8 Marketing Agencies Worth Following on Instagram

Eight marketing and PR agencies stand out on Instagram for how they show culture, process and client work: TBWA, Huge, Mother London, Wolff Olins, Red Antler, Skirt PR, The Martin Agency and SPARK. Trade roundups from 2015 to 2023 highlighted each one. Follower counts change constantly, so check each account for its current numbers before you follow.

Originally published June 2017. Rewritten October 12, 2026. Handles and descriptions come from HubSpot's August 2023 update of its agency roundup and from EPR's 2017 reporting.

Which marketing agencies are worth following on Instagram?

The eight agencies below were chosen because published roundups describe a clear editorial approach on each account, not because of follower counts. The table lists the handle, what the feed shows and where the description comes from.

Agency	Handle	What the feed shows	Source
TBWA	@tbwa	The network's global account. EPR's 2017 reporting found it handed to a different network office each week	EPR 2017; TBWA About page
Huge	@hugeinc	High-quality photography, graphic design inspiration and office snapshots	HubSpot, 2023
Mother London	@motherlondon	A different creative takes over the account each week	HubSpot, 2023
Wolff Olins	@wolffolins	Design inspiration and behind-the-scenes snaps of its creative strategy work	HubSpot, 2023
Red Antler	@redantler	Design inspiration, office culture and work with startups	HubSpot, 2023
Skirt PR	@skirtpr	Boutique openings, parties and design-led event photography	HubSpot, 2023
The Martin Agency	@martinagency	Employee-level office life, throwback ads and the #martindoes hashtag	HubSpot, 2023; EPR 2017
SPARK	@sparkbrand	Behind-the-scenes shoots and illustrations for clients including Hilton, Visit Florida and The Dalí Museum	HubSpot, 2023

What does TBWA do differently on Instagram?

TBWA, the Omnicom-backed agency collective, runs its main Instagram account as a shared stage for its offices. TBWA describes itself on its own site as a collective of more than 11,000 creative minds across agencies in over 40 countries, and EPR's 2017 reporting found the global account rotated between network offices so that posts changed from week to week.

The lesson for any multi-office firm is structural: a rotating owner keeps the feed varied and gives local teams a reason to contribute. The risk is inconsistency, so rotation works best with a shared editorial rule.

Which agencies use Instagram to show their people?

Huge, Mother London and The Martin Agency use Instagram to show who works at the agency. HubSpot describes Huge's feed as a mix of high-quality photography, design inspiration and office antics, and says Mother London hands the account to a different creative each week.

The Martin Agency's feed, per HubSpot, gives an intimate look at how employees at one of the world's most influential agencies work day to day, alongside the agency's work for clients such as Geico, Chevrolet and Oreos. For recruiting, a people-first feed answers a question candidates ask before they apply: what is it like to work here?

Which agencies use Instagram to show their craft?

Wolff Olins, Red Antler and SPARK use Instagram to show design and production work. HubSpot says Wolff Olins shares design inspiration and behind-the-scenes snaps, Red Antler posts design inspiration and work with startups, and SPARK takes followers behind the scenes and on location as it shoots and edits ads for brands such as Hilton, Visit Florida and The Dalí Museum.

For a buyer, craft-led feeds work as a free portfolio. They show process, not only finished campaigns, which is hard to fake in a pitch deck.

How does a PR firm use Instagram?

A PR firm uses Instagram to show relationships and events, because the work is less visual than design. Skirt PR is the example: HubSpot describes a feed built around boutique openings, cafe gatherings and celebrations, and EPR's 2017 profile identified Skirt as a Chicago boutique specializing in event management, public relations and social media.

What should you look for in an agency's Instagram account?

Judge an agency's account on the signals below, because they show how the agency works. These are criteria EPR applies, not rankings.

Signal	What it tells you	Example in this list
Posting rhythm	Whether someone owns the feed or it is an afterthought	Mother London's weekly takeover
Client work shown with context	Whether the agency can explain its thinking, not only show results	SPARK's behind-the-scenes shoots
People on screen	Culture and retention, which affect the team a client actually gets	The Martin Agency's employee-level posts
Design quality	Taste, which is the product for creative and branding firms	Huge, Wolff Olins, Red Antler
Link to a business result	Whether Instagram supports hiring, pitches or clients	Skirt PR's event-driven feed

Conclusion

The agencies worth following share one habit: each gives its Instagram feed a clear job, whether that is showing people, process or events. Pick the account whose job matches what you need to learn, and compare it against your own feed.
