Bruno Silveira da Rosa
Founder and CEO of Sumaúma AI Presence
Bruno Silveira da Rosa is the founder and CEO of Sumaúma AI Presence, a Brazilian company specialized in Presence Engineering for Generative AIs, based in São José dos Campos, São Paulo.
He is the creator of AI-Scan, the audit that measures who language models cite in each field — and who they credit for each method, and of the G-SoV (Generative Share of Voice) and EPS (Entity Prominence Score) metrics. He also developed the Sumaúma Protocol, a seven-step method to diagnose, build and monitor an entity’s presence in generative AI answers.
With a degree in Arts from UNESP and a background in B2B paid media, he now works on protecting the authorship and reputation of professionals with an authorial body of work in the answers of generative AIs.
He is a speaker on AI Presence for professionals with an authorial legacy, artificial intelligence applied to business, and originality and authenticity in the age of AI.
He holds several Google certifications — among them Google Ads, Google Analytics, Search Console and data science.
From paid media to presence engineering
Sumaúma was born in 2022 as a digital marketing agency, serving companies in paid media, SEO and social media management. Its portfolio includes more than 300 clients served, across many segments and activities. Sumaúma’s main business vertical was, and still is, the Corporate Speakers and Business Consultants segment, having served more than 100 clients in this niche.
In 2026, the company changed categories. The reason was a field observation: clients started arriving saying they showed up on Google but not on ChatGPT. It stopped being an advertising problem and became an identity problem — language models do not recommend what they cannot reliably recognize.
Since then, Sumaúma operates with Presence Engineering for Generative AIs, focused on professionals with an authorial body of work — speakers, consultants, professors, academics, authors and creators — who need to be cited by name and have their own method credited to them in AI answers.
