A technical operation that chose one problem: being the answer.
destaque.aiis a Portuguese GEO software company based in Lisbon. We measure brands’ presence in the answers of AI engines with our own technology, and carry out the work that changes it.
Our own software. Our own data. Our own method.
destaque.ai is a Portuguese GEO (Generative Engine Optimization) software company: we measure and build brand presence in AI answers, the layer where buying decisions now happen. We built Periscopy: it puts hundreds of real buyer questions to 11 AI engines and surfaces every week, stores every answer, extracts who gets cited, why and with which sources, and turns that into a plan with proof action by action. The models are bought from the market and we say so; what is ours is the software that questions them, the method that reads the answers, and the history that accumulates. Every week of operation grows a dataset you cannot buy ready-made, and it is on that data that we model the market. Based in Lisbon, it works with brands across Portugal, including Porto.
We are not a marketing agency that added AI to its portfolio: measurement comes first, and the plan comes ready to execute, with written fixes, briefs and proof action by action, built on solid experience in technical and local SEO. Agencies tell you what they think; we show you what the engines answer about your brand, week after week.
For any brand that lives on being found.
SaaS, software, platforms, websites, e-commerce, online services.
Appearing when someone asks ChatGPT, Claude or Perplexity about your category. On-site work (technical SEO, schema, extractable content) and off-site work (topical authority, mentions in the sources the models read).
Clinics, restaurants, tourism, retail, local services.
Appearing in local answers inside Google AI Mode and in assistant recommendations for your area. Google Business Profile, reviews, consistent name and address, local directories, geographic signals on the site.
The mechanics differ; the principle is the same: be citable by the models before the click ever happens.
GEO software built in Portugal, for the Portuguese market.
The tools that exist are international and think in English. What exists in Portugal are agencies, not products. It is not a question of flags, it is a question of reading: when an assistant answers about private hospitals in Porto and pulls six Brazilian sources, a foreign tool records coverage in Portuguese. We know that is a gap, and we know which pages fill it. That difference repeats every week, in every category, and it cannot be learned from a distance.
A Portuguese buyer does not type "best CRM software". They type "melhor programa de faturação para pequenas empresas". Translating the question changes the answer, and you end up measuring something else.
We know which pages decide the answers here: the national press, the forums where each category is discussed, the directories nobody outside knows. We monitor those sources, and when we find a new one the models use, it goes into the monitoring.
What counts is not the global average, it is where you stand against whoever competes for the same customer in Portugal. We have that base because we built it, audit by audit.

Half the funnel moved.
Decision-makers now research suppliers in ChatGPT, Claude, Gemini and Perplexity. Most companies kept optimising for Google’s results page.
The international platforms measure well. What they lack is native command of European Portuguese, a local presence that is accountable, and someone who knows what to do with the data. A dashboard without execution is a problem, not a solution.
Four rules that are not negotiable.
