Alex Lewalle

Who is Alex Lewalle?

Alex Lewalle is the CEO and co-founder of Slaask, a customer-communication software company that he brought to the SaaStock Europe stage in 2017. As a founder building in the crowded B2B SaaS space, Lewalle has spent his career wrestling with one of the questions that defines whether an early-stage software company lives or dies: have we actually found product-market fit, and how do we know? His SaaStock talk, "PMF in SaaS: True Disruption Or Illusion?", takes that question head-on and challenges one of the most comforting myths founders tell themselves.

What sets Lewalle's perspective apart is his refusal to treat product-market fit as a finish line. In his SaaStock Europe 2017 session he pushes back on the popular narrative that fit is a single "Big Bang" moment you discover once and then ride to fifty or a hundred percent growth. Instead he frames it as something more holistic and harder-won, a state that has to be continually re-found as a product, its market, and its customers all shift underneath the company. That clear-eyed, almost skeptical view of startup orthodoxy makes his talk a useful counterweight for founders who assume that early traction means the hardest work is behind them.

This page collects Alex Lewalle's recorded SaaStock appearances along with their transcripts, so founders and operators can revisit his thinking on product-market fit, disruption, and the discipline of building SaaS that keeps growing rather than coasting on a single early win.

About Slaask

Slaask is the company Alex Lewalle co-founded and leads as CEO, and it sits squarely in the customer-communication and messaging software category that exploded across B2B SaaS in the mid-2010s. Lewalle represented Slaask at SaaStock Europe 2017, joining a wave of founders building tools to help software companies talk to and support their users more effectively.

Slaask is the lens through which Lewalle examines the broader SaaS questions in his talk. Rather than pitching the product, his SaaStock session uses his vantage point as an operating founder to interrogate how a company in a competitive software market establishes genuine fit with its customers. The recurring theme is that disruption and product-market fit are easy to claim and far harder to sustain, and that the companies which endure are the ones willing to keep changing their product as they learn.

Because Slaask's specifics were not detailed on stage, this page focuses on the ideas Lewalle shared rather than company metrics. His talk positions the business as a working example of the central argument: that fit is not a trophy you win once but a relationship with the market you have to keep earning, especially as customer needs and the competitive landscape evolve.

Key lessons from Alex Lewalle's talks

Product-market fit is not a one-time Big Bang. Lewalle's central message at SaaStock is that founders dangerously misunderstand PMF when they treat it as a single discovery moment after which the company is simply "off to the races." He argues that this myth sets teams up for complacency, because real fit has to be re-established over and over as the market moves.

Take a holistic view of fit, not a single metric. Rather than reading fit off one growth curve, Lewalle favors a more holistic approach that accounts for how customers, product, and market interact. A spike in revenue or growth is not proof that the work is done; it is one signal among many that needs continual interpretation.

Be willing to change the product. A recurring point in his talk is the necessity of changing course, including the product itself, in order to keep fit alive. Founders who treat their early product as fixed risk watching their hard-won traction erode as conditions shift.

Question the disruption narrative. By titling his talk "True Disruption Or Illusion?", Lewalle invites founders to be honest about whether they are genuinely disrupting a market or simply enjoying a temporary tailwind, a distinction that determines whether early growth is durable or fleeting.
