Kontext Raises $10M to Scale AI-Powered Advertising in Generative AI Apps
Kontext, a startup building AI-driven advertising infrastructure for generative AI applications, secured $10 million in seed funding as of April 2025. The company’s contextual advertising platform dynamically generates ads within AI chatbots and conversational interfaces, claiming up to a 66% increase in revenue for partner publishers.
Founded in 2023, Kontext operates with a lean team of 13, serving major brands like Amazon, Uber, and Canva. The funding round was led by M13, with Torch Capital, Credo Ventures, and Parable VC also participating. The capital will support growing the team, improving infrastructure, and scaling demand.
Real-Time Ad Creation Within AI Conversations
Unlike traditional banner ads, Kontext's technology produces advertisements in real-time, embedded directly in chatbots’ user experience. Using the same large language models that power conversational AI, Kontext analyzes user queries and session context to generate relevant branded links right beneath chatbot responses.
Partner publishers include DeepAI, Media Search, Pixel Chat, and Spicy Chat. Reported results show average revenue per user increasing from $0.24 to $0.40 when integrating Kontext’s ads, a 66% lift that signals strong monetization potential within generative AI apps.
Proven Campaign Performance
A pilot campaign with mobile game developer Nimblebit for its game Tiny Tower demonstrated promising results. The campaign achieved a 1.58% click-through rate and cost-per-install under $2. Kontext’s performance exceeded Facebook campaigns by 24% while maintaining a CPM of $2.50 versus Facebook’s $7.35.
Kontext operates on a revenue-sharing model, taking 25-30% from filled ad demand and charging success fees between 20-30% of lifetime value for premium publisher upsells.
Filling the AI Advertising Infrastructure Gap
Kontext positions itself at the forefront of the shift from mobile to AI-powered consumer apps. The company highlights a missing layer in advertising infrastructure for AI applications, contrasting with established systems like AdSense and TheTradeDesk built around web and mobile platforms.
The startup estimates a $500 million revenue opportunity in GenAI text publishers alone, signaling growing demand for AI-native ad solutions as generative AI gains mass-market traction.
Technical Approach and Advantages
Kontext’s platform generates ad copy dynamically from conversation context, a significant departure from static creative assets in traditional advertising. This approach demands advanced natural language processing and considerable computational resources.
Text-based ads are the most cost-effective format given the high marginal costs of AI inference. This makes ad-supported monetization particularly attractive for free user tiers of generative AI products, helping publishers diversify revenue beyond subscription models.
Competitive Landscape
The startup competes with smaller firms like OpenAds.AI, Abotify, Prompt Ads, and Koah, which have limited funding and traction. Major tech companies—Google, Meta, Microsoft, and TheTradeDesk—are potential competitors but currently lack real-time ad generation capabilities for third-party ads within AI chatbots.
Kontext argues that adapting existing ad tech stacks to real-time creative generation and maintaining brand safety around AI-generated content presents a significant barrier for incumbents.
Experienced Team with AI and Ad Tech Expertise
The team includes seven co-founders with prior startup experience and over 400 citations in AI research. Leadership features Jan Matas, former Deepnote CTO, and Andrej Kiska, co-founder of Credo Ventures and early investor in UiPath and Eleven Labs.
The technical depth spans AI research, infrastructure, and advertising technology, equipping Kontext to handle the unique challenges of ad generation and scaling within AI applications.
Publisher Revenue Impact
Testing shows that integrating Kontext’s ads increased Average Revenue Per User (ARPU) from $0.24 to $0.40. Additionally, ad-supported users converted to paid subscriptions at higher rates (2.13% vs. 1.46%) and generated greater total subscription revenue, suggesting ads complement rather than cannibalize subscription growth.
Industry Trends and Market Timing
The funding comes as advertising adoption accelerates across AI platforms. Netflix’s 2022 launch of an ad-supported tier and Google’s extension of AdSense to AI chatbots exemplify this shift. Currently, 86% of buyers use or plan to use generative AI for ad creation, reflecting growing acceptance of AI-driven advertising.
Technical Architecture and Challenges
Kontext’s system integrates with AI apps while maintaining chatbot response speed. It must analyze conversation context, select suitable advertisers, generate relevant ads, and deliver them within tight response times.
Challenges include ensuring brand safety, maintaining ad relevance across diverse topics, handling computational loads for millions of daily interactions, and supporting targeting and optimization without degrading user experience.
Revenue Model and Market Opportunity
As AI consumer apps like ChatGPT, Character.ai, and Perplexity scale, Kontext aims to capture a growing share of advertising spend. Historical valuations of web and mobile ad platforms—AdSense ($300B), TheTradeDesk ($70B), AppLovin ($110B)—illustrate the potential size of the AI ad infrastructure market.
The $140 billion open web advertising market underlines the opportunity as AI-driven apps compete for user attention.
