RenoFi is a U.S.-based FinTech that uses the after-renovation value instead of your home's current value, enabling you to borrow the most money at the lowest rates.

Doing more with less with a Modern Data Platform and ML at home renovation FinTech
During the discussion with Adam Kawa, Michał Wróbel said:
“It's fairly easy to have a batch ML prediction, compared to online predictions and we've been playing with that. And for batch ML on Google, you can use DBT with BigQuery ML. And that's what we've been trying to do. In BigQuery ML, obviously there's one pain point because usually data scientists are used to Python and all the transformations they do, they've been taught in Python and that's the main thing they're using. But because dbt these days is such a success and you can SQL is a lingua franca of data and everyone knows it.”

Volt is building the global infrastructure for real-time payments.

How we built a Modern Data Platform in 4 months for, a FinTech scaleup is building the world’s first global real-time payment network, powered by open banking. To build a payment platform that is fast and reliable, they need to use huge amounts of data from different sources such as: translation status, transaction quality, availability of banks, quality of internal processes and more. They decided to create a platform that processes and combines data from all sources. Together with GetInData, they designed and implemented a Modern Data Platform that was based upon Cloud components including data ingestion(Airbyte), data transformation (dbt), orchestration (Amazon Managed Workflows for Apache Airflow) and a data warehouse (Snowflake).

Amazon Web Services helped us a lot in providing the relevant data to the regulator so that they are satisfied with our compliance setup. Amazon Web Services data centers have a number of certifications and we were also to provide permissions and access control accordingly to the regulator. Moreover, there are other requirements like failover failsafe mechanisms, backup mechanisms and disaster recovery mechanisms all of which could be built on our own as well but would require much more effort. These things are covered by Amazon web services.” - dr. Andreas Schranzhofer, CTO

Willa is a payments and invoicing app for US-based freelancer

Learning From Experiments Without A/B Testing - Case Study
During the conference Arunabh Singh and  Qi An presented one of their product experiments from Willa around how to utilize econometrics for causal inference in the absence of A/B testing. They used an econometric technique called Difference-In-Differences (D-I-D) regression to tease out the causal impact of simplifying the invoicing process using their app, on the invoice creation rate per user. They took advantage of natural variation in product usage between different kinds of users, and were able to reach statistically significant results cheaper and faster than via A/B testing. 
During this, they used technologies such as BigQuery and Jupyter/Databricks, and GCP more broadly, although the approach is platform agnostic.
