At Line 21, we work across live events, streaming broadcasts, and real-time communications. These are high stakes and trust-or-bust environments. And yet, for all the critical work we do, you'll rarely hear us say: “Here's who we work with.”

Valid Questions

“Can you show us examples of clients like us?”

“Can we speak to someone you've captioned for?”

“Do you have a case study for that kind of event?”

And the honest answer is… often, no. Because in this industry, NDAs are everywhere. They are the norm, and our silence echoes with intent.

Confidentiality is the rule, not the exception

When we're captioning live content, it's often not meant for public consumption. That could mean:

• Internal communications with sensitive information
• High-profile events still under wraps
• Live support for participants who require discretion or anonymity
• Partnerships where we serve AV teams or umbrella agencies, not the end client directly

In many of these cases, we're not discreet by choice, but by contractual obligation. We sign NDAs, respect confidentiality clauses, and build our entire workflow around the assumption that we won't be able to show or tell the outside world what we've done.

While it's not a marketing team's dream, it is part of the service.

The paradox of trust

Trust is everything in live captioning. Our clients choose us because they know we'll handle their content sensitively. With no leaks, no over-sharing, and by allowing the spotlight to dim on collaborative celebration.

But here's the paradox: the more trust we earn, the less we can say. Our best work is often invisible. Our proudest moments happen behind digital doors. The more high profile the client, the more likely we'll never be able to say, mime or ‘rhymes with' their name.

So what do you share publicly? We - and many others in the industry - focus on platforms and ecosystems. “We captioned a session using Zoom,” or “We provided captions for an event on Teams.” These are valid references, but they don't reflect the specificity of the clients or the trust those relationships are built on.

Our reality is different. We're often brought in by AV teams, or by communications providers operating under another brand. We're the silent partner under the umbrella. And often, the end client doesn't even want to know our name. Our success means everything just works.

Why we honour this silence

We could try to find clever ways to showcase the work anyway. We can weave whim-wrapped emails enquiring if the latest session could be considered newsworthy. But we embrace our roles:

Steady Support

Our team is made of real people who care about making your event accessible. Whether we're listening to the stream or tracking updates in the green room chat, we're present, responsive, and quietly keeping pace with you. We even include offsetting sanity loss when we share in the troubleshooting of a project - whilst not being the source of its hiccups.

Flexible Formats

Zoom, Teams, Vimeo, a platform you've never heard of and hope never to see again - we are fluent in all of them. And if we're not, we will be. Human or automated, remote or hybrid, our captions join the workflow and adapt as the event shifts shape.

Affordable Accessibility

Until you've seen someone's eyebrows raise in delight at not needing to lock into a hardware ecosystem for months on end, and enjoy the lowest rates in the industry, have you really enjoyed talking about being their captioning provider? We have.

We're proud to be part of teams that value integrity over credit. Our clients trust us with their content because they know we won't misuse that trust for visibility. Even when they send our support team videos causing them to exclaim ‘look at the captions' in tones reserved for sunset clouds shaped like a giraffe.

We'd love to tell you the stories. The global organisations we've supported. The last-minute save on a mission-critical livestream. The captioning team who made a difference in someone's ability to follow an event live. The Zoom seances we've been in. But we won't. Because the confidentiality we offer is beyond legal requirements, and our core values.

This is the use case

So, if you're wondering why our name doesn't appear more often in case studies or testimonial pages it's because the nature of our work is private. But that's exactly what makes us the right choice for clients who need assurance, not attention.

When we say we've worked with teams like yours, we mean it. Even if we can't say more.

And if you're the kind of client who needs captioning handled quietly, securely, and professionally then you know we already speak your language.
