AI-native application · Vertaya

Lucas AI, the AI ERP for construction.
AI at the heart of the work, not in a tab.

The tradesperson speaks, Lucas acts. Quotes, invoicing, cash flow, HR, scheduling, equipment, public tenders — driven by voice or text, by an AI that understands construction vocabulary. Here the intelligence is not an assistant bolted onto a piece of software: it is the starting point of the work.

What Lucas AI does

The whole of the trade,
driven by voice.

One person to talk to, more than 200 trade tools behind them. The tradesperson dictates, Lucas genuinely executes: it creates, invoices, follows up, schedules, orders. And it understands construction vocabulary — “crawl space 80 mm”, “progress statement”, “AHAT”, “handover file”.

Why “native”

The AI is not bolted on.
It is the starting point.

Most trade software adds an “AI assistant” button next to its screens. The intelligence stays peripheral: it comments, it suggests, but it neverdoes anything and learns nothing from what you correct.

Lucas AI is built the other way round. The AI is the interface: voice and text are the way into the work, the dashboard is only a view of what the AI has already executed. Every trade action goes through it.

It is this architecture — the AI at the heart of the flow, not in a tab — that will make it possible, tomorrow, to capture trade judgement. A peripheral AI captures nothing; a native AI sees everything go through.

This is Vertaya's conviction, made tangible in a real application.

What “native” means
01
The AI is the interface
Voice and text first; the dashboard is only a reflection, not the way in.
02
It actually executes
More than 200 trade tools behind the conversation — not just answers.
03
It sees everything go through
Every action passes through it: that is the raw material for capturing trade judgement.
Voice quoting

From voice to PDF,
in 30 seconds.

The tradesperson dictates the job from the van. Lucas extracts the line items, calculates the VAT, prepares the PDF and sends it — without a single line typed at a keyboard. The AI does the work, not the tradesperson filling in a form.

Factur-X & eIDAS signature

Invoicing compliant with the reform and qualified electronic signature — quotes, contracts, handover reports.

Frequently asked questions

Construction trades and building firms — from the sole tradesperson to a small business running several teams. Insulation, structural work, fit-out, HVAC, electrical: Lucas understands the language of the trade (“crawl space 80 mm”, “progress statement”, “handover file”) and adapts to your work, not the other way round.

It drives the whole of the trade by voice or text: voice quotes turned into a PDF, invoicing and progress billing, site and project tracking, HR and contracts, scheduling, cash flow, equipment, public tenders and energy-certificate files. More than 200 trade tools genuinely execute the actions — Lucas doesn't just answer, it creates, invoices, follows up and schedules.

In most software the AI is a button sitting next to the screens: it comments but executes nothing. Lucas AI is built the other way round — the AI is the interface. Voice and text are the way into the work; the dashboard is only a reflection of what the AI has already done. This is what Vertaya calls an AI-native application.

On sovereign infrastructure hosted in Europe, on a PostgreSQL database isolated per company and compliant with GDPR. Your quotes, clients and sites do not go off to feed a third-party service, and the AI engine stays independent of any single provider — the model is interchangeable, not locked in.
