SaaS Platforms
Multi-tenant products built to survive their first thousand customers: authentication, roles and permissions, billing, admin surfaces, audit trails and the dashboards your operators actually live in.
Based in Estonia Working across the EU
Ghostidy is a European product studio. We design and engineer SaaS, fintech and AI platforms — from the first pixel to the infrastructure that keeps them running in production.
Four practices, one team. Strategy, interface and infrastructure stay in the same room — which is why the thing we design is the thing that ships.
Multi-tenant products built to survive their first thousand customers: authentication, roles and permissions, billing, admin surfaces, audit trails and the dashboards your operators actually live in.
Money-adjacent systems where correctness is the feature. Ledgers that reconcile, market and pricing data pipelines, broker and exchange integrations, idempotent execution paths and reporting that stands up to review.
LLM systems with a job to do. Agents and retrieval wired into real data, document and workflow automation, evaluation harnesses — so quality is measured, not assumed, before anything reaches your users.
The studio half. Identity, design tokens and component libraries that carry from a landing page to a dense back-office screen without falling apart — handed over as code, not a folder of mockups.
Short cycles, working software at the end of each one, and a straight answer about what is and isn't done yet.
A week to map the domain, the constraints and the riskiest assumption. You leave with a plan and a number, not a proposal deck.
The unknown part gets built first — the integration, the model, the throughput question — so surprises land in week two, not month four.
Two-week increments against a real environment. Tests, CI and observability go in with the feature, not in a cleanup phase afterwards.
Deploy, monitor, iterate — or hand over a documented system your own team can run. Both endings are fine; we plan for the one you want.
Every change ships behind a check we agreed on in advance. If the number doesn't move, we say so instead of redefining the number.
Demos run against real sources. A screen with invented numbers is a screen that hides the work still left to do.
Code, infrastructure, accounts and documentation are yours from day one — in your repositories, under your keys.
Ghostidy Technologies OÜ is registered in Tallinn and works with clients across the EU and beyond. Contracts, invoicing and data handling follow EU rules — including GDPR — and we're comfortable signing a DPA before the first line of code is written.
We are a software vendor. We build, license and operate software for our clients; we do not take custody of client or end-user funds, and we do not provide investment, brokerage or financial advice.
Send the problem, the deadline and the constraint you're most worried about. You'll get a real answer from an engineer within two business days — including an honest "not us" if that's the right call.
