TTI Gruppe

What TTI Gruppe does

TTI Gruppe is a Berlin-based, family-owned real estate developer founded in 2011 by brothers Jan and Emil Taschlizki. The company operates across the full real estate lifecycle — acquisition, technical project development, core renovation (Kernsanierung), marketing, rental management, and commercial administration — with a 5-step acquisition process offering 24-hour initial property review and a referral commission (Tippgeberprovision) program for sourced leads. Its portfolio spans residential Altbau renovations (e.g., Meinekestrasse/Maison Fleuron, Marburger Strasse), new-build apartment buildings, and commercial campuses (notably the 60,000 m² Markgrafendamm sold in Q4 2020 and the 5,177 m² Rhinstrasse Bestand). Geographically, TTI focuses on Berlin and adjacent Brandenburg (within 60 minutes of Berlin HBF), serving as both a developer (Bauträger) selling completed projects to other developers or investors, and a long-term holder (Bestandshaltung) generating recurring rental income from anchor tenants including the Berlin Senate Department for Education and TÜV.

Revenue is generated primarily through one-time property development and sales, supplemented by recurring rental income from held assets. Pricing is individually negotiated and not publicly disclosed. TTI holds a §34c GewO (Gewerbeordnung) license issued in 2011 for real estate brokerage and development, and operates with a very lean inhouse team (1-10 employees) supplemented by an external network of established architectural firms including Tchoban Voss Architekten, Axthelm-Rolvien, and Nöfer Architekten. The company does not use proprietary technology in its core business; no AI/ML capabilities, APIs, or software platforms are disclosed.

Beyond traditional development, TTI operates a ventures and incubation arm called tti vision, which invests as a business angel in early-stage Legal Tech (Miles), eCommerce (Nucleus Capital), and PropTech (Casenio, Sunfish, Inhubber) startups, and runs a temporary event venue (NEUZEIT OST) on a development site. The company is a member of industry associations including VBKI (Verein Berliner Kaufleute und Industrieller) and Außergewöhnlich Berlin.
