Web-based content editor Startups

Quiller, founded in 2014 by Dylan and Mark Tanner, helps sales and marketing teams create beautiful web-based proposals, quotes, and presentations as an alternative to PDFs and PowerPoints. Starting from Dylan's personal frustration with proposal creation at his micro agency, they grew to 3,000 customers and 45 employees through a freemium model, viral loops, and eventually moving upmarket to target larger sales and marketing teams. The company has raised $7.5 million and learned valuable lessons about freemium's tradeoffs and the importance of focusing on the right customer segment.
