About
I build AI systems for the two things every company needs to grow: capital and customers. On the capital side: whether you're closing a seed round from VCs, Fund I from LPs, or a real estate raise from family offices, the loop is the same. Find named investors. Write personalized outreach. Send at scale. Close the round. On the customer side: same shape, different game. Create the campaigns, run them across Meta, Google, TikTok, and LinkedIn, analyze what's working, and optimize in real time. The teams that win aren't the ones with the biggest budget. They're the ones with the fastest-learning system. Most founders and operators waste 40+ hours a week on work that should be automated, on both sides. The systems I build solve that. They live across three products and two publications, and they're the same ones I use on my own raises and my own marketing. A short version of how I got here: → At 17, e-commerce. Learned that distribution beats product 9 times out of 10. → Early 20s, paid media for D2C brands across Spain and the UK. → Then a digital marketing and development agency. Shipped a lot of products before I closed it down to focus on what came next. → Then crypto and Web3. Helped companies raise in pre-sales from thousands of investors across every type and geography. Built the muscle for fundraising under volatility. Today, I'm building in parallel: → EleveX. Co-founder and COO of the real estate tokenization platform that opens institutional, HNWI, and retail capital to developers via secondary exchanges. → 8raise. After personally closing €10M and helping founders close €15M+, I built the investor discovery MCP for Claude, ChatGPT, and Perplexity. 450K+ named investors, ranked, in 90 seconds. → 8MKT. Marketing run on AI across the whole function: content creation, GTM, distribution, and paid media as one piece of it. The marketing team of 2030 is a handful of operators running dozens of AI agents, and we're building the layer that makes that real. → Two Substacks with my co-founder Ignacio: 8fundraising (raising capital) and 8MKT (AI marketing). 8fundraising hit Top 90 Bestsellers in Business, Top 7 New Bestsellers & Top 10 in Business on Substack after week two. 5M+ LinkedIn impressions in 60 days, from zero. The pattern across all of it: I get obsessed with problems and can't stop until I've shipped something that solves them. Tokenization. AI automation. Fundraising. Marketing. The obsession is the whole thing, not the obstacle. Raising right now? Scaling your marketing with AI? Building in any of this? DM me.

Why work with me
I build AI systems for the two things every company needs to grow: capital and customers. That means I reach two rooms most creators can't put in one place. Raising capital: founders running venture rounds, fund managers raising LP capital, real estate sponsors raising for deals. Decision-makers with capital in motion, hard to reach anywhere else. Running marketing: marketing operators, founder-marketers, GTM and sales leaders, agencies, and e-commerce founders building paid media on AI. The audience holds budget: 39% Founder / C-level, 40% founders by function, plus Marketing and Finance / VC. ~35K average views per post, 5M+ LinkedIn impressions in 60 days, and content that books ~250 qualified calls per month for the products I promote. I don't run banner placements. Your product shows up inside the real workflow I'm already writing about, which is why it converts.
What I offer
Two lanes. You pick the one your buyer reads. Your product lands native in that context, never blended with the other. FUNDRAISING LANE — for the room raising capital Best fits: investor CRM and outreach, cap-table, data-room and pitch software, fund admin, fundraising platforms. MARKETING LANE — for the room running growth Best fits: AI marketing and paid-media tools, ad-platform and GTM software, content and creative tools, attribution and analytics, e-commerce growth. Formats (either lane): - Single post in my voice, built around your product inside a real workflow - One month, 4 posts, for repeated exposure - Cross-channel partnership: my co-founder Ignacio and I run a full month across both LinkedIn profiles plus the matching Substack (8fundraising or 8MKT). This is where the call-booking numbers come from. Horizontal product used on both sides? Run both lanes as two separate native placements. Not a fit: get-rich-quick or guru courses, crypto tokens and memecoins, MLM, guaranteed-returns products.
How I work
You send a brief and tell me the lane. I write the post in my voice and place it inside real fundraising or real marketing content so it reads as editorial, not an ad. Each post anchors a comment-to-DM CTA, which is what drives the comment volume and routes interested buyers to a conversation. You get the qualified inbound. I keep editorial control so it lands, and I keep the two lanes separate so your product reaches the right room.
Time from booking to post
Single posts: 5 to 7 business days from approved brief to live. Monthly packages: scheduled across the month on confirmation.
