Publicit Raises €700K to Crack Open Programmatic for SMBs

Think of the open programmatic market the way you'd think of a regional motorway network where two private companies own the only two motorways anyone actually drives on. Everyone else, the connected TV billboards, the digital audio stations, the local press, they exist, but the on-ramps are guarded by toll booths, agency middlemen, and minimum-spend gates. A small Barcelona team just raised money to build a new on-ramp.

The pitch is straightforward, the execution is the hard bit. And as anyone who has ever stared at an OpenRTB auction log at 2am can tell you, "milliseconds" is doing a lot of heavy lifting in any ad-tech pitch deck.

What Happened

As Tech.eu reported, Barcelona-based Publicit has closed a €700,000 pre-seed round co-led by BStartup Banco Sabadell and Successful Fund, with AticcoLab and a clutch of Spanish tech and media angels filling out the cap table.

The company was founded by Gabriel García Asensio, a former CERN engineer, alongside Andrés Buendía and Jordi Orteu. That CERN line matters more than it sounds. People who've shipped systems at particle-physics scale tend to have very particular opinions about latency, throughput, and what counts as a real-time pipeline. We'll come back to that.

The product itself is a self-service advertising infrastructure aimed squarely at small and medium-sized businesses. It bundles connected TV, out-of-home, digital audio, radio, and local press into a single interface, with no minimum spend. On top of that sits an AI-powered media planning layer that can, according to the company, autonomously plan and activate campaigns. Under the bonnet, Publicit has built its own European bidding infrastructure that processes auctions in milliseconds and applies AI-based optimisation during delivery.

The money will go where pre-seed money always goes: more infrastructure, more AI, and pushing the SMB self-serve story harder. The interesting bit isn't the cheque size, which is modest by ad-tech standards. It's the architectural ambition tucked inside a €700K round.

Technical Anatomy

Let's get into the guts of it. To do what Publicit claims, you need three layers, and each is its own headache.

First, the supply integrations. Connected TV inventory in Europe alone is a patchwork of broadcaster sales houses, SSPs, and direct deals. Out-of-home is worse, half the DOOH inventory is still booked by humans on spreadsheets. Digital audio has Spotify and a long tail. Local press is largely allergic to programmatic anything. Unifying all of that behind a single interface means writing adapters for wildly different protocols, some of which are vaguely OpenRTB-compliant and some of which are a phone call and a PDF.

Second, the bidder. Building your own European bidding infrastructure is a serious commitment. Real-time bidding gives you somewhere between 80 and 120 milliseconds to receive a bid request, decode it, evaluate it against budget pacing, frequency caps, brand safety, and an ML model, then return a price. At SMB volumes that's actually a tractable problem. Scale it to enterprise traffic and you're suddenly arguing about kernel bypass and NUMA pinning. Starting at the SMB end is a smart way to learn the system before the load curve becomes punishing.

Third, the planner. The autonomous media planning piece is where the AI claim has to deliver. There's a meaningful gap between "an LLM suggests a channel mix" and "a system that actually allocates budget across CTV, DOOH and audio based on observed campaign signal and reallocates mid-flight." The first is a wrapper. The second is an actual product. Which one Publicit ships will define whether this is a real platform or a clever onboarding flow over someone else's DSP.

The boring bit nobody talks about: identity. Post-cookie, cross-channel measurement is the part where it all falls over. Privacy Sandbox's attribution reporting is one piece, but CTV and DOOH have their own measurement primitives. Stitching that into a coherent SMB-friendly dashboard is non-trivial.

Who Gets Burned

The obvious targets are the small and mid-market media agencies who currently make their margin precisely because programmatic CTV and DOOH are too fiddly for an SMB to touch directly. If Publicit's self-serve flow actually works, that "we'll handle the agency layer" pitch loses its strongest justification. The agencies that survive will be the ones doing creative and strategy, not the ones charging a markup to push buttons.

The second category exposed is the long list of mid-tier DSPs that have spent a decade positioning themselves as "the alternative to Google and Meta" while quietly requiring €10K minimum monthly spends and an onboarding call. A no-minimum, single-interface competitor with an opinionated AI planner is a direct shot at that segment, at least in Iberia and likely across southern Europe over the next year.

The less obvious group: incumbent SSPs and inventory aggregators who've gotten comfortable selling premium CTV and DOOH only to enterprise buyers. If Publicit aggregates SMB demand effectively, those SSPs suddenly have to decide whether to integrate or compete. Most will integrate, which is fine for Publicit and uncomfortable for anyone whose business model assumes the SMB segment stays locked out.

My take on the next 90 days: regional CTV broadcasters in Spain will be the first to test integrations, because incremental SMB demand on otherwise unsold connected TV inventory is free money. DOOH will lag because the inventory side genuinely isn't ready. The Google and Meta giants, meanwhile, won't notice for a long time, which is exactly the window a pre-seed startup needs.

Playbook for Performance Marketing

For performance marketers and traffic leads reading this, here's the practical bit.

If you're running SMB or mid-market campaigns and you've been parked in the Google Ads API and Meta Marketing API for the last five years, this is a reminder that channel diversification is finally becoming operationally cheap. You don't need to wait for Publicit specifically. The whole category is moving. Start by mapping what percentage of your spend currently sits in walled gardens versus everything else. If the answer is 95/5, you have concentration risk that a single algorithm change can wipe out.

Second, run a small CTV test this quarter, even if it's clumsy. The measurement gap between walled-garden attribution and open-web attribution is closing, but the only way to build internal muscle is to actually run campaigns and argue about the numbers. Treat it as learning spend, not performance spend.

Third, get sceptical about "AI media planner" claims, including Publicit's. Ask three questions: what signal does it optimise on, how fast does it reallocate, and can you see the decision log. If any of those three answers are hand-wavy, you're looking at a wrapper.

Fourth, if you operate in iGaming, fintech, or any vertical where Google and Meta policy can yank your account on a Tuesday afternoon, omnichannel self-serve isn't a nice-to-have, it's an insurance policy. Build the relationships now.

Key Takeaways

• Publicit closed €700K pre-seed co-led by BStartup Banco Sabadell and Successful Fund, with AticcoLab and Spanish angels participating, to build a self-serve omnichannel ad platform for SMBs.
• The technical bet is a proprietary European bidding stack plus an AI media planner covering connected TV, out-of-home, digital audio, radio, and local press through one interface with no minimum spend.
• The competitive squeeze lands hardest on mid-market agencies and mid-tier DSPs whose value prop depends on programmatic complexity staying expensive for smaller buyers.
• Performance teams should treat this as a signal to actually test non-walled-garden channels this quarter, even at small budgets, to build measurement muscle before the category matures.
• Back to the motorway: a single €700K on-ramp doesn't break the Google-Meta toll network, but if enough of these on-ramps get built in parallel across Europe, the duopoly stops being the only road in town.
