Short answer: For most mid-market companies, no. Not as a replacement for your system of record. People who tried it say the build takes a weekend. The trouble shows up a few weeks later, usually as broken routing, missing security, integrations nobody owns, or new hires who expected HubSpot or Salesforce. Vibe coding works for small teams with narrow needs and for custom tools built on top of a real CRM. If you’re weighing build versus buy because your current CRM doesn’t fit, I’d look hard at how you picked it first. That’s usually where the problem is.
Key takeaways
- Building a working CRM with AI now takes days. Almost everyone agrees, even the skeptics.
- In the success stories, people built the few workflows they used and stopped there. Nobody tried to clone Salesforce.
- The failure stories share another: nobody planned for maintenance, security, integrations, or hiring.
- The most common middle ground is to keep a commercial or open-source CRM as the system of record and vibe code around it.
- These are public anecdotes, not a study. Treat the dollar figures as self-reported.

Why people are asking this now
In July 2026, Curative CEO Fred Turner told the 20VC podcast, “We just recently canceled our Salesforce contract because we have an internal CRM that was vibecoded.” He put the contract at $600,000 a year and the build at two months. Business Insider reached out to Curative to confirm the cancellation. Turner provided the dollar figure and the timeline.
That clip went everywhere. Within days, founders on X and LinkedIn were posting their own builds and, a bit later, their regrets. I read through those threads to see what happened to the people who actually tried it.
One caveat. Social posts are anecdotes. People share wins more than quiet failures, and some posters sell CRM software or services. I’ve noted that where it applies.
The people who say it worked
They built only what they used
Darko Jovisic wrote on LinkedIn that his team dropped HubSpot for a CRM they built in two days. They were paying for hundreds of features they never touched. The two they needed, partner margin calculation and product management, required a workaround or a pricier plan.
He cared more about speed than savings. A new feature now takes an afternoon of prompts. Before, it meant waiting on someone else’s roadmap.
Sid Bharath, a startup founder, made the same argument on X. Most teams use fewer than half their CRM’s features, and some use only the pipeline. “What’s a deal pipeline? It’s a table,” he wrote.
They built something that isn’t really a CRM
My favorite example came from Zapier CEO Wade Foster, as Aakash Gupta described on X after interviewing him. Foster generally advises against vibe coding a CRM. He built one anyway, with no pipeline views, reports, or dashboard.
It runs on Saturday night and leaves him 10 to 20 drafted emails to key enterprise customers by Sunday morning, each with a reason attached. He approves them and barely opens the tool. It’s one narrow, personal workflow that sits next to a real system. Calling it a Salesforce replacement would be a stretch.
Small teams like the control
Todd Saunders, CEO of Dalton Mills, asked on X whether anyone was actually doing this. He then summarized 400+ replies. A vocal minority said it worked for them, usually on very small teams that valued control. Almost nobody claimed success beyond a handful of users.
The people who say it went wrong
Back to HubSpot in two weeks
Saharsh Agrawal, co-founder and CEO of Surface Labs, posted the clearest failure story on LinkedIn and repeated it on X. Claude built his two-rep team a CRM in a weekend. It worked. Then it started breaking:
- A routing rule failed; only the busy engineer who built it could fix it, and a lead sat unassigned for three days.
- Sales candidates asked which CRM the team used and lost interest when they heard “we built our own.”
- Apollo, Clay, and their email tools connect natively to HubSpot and Salesforce. Their homegrown CRM needed custom API work for each one.
Building version one was the easy part, he wrote. “The hard part is everything after that.” They went back to HubSpot.
It looked finished. It wasn’t secure.
Wes Snow, CEO of Ascendix Technologies, vibe-coded a CRM in an afternoon and then had his tech team review it. Per his LinkedIn post, they found weak login protection, unencrypted client data, and no record of who had accessed or changed anything.
For a mid-market company with customer contracts, pricing, and possibly regulated data, that last gap matters. Owen Cole, who builds backend business systems, made the same point on X: “the app is the easy part.” He argued that what kept companies on Salesforce was the audit log, the permission matrix, and years of edge cases.
The hard part starts on Monday
“When someone says they vibe coded their own CRM over a weekend, I believe the part about the weekend.”
Larry Augustin, former CEO of SugarCRM, in a LinkedIn post
Augustin’s worry is ownership. A vibe-coded CRM depends on whoever wrote the prompts. When that person leaves, the customer records have no owner. He added that one of his own AI agent connections failed quietly for over a month before anything caught it.
Rachel Squire, a HubSpot consultant, has seen the longer version of this story. In a March 2026 LinkedIn post, she described homegrown CRMs that, five years in, need full-time developers, custom integrations that take months, and reports routed through a dev queue. She has helped many companies migrate off them. (She also notes she does that work, so weigh it accordingly.)
The savings math gets questioned
Pablo Martell, a CPA and startup CEO, replied to the Curative story on X. Requirements grow and someone has to maintain the system, so he called the $600K savings claim inaccurate. His verdict: “Buy > build in most cases.”
Moving people over is work too. One X user who replaced Monday.com with a custom build said the coding took about two days, but getting the team onto it took three weeks.
Thinking about building because your CRM doesn’t fit? That’s usually a selection problem. Our 12 CRM selection criteria show what to test before you build or buy, and our selection process walks you through it.
The middle ground most people land on
Oddly, people on opposite sides end up in about the same place. Keep a real CRM as the system of record. Use AI to build what sits around it.
Colby Ricker put it bluntly on X. A business analyst may soon be able to vibe code a better CRM than Salesforce. They won’t be able to secure and integrate it faster than if they had built it on top of Salesforce.
Matt Silver, building the freight company Cargado, took a similar line on X. He wasn’t going to vibe code a CRM, but he wanted off HubSpot for something flexible enough to manage through Claude Code. Many of the replies Saunders summarized pointed to open-source or flexible platforms such as Twenty and Attio as smarter starting points.
Salesforce, unsurprisingly, agrees that infrastructure is the hard part. Its spokesperson told Business Insider that running secure, compliant software at scale is the real challenge.

Pro vs. con experiences side by side
| Issue | What the “it worked” camp reported | What the “it went wrong” camp reported |
|---|---|---|
| Build time | Two days (Jovisic); two months at Curative (Turner) | A weekend or an afternoon, which nobody disputes (Agrawal, Snow) |
| Scope | Only the few workflows actually used (Jovisic, Bharath, Foster) | Requirements keep growing over time (Martell) |
| Cost | Subscription fees cut, with Curative citing $600K a year | Savings offset by maintenance and engineer time (Martell, Squire) |
| Security | Rarely discussed | Weak logins, no encryption, no audit trail (Snow, Cole) |
| Integrations | Rarely discussed | Custom API work for every tool (Agrawal) |
| People | Control and fast changes for tiny teams (Saunders’ summary) | Hiring friction and slow adoption (Agrawal, Monday.com switcher) |
| Ownership | The builder owns it, which is fine at small scale | No owner when the builder leaves (Augustin) |
What five AI assistants said
Before reading these threads, I asked ChatGPT, Perplexity, Claude, Google AI Mode, and Grok the same question from our CRM AI FAQ page. Four of the five come from companies that sell AI coding tools, so I expected some cheerleading. I didn’t get any.
All five said no for most businesses. All five said the subscription pays for the hard parts: security, compliance, integrations, and someone else fixing failures at 2 a.m. They also recommended the same hybrid the people above landed on. The humans just had the scars.
What this means for mid-market companies
Nearly every success story above comes from a startup or a tiny team. I don’t think that’s a coincidence. Our clients are mid-market manufacturers, distributors, professional services firms, and tech companies. They have ERP integrations, quoting, territories, channel partners, and dozens of users. That’s the profile where the failure stories bite hardest.
Building may still make sense if:
- The tool covers a narrow workflow your CRM handles badly, like Foster’s email agent.
- It reads from and writes back to your CRM rather than replacing it.
- Someone with engineering skills owns it, with a named backup.
- It gets a security review before it touches customer data.
If your real complaint is that your current CRM doesn’t fit how you sell, look at why companies switch CRMs and how to build your CRM requirements. We also compare the options in Traditional, AI-Native, or Build Your Own.
Frequently asked questions
Yes. Several founders report building a working CRM in a weekend or less with tools like Claude Code. Keeping it running, secure, and connected to your other tools is the hard part.
Curative told Business Insider it canceled its Salesforce CRM contract. CEO Fred Turner cited the $600,000 annual cost and two-month build time, but they were not independently verified.
People who tried it most often cite unowned maintenance, weak security and missing audit trails, custom work for every integration, and hiring friction because candidates expect HubSpot or Salesforce.
Yes. Keep a commercial or open-source CRM as the system of record and use AI coding tools to build the extra tools you need on top of it through its API.
