Promptwatch raises €6M to help brands appear in ChatGPT, and the week funding split into three tiers. A seed round for AI chatbot visibility, a $1B non-equity deal for a longevity drink, and stablecoin payments close a $38M Series A. Published July 15, 2026 The capital markets are still open, but the check sizes this week tell three different stories. On one end: a €6 million seed round for a startup that wants your brand to show up when someone asks ChatGPT for a recommendation. On the other: a $1 billion deal that doesn't involve equity at all, just a beverage company co-founded by a retired footballer. In between, there's a $38 million Series A for stablecoin payment rails, which is the sort of thing that makes sense only if you believe cross-border B2B payments are still broken enough to justify another layer. Promptwatch wants brands to rank in AI chatbots. Promptwatch raised €6 million in a seed round led by Seed + Speed Ventures, with Blum Ventures and Arches Capital also backing the Amsterdam startup. The pitch: help brands improve their visibility inside conversational AI tools like ChatGPT, Claude, and whatever Google is calling Gemini this week. The company has already opened an office in New York and says it will use the funding to expand there. The idea isn't particularly new - SEO consultants have been saying "optimize for LLMs" since late 2023 - but turning it into a funded SaaS product with enterprise contracts is the next logical step. If people are using chatbots instead of search engines to find restaurants, hotels, or software tools, then brands need a way to ensure they show up in those answers. Promptwatch is betting that most companies don't know how to do that yet and will pay someone to figure it out for them. Whether this becomes a durable category or just a feature that OpenAI and Anthropic eventually build into their enterprise tiers is the open question. For now, there's clearly investor appetite for "AI discovery" infrastructure. Velocity closes $38M to put stablecoins into business payments. Velocity announced a $38 million Series A led by Dragonfly and Firstmark, with participation from Coinbase, Capital One Ventures, QED Investors, Activant Capital, Ripple, and Wintermute. The London-based payments company is building tools that let businesses integrate stablecoins into customer checkout flows and cross-border invoicing. This is the kind of round that makes sense if you've spent any time watching a wire transfer sit in limbo for three days or trying to pay a contractor in another country without losing 4% to FX spreads and intermediary fees. Stablecoins are supposed to fix that - instant settlement, transparent fees, no correspondent banking network. The hard part has always been making it easy enough for a mid-market business to actually use without hiring a crypto-native payments engineer. Velocity's investor list is a mix of traditional fintech funds (QED, Capital One) and crypto infrastructure players (Dragonfly, Coinbase, Ripple). That split suggests the company is threading the line between "this is just better payments infrastructure" and "this only works if you believe in on-chain rails." The $38M will likely go toward compliance, integration partnerships, and convincing CFOs that stablecoin invoicing is less risky than it sounds. IM8 gets $1 billion in non-equity financing from General Catalyst. Here's where the week gets weird. IM8 secured $1 billion from General Catalyst's Customer Value Fund, which is not a traditional venture fund - it doesn't take equity. Instead, it provides financing to companies in exchange for revenue share or other non-dilutive terms. IM8 is a longevity vitamin-drink startup co-founded by David Beckham, which makes this one of the stranger capital allocation decisions of the year. The structure suggests IM8 either didn't want to give up board seats or couldn't raise a traditional round at a valuation it liked. General Catalyst's fund is designed for companies with strong unit economics that need capital for manufacturing, inventory, or distribution - things that don't require giving up control. Whether a celebrity-backed beverage startup fits that profile is debatable, but $1 billion is $1 billion. This is also a signal that large institutional funds are experimenting with non-equity structures, especially for companies in categories (CPG, hardware, physical infrastructure) where venture's traditional "grow at all costs, exit in 7 years" model doesn't fit cleanly. The rest of the funding roundup. A few other deals worth noting: * Monorale AI raised £4 million in a Series A after hitting 40,000 users in eight months. The British AI platform didn't disclose what it does, which is becoming a genre. * Flex raised $70 million led by Halo Fund to build AI-powered banking tools for mid-sized business owners, per Reuters. * TYLSemi closed $43 million to help companies design their own AI chips, founded by former AlphaWave executives. * Cyera raised $600 million at a $12 billion valuation in June for AI-enabled enterprise security, especially around AI agents. The pattern: seed rounds are getting smaller and more focused, Series A checks are going to infrastructure plays (payments, chips, security), and the billion-dollar deals are either non-equity or happening in China. If you're raising right now, the tier you're in matters more than the category.

Unblockpay, a Brazilian fintech specialising in global payments via stablecoins, has raised $4.5 million (R$23.6 million) in a seed round led by London-based Prelude, valuing the company at $20 million (R$105 million). Plug Pay, Wintermute, Crescera and Triaxis also participated. Founded by former Stone partners, the company has processed over R$100 million and serves 40 clients, including Mercado Bitcoin. It currently has ten employees and operates across 34 European countries plus the US, UK, Mexico, Argentina and Colombia. Part of the funding will support regulatory compliance as Brazil's Central Bank implements new rules for virtual asset service providers. The company also plans to expand its team and connect to the Swift network. Unblockpay expects to process R$1 billion monthly by year-end.
