## About

Based in Berlin, Germany, Phase0 GmbH was founded in 2020 by Matthäus Kerres and Ferdinand Witt-Dörring, and operates a browser-based AVA, HOAI and site-management software platform for small and mid-sized architecture and engineering firms. As of September 2026, the company is led by its CEO, Matthäus Kerres. On 14 September 2026, Phase0 closed a EUR 2.6 million Seed extension equity round led by Realyze Ventures, with participation from existing investors LocalGlobe and Atlantic Labs, to fund the expansion of its AI agents for administrative work in architecture and engineering firms. Phase0 delivers one browser-based platform built around three subscription modules for small and mid-sized architecture and engineering practices. Its AVA software covers cost estimation and calculation, bills of quantities, tendering, awarding, invoice verification, change-order management and GAEB import and export. Its HOAI software produces fee proposals, fee and partial invoices and e-invoices, with time tracking and project controlling. Its Bauleitung (site management) software provides site documentation, defect ticketing and an AI site diary that builds reports from WhatsApp photos and voice messages. An AI Bill of Quantities generates specifications in chat from project data and checks long texts against VOB and DIN requirements. The software requires no installation and runs on all devices and operating systems. Phase0 earns revenue from per-user software subscriptions billed monthly or annually. Published pricing is EUR 80 per user per month for one module, EUR 120 for two modules and EUR 160 for all three, with a 20 percent annual-billing discount. Paid add-ons comprise a time-tracking-only licence at EUR 16 per user per month and an LV price database at EUR 20 per office per month. A 14-day free trial precedes any paid subscription. Phase0 plans to use its September 2026 EUR 2.6 million Seed extension round to expand its AI agents, so they automate further administrative tasks around costs, billing, documentation and project management in architecture and engineering firms. Lead investor Realyze Ventures will additionally support Phase0 in widening market access through its construction and real-estate network.
