Firmus Media is a social media agency in Athens for online stores and B2B brands across Greece. We plan, write, design and edit your posts, run the paid campaigns behind them on Meta, LinkedIn and TikTok, and report what all of it did for your orders and enquiries, because a follower count on its own has never paid an invoice.

We start with your buyers, your products or services and what your competitors are paying to promote, read from the official ad libraries. Then we pick the two or three platforms where your customers actually spend time, rather than being everywhere at half strength.
Graphics, carousels, short videos and captions written in your brand voice and produced from one shared brand kit, so your feed looks like one company even when twenty posts go out in a month.
Every month starts with a calendar: date, platform, topic, format and the goal of each post. You see every post before it goes live, and your comments go into the brand kit so they stay applied next month too.
Meta, LinkedIn and TikTok campaigns built on the posts that already work organically, with audiences, retargeting and a budget tied to what a sale or a lead costs you, run together with our performance marketing team.
For a store, orders, revenue and cost per purchase from social; for a B2B brand, enquiries and cost per lead. Then reach and engagement, the posts and ads that started it all, and next month’s plan changed by what the numbers said.
We use AI for research, first drafts and reporting, which leaves our people more time for the parts that need judgement: the idea, the edit and the final check. Nothing is published unreviewed, and the method is on our AI & Automation page.

Where most online stores, consumer brands and hotels sell. Reels, carousels and stories planned around what your customers buy and when they buy it, with Meta ads putting the strongest posts in front of people who have not met you yet.
For companies that sell to other companies, LinkedIn is where the buyer and the decision-maker both read. We write for your company page and for the people behind it, since posts from people usually travel further than posts from logos.
Vertical video that looks native to the platform, cut for TikTok, Instagram Reels and YouTube Shorts from the same footage, so one good idea works three times instead of once.
Your product catalogue connected to Meta and TikTok, so posts can be shopped and dynamic ads show each visitor the products they viewed or left in the basket. It works with Shopify, WooCommerce and any store that can export a product feed.
Meta Pixel and Conversions API with purchase and lead events, the LinkedIn Insight Tag, UTM links and GA4 set up properly, so a sale or an enquiry from a post or an ad is counted as one. Longer guides behind your posts come from our content marketing team.

The ones your buyers use, which is usually fewer than you think. For B2B that tends to mean LinkedIn first; for online stores and consumer brands, Instagram and Facebook, with TikTok if you can feed it video every week. Two platforms done well beat five done at half strength.
Yes, when it is run as a sales channel and not only as a brand channel: catalogue connected, purchases tracked, retargeting for people who viewed or abandoned a basket, and creative tested against cost per purchase. What we will not do is promise a return on ad spend before we have seen your margins and your data.
We write, design and edit it: graphics, carousels, captions and short video. For your own products, people and premises we work from the photos and footage you already have or that your photographer delivers, and you approve everything before it is published.
That is set in the monthly calendar, per platform, from what your audience responds to and what you can keep up with. A steady rhythm matters more than a high number, since a feed that goes quiet for a month looks worse than one that posts twice a week.
Yes, on Meta (Facebook and Instagram), LinkedIn and TikTok, including catalogue and shopping ads for online stores. Organic posts and ads are planned together, so the ads promote what is already working and the posts warm up the people the ads reach. Our performance marketing guide explains why who runs the ads matters.
With tracking set up before the first campaign, so orders, revenue and enquiries from social are counted where they happen. For a store the monthly report starts with sales and cost per purchase, for a B2B brand with leads and cost per lead, then reach and engagement, and it ends with what we will change next month.
It depends on how many platforms you need, how many posts a month, how much video, and whether we also run your ads. We start with a look at your current accounts and goals, and quote from that. Tell us about your brand and we will come back with a scope.
