Why they're on the list

Her real captions map almost one-to-one onto Gray Matters' target conditions: "10 sinais de BIPOLARIDADE que costumam passar despercebidos antes dos 25 anos," a carousel on lithium-level monitoring, and a post on ADHD medication's limits ("A medicação melhorou sua atenção... Mas ainda adia tarefas. Esquece compromissos."). That last post is a natural, honest bridge into "medication isn't the whole answer, a personalised non-pharmacological complement exists," the exact message the brief wants. Her tone is measured and clinical, no clickbait, the closest match in the pool to "Quiet Luxury." Her bio-link funnel (a WhatsApp community and course for other psychologists) is B2B, so it won't compete with a Gray Matters partnership.

Flags

Momentum and production scores above are conservative estimates, her clip sample returned no transcribable speech or exceeded the transcription tool's limit, so this judgment rests on caption text rather than a verified video transcript; recommend a manual watch of 1-2 Reels before final approval. Her recent format skews toward carousels over Reels, the brief's mixed-format ask should be written into her brief explicitly. Her PhD credential is stated, not independently verified in this session.

How to brief them

Have her bridge her existing ADHD-medication-limits theme into an introduction of neurofeedback as a science-backed, personalised, medication-free complement, not a replacement for psychiatric care. Require at least one Reel and one Stories sequence. Portuguese, explicit "Gray Matters Brasil" mention, accurate qEEG framing.

Why they're on the list

Directly on-topic for cognitive performance, the largest and most engaged audience in the pool (his top recent Reel drew 228k likes on 135k followers). A verified transcript on children's screen time cited a real University of Arizona study on the show Daniel Tiger accurately and calmly, describing himself as "médico pós-graduado em neurociência da alta performance," a real, checkable credential.

Flags

Real tone/aesthetic mismatch with "Quiet Luxury" — his default register leans into clickbait, all-caps hooks, and one real caption stereotypes women ("Se você não dorme direito e acorda mais bravo que mulher na TPM..."). A separate real caption overclaims: "Esse é o caminho neurocientificamente comprovado para evitar ter Alzheimer," exactly the kind of overstated claim the brief's "factually accurate" mandate rules out. At this reach, his rate is likely to sit at or above a lean sub-$10k budget once 6-month paid-amplification usage is priced in, unconfirmed, check directly.

How to brief them

Insist on line-by-line script pre-approval to strip absolute/overclaiming language and any stereotyping humor, and steer him toward his calmer, source-cited register (as in the Daniel Tiger video). Confirm his rate card against budget before any offer.

Why they're on the list

Her single most-viewed reel (1,079,921 plays, 89,452 likes) is a substantive, clinically grounded piece on emotional regulation, naming concrete evidence-based techniques and closing with her real CRP license number. Reach is consistently massive relative to her follower base across every sampled reel (400K-1M+ plays), a real, engaged audience actively seeking help with anxiety.

Flags

Her positioning is "psicóloga de relacionamentos" first, general anxiety second, a mild scope tangent. Her format leans on trending pop-audio hooks and a casual, meme-adjacent comment culture, more mass-market than the brief's "Quiet Luxury" sophistication, needs explicit creative direction to tone down.

How to brief them

Brief her specifically on anxiety and non-pharmacological self-regulation (not relationships), and ask for a calmer, more restrained visual/audio treatment than her usual trend-audio format.

Why they're on the list

Of the whole pool, his written voice is the closest match to "Quiet Luxury," reflective, literary, unhurried. Real caption: "Talvez um dos grandes problemas da vida moderna seja que aprendemos a anestesiar aquilo que deveríamos aprender a sentir." A genuine, independently-verifiable academic/clinical credential supports "The Expert" archetype well.

Flags

his top-engagement transcript ends with an explicit pitch for his own paid "Método INSIDELIC" program, and the same transcript frames talk-only therapy as comparatively shallow versus his own method. A Gray Matters post risks being a secondary mention behind his own CTA unless the contract requires a dedicated, exclusive piece with no cross-promotion of Método INSIDELIC, Cingulo, or Sensing. Not Instagram-verified despite his real academic profile.

How to brief them

Contract must require an exclusive post/Reel series, no mention or link to his own programs or apps, pre-approval of scripts, "Gray Matters Brasil" named explicitly and early so it isn't overshadowed by his personal brand.

Why they're on the list

One of Brazil's most credentialed, recognized voices for evidence-based psychology, PhD from USP, founder of the Institute for Evidence-Based Psychology, 2025 Jabuti Prize finalist. His measured, credentialed, unhurried tone is a genuine "Quiet Luxury" match.

Flags

His content and stated mission target other psychologists, not consumers seeking treatment, so his audience likely skews toward mental-health professionals and students rather than the general public who would book a neurofeedback session. Real audience-fit risk worth testing before committing budget.

How to brief them

Brief him for a direct-to-consumer piece specifically, not his usual practitioner-facing format, explaining neurofeedback and qEEG mapping to patients in the same evidence-based register he uses with other psychologists.

Why they're on the list

Genuinely Brasília-based, a real geographic match to the clinic's physical location. Her most-engaged reel ("Minha rotina diária como psiquiatra") is a first-person, unhurried walkthrough of breathing exercises to activate the parasympathetic nervous system, a midday mental body-scan, gratitude journaling, and sleep hygiene, no clickbait, no overclaiming, the closest tonal match to "Quiet Luxury" found in this whole search. Directly touches two of Gray Matters' own core themes: nervous-system regulation and sleep.

Flags

she runs her own psychiatry practice (Orta Saúde Mental, linked in bio). Not a neurofeedback competitor, but the Gray Matters piece should be scripted so it doesn't read as a plug for her own practice instead.

How to brief them

Brief her to extend her existing nervous-system-regulation and sleep-hygiene content into an explanation of qEEG-guided neurofeedback as a complementary, non-pharmacological option, in the same calm first-person register as her routine video. Require explicit "Gray Matters Brasil" naming, not folded into her own practice's branding.

Why they're on the list

The strongest genuinely Brasília-anchored, large audience in the entire pool, real, verified, consistent 500-4,000 likes per post. Her own narrative directly names burnout and reconnection: "Teve um tempo em que eu achava que estava vivendo o certo: trabalhava muito, ganhava bem... mas por dentro eu estava esgotada." A featured guest in one of her reels says moving toward nature made his life change "por completo." This is the "aproveitar Brasília, relaxar" angle Duda asked to add, real content, real local audience, not a national-reach expert.

Flags

she runs her own commercial farm-stay tourism venue (Vida Rural Brasília) and her bio-link funnel drives bookings to it. Same issue as Diogo Lara: without contract language, a Gray Matters piece risks reading as an ad for her own farm rather than for the clinic. No neurofeedback/clinical conflict, this is a commercial-attention conflict, not a competitor conflict. FLAG — narrative distance: she is not a mental-health or neuroscience voice. Bridging from "slow down in nature" to the brief's specific mandatories (qEEG, non-pharmacological treatment, "Gray Matters Brasil" named explicitly) needs real scripting, this is not content she'd produce organically.

How to brief them

Script the piece tightly: her own burnout story as the hook, then an explicit, named bridge to Gray Matters' qEEG-based neurofeedback as a science-backed way to get the same nervous-system reset she found in nature. Contract must keep the piece from cross-promoting her own farm-stay bookings.

Why they're on the list

Genuinely strong scientific credibility (Mackenzie/Harvard, SBNM Psychology committee coordinator) and content that is explicitly evidence-based: a recent post on "O Impacto da Depressão no Cérebro," citing a real 10-year longitudinal study, and a post on adapting CBT for neurodivergent patients "sem perder o rigor científico." Still active as of this run (re-verified 2026-09-28). Originally deprioritized in the 09/10 study only for being too small for a single-pick, not for any content or credibility issue, brought back in now that the brief covers a full list.

Flags

Small reach (3,436 followers) and low absolute engagement (13-321 likes per post), would need pairing with paid amplification to matter at scale, a genuine stretch pick, not a proven-audience pick. Some of her audience likely skews toward peer psychologists (via her "New Minds Psychologists Club"), not just consumers.

How to brief them

Use her as a credibility-anchor supplementary voice rather than the primary cast, brief her to apply her existing depression/neuroscience rigor directly to explaining qEEG-based neurofeedback.

Why they're on the list

Her stated identity, explaining neuroscience simply and grounded in evidence, is a near-literal match for Gray Matters' "demystify neurofeedback" objective. Nothing in her sampled content contradicts that positioning.

Flags

Very small reach (663-2,000 plays per reel), would need pairing with paid amplification to matter at all, a genuine reach gamble.

How to brief them

If used, brief her as a low-cost, high-authenticity supplementary voice rather than the primary cast.

Why they're on the list

By far the largest raw reach found relative to this tier (up to 6.48M plays on a single reel), and her bio claims a direct anxiety/self-esteem specialization.

Flags

Not recommended as a primary pick without further review. Her actual top-performing content is a generic inspirational quote about self-worth, not clinical or anxiety-specific, and the sampled comments are almost entirely generic reaction emoji, not engagement with clinical substance, a pattern consistent with viral-quote content rather than a trusted clinical-authority relationship. This is a real risk for a brand-sentiment-and-authority objective.

How to brief them

Only pursue after reviewing 3-5 more posts directly to confirm she has genuine clinical-education content beyond viral quote cards; if she does, brief her narrowly on non-pharmacological anxiety treatment.
