Best Marketing Agencies in São Paulo (2026)

Introduction

São Paulo is Brazil’s main base for performance, data and CRM marketing, and the six agencies below each run a verified office or operation in Greater São Paulo in 2026. They range from a WPP-backed experience agency in Vila Leopoldina to an SEO specialist on Avenida Berrini.

Much of the city’s recent marketing work has moved towards commerce. Retail media, marketplace search and social commerce now sit next to paid search and CRM in most briefs, helped by TikTok Shop’s launch in Brazil in 2025 and by large advertisers such as Mondelēz moving their performance, CRM and retail media operations to specialist agencies. The market is also consolidating: WBP bought half of the performance agency Leads For You in January 2026, and the old Raccoon.Monks address now points to Monks’ Portuguese site.

Every firm here was checked against its own site or Brazilian trade press for a São Paulo presence in 2026. Idea-led creative shops and network advertising agencies are covered on their own pages. The list is unranked and shorter than most in this series, because we only included firms we could verify.

The best marketing agencies in São Paulo

1. Monks Brasil

S4 Capital · Pinheiros · monks.com

Monks describes itself as a global content, data, media and technology company, and it is part of the S4 Capital group. Its São Paulo office sits on Rua Girassol in Pinheiros, with further Brazilian offices in São Carlos and in Votorantim near Sorocaba.

The Brazilian offer covers branding, social, media, data, experience, e-commerce, platforms and AI, packaged into solutions such as media acceleration and marketing orchestration. The former Raccoon.Monks site now redirects to Monks’ Portuguese pages, so ask which Brazilian office and team will run your account.

2. Jüssi

WPP · Vila Leopoldina · jussi.com.br

Jüssi calls itself “The Experience Agency” and works from WPP’s São Paulo campus on Avenida Mofarrej. Its practice is split into digital commerce (conversion, retail media and TikTok Shop), media intelligence (programmatic and lead generation), data-led CRM and loyalty, and digital experience, SEO and growth.

Recent work includes Lacta’s Easter campaign, Trident at Carnaval and Casas Bahia’s “Caminhão da Dedicação”. Jüssi was the only agency to win in the Retail Media category at the MMA Smarties 2025, and it has also won at RankMyAds (for Youse) and the TikTok Ad Awards Brasil.

3. Cadastra

Independent · São Paulo · cadastra.com

Cadastra started as a search engine marketing pioneer 26 years ago and now describes itself as a growth and digital performance leader in Latin America. It has more than 900 staff and over 300 clients, with hybrid teams in São Paulo and Porto Alegre, and works through centres of excellence that run from media and CRM to data, AI, commerce and cloud.

Clients include Unilever, Ambev, Grupo Boticário, Reckitt, Samsung and Suzano, whose Amazon retail SEO case appeared in February 2026. In late 2025 Google’s AI Assessment named Cadastra among its most AI-mature agency partners, VTEX gave it a Most Valuable Partner award, and CEO Thiago Bacchin was placed in the iBest 2025 Top 20 for digital advertising.

4. NeoPerformance

Independent · São Paulo · neoperformance.com.br

NeoPerformance is a performance marketing agency with its main operation in São Paulo and further offices in Mexico and the United States. It runs campaigns through NeoDash, its own data platform, and reported growth of almost 40% in the second half of 2025.

In July 2025 Mondelēz Brasil appointed it to lead performance media, CRM, B2C and B2B e-commerce and retail media for brands such as Lacta, Bis, Oreo and Trident, working alongside the client’s creative agencies. It also handles Mercado Livre in Mexico, and in February 2026 it hired senior directors from BRF, DM9 and McCann.

5. Agência Mestre

Independent · Berrini · agenciamestre.com

Agência Mestre was founded in 2008 and works from Avenida Engenheiro Luiz Carlos Berrini in the south of the city. Search is its core: SEO, technical audits, site migrations and, more recently, generative engine optimisation for visibility in AI answers.

Around that it runs inbound marketing, Google, Meta and ChatGPT ads, analytics, conversion optimisation, CRM implementation and WhatsApp automation. Clients include Sympla, Duratex, Amanco, Quero Passagem and Unimed Campinas. It suits mid-sized brands that want search and paid media handled by one team.

6. WBP

Independent · São Caetano do Sul · wbp.com.br

WBP is a communication and marketing agency in São Caetano do Sul, in the ABC region of Greater São Paulo. It sits within the WBP Group, which also includes Metrix for data and business intelligence, plus a business club and an events arm. The agency employs around 150 people.

In January 2026 WBP acquired 50% of the performance agency Leads For You, taking its client base from 150 to 260, and set itself a target of 150% growth for the year. It also added offline advertising and press relations teams, so it can cover a wider brief than most performance shops.

What to look for in a São Paulo marketing agency

Start with where the agency’s strength sits in the funnel. Some of the firms above began in search or paid media and added CRM and data later; others grew from network experience agencies and bring commerce and creative under one roof. Ask to see recent results in the channel that matters most to you, whether that is retail media on Mercado Livre and Amazon, lead generation or retention.

Check the data setup early. Agencies such as NeoPerformance and Cadastra run their own platforms or analytics layers, and it is worth agreeing who owns the dashboards, the first-party data and the account access if the relationship ends. Brazil’s LGPD applies to CRM work, so involve your own legal team in decisions about consent and data handling.

Ask who will work on your account and where they sit. Many São Paulo agencies run hybrid teams spread across several Brazilian cities, and some serve Mexico and the wider region from São Paulo. Named people, and a clear line between strategy and execution, make a difference over a long retainer.

Finally, look at how the agency handles reporting, briefs and approvals day to day. Performance work produces a steady flow of creative variants, landing pages, reports and call notes. Agencies with one place for the latest files, and a clear record of what the client approved, spend less time chasing versions across email and WhatsApp.

How Fabric helps marketing agency teams

Fabric gives a marketing agency one workspace for files, client knowledge and AI search. The agency setup works well for teams running several accounts at once, with one space per client for briefs, media plans, creative variants and reports. There are specific notes for performance marketing teams and SEO agencies.

Search works by meaning across documents, PDFs, images and transcribed recordings, as well as connected apps such as Google Drive, Notion and Gmail. A strategist can find last quarter’s retail media report or a client’s tone-of-voice notes without remembering the file name. Creative files sit in Fabric’s cloud drive, which streams them on demand rather than filling local disks.

For client reporting, any file or folder can be published as a web page and updated by editing the source. Link analytics shows when each named recipient opened a report or pitch and how long they spent with it. Clients can leave threaded comments through a shared link without creating an account. Commenters can also leave timestamped comments on video and draw on any video frame.

On Team plans, self-writing docs keep a page for each client up to date from meetings, Slack and the workspace, covering decisions, deliverables and open items. AI meeting notes record calls without a bot and merge the notes with the transcript.

Link analytics and password protection are included on Pro and Team plans, and self-writing docs on Team plans. See plans for teams.
