After attending the company's annual customer conference, William Blair analyst Bhavan Suri says Alteryx's demand trends remain "very healthy" and that the company is seeing accelerating traction with professional data scientists. Further, Alteryx continues to witness limited competition, Suri tells investors in a research note. The analyst believes the event reinforced his thesis that the table has been set for Alteryx to "walk numbers up" throughout 2019 and sustain attractive growth rates for the next few years. He keeps an Outperform rating on the name.
