Dave Clark, founder and CEO of an enterprise AI startup, shared on LinkedIn how he built a customer relationship management (CRM) tool in just one day using vibe coding tools.
Clark stated this was built to accommodate their specific sales needs. “We tried configuring an off-the-shelf tool for our cycle. Too many fields we don't need, missing the ones we do, forces a pipeline flow that doesn't match reality. Spent more time fighting the tool than using it,” he said.
“So I just built what we needed. Took a night and a morning.”
Besides the CRM tool, Clark also revealed how he built an end-to-end customer prototype tool and reworked the company’s deck into a web view in just a weekend.
“Three things that used to take months happened in 72 hours,” he said.
Clark was also the CEO of Amazon's Worldwide Consumer division, where he spent over 23 years, spanning multiple senior roles.
While this isn’t a surprising development, as users have long demonstrated the capabilities of vibe coding tools, it reflects the broader trend of enterprise leaders building custom solutions rather than purchasing SaaS products.
While not all of them can be verified, reports of such scenarios have been flooding social media for the last few days.
Maor Shlomo, founder of Base44, a vibe coding startup that got acquired by Wix.com last year, said on X, “Just heard of a customer that terminated a $350k contract with Salesforce for the custom solution they built on top of Base44.”
“I’ve been getting those stories on a ~weekly basis now,” he added.
just met a guy who canceled a $8.4M/year Zendesk contract because someone from HR vibecoded an app in @Replit that basically replaced it overnight

SaaS stocks on public markets have seen significant recent declines, with poor performance observed over the past few weeks and the last month.

Having said that, many experts also suggest that vibe coding and no-code/low-code tools are valuable for prototyping, experimentation, and internal automation.
They’re not currently reliable as a long-term foundation for SaaS or CRM products that will have paying users, sensitive data, or complex workflows that must also account for various compliance mechanisms and regulations.
