What you need to know in advertising today

Ad tech veteran Michael Cassidy is embarking on his second act - and his first big bet is on the future of e-commerce.

The former CEO and chairman of ad tech company Undertone is trying to build a portfolio of profitable companies centered around technology and marketing services through August Spark, a family office fund he launched 18 months ago and runs with cofounder Stephen Wall.

His first big investment is in San Diego-based e-commerce agency BVAccel, which helps design, build, and optimize digital storefronts for several hot and up-and-coming direct-to-consumer brands. It also provides marketing services to clients, using data to map out the customer journey and optimize their e-commerce websites for conversion.
