Andrej Kiska Jr., co‑founder of Credo Ventures and a prominent figure in Central European venture capital, moved his family to Palo Alto in spring 2025 to found Kontext. The startup aims to change how advertising works in generative AI chat interfaces by analyzing conversations in real time and generating ads that match the user’s immediate intent instead of relying on past behavior.
Background: why his track record matters
Kiska arrives to product building with years of VC experience. Credo Ventures, which he helped build, ultimately delivered more than tenfold returns and was ranked among Europe’s top funds by the European Investment Fund. Standing at the peak of VC success after the UiPath IPO in 2021, Kiska began to question whether continuing as a venture investor was what he wanted, and chose to switch to founding his own company.
Entrepreneurship runs in his family: his father, id. Andrej Kiska, built businesses and turned to philanthropy, later winning the Slovak presidential election in 2012. Kiska Jr. has been deliberate about crafting a career outside Slovakia so he would not be defined as simply “the president’s son.”
Credo’s near‑death and eventual success
Credo’s early years were difficult: like many VC funds it experienced the J‑curve, and roughly three years after launch it faced harsh criticism and calls from a major investor to halt further funding. Several investors ultimately backed the team and the fund survived. From its second fund it grew into one of Europe’s most successful VC firms, supporting companies that later became notable successes in the region.
Why chatbot ads?
Kiska argues that each new dominant mass platform creates a new advertising format: search ads with Google, social ads with Facebook, and mobile monetization with companies like AppLovin — whose market value is about $140 billion. He sees generative AI chatbots as the next major platform shift and believes Kontext can become a leading player by serving ads embedded in conversations that match a user’s present intent. For example, if a user asks a chatbot for hiking advice, Kontext’s approach can surface a waterproof backpack as part of the dialogue, rather than as a separate banner.
The move to Palo Alto and early product work
In spring 2025 Kiska relocated to California with his wife and three children, despite having no finished product, customers, or guaranteed funding. The move was partly pragmatic: many of the largest chatbot and AI infrastructure providers are located in the Valley, and being nearby can accelerate partnerships and product iteration. The first months were emotionally demanding for the family, but the relocation also enabled rapid access to potential clients.
Kontext pursued customer conversations and pilots before building: one early meeting with Perplexity produced a strong signal — Perplexity said they would buy the solution. (Perplexity’s valuation is noted in the source as more than $26 billion.) Kiska decided not to sell; instead he used that interest to continue building.
Early traction and financing
Kontext ran initial campaigns for clients including Uber, MasterClass and Blizzard; according to the company’s results, in‑chat ads received roughly twice the click‑through rate compared with comparable ads on traditional platforms. In August 2025 the startup closed a $10 million seed round with investors such as M13, Torch Capital, Parable VC — and Credo Ventures among them.
Competitive landscape
Major AI companies have already started to enter the ad market around chat interfaces. OpenAI began testing ads in the U.S. in February 2026, with reported ad pricing around $60 CPM — roughly three times Meta’s average price level cited in the source. Google announced in December 2025 that it will introduce ads in Gemini in 2026, leveraging its large, multibillion‑dollar advertising business.
Kiska emphasizes that being based in Silicon Valley makes it easier to work with these platform providers and to be part of the ecosystem where the largest chatbot and infrastructure players operate.
Personal goals and outlook
Kiska frames his decision less as a pursuit of an ‘unicorn’ label and more as a choice to follow decisions he believes are right even if others call them crazy. The source notes that he could become the first Slovak founder to reach a billion‑dollar valuation, but Kiska himself stresses learning and purposeful work over chasing status.
For Kontext the near‑term routes are further product development and scaling with additional funding rounds, or possibly a strategic acquisition by a larger AI platform. By late summer the company’s progress and financing will clarify which path is likelier, but the early pilots, Perplexity’s interest and the $10 million seed round signal clear market attention.
Summary
Kiska’s trajectory from Central European VC to Silicon Valley founder illustrates a bet on the advertising potential of generative AI chatbots. Kontext’s early pilots and seed financing in 2025 indicate initial validation, while competition from major AI players underlines both opportunity and pressure in the emerging chat‑ad market.
