OneQrew and HalloPetra Announce Strategic Partnership –

Boosting Growth for AI-Powered Office Assistance in the Skilled Trades

> Petra: The Virtual AI Office Professional with Exponential Growth Potential
> Groundbreaking Solution to Combat Skilled Labor Shortages in the Trades
> Now Available to 45,000 Trade Customers and Beyond
> First Integration with Leading Trade ERP System TAIFUN+

Freiburg/Berlin, September 3, 2025 – OneQrew GmbH, a leading provider of digital solutions for the skilled trades, and HalloPetra GmbH, developer of the AI-powered virtual office assistant “Petra,” have entered into a strategic partnership. The goal is to significantly expand the market segment for intelligent process automation in the skilled trades through “Agentic AI,” i.e., autonomously service-oriented AI, and to unlock new revenue potential.

Petra manages incoming calls for trade businesses, organizes callbacks, sorts inquiries by customer and trade type, and prioritizes them for faster response. The assistant works around the clock—reliable, scalable, customer-focused, and independent of location or business hours.

As part of the partnership, HalloPetra will also be offered in combination with OneQrew’s software subscriptions via the new MyOneQrew platform. Both companies are investing in powerful integrations with OneQrew’s ERP products to enable deeper connectivity and higher levels of automation. This will expand Petra’s capabilities, making her even more flexible and versatile.

Benno Quade, Co-CEO, OneQrew

“Petra addresses one of the biggest bottlenecks in the trades—the shortage of skilled workers, not just in the field but also in the office. The solution is highly scalable, immediately deployable, and delivers clear efficiency gains for our customers. For OneQrew, it opens another way to meet our customers’ needs in the best possible way.”

Fabian Fricke, Owner, Tischlerei Fricke, Sibbesse:

“Petra is like a colleague who never gets sick and always stays calm—we know that every customer is heard, no matter how hectic things get in the shop or on-site. Since Petra was connected to our OneQrew ERP, every piece of information goes straight into the central system. That means we can respond precisely to every request without losing time.”

Jonas Südfels, Co-Founder, HalloPetra:

“With OneQrew as our partner, we can massively accelerate Petra’s scaling and expand our market presence. At the same time, we’re broadening the scope of use by integrating Petra into OneQrew’s trade software—a clear win for both companies and the entire market.”

Petra—the virtual office assistant from HalloPetra and OneQrew—is now available not only to OneQrew’s 45,000 trade customers, but to companies across all industries and sectors.
