About Simula
Summary
Simula is a San Francisco-based adtech startup, founded in 2025, that builds advertising infrastructure purpose-built for AI-powered applications. Rather than porting conventional banner or interstitial formats into AI products — where they tend to disrupt the user experience — Simula designs ad units that blend naturally into AI-driven interfaces. These include interactive formats such as AI brand ambassadors and games played alongside AI companions. The company appears to be integrating its technology across a growing set of AI apps and is targeting a user base in the tens of millions of daily active users. The five-person team brings backgrounds spanning app development at scale and roles in the advertising industry.
Business model
Simula likely operates on a revenue-share or CPM-based model, taking a portion of the advertising revenue generated through its ad formats on partner platforms. Its pricing angle centers on delivering ad experiences that preserve — rather than degrade — user engagement, which aims to justify stronger monetization rates compared to traditional ad placements.
Go-to-market
Simula's primary customers are developers and publishers of AI-native applications who need a way to generate advertising revenue without compromising the conversational or interactive quality of their products. The buying motion appears to be a direct integration partnership, where Simula embeds its ad infrastructure into a partner app's existing experience. Likely acquisition channels include outreach to AI app developers and word-of-mouth within the consumer AI ecosystem, given the early-stage, partnership-driven nature of the rollout.
