Upvest - CTO & Co-founder Link to this heading

2020/06 - Current, Berlin, Germany Link to this heading

I joined Upvest to build next generation investment infrastructure and to enable all the innovation happening in Financial Services and especially investment landscape. It used to be slow, expensive, and cumbersome to do that in this space with incumbent players, but we wanted to change that and allow companies to move fast and focus on their core products instead of worrying about infrastructure. I also wanted to work on something that matters. With our product we can help the next one hundred million people to get on the investment ladder and start preparing better for their future. After my time at Wise owning the Wise API as part of the overall business offering, I also wanted to build a pure API-only business. To me infrastructure and APIs are the foundational piece for any innovation nowadays.

When I joined Upvest we were still building our earlier product for blockchain asset custody. We provided a regulated (we were one of the earliest companies in Germany to get the Crypto Custody bank license needed for that) custody services for other companies that needed infrastructure for managing that, be it from cryptocurrencies to other tokenized assets like real-estate. But in the first months, we ended up realizing we want to go bigger and decided to pivot to provide a fully-fledged B2B investment infrastructure API for investing into any kind of asset legally investable, starting from ETFs, mutual funds to stocks and cryptocurrencies. I am a big believer in platforms and APIs are the building blocks of great products. I can power hundreds of investing products with my API.

Due to my integral involvement in this pivot to what the company is right now, I was made a co-founder. But to be honest that did not change anything, I had come in with a co-founder mentality already as this was my chance to build something great from scratch. Initially I was the CTPO looking after both product and engineering which would have been fine if we had stayed in blockchain but after the pivot I wanted to have dedicated domain expertise in this industry and a dedicated product function separate from engineering. So I split out and ramped up the Product function by seeding it with a Product Manager and helped hire our CPO to take it over. We work in cross functional teams though with a Tech Lead leading the engineers and working closely with their Product Manager.

I helped us set a framework of using Objectives and Key Results (OKRs) to drive focus in all departments. I have set up most of the initial people processes in the company due to the fact of having to deal with those first in Engineering as the biggest department (half of the company, 75 of 155 people, are in Engineering).

I created the engineering strategy to support our business objectives and designed the initial cloud native architecture and tech stack of the new platform. I set up the organizational structures, ways of working as well as the culture of autonomous teams needed in delivering software products effectively at scale. I ramped up the engineering team hiring processes and the team from 5 to 75 engineers distributed in Europe in a hybrid model.

I delivered the product to launch with our launch partner Ginmon in August 2022. I delivered product functionality for us to win customers like Vivid, Shares and some of the biggest neobanks in the world, Revolut and N26. And more to come…

I set up the API as a Product mindset and external facing Developer Experience capabilities around that to make sure our clients come first in everything we do. This is usually an overlooked area in companies.

I helped us raise a total of ~$80M of funding in our A and B-series fundraising. I have helped us hire and fill the rest of the management team. I helped us get all the needed bank licenses from the German regulator as well get thru all required audits.
