Welcome to the Tearsheet Podcast. I'm Zack Miller.

We're experimenting with an interesting new series on the podcast called Marketing Talk. We're talking to top finance and fintech marketers sitting on the front lines of their business, hustling to bring in the next cohort of customers. As much as TechCrunch makes this stuff look easy, it isn't and we want to hear from marketers — in their own words — what's working for them, how they're structuring their teams, and what channels are delivering.

Today's marketer on the hot seat is Bill Walsh, Lending Club's general manager and head of marketing for personal loans. Bill brings an engineer's approach to marketing. The MIT grad began his tenure at Lending Club in an operations role, where rigorous problem solving was used to solve some of the biggest problems in the business. Now that he's leading marketing on the consumer side, he brings a similar approach.

We talk about how Lending Club defines marketing and approaches channels. We pay particular attention to a recent TV campaign you might have seen over the summer of 2018. Measuring and responding to the signal is core to Lending Club's approach and in the course of this 4 week broadcast campaign, Bill's team iterated twice. This puts ad agencies on notice  -- this is the new data driven fintech marketing world.

If you like this Marketing Talk series, let us know. You can hit me up on twitter at @newrulesinvest or via email at zack at tearsheet.co. Let me know what you think and if you'd like to nominate a marketer or growth guy or gal for the show.

Without further ado, here's Bill Walsh.
