Just months after it announced a $33 million Series B, Chicago-based M1 Finance today disclosed a $45 Series C.

The new financing event was led by Left Lane Capital, the same investor that led M1’s Series B. Bear in mind that so-called inside rounds are now a bullish sign in 2020, as opposed to in prior VC eras when they were viewed more cooly. Other M1 investors include Jump Capital, Clocktower Technology Ventures and Chicago Ventures, though only the first two appear to have taken part in this round.

Per M1, the Series C comes just 120 days after it raised a Series B. A good question is why M1 has raised more capital, and why Left Lane Capital wanted to lead two rounds for the consumer-focused fintech provider. Going back to our prior coverage, we can figure it out.
