Processes, native specialists, and AI you can actually trust
Turn translation bottlenecks into a localization growth engine
Undertow is the fractional localization partner for B2B tech. We bring the processes and the native specialists, and we make AI produce something you'd put your name on. We embed in your team and run localization day to day. So expanding gets easier every time.

Managing translations is not what you were hired for
You work in marketing, and localization landed on your plate on top of your actual job. Either it all runs through AI and you hope for the best, or it all moves by hand and it's painfully slow.
You basically run a one-person department
You know what good looks like. You're also the only person in the company who has done this before, but you can't do everything at once, especially not as fast as your leadership expects.
Leadership wants you to "use AI"
Volume keeps going up and leadership wants it done for less. Doing the rest by hand does not scale, and AI can do far more than translate, but not with the setup you have now.
Does any of this sound familiar?
Three different starting points. None of them has a system behind it.
We build the system. Then we stick around and run it.
You don't have a translation problem. AI already does most of the translating.
What you need is a system: one that connects every platform your content lives in, every person involved, and that doesn't make your brand sound like a robot.
That's what we do at Undertow. We build the right processes, wire up the right workflows, and bring the right native specialists in each market. Then we run the whole operation with you, month after month, so it keeps improving instead of drifting.

You know your product, your brand, and your stakeholders. We bring the method, the tooling, and the patterns we have seen work across dozens of tech companies. We don't replace whoever owns localization today. We make them look good to the people they answer to.
A team that feels in-house, without the hire.
Sooner or later this becomes a headcount conversation. Here's what a partner gives you that a hire can't.
Day one, not month six
A whole team, not one person
Nothing permanent to commit to
No job spec, no six-month search, no ramp-up. We arrive with the method and the tooling already built.
Strategy, tooling, project management, and native specialists in every market. No single hire covers all four, however good they are.
What you need next year is not what you need today. We change as the plan changes. A hire is a permanent answer to a question that keeps moving.
And if you do decide to hire, the system is already built for them to walk into.
What that looks like in practice

How it works
01
A conversation
Thirty minutes. You describe how localization works today. No deck, no quote, no obligation.
02
We map what you have
A short, fixed-price piece of work. We go through your content, tools, workflows and people, and hand you a roadmap. Yours to keep, whether you work with us or not.
03
We build a system that works
The platform, the workflows, the terminology, and native specialists in each market.
04
We stay and run it
Month after month, so it keeps improving instead of drifting.
If it doesn't surface at least three things you hadn't spotted, you don't pay.
Don't just take our word for it
When it comes to translation, SEO localization, and multilingual marketing, I know I can count on Undertow. They always offer actionable insights and deliver high-quality content. It feels like working with trusted in-house colleagues.

One method behind it all
Different starting points, same underlying method. Nicola Calabrese, who founded Undertow, wrote it down in Localization in the Age of AI. He works through it every week with localization leaders on The Multilingual Content Podcast, and the AI part of it is set out in Can't We Just Use AI?, free to read.
What we run for clients is what's in those pages. None of it is a black box.
