Best Social Media Agencies in São Paulo (2026)

Introduction

São Paulo is where most of Brazil’s social media and influencer marketing budgets are planned and spent, and the seven agencies below are a good place to start a shortlist. They range from creator-marketing pioneers with their own technology to social-first shops that run a brand’s channels day to day.

Brazil’s creator market kept growing and professionalising through 2025 and 2026. TikTok Shop launched in the country in May 2025, and Instagram brought Live Video Ads to Brazil in October 2026. Influence work is also moving into the mainstream of account reviews: in August 2026 Meio & Mensagem reported Vivo naming a dedicated brand relations and influence partner, and in September 2026 Grupo WE took a stake in the social-first agency WT.AG, which earns most of its revenue in São Paulo.

Every agency here has a São Paulo office shown on its own site or in trade coverage. We favoured social and creator specialists over full-service networks, which appear on our other São Paulo lists. The list is unranked, as the right fit depends on whether you need creator campaigns, channel management or both.

The best social media agencies in São Paulo

1. Squid

Acquired by Locaweb · Pinheiros · squid.com.br

Squid has worked in influencer marketing since 2014 and describes itself as one of the first Brazilian companies in the field. It runs as a technology company as much as an agency, with a community of more than 300,000 certified creators and its own tools for audited data, creator approval, contracts, payments and real-time reporting. The web services group Locaweb acquired the business.

Brand work covers planning and market intelligence, creator curation, seeding, production and paid amplification. Reckitt chose Squid as its exclusive influence-marketing partner and Wella Company appointed it after a competitive process; earlier clients include Grupo Boticário, Bradesco and Unilever. Its office is on Rua Cardeal Arcoverde in Pinheiros.

2. Mynd

Independent · Itaim Bibi · mynd8.com.br

Mynd calls itself the largest digital culture, music, talent and influencer marketing agency in Brazil. It combines talent management with brand campaigns, which gives it unusual access to musicians and creators, and it has its own events such as Mynd Talks, CRE8TRS.day and Potências Day, a forum on Black professionals in advertising.

Campaign work includes iFood, where Mynd turned a viral meme comparing Luísa Sonza and Erling Haaland into earned media, plus creator projects for Eudora and Giovanna Baby. Its Rock in Rio programme reported 103 million users reached and 839 million impressions. The agency has also taken its influencer practice to Portugal. The São Paulo office is in Itaim Bibi.

3. WT.AG

Independent, with a minority stake held by Grupo WE · Vila Olímpia · wt.ag

WT.AG is a social-first agency built around a model it calls Social Branding, which joins data, content, creative and media. Lucas Feltes founded it in Novo Hamburgo in 2003, and it opened in São Paulo in 2019. About 85% of its revenue now comes from the São Paulo market, and it has more than 130 people across the two cities.

In September 2026 Grupo WE bought an undisclosed stake, with Feltes staying on as CEO and the agency keeping its own structure and client relationships. Clients include Magalu, Multiplan, Calvin Klein, Grupo Silvio Santos, Sicredi, Grupo Fleury and Odontoprev. Recent creator work includes a Magalu campaign with Fiuk and a Firestone campaign with Caio Collet.

4. Spark

Independent · São Paulo · createspark.com.br

Spark is an influencer marketing specialist founded in the mid-2010s by Raphael Pinho (co-CEO) and Rafael Coca. Its headquarters is in São Paulo, and it opened a Rio de Janeiro office to serve L’Oréal Groupe. Clients are served through dedicated squads, branded Skuad, that combine production, strategy and data intelligence for always-on creator programmes.

In June 2025 Spark won the influencer marketing account for RD Saúde’s Raia and Drogasil brands after a pitch, and it was the official partner for influencer projects at The Town 2025 festival. Other clients include PepsiCo (Toddy, Toddynho, Kero Coco and Quaker) and Pierre Fabre (Avène). Festival work is a strength: it ran 15 activations for 10 brands across Rock in Rio 2024 and Lollapalooza Brasil 2025.

5. Ampfy

Part of the Biosphera.ntwk group · Vila Madalena · ampfy.com

Ampfy was founded in 2011 as a digital-native agency and has grown into an integrated shop of more than 240 people, headquartered on Rua Girassol in Vila Madalena. It won a Caboré in the marketing services category in 2016 and ranked first among Brazilian agencies for client ratings in AgencyScope’s 2023 to 2024 study. It sits within the Biosphera.ntwk ecosystem.

Ampfy is the broadest firm on this list and suits brands that want social and creator work planned alongside wider campaigns. In May 2026 it won Flying Fish’s business in Brazil after a pitch, and it also leads communication for BASF’s agricultural solutions in the country. Other clients include Krispy Kreme, Dr. Oetker, Grupo Piracanjuba and Bauducco, whose packaging “hack” earned the agency its first CLIO silver.

6. Byoung

Independent · Bela Vista · b-young.me

Byoung (B-Young Social Media Co.) is a dedicated social media agency founded in 2010 and led by CEO André de Alencar. Its services cover social strategy and consulting, social listening, channel management, influencer marketing, social ads and digital customer service, so it can take on the full running of a brand’s channels.

Its AliExpress work includes the TikTok campaign #TipoPechincha, which the agency reports passed two billion views, and the #DuetoSurpresaAli creator activation. It runs the full social operation for Volkswagen Financial Services, all digital marketing and content for Bioré in Brazil, and social channels for History Channel. The office is on Avenida Brigadeiro Luís Antônio in Bela Vista.

7. Celebryts

Independent · Jardins · celebryts.com

Celebryts started as a startup connecting YouTubers with advertisers and now works as an influencer platform with a managed service on top. Its database covers more than 50,000 vetted creators across micro, macro and mega tiers, and the tools handle search, proposals, gifting outreach and tracking of sign-ups and sales from each campaign.

Brands can run campaigns themselves or hand over the whole process, from creative to results. The company says more than 2,000 brands and agencies have used it, with names such as P&G, Nestlé, L’Oréal, Mercado Livre and Netshoes on its site. It suits teams that want a lot of micro-creator reach with clear tracking. The office is on Rua Maria Carolina in Jardim Paulistano.

What to look for in a São Paulo social media agency

Decide first whether you need creator campaigns, channel management or both. Squid, Spark and Celebryts are built around influencer work, with their own creator databases and tools. Byoung and WT.AG are closer to running a brand’s channels every day. Mynd sits between the two, with its talent and music roster as the draw.

Ask how creators are chosen and checked: audience data, follower authenticity, brand-safety history and contract terms. Several agencies here have built their own technology for this. Ask to see the reporting a client receives, and how results are measured beyond reach and impressions, for example sales, sign-ups or brand lift.

Look closely at ownership and team structure. São Paulo’s social agencies have been consolidating, with stakes taken by groups such as Grupo WE, Biosphera.ntwk and Locaweb. Ownership can bring shared data and back-office scale. It is still worth asking who will run your account day to day, and whether the agency has squads dedicated to single clients.

Finally, ask how the agency handles the volume. Always-on programmes produce hundreds of posts, videos and creator drafts a month, each needing brand, legal and sometimes medical or financial sign-off. Agencies with one place for briefs, drafts and approvals, and a clear record of who approved what, cope better when a campaign runs across dozens of creators.

How Fabric helps social media agency teams

Fabric gives a social team one workspace for creator content, client feedback and campaign knowledge, with AI search across all of it. The setup for social content agencies is built around one space per client, holding briefs, creator lists, drafts and reports together.

Video drafts and raw creator footage sit in Fabric’s cloud drive, which streams files on demand so they take no local disk space. Uploaded video and audio is transcribed and becomes searchable, so a strategist can find the clip where a creator mentions the product and jump straight to that timestamp. Search works by meaning across documents, images and connected apps such as Google Drive and Notion.

Any folder can become a Kanban board whose cards are the files themselves, which suits a content calendar moving from brief to draft to approved. Clients and creators can leave threaded comments through a shared link without creating an account. Teammates and clients can leave feedback in the form of timestamped comments and even timestamped drawings on top of the video.

For reporting, a campaign folder can be published as a web page and shared with password protection. Link analytics shows when each named recipient opened it and how long they spent. On Team plans, self-writing docs can keep a page for each client up to date from meetings, Slack and the workspace.

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

Frequently asked questions

What is the best social media agency in São Paulo?

There is no single answer, as it depends on whether you need creator campaigns or channel management. For influencer programmes, Squid, Spark and Mynd have the longest track records. For running a brand’s channels, Byoung and WT.AG focus on day-to-day social operations.

What is the difference between a social media agency and an influencer marketing agency?

A social media agency usually runs a brand’s own channels: strategy, content, community management and social ads. An influencer marketing agency plans and manages paid work with creators. Many São Paulo agencies do both, but most lead with one.

How much does a social media agency in São Paulo cost?

Most agencies work on monthly retainers for always-on channel management and on project fees for creator campaigns, with creator fees and paid media billed on top. Ask for a breakdown that separates agency fees from creator and media costs.

Do São Paulo social agencies also produce video content?

Most produce short-form video for social channels, often with creators. For larger shoots, branded series or a steady flow of studio content, a dedicated production partner may suit better; see our list of content studios in São Paulo.

Which São Paulo agencies are best for TikTok?

Byoung’s #TipoPechincha campaign for AliExpress is one of the larger TikTok cases on this list, and Spark has run events on influencer campaigns for TikTok. With TikTok Shop live in Brazil since 2025, it is worth asking each agency how it links TikTok creator content to sales.
