Choosing among the advertising agencies in Sofia is a decision about who will think, produce and place your message in Bulgaria. Under the EU rules on unfair commercial practices, which Bulgaria applies through its national Consumer Protection Act (current version published in State Gazette no. 87 of 24 September 2026, text consulted on kik-info.com), submitting or commissioning someone else to submit false consumer reviews or endorsements in order to promote products is an unfair commercial practice, and the maximum fine for widespread infringements is 4% of the trader's turnover in the preceding financial year in the Member State or Member States concerned. Bulgaria, as an EU member state, has to apply that rule, so an agency's method for reviews and influencers belongs in the choice.

Why does a local agency matter in Sofia?

A local agency matters because the work that makes a Bulgarian campaign effective happens in Sofia: Bulgarian-language copy, the outdoor sites and events of the city, and briefs that can be discussed face to face. According to the National Statistical Institute's final data on non-financial enterprises for 2024, published on 28 November 2025, 472253 non-financial enterprises in Bulgaria submitted an annual report for 2024, which is 2.1% more than the year before. Those companies are the pool of potential clients for every agency on this list. This is a count of businesses, not of advertising spend, which the agencies themselves rarely publish.

A Sofia address is not enough on its own, though. The question to answer is whether the people who will work on your brief are in Sofia, and that is what the ranking below tries to check.

What are buyers in Sofia afraid of?

Four fears come up when companies compare agencies in Sofia, and each one can be tested on the agency's own site and in a first call.

1. An address with no team behind it. A street address on a homepage does not prove that the people who will run your account work in Sofia. Ask for names and roles, and check that they are not only sales staff.

2. Work run from somewhere else. A network with offices in several cities can be an asset, but the account lead may sit in another city. Ask who makes the decisions on your account and where that person works.

3. Awards and numbers that cannot be checked. Phrases such as "international awards" or "500+ projects" are the agency's own words. Ask for the festival, the year and the client behind each claim.

4. Fake voices and reach without results. The EU rule above treats false endorsements as an unfair practice, and views are easy to show but hard to link to sales. Ask how reviewers and influencers are chosen and disclosed, and which result each campaign was built to move.

How did we rank these agencies?

Four criteria, fixed before we checked who meets them, and applied only to what each agency publishes about itself. Every homepage on this list was reread in November 2026, and this page is scheduled for review every 90 days.

1. Real presence in Sofia. An address, an office or a team stated on the agency's own site.

2. A multichannel advertising offer. Creative, media or advertising across several channels, not a single one.

3. Proof published on the site. Clients, campaigns, awards or figures, attributed to the agency.

4. A readable offer. Services listed and a direct way to get in touch.

What we deliberately did not do: we did not rank on self-descriptions such as "the best" or "the number one", which many sites use about themselves, and we did not use award counts or client numbers as scores, because they cannot be verified from outside. We also left out every agency whose site did not state a Sofia address, office or team, even when it works across Bulgaria.

The 10 best advertising agencies in Sofia

1. GOBOX

GOBOX is a full-service creative agency that describes itself as based in Sofia, working on content strategy, digital marketing, communications and branding. Its homepage lists five core strengths, creative and design, integrated communication, digital and social media, video production and distribution, and BTL and ambient, and states 15 years of experience.

Best for: brands in Sofia that want one agency for creative work, social media, video and activation. Ask for client references and for the method behind any result the agency quotes in the first call.

2. AdwayCreative

AdwayCreative presents itself as a digital marketing agency in Sofia, says it has been a trusted partner since 2007, and claims 18+ years of market experience. Its site states 250+ successful projects and 15+ international awards, and lists Google and social ads, web and e-commerce, UI/UX, video production, print and branding, and outdoor and indoor advertising. It says it has no mandatory minimum term.

Best for: companies that want performance advertising on Google and social platforms, combined with video and outdoor. The award count is the agency's own claim, so ask which festivals and years it refers to.

Its services are strategy and campaigns, brand development, TV commercials, and off and online events. Its achievements section lists two bronze awards at FARA 2024 and two finalist places at FARA 2019.

Best for: brands that want TV and campaign work from a team that says it prefers a few long-term partnerships to many projects. Ask how many accounts its team takes on before you commit to a calendar.

4. proof.

proof. describes itself as a creative agency based in Sofia, with a street address in the city published on its site. Its work page lists campaigns by channel, from ATL and strategy to social media, digital, and BTL and events.

5. AM Design

It covers web design, branding, print, promotional items, video and social media, and outdoor advertising, and states 500+ projects and 300+ clients.

6. Globe One Digital

Globe One Digital lists offices in Athens, Bucharest, Sofia and Belgrade. It describes itself as a digital marketing and consultancy agency, offering strategic vision, digital transformation, performance marketing and creative experiences. Its homepage states that it is ISO-certified and was among the Top 100 fastest-growing companies on the Inc. 5000 Europe list.

7. DigiStart

Best for: small and mid-sized businesses in Sofia, online shops and physical stores alike, that want search and social ads with a clear first step. The homepage has a 'successful example' section, but the case details are not in the text we read, so no figures are quoted here. Ask for the case data during the call.

8. Digital crew

9. The Locals

The Locals describes itself as a BTL and advertising agency in Bulgaria, with an office at 74-78 Hemus street in Sofia. Its homepage focuses on events, from festivals and brand activations to private events, and shows a list of clients.

Best for: brands that need events, activations and experiential work in Sofia. Ask for case studies and for the person who runs the media side.

10. DawnForge Studios

DawnForge Studios presents itself as a digital marketing and technology agency with one team in Sofia. It lists five services, including advertising on Meta, TikTok, YouTube and Google, SEO and AEO, custom websites and AI automation.

Best for: companies that want ads on Meta, TikTok, YouTube and Google handled by the same team that builds the site. Its scope is wide, so ask how much of the budget goes to each service.

The criteria below were chosen before checking who wins them, and each cell reflects what the agency publishes on its own site in November 2026. Where a site says nothing on a point, the cell reads "Not published", which means not found in the text we read, not that the service does not exist.

What should you check before signing?

Three questions separate a shortlist faster than any showreel, and each one answers one of the fears above.

1. Who will work on your account, and where do they sit? Ask for names and roles, and for the people in Sofia who will attend the briefs. A team that is hard to name is a warning sign.

2. Which awards and figures can you verify? Ask for the festival, the year, the client and the campaign behind each claim, since "15+ awards" and "500+ projects" are the agency's own words.

3. Which result will be measured, and from what starting point? Agree before the start on one or two indicators you already track, such as sales, leads or branded searches, and record their level on day one. Without a baseline, no report can show that the campaign worked.

Where does this ranking stop?

Three limits, stated clearly, because a ranking that claims to settle everything is not useful.

It is built only on public information. We read what each agency publishes on its homepage and checked that the sites were online in November 2026. We did not audit a single campaign, interview a client or verify an award. An agency that says little and works very well will be underrated here.

It cannot know your brief. An agency that suits a consumer brand with a large media budget is rarely the right partner for a local shop or a B2B company with a long sales cycle. The Best for lines matter more than the order.

It ages. Agencies open, change scope and close, and websites change. This page is reviewed every 90 days, and the reread date is stated in the method.

What can an agency do that software cannot?

This is the honest part, on a page that a software company publishes. An agency beats software on work that needs a local room: knowing how Sofia audiences react to a Bulgarian-language joke, choosing which outdoor site or event fits a brand, and writing a campaign that a client's management will defend. None of that is automated today, and anyone who promises otherwise should show proof.

Software does better on the repetitive, measurable part of the work around a campaign. Sorank is software, not an agency. It handles keyword research, article writing, internal linking, publishing to your site and tracking how often you appear in the answers AI assistants give. Pricing starts at 99€ per month, with 3 days offered and a card required at sign up. If you would rather talk it through first, book a demo.

Conclusion

If you want a single recommendation: GOBOX for a full-service creative brief in Sofia, AdwayCreative for performance advertising on Google and social platforms with video and outdoor, DNA for TV and campaign work, and The Locals for events and activations.

Before you choose, ask each agency for the names of its Sofia team and the proof behind its figures. The campaigns that last are built on a team you can meet and on results you agreed before the start. For the view from the agency side, read our SEO agency guide.

Honorable mentions: other advertising agencies in Sofia worth knowing

Two other agencies that state a Sofia address or office on their own sites are worth a call. Their focus is narrower than the ten above: one works on influencer marketing and the other on Google Ads.

Influentica	influentica.bg	Influencer marketing agency with an office at 13 Bryast street in Sofia, offering services for businesses and for influencers
