Fastest Growing UK Startups Offering Sponsorship That You Can Reach Out To Today
Now might be your best opportunity so far this year to secure a visa-sponsored role in the UK.
If you have been doom scrolling on LinkedIn over the past few days like me, you've probably seen that every other day there's another startup announcing an expansion into London.
Either opening brand new offices or shifting to London as their European HQ.
It's clear that these employers are doubling down on UK talent, and they're more open than ever to offering sponsorship in the UK.
Even though it has become more expensive over the last few years, UK sponsorship costs just a fraction of what they'd pay to hire US talent.
Whether you're a UK grad, an experienced hire, or even looking for relocation, sponsored opportunities are popping up left, right, and centre for the right candidates.
I'd forget about FAANG, investment banks, and Big 4 for a moment and fully take advantage of this moment.
