Investment Rationale:

645 got introduced to Thinknum co-founder Justin Zhen in 2014. We were quickly impressed and joined with Green Visor Capital to put together a seed investment round for the company, before the business went through 500 Startups Accelerator. At the time, 90% of the world’s data had been created in the previous two years. Thinknum's product filled a gap in the market by enabling financial institutions to perform advanced analytics on data that was previously not able to be analyzed. This, mixed with rapid revenue growth and strong early customers got 645 excited about the opportunity of partnering with this exceptional team.
