The most interesting place to put an AI assistant might be the one place you never have to open a new app. For Marvin von Hagen and Felix Schlegel, that place is the iMessage thread you already have pinned, the WhatsApp chat you check every five minutes, or the SMS inbox you can't ignore. Their startup, The Interaction Company of California, is building Poke, an AI that lives inside those native messaging platforms, connecting to your calendar and email to draft, schedule, and follow up on your behalf. It's a bet on ambient computing, where the interface disappears, and the assistant just works in the background of the conversations you're already having. The company has convinced General Catalyst and a roster of high-profile angels to back that vision with $25 million in total seed funding, valuing the young firm at $300 million post-money [X, Sep 2025][Palo Alto Today, 2026].
The wedge is the thread
The Interaction Company's product thesis is simple, but its execution is not. Poke is designed to function as a single contact in your messaging app,a thread that links to your files, calendar, and emails before taking action [Employbl, 2025]. The goal is to handle the entire communication workflow: comprehending an incoming message, drafting a reply, suggesting a meeting time from your calendar, and sending a follow-up, all through natural text. The company claims it uses the AI model best suited for each task, whether from major providers or open-source alternatives [Yahoo Tech]. For users, the value proposition is frictionless access; there's no app to download, and the assistant is available wherever they already text [Yahoo Tech]. This positions Poke not as another standalone chatbot, but as a unified layer embedded within the digital spaces where personal and professional communication already happens.
A founder story built on systems engineering
The founders bring a specific kind of credibility to this technically ambitious build. Marvin von Hagen and Felix Schlegel are long-time collaborators with combined AI research and systems engineering experience from Stanford, MIT, Cambridge, Tesla, and Apple [General Catalyst, 2025]. Their most tangible proof of capability, however, predates their AI work. While still students, they founded TUM Boring, leading a team of 65 engineers to design and build a 22-ton tunnel boring machine. That project won SpaceX's Not-a-Boring Competition, a credential that speaks to their ability to manage complex, hardware-and-software systems at scale [General Catalyst, 2025]. That background in deep systems work is now being applied to the messy, unstructured problem of human communication. The broader engineering team draws from Jane Street, Apple, Robinhood, and Amazon, suggesting a hiring bias toward rigorous technical backgrounds [General Catalyst, 2025]. Both founders were named to the Forbes 30 Under 30 list for AI in 2026 [Forbes, 2026].
Funding and the path to a $300 million valuation
The company's rapid fundraising tells a story of investor conviction in both the team and the wedge. The initial $15 million seed round in 2025 was led by General Catalyst at a $100 million valuation [X, Sep 2025]. That round included participation from Earlybird Venture Capital and Village Global, and an angel list that reads like a who's who of tech and finance: Scott Wu, Ken Howery, Fred Ehrsam, Cory Levy, and Guillermo Rauch, among others [X, Sep 2025]. Less than a year later, the company added a $10 million seed extension, bringing its total disclosed funding to $25 million and its post-money valuation to $300 million [Palo Alto Today, 2026]. This capital runway allows the team to focus on product development and user growth without immediate monetization pressure, a common strategy in consumer-facing AI.

The retention challenge in a consumer inbox
For all its technical promise and investor enthusiasm, The Interaction Company faces the classic consumer AI adoption puzzle. The product is inherently personal, requiring deep access to a user's private communications and calendar. Trust and utility must be established quickly, and the value must be obvious enough to change ingrained messaging habits. The competitive set is also evolving quickly.
- Platform-native features. The greatest long-term risk may not be a direct startup competitor, but Apple, Google, or Meta deciding to build similar proactive assistance directly into iMessage, Gmail, or WhatsApp. The EU's antitrust probe into Meta over plans to potentially block AI rivals on WhatsApp underscores the platform risk here [Reuters, 2025].
- Standalone agent apps. Companies like Linq are also enabling AI assistants within messaging apps, creating a category where Poke must differentiate on the quality of its proactive actions and integration depth [TechCrunch, Feb 2026].
- Horizontal AI assistants. Broad-based assistants from OpenAI, Google, or others could expand their capabilities into the same communication workflows, leveraging their massive distribution.
The company's answer likely hinges on its focus on being a single, unified thread that acts end-to-end, and the founders' systems-level approach to making that experience reliable. The seed extension gives them time to prove that users will not just try Poke, but keep it as a permanent contact.
The next twelve months
The immediate roadmap will be about scaling the beta. The company has already tested with over 6,000 users who sent more than 200,000 messages monthly, providing a foundation of real-world interaction data. The next phase will involve expanding that user base while refining the AI's proactive capabilities,the "anticipates users' needs before they ask" promise that separates it from a reactive tool [WebWire, 2026]. Monetization is a future concern; for now, the focus is on engagement and retention metrics that would support a future Series A. The ideal customer profile is clear: a busy professional, likely in a tech-adjacent field, who manages a high volume of scheduling and communication across multiple messaging platforms and feels the cognitive drain of context-switching. For them, Poke isn't another app; it's a utility that reduces the overhead of the apps they can't quit. The realistic competition isn't just other AI startups, but the inertia of the status quo and the feature roadmaps of the platform giants who own the inbox. The Interaction Company's bet is that by living inside the thread, they can become indispensable before anyone else gets there.
