Company profile
researched Aug 2026TextCortex (legal entity Text Cortex AI UG) is a Berlin, Germany software company founded in 2021 by Ceyhun Derinbogaz and Dominik Lambersy [7]. It began as an AI copywriting and text auto-generation platform, offering description generators for SEO content, blog posts and articles, marketing copy and product descriptions, customer support emails, YouTube descriptions, Facebook ad copy and Instagram captions, delivered largely through a browser extension usable in email, documents and e-commerce contexts [6][7]. Early technology centred on a proprietary network of fine-tuned language models the company calls NeoCortex, which it positioned as a European alternative to very large models, stating that most models running within NeoCortex were about 1% of the size of a 175-billion-parameter model and therefore required less compute and energy [5].
The current product is positioned as enterprise agent infrastructure: a platform to organize, deploy and govern AI agents across an organization. Components include a no-code visual agent builder, a model hub providing access to multiple major model providers without single-vendor lock-in, knowledge search that connects internal documents, wikis and tools alongside web sources, a node-based visual editor for multi-step workflow automation, scheduled/recurring agent runs with results delivered by email, and integrations that let users @mention agents in tools such as Slack and Microsoft Teams or work through a browser extension across a large number of apps and sites [0][1]. The company emphasizes European data sovereignty, stating GDPR compliance, ISO and SOC 2 certification, and that customer data is not used for model training [0][1]. A separate consumer/prosumer line includes a Mac desktop app (beta, with a Windows waitlist) built around an assistant named "Zeno" that supports highlight-to-rewrite, expansion, summarization, grammar correction and more than 25 languages [2][4].
TextCortex also runs a help center covering onboarding, products and integrations, settings and billing, and release notes [3]. The company frames its market entry around friction in enterprise AI adoption: generic copilots that do not fit complex workflows, unused in-house bots, and "shadow AI" from unapproved tools, and it pairs the platform with a rollout framework it describes as proven in DACH enterprises [0][1].
Founding story
Co-founders Dominik Lambersy and Ceyhun Derinbogaz met at Entrepreneur First in Berlin. Lambersy came from a VC background and had worked on NLP algorithms; Derinbogaz had built a range of NLG-based products including domain-name and product-description generators. The company was founded in 2021 to build natural language generation technology for everyday writing, with the aim of taking users from bullet points to a substantially complete draft in one click [5][6][7].
Business model
TextCortex sells software as a subscription. Preqin describes revenue generated through software subscriptions with pro and business packages available on a monthly basis [7]. The website offers a free entry point ("Start for free") alongside a sales-led enterprise motion built around booked demos, plus a hands-on partner/adoption service layer around the platform [0][1].
Subscription software revenue, historically via monthly pro and business packages [7], with a freemium entry point and enterprise deals sold through demos on the current site [0][1].
Traction
The website reports 2.4 million users worldwide, a 4.9 rating from more than 2,500 reviews, and customer-case figures including $550,000 saved per 100 enterprise users per year (from a study of 2,000 enterprise users), 75% enterprise adoption within three months, 52% less time spent writing to clients, 5+ hours saved per employee per week, 71% activation rate, 100+ agents deployed, 94% increased work quality, 67% increased confidence in AI, and 12% faster proposal creation [0][1]. Earlier data points: roughly 7,000 users and a team of nine across five countries at the June 2022 pre-seed [5], and 10,000 platform users as of July 2022 per Preqin [7].
Latest developments
The company's current site positions TextCortex as enterprise agent infrastructure with a visual agent builder, model hub, knowledge search, scheduled automations and Slack/Teams integrations, and advertises GDPR compliance plus ISO and SOC 2 certification and 2.4 million users worldwide [0][1]. A Mac desktop app is offered in beta with a Windows waitlist [2].

Market position
Positioned as a European, sovereignty-focused alternative to generic copilots such as Microsoft Copilot and ChatGPT for enterprise agent deployment [0][1]. The company cites a Top 10 Best AI Software Product listing on G2 and a 4.9 rating from over 2,500 reviews, and states it was named by DT2 Invest and the European Commission among the top 200 generative AI companies/AI startups in Europe [0][1][2][4]. At founding it described entering a crowded market of AI copywriting tools, most of which repurposed a single well-known API, differentiating by building its own NLG models [5].
Stated differentiators include no-code agent creation, model-agnosticism to avoid provider lock-in, connection to company knowledge for context-aware actions, delivery inside existing tools rather than a separate interface, European data sovereignty with GDPR/ISO/SOC 2 and no training on customer data, and an accompanying adoption framework targeting more than 75% user adoption within 90 days [0][1]. Earlier differentiation rested on proprietary, smaller fine-tuned models (NeoCortex) rather than reselling a third-party API [5].
Technology
A model-agnostic platform layer providing access to major third-party models plus a visual, no-code agent builder, node-based multi-step workflow automation, scheduled agent execution, and knowledge search over connected internal documents, wikis and tools as well as the web [0][1]. Delivery surfaces include Slack and Teams integrations, a browser extension and a Mac desktop application [0][1][2]. Historically the company developed NeoCortex, its own network of fine-tuned natural-language-generation models sized at roughly 1% of a 175-billion-parameter model to reduce compute and energy use [5]. Stated compliance posture: GDPR, ISO and SOC 2, with zero data training [0][1].
Go-to-market
Product-led entry through a free tier, a Chrome/browser extension and a Mac desktop app, combined with enterprise sales via demo requests and case studies [0][1][2][5]. The company distributes an "AI Adoption Playbook" rollout guide as a lead magnet and cites a DACH enterprise adoption framework [0][1]. Distribution is also embedded in existing workplace tools, with agents invoked via @mention in Slack and Teams and a browser extension spanning tens of thousands of apps and sites [0][1][2].
Enterprises deploying and governing AI agents across teams, particularly those with security, compliance and European data-sovereignty requirements [0][1]. Earlier positioning targeted individual writers, marketers and e-commerce sellers; Preqin lists a client base including Envato, Upwork, Etsy and Shopify [6][7].
Geography
Headquartered in Berlin, Germany [7]. At the 2022 pre-seed the team of nine was distributed across five countries on three continents [5]. Product positioning emphasizes European data sovereignty and a DACH enterprise adoption framework [0][1].
History
Founded in 2021 in Berlin as an AI copywriting and text auto-generation platform [7]. In June 2022 it announced a $1.2 million pre-seed round led by btov Partners with Speedinvest and Entrepreneur First and angels Amar Shah and Holger Hengstler, and launched a Chrome extension; the team then numbered nine and the product had roughly 7,000 users [5][6]. Preqin records the same round as EUR 1.12 million [7]. The product line later expanded to a Mac desktop app in beta with the "Zeno" assistant and, more recently, to an enterprise agent infrastructure platform covering agent building, governance, workflow automation and integrations [0][1][2][4].
Risks & controversies
No controversies are reported in the available sources. Reported traction and ROI figures (users, savings, adoption and activation rates) are self-published by the company on its own website and are not independently verified [0][1]. Sources also give inconsistent figures for the pre-seed round size (USD 1.2 million versus EUR 1.12 million) [5][6][7] and for review counts and integration breadth across pages (4.9 with 2,500+ reviews and 30,000+ apps versus 1,500+ reviews and 10,000+/50,000+ platforms) [0][1][2].
