Sometimes yes. Here is what an agency actually does for the money, when it is worth it, and when a platform gets you the same result without a retainer.
Let us be straight about who is writing this. get tagged is not an agency. We are a platform: you publish a campaign, verified Athens influencers apply, you approve the ones that fit. So read this knowing we have a horse in the race, and judge the argument on whether it holds.
The useful question is not which is better. It is which problem you have. An agency sells you judgement and labour. A platform sells you access and speed. Those are different purchases, and plenty of brands genuinely need the first one.
What follows is what sits inside a retainer, the five situations where paying it is clearly right, and the five where it is not.

Retainers sound expensive until you list what sits inside them. A good Greek agency is doing most of this every month.

If you need four of those five, you need an agency. If you mainly need the second one, casting, you are paying a retainer for a directory.

Neither column is a criticism of the other. They answer different problems, and the wrong pick churns within a month.

Choose an agency if
You are running a national campaign, not a neighbourhood one.
You need scripted, art-directed content rather than an authentic story.
You are working with large influencers whose fees need real negotiation.
Your category is regulated and every word has to be controlled.
You have nobody internally with time to approve applications each week.
Typical Greek market range: €800-3,000 per month plus 15-30% commission.
Choose a platform if
You have one venue, or a few, and your customers live nearby.
You want content that looks like a recommendation, not an advert.
You would rather pay with what you sell than with a cash fee.
You want to launch this month, not after a briefing cycle.
You can spend ten minutes a week approving the right applications.

Agency figures are the typical Greek market range and vary with scope and category.

| get tagged | Influencer agency | Global platform | Instagram DMs | |
|---|---|---|---|---|
| Cost per collaboration | A voucher, typically €20-50 | Cash fee + 15-30% commission | Cash fee, you negotiate | Cash or free product |
| Ongoing cost | Monthly subscription per location, no commission | ~€800-3,000 / month retainer | Subscription priced for global teams | None, but it costs your hours |
| Athens influencers | 450+ verified, real local audience | That agency's roster | Large database, few Greek influencers | Whoever replies to your DM |
| Who vets them | We do, every profile, manually | The agency | You | You |
| Time to first campaign | About 3 minutes, then our team reviews it | A few weeks | Days, once you know the tool | Weeks of outreach |
| Rights to reuse content | Yours to repost | Often charged separately | Varies by influencer | Negotiated case by case |

Ask us the same five. The answers for get tagged are in the cost breakdown.

No. get tagged is a platform. You create the campaign, verified Athens influencers apply, and you approve the ones that fit your brand. There is no account manager running the campaign for you, and no commission on each collaboration.
When you need someone to own the whole thing: strategy, negotiation with larger influencers, scripted content, paid amplification and reporting to a marketing director. Agencies are also the right answer for national campaigns and for regulated categories where the brief has to be tightly controlled.
The typical Greek market range is roughly €800-3,000 per month on retainer, plus 15-30% commission on each collaboration, with content usage rights often billed separately.
Yes, and many local venues do once the campaign shape is repeatable. The work an agency does at the start, defining the offer and the brief, is the hard part. Once that is settled, running the same campaign monthly does not need a retainer.
Tell us what you are trying to do. If an agency is the better fit for your campaign we will say so, because a brand that signs up for the wrong thing churns in a month.
