What I'm looking for #2: Off-shore site launch in Poland

I'd be happy to start and lead a development team/site in Poland for a expanding company (offshore/remote).
This may be excellent opportunity for cost-effective employment of highly skilled people - effective growth for you company.
I did that before with success - I was a part of initial startup team for medium-size Canadian company.
Also I worked for a number of companies as consultant in initial phase and during remote site launch. All of them succeeded! (can't display names here)

Your project may be initially started as onsite work with location based in any place on Earth for few months to train/launch/startup, then moved to Poland.
Project team may be started from scratch or based on existing Kemu Studio team.
  • Details - Location
    I propose a west of Poland, 150k+ city called Zielona Gora (translated to: Green Hill). Close to Berlin, Poznan and Wroclaw - 3 very good airports.
  • Benefit - People
    Local IT-job market in Zielona Gora has been taken over years ago by one quick-grown IT company (specialized in Digital TV), which employed and trained 1000+ people in peak time.
    Now the company is not that big anymore, slowly contracting from 2008 recession - which means, a lot of experienced IT-people live there - available for job market.
    There are only few local IT companies to employ those people, so this may be great opportunity to employ your experts on unbalanced IT job-market.
    There is also excellent IT University, producing trained graduates every year.
  • Details - Cost effective
    Simply, it's a cheap place in the middle of Europe !
    Consider living there as 5-10 times cheaper than London. This means cost-effective office space, salaries and maintenance costs.
    Yet, it's EU standard compliant civilized place.
  • Details - Final
    If you're still reading this, you should probably call me :)

Service legals

I provide services through one of my companies
  • Kemu Studio Limited in UK - EU-VAT registered
  • Kemu Studio in Poland - EU-VAT registered
