While at Index Ventures, Christian Lubasch helped two FinTech portfolio companies—auxmoney and Raisin— take their Data & Technology stacks to the next level. His work was instrumental in getting better data insight and supported the companies’ fast growth and expansion, thus being a key value driver over time. Given my personal experiences working with Christian, both as an investor and operator, I’m sure others will benefit from their exceptional work in the same way I did.
