2026 marks Ten4’s 25th year in business. To celebrate, and to give thanks for our longevity, we thought it might be fun to share 25 things we’ve learned over our first quarter-century.
Hopefully some will be insightful, helpful and maybe even useful if you’re in the early years of running your own agency. Some might apply to any business … not just those of you who noodle about with code, content management systems, Figma and all the rest of it. Time will tell.
But brace yourself — #1 is a bit of a downer...
#1 Failure is inevitable
So why start on such a downer?
Because it’s true!
We all fail. Often. But if we’re not failing, we’re not striving.
The real lesson in failure is that it’s rarely the end of the world. Sure, every time we put in a lot of effort on a proposal that we don’t win, it hurts. It’s hard to reconcile the hours, days, weeks of effort our team pours into pitching our expertise, only to receive the knock-back. “Sorry — not right for us at this time”, “Sorry, the winning agency just seemed to get us”, or worse, the ghosting. No response at all after a few polite nudges for an update…
But here’s the thing we’ve learned, and relearned, over 25 years: failure is rarely final.
Five years ago, we poured our hearts into a pitch for Tower Bridge. We wanted it badly. We believed we could do something special. And then … we didn’t get it.
It stung.
We could have quietly filed it away as a near-miss. Instead, we talked about what we’d learned. What we could sharpen. Where we could be braver, clearer, better.
Fast-forward to when the tender came around again.
We pulled out the stops.
We brought everything we’d learned from the first time — and everything we’d learned in the years since. This time, we won. And we launched the Tower Bridge website in November last year.
Failure didn’t close the door. It showed us how to open it next time.
So yes, failure is inevitable. But so is growth, if you’re willing to sit with the discomfort, learn the lesson, and have another go.
#2 Long-term partnerships beat short-term wins
Don’t get us wrong — new work is exciting. Winning a pitch gives you a buzz. There’s energy in the unknown, in the fresh start, in the feeling that you’ve been chosen. But that feeling fades quickly if every relationship starts and ends the same way.
What really sustains an agency over time are the partnerships that last.
We’re incredibly lucky to have clients who’ve put their faith in us in the long term. We’ve worked with Derwent London for 13 years. We’ve run the website for the National Television Awards for nearly 15 years. Stiff + Trevillion have been at Ten4 client for 20 years this year! That still makes us pause when we say it out loud.
Because a relationship like that is a gift. There’s the obvious, practical benefit: long-term clients bring stability. Financially, yes, but also emotionally. There’s a deep sense of reassurance in knowing you have a bedrock of organisations who trust you, who understand how you work, and who don’t disappear at the first wobble.
Psychologically, that matters more than we probably realised in the early years.
When other clients come and go, as they inevitably do, those long-term partnerships give you confidence. They remind you that you’re doing something right. That your way of working has value. That you are relied on.
The best partnerships evolve beyond client and supplier. They’re built on mutual respect for each other’s expertise. On honest conversations. On a shared understanding that good work takes time, trust and a willingness to challenge each other when it counts.
Those relationships don’t just produce better work, they make the hard days easier. They give you the confidence to keep going when the industry feels noisy, uncertain or relentlessly short-term.
So yes, short-term wins feel good. But it’s the long-term partnerships that carry you through the years.
#3 Culture is at least as important as pay.
That statement isn’t always intuitive, especially in a world that often treats compensation as the ultimate signal of value. But over time, it’s the conclusion we keep coming to.
Pay is important, clearly. It’s often what attracts people. But culture decides whether you deserve to keep them.
Ten4’s culture has been shaped by a long series of practical decisions: where we worked, how we spent time together, the structure of our team, and what we chose to protect when circumstances changed.
At different points that meant sharing daily lunches around a table, continuing to prepare food even when it became inconvenient, and later accepting that remote work completely changed what “being together” looked like. What stayed consistent wasn’t the ritual itself (it was never really about the free sandwiches), but the belief that time, care, and shared moments matter. If you stop making space, culture erodes.
Culture also shows itself under strain. When people face illness, family changes or personal upheaval, culture stops being an abstract idea. It’s evidenced in flexibility, trust, and judgement on the fly, beyond what’s written in policy.
We haven’t always got this right. But one mistake we’ve managed to avoid is treating culture as a vibe: something that naturally emerges if the work is interesting and the pay is good.
Culture is a vibe, but it’s also an effort that good pay doesn’t absolve you of. Why? Because nothing can compensate for a lack of care, trust, listening, difficult trade‑offs and active decisions. These things, just as much as pay, show your team what you actually value.
That’s lesson #3.
More to follow.
