Vertical AI · Pre-Seed

The Operating System
for the Trades.

Vertical AI for the German skilled-trades industry.

Built by tradespeople, for tradespeople — in an active service business.

Pre-Seed/€400K/Stealth Mode/May 2026
01Why Now

Three forces compel the German trades to digitize — now.

01 — Regulation

E-Invoice mandate.

Since 01/2025, all B2B businesses in Germany must be able to receive electronic invoices. From 2027, sending them becomes mandatory.

02 — Economy

Bureaucracy is exploding.

74% of skilled-trade businesses report that paperwork burden has increased in the last 5 years. At the same time, Germany lacks 250,000+ skilled workers.

ZDH survey, 10,000+ businesses

03 — Technology

The market is waking up.

ServiceTitan IPO December 2024: $9B market cap, 9.8× ARR. Hero (DACH) raised €40M Series B in 2024 (Eight Roads Ventures). The market is validated.

02The Problem

33% of personnel costs go to administration instead of value creation.

Office : Field1 : 2Staff-to-technician ratio in HVAC service. Bitkom 2025: 33% admin time in cleaning trades.
Paper mail77%Of trade businesses still send paper mail. Bitkom Trades Study 2025.
Too busy72%Of trade businesses say they are "too busy" to digitize. Bitkom Trades Study 2025.
“We know the pain because we lived it. In our own HVAC business, we spent years fighting Taifun — the industry-standard software, functional but stuck in the ’90s.”
— Maximilian Wittoesch, Founder
03The Solution

One platform. From lead to maintenance.

01 — Web App

Hub for office & owner.

CRM, quotes, orders, dispatch, e-invoicing, documentation. One interface instead of five tools.

02 — Mobile App

Tool for technicians.

Job acceptance, time tracking, materials, photo docs, signature, offline sync. Usable with work gloves.

03 — AI Features

Live today, agents on the roadmap.

Today: voice agent (inbound call intake), OCR for incoming invoices, voice-to-doc on mobile, receipt scanner. Q3: master-data matching + on-site companion agent.

04How It Works

06Competitive Positioning

We come from the trades. They come from the office.

  1. 01

    Founder from an active HVAC service business

    Not a tech office.

  2. 02

    HVAC + Electrical beachhead → multi-trade ready

    The ServiceTitan playbook: depth before breadth.

  3. 03

    All interfaces out of the box

    DATEV · IDS-Connect (wholesale) · ZUGFeRD & XRechnung (German e-invoicing).

  4. 04

    Hero tested — did not meet our requirements

    Founder tested the largest competitor in his own business. Complex workflows + interface gaps.

  5. 05

    Iteration in days, not weeks

    The founder is the lead user, every day.

07Why We Win

Three reasons we win.

01 — Founder-Market-Fit

Built by tradespeople, for tradespeople.

Constructed in an actively running HVAC business — we solve problems we live every day. Not a tech-bro tool designed at a desk.

02 — Operations Depth

From inquiry to installed equipment, in one system.

Inquiry → Quote → Order → Field visit → Invoice → Maintenance → Contract → Equipment. Competitors cover slices. We cover the whole operating system — exactly the data layer real agents will need.

03 — Field-First UX

Usable with dirty hands.

The mobile app is not an add-on, it's the primary access point for technicians. 80% of daily actions work with three thumb-taps or voice.
