Latest / The Series A Show with Fexingo: Early-Stage Funding, Pitch Decks, and Startup Milestones / Why Early-Stage Startups Pitch a Watermark Slide
Transcript
- Lucas: So Anthropic finally shared how Claude's watermarking is going to work, and I think for founders in the room, this is the moment the pitch deck gets a new slide. I've seen three decks this week alone that added a 'content provenance' slide — each one was a direct response to the watermarking news. Luna: Really? A whole slide just for watermarking? That seems like a lot of real estate for a technical detail. Lucas: It sounds technical, but it's actually a trust slide. Investors are terrified of funding a startup that gets slapped with a misinformation lawsuit or becomes a vector for AI slop. A watermarking slide says: we've thought about provenance, we know how to label synthetic content, and we're ready for the regulation that's looming. Luna: Right, because the EU's AI Act is already forcing transparency, and the US is starting to talk about disclosure requirements. So investors want to see that box ticked. Lucas: Exactly. And the irony is, a lot of these startups aren't even building their own models. They're using OpenAI, Anthropic, or Google APIs. But they still need to show how they'll handle ai generated content in their workflow. The slide is less about the tech and more about governance. Luna: So what does a good watermark slide look like? Is it just a screenshot of a watermark in action? Lucas: The best ones I've seen actually have three components. First, they state the problem: '80 percent of online content will be ai generated by 2027,' or something similar. Then they show their solution — a simple diagram of how content flows and where the watermark gets embedded. And finally, they show a customer quote or a pilot result, proving that real users care about this. Luna: And what about the skepticism? Some people argue watermarking is trivial to strip, and it's not a real moat. Lucas: That's a fair challenge, and the good founders address it head-on. They'll say: 'We know watermarking isn't perfect, but it's a first line of defense, and we're combining it with detection algorithms and content registries.' Investors appreciate that honesty more than a fake promise of perfect security. Luna: So it's not just about the slide itself, it's about how the founder handles the pushback in the room. Lucas: Right. The slide is the opening, the Q&A is where they prove they've actually thought about it. And with Anthropic making watermarking mainstream, every investor is going to ask: 'What's your approach?' If a founder says 'We haven't thought about it,' that's a red flag. Luna: And it's not just for ai native startups. I saw that PayPal might be sold to Stripe and Advent — that's a huge deal, but even a company like PayPal could have a watermarking story if they're dealing with deepfakes in payments. Lucas: That's a great point. Payments are a perfect example. Imagine a scam call with a cloned voice authorizing a transaction. If you have a watermarking or provenance layer, you can verify authenticity. So this slide isn't just for content platforms — it's for any startup touching media, communications, or even financial services. Luna: So how does a founder actually craft that slide? Any tips for the wording? Lucas: Keep it simple. One sentence on the problem, one on the solution, and one on the traction. For example: 'ai generated content is exploding, and consumers are losing trust. Our platform embeds cryptographic watermarks into every synthetic asset, and we've already processed two million images with a 99.2 percent detection rate.' That's it. Luna: That's clean. And then the founder can dive into the technical details if asked, but the slide itself is scannable in thirty seconds. Lucas: Exactly. And the interesting thing is, I've seen this slide work even for startups that aren't purely AI. One company in the ad-tech space added it because they use AI to generate ad creatives. Their investors loved it because it showed they were thinking about brand safety and regulatory compliance. Luna: So it's basically a way to de-risk the story. Investors can check the box on 'AI governance' and move on. Lucas: And that's why it's becoming a must-have. In this funding environment, where every term sheet is scrutinized, a small slide that signals responsibility can make a big difference in the room. Luna: And speaking of the room, I know our listeners are often founders or operators. If today's conversation has been useful for what you're building, the way we keep these episodes ad-free is through listener support. You can buy me a coffee at buy me a coffee dot com slash fexingo. It's a small gesture, but it keeps the lights on. Lucas: Yeah, we really appreciate that. We're not backed by a network, and listener contributions are what let us stay independent and dive into these niche topics. Luna: And now back to watermarking — I've also seen some founders use the slide to talk about their own internal AI usage. Like, 'We use AI in our product, but we're transparent about it.' Lucas: That's a smart angle. If your product is ai first, showing that you're transparent with your own users builds trust. And it preempts any questions about 'black box' behavior. Luna: So, what about the counter-argument? Some founders worry that adding a watermarking slide makes them look like they're solving a problem that might not be their biggest priority. How do you respond to that? Lucas: I'd say look at the market. The news cycle is full of AI disinformation stories, and regulators are moving. If you're not addressing it, your competitor will. It's like having a cybersecurity slide in 2018 — it became table stakes. Luna: Good point. And in terms of the actual implementation, is there a standard approach? Like, are they using C2PA or something? Lucas: The largest players are coalescing around C2PA, the Coalition for Content Provenance and Authenticity. But there's also decentralized options, and some startups are building their own lightweight watermarks. The slide doesn't need to commit to one standard — it just needs to show the founder has a point of view. Luna: So a founder can say, 'We're standard-agnostic, but we're aligned with the major initiatives.' Lucas: Right. And in the Q&A, they can discuss the trade-offs. For example, some watermarking methods degrade image quality, so how do you balance that? A thoughtful answer shows more depth than just a checklist item. Luna: And given that Anthropic is rolling out watermarks for Claude, do you think that will make the slide even more common? Like, suddenly every AI startup will want to show they're compatible with Claude's approach? Lucas: Absolutely. If you're building on Claude, you can say, 'Our outputs are automatically watermarked via the API.' That's a major selling point. And for startups using multiple models, they can highlight their ability to handle provenance across all of them. Luna: That's a nice tie-in with the broader trend of AI governance becoming a centerpiece in enterprise sales. Lucas: Exactly. And it's not just about deepfakes. Even something as simple as marketing copy generated by AI, if it's watermarked, you can audit what was created by a human and what wasn't. That has content quality and legal implications. Luna: So for founders listening, how early should they start thinking about this? Is it a seed-stage thing or more Series A? Lucas: I'd say as soon as they have an AI component in their product. Even at seed, you can mention it in a slide. But by Series A, when investors are digging into due diligence, they expect to see a considered approach. So if you're planning to raise in the next six months, it's time to add it. Luna: And what if a founder hasn't implemented watermarking yet? Is it a deal-breaker? Lucas: Not necessarily, but they need to show they have a roadmap. Investors are more forgiving if you say, 'We're evaluating C2PA and plan to integrate in Q4,' versus 'We haven't thought about it.' Luna: That makes sense. So it's about demonstrating awareness and intent, not just having the perfect solution. Lucas: And that's the broader theme of this episode: in 2026, the bar for AI startups is higher. It's not enough to build a great model — you need to show you're a responsible steward of the technology. The watermark slide is a shorthand for that. Luna: I love that. And I think it's a trend that will only deepen, especially as more regulations come online. I wouldn't be surprised if in a year, every Series A deck has a version of this slide. Lucas: I think you're right. And the founders who get ahead of it now will have an edge. So if you're preparing your deck for next month's fundraising, consider adding that slide. It might be the detail that sets you apart. Luna: And for our listeners, if you have questions about how to implement this in your own pitch, we're happy to hear from you. But for now, thanks for joining us on The Series A Show. Lucas: Until next time, keep building.
