About
The person behind GTSuite
Giancarlo Thiella
I design and build GTSuite, a metadata-driven platform that turns configuration into complete web applications, with no hand-written code.
GTSoftware isn't a corporation with a call centre and a sales floor. It's one developer who architects, writes, tests and supports every part of what you run. Choose GTSuite and you're not buying a black box: you're working directly with the person who made it.
The road to GTSuite
I've been building business software since the mid-1980s, starting as a consultant for an IBM dealer in Biella, Italy's wool capital, then as head of IT for the G. Schneider textile group and manager of its in-house software company, Systhema. Four decades in, one thing was undeniable: most management software is the same scaffolding (forms, grids, rules, reports, permissions) rebuilt from scratch on every project.
So in 2007 I stopped rebuilding it. With Project Studio Italia I created the first metadata-driven suite, PSSuite, on Oracle: describe the application once, let an engine build it. It matured into A1Suite in Switzerland, gained a SQLite core and a first Node + Angular front end, and in 2023 became GTSuite, the fully web-native heir of everything before it. Today I run GTSoftware from Sardinia: consulting for The Schneider Group, and pouring most of my time into GTSuite and projects like GTR, a district-heating management system.

- 2007Founds Project Studio Italia; builds the first metadata suite, PSSuite, on Oracle.
- 2009Co-founds Alter One in Switzerland; the suite matures into A1Suite.
- 2013–2021Group head of information systems; A1Suite gains a SQLite core and a first Node + Angular front end.
- 2023GTSuite is born, the fully web-native heir of A1Suite.
- 2025Relocates to Sardinia. GTSoftware today: GTSuite plus client work like GTR district heating.
- 2026The Designer becomes GTSL, cross-platform on Windows and Linux. GTSuite ships as a Docker package and reaches its first on-premise customer installations.
Across industries
Over four decades I've delivered systems as lead analyst and database developer and, for several like GTR (and its predecessor BUS, which I built end to end), the client application too.
Wool & textile
My deepest domain, across many projects.
Apparel & garment manufacturing
Order and production management for clothing.
Accounting, finance & factoring
Ledgers, financials and factoring operations.
Utilities
BUS, later reborn as GTR: district heating.
Production & manufacturing
Shop-floor and production control.
Deployed around the world
My textile systems never stayed in Biella. Over the years they've been installed and run across five continents. And many are still online in production today.

Italy · Switzerland · Netherlands
Oceania
Australia · New Zealand

China · Mongolia · Iran
Africa

Americas
USA (factoring) · Argentina (wool & production)
Built through every technology shift
I've adopted (and retired) a lot of stacks. The one lesson that outlived all of them is what GTSuite is built on: keep the business logic in data, not in whatever language is fashionable this decade.
What I stand for
Your data, your rules
Open standards, no proprietary lock-in. You can always take your data and walk away: that's the point.
On-prem or cloud, your choice
Run GTSuite on your own servers or hosted: control without needing an enterprise IT department.
Substance over bloat
No checklist padding. Every capability is there because a real business needed it.
Built to last
Proven open-source foundations: Angular, Ionic, Node.js, MongoDB. Nothing you can't inspect, host or maintain yourself.
Why working with one person is a feature, not a risk
A direct line to the maker
No support tiers, no ticket lottery, no 'let me escalate that.' You talk to the person who can actually change the code.
No telephone game
What you ask for is understood by the one who builds it: nothing lost between sales, product and engineering.
Continuity and accountability
One vision, one hand on the architecture, for the long run. My name is on it.
Focused, not spread thin
GTSuite isn't a side project fighting fifty others for a slot on the roadmap.
No lock-in, no single point of failure
Working with one person raises a fair question: what if I'm not around? The answer is in the foundations. GTSuite runs entirely on open-source platforms used by millions worldwide (Angular, Node.js, MongoDB) and it's thoroughly documented. Nothing is proprietary or hidden: you can host it, audit it, or hand it to any competent team and carry on. You depend on standards, not on me.
