on one database. We run our own multi-tenant ERP, so you get a system that already works on day one and is shaped to how you actually operate.
Fast, mobile-first, SEO-ready websites and web shops built to turn visitors into customers.
Complete Roblox experiences in Luau, from core gameplay to monetization and live updates.

Anything repetitive and rules-based: sorting email, reading invoices, answering common customer questions, moving data between apps, and producing reports. We start with one process that saves the most time.
We use business-grade AI services with clear data policies, keep access to the minimum needed, and design workflows with GDPR in mind. Sensitive actions always need a human to approve them.
A website or a single automation usually takes 1–3 weeks. ERP systems and Roblox games depend on scope, and you'll get a timeline with the quote.
