Q: How long did UK challenger banks bootstrap for? i.e., from initial incorporation to first institutional VC funding (Series A)
A: Here’s an interesting comparison list:

- Monzo Bank Incorporated on February 18, 2015, and received its first institutional VC funding in March 2016, approximately 13 months later.

- Revolut Incorporated on December 6, 2013, and secured its first VC funding in July 2016, around 31 months later.

- Starling Bank: Incorporated on June 18, 2014, and received its first VC investment in January 2016, about 19 months later.

- Atom bank: Incorporated on July 31, 2013, and received its first institutional VC funding in November 2014, approximately 16 months later.

- Tandem Bank: Tandem Money Limited was incorporated on August 1, 2013, and received VC funding in December 2015, approximately 28 months later.

These timelines reflect the periods between incorporation and the receipt of initial institutional VC funding for each bank. There were prior seed rounds but these were the Series A events.
