Organising a company anniversary celebration: how to make it truly meaningful for your employees

The company you work for has been around for X years, or there is something else special to celebrate: an acquisition, a milestone, a moment for the whole team to reflect on. And you get to organise this company anniversary celebration. On paper, it seems simple: drinks, a cake, a speech. But you don't want yet another gathering where everyone is checking the time after an hour. And certainly not an afternoon where everyone spends two hours staring at a PowerPoint about the company's history. You want people to say at the end of the day: ‘This felt like a real celebration, and I'm proud to be part of this company.’

I'm Suzanne, an event producer at InnStyle. I regularly help organise anniversary celebrations, for companies that have been around for just two years through to those with a history of sixty years or more. The best thing about these events? There is almost always emotion behind them: pride, gratitude, sometimes a touch of nostalgia, and that makes an anniversary celebration a little more personal than a regular business event.

In this article, I'll walk you through how to organise an anniversary celebration that people will remember: from budgets and tips to striking a balance between looking back and celebrating, and from energisers to the right spaces and a bad-weather plan.

Who organises a company anniversary celebration, and what exactly is being celebrated?

Enquiries about anniversary celebrations usually come to us directly from the management team, through an office manager or someone in HR, and sometimes through the director's assistant. The management team is often closely involved too. That makes sense: it is a special, and perhaps personal, moment to celebrate.

What is being celebrated varies widely. Sometimes it is a milestone anniversary of the company, sometimes a particular product or a long-standing employee's years of service. The scale varies just as much: one company has only been around for a few years but already wants to celebrate, while another is celebrating a hundred years of history. Organising an anniversary celebration is essentially organising a company party with an extra emotional layer: the guests are almost always the employees themselves, and sometimes partners join them too.

How do you make sure it doesn't become a boring history lesson?

An anniversary celebration starts with the same foundations as any other event: we explore the goals and ideas and ask questions to get to the heart of them. How big do you want to make it? Are you looking for décor, entertainment, or would you like to add something else yourself? If you don't have an immediate answer as an event manager, that's no problem: it gives us the chance to surprise you with our ideas, rather than leaving you to think of everything yourself.

What really matters at an anniversary celebration is the balance between looking back and celebrating. Many companies want to share their history, and that makes sense, because it is the reason for the celebration. But a lengthy two-hour plenary session on “how things used to be” is something best avoided.

''I would strongly advise against a two-hour plenary session on the history of the company. Fifteen minutes at most, taking guests through the story and rounding it off with a toast. That’s enough.''

In short: keep the look back brief and personal, and leave the rest of the evening for the celebrations: drinks, music and shared nostalgia.

Anniversary budgets are often higher: here’s how to use yours

Management often has a bigger budget for an anniversary, and there’s a clear reason for that. An anniversary taps into a sense of pride: you’re celebrating what the company has achieved, and the part employees have played in that success. That emotional value makes management more inclined to spend a little extra, even if it might not directly benefit marketing or sales, as a product launch would, for example.

I was recently in touch with an event manager who had initially been given a tight budget. When it later turned out that there was also something to celebrate, management made extra funds available after all. Some of that went towards a coloured carpet and extra decorations at the entrance.

Extra anniversary budget often goes towards:

• Décor, such as a coloured carpet, balloons with your logo or illuminated letters along the route from the car park
• Entertainment, upgrading from background music to a mobile DJ, for example, or even a fixed DJ booth
• Food and drink, such as a lovely glass of Cava (€8 per guest) for the toast, a standing dinner and food trucks instead of a standard buffet, or a logo on a cake or an ice cube in the cocktails (from 50 cents to €1 extra per item)

Working with a modest budget instead? Choose things that make a big first impression but have less impact on your overall budget. I would go for a coloured carpet (ranging from €140 to €275) and a photo booth (a lasting, personal memento from €430). Those two make the biggest impact for relatively little money.

5 InnStyle tips for an unforgettable company anniversary

• Tip 1: create a VIP entrance with a carpet - it’s something almost everyone overlooks when organising an event, yet it sets the tone straight away. Guests walk in and immediately think: this is our moment. In a bright, recognisable colour, it instantly creates a Hollywood feel, and it looks great in photos too. The more good photos you have, the more content your marketer can publish.
• Tip 2: set up a photo booth with a personalised photo strip - include the date, the anniversary year and the logo, and your team will have a tangible memento of the evening straight away.
• Tip 3: incorporate your logo into food and drink - even small touches can do the trick: a special logo on pastries on arrival or, if you really want to go all out, an ice cube with your logo in a cocktail. Or consider personalised cocktail sticks for the savoury snacks. At a celebration like this, ‘less is more’ does not apply – the more you go all out, the better.
• Tip 4: scale up the entertainment – on a modest budget, start with pleasant background music for drinks, then make it increasingly festive as the evening moves towards dancing. Or choose a Rolling DJ: an affordable way to create a party atmosphere straight away, without the equipment and space a live band needs.
• Tip 5: consider illuminated letters or themed lighting - celebrating sixty years? Put up a large illuminated “60”. Or even your company name. It is a simple visual statement that appears in every photo of the evening.

How do you bring in nostalgia without making it dull?

The company's history is part of an anniversary celebration, but it does not have to be told in a long speech. Instead, think of something guests can discover for themselves: a photo exhibition, or a timeline running through the foyer with stories from the past. Considering something like this? We would be happy to put you in touch with our partner who handles printing for events – giving you one less thing to think about.

A lovely moment for a toast often comes naturally during the speech: at a pre-agreed point in the speech, our staff circulate with trays to give everyone a glass of Cava for a toast. It is a brief moment, but one that stays with you (and a lovely opportunity for the photographer, if there is one).

Want something more interactive? A pub quiz with personal or company-related questions works well at an anniversary celebration. It brings the company's history into the occasion in a light-hearted way, and you can combine it with a moment on stage for the winner, complete with streamers and a light show.

What are plan A and plan B if the weather does not cooperate?

At InnStyle, a party never depends entirely on the weather: there is always a hospitality space (such as the Foyer in 2.0) as a permanent base, and if it is too small, we can put up marquees outside to extend the space.

Is the weather good? Then we also use the terrace and the covered outdoor area, adding atmospheric lighting, for example. Even in light rain, it is still lovely to sit outside under cover. Just do not assume you can move the entire bar outside: its usual location is indoors.

If the weather really does not cooperate, the party moves entirely indoors, with extra marquees if needed. Allow around €1.000 for one marquee, and about €2.000 for two marquees.

One thing to bear in mind: amplified sound is not always permitted outdoors. This means a rolling DJ is sometimes not an option outdoors, while live acoustic music is allowed. This creates an intimate, classic atmosphere. Want to really let loose? Then indoors is the best choice.

Which spaces are right for an anniversary celebration?

The most important rule of thumb: avoid a space that feels too large for the number of guests. That dampens the atmosphere faster than a cramped space.

Hospitality spaces, such as our Leisure Café, naturally offer a warm, homely atmosphere and work well with a separate entrance complete with a red carpet (or one in your own colour, of course). Plenary spaces such as Aarde and InnSpiratie also work well for an evening celebration thanks to the lighting equipment already in place. Aarde is a little darker, making it better suited if you want to focus on creating a party atmosphere, while Water in the same building is a brighter space.

InnSpiratie is a popular choice, but bear the number of guests in mind: with the dividing curtain closed, you will generally need 300 to 400 people to make the space feel comfortably full, and without the curtain, closer to 500 to 600.

Ready to organise your company anniversary celebration?

An anniversary celebration that truly resonates with employees takes more than drinks and a cake at the office. It is about balancing a brief, personal look back with a party that really comes to life afterwards, while keeping an eye on the budget, making the right use of styling and entertainment, choosing a suitable space and having a plan for the weather that does not feel like a fallback. That is the difference between an anniversary celebration that fades from memory within a few weeks and an evening that colleagues still talk about years later.

At InnStyle, I help you think all this through from our very first conversation. You do not need to have a concrete plan yet. As the organiser, focus on getting the content right and making sure your guests know they are welcome; you can confidently leave the set-up of the spaces to us.
