‘Claude AI killed my startup’: Founder says Anthropic update wiped out her AI business overnight

Ira Bodnar, co-founder of ad automation startup Ryze, said an update to Anthropic’s AI assistant Claude severely impacted her company’s growth trajectory.

Posting on X, Bodnar wrote: “I woke up today and Claude killed my startup. We got several hundred paying clients in 2 months, was growing like crazy. One Claude/Manus feature and our close rate dropped from 70% to 20%. Claude just made our entire product category obsolete.”

What her startup built

Ryze had developed an AI agent designed to automate digital advertising management. According to Bodnar, users could grant the system access to Google and Meta ad accounts, allowing the AI to manage campaigns autonomously.

She said customers responded strongly to the product, helping the company secure hundreds of paying clients within two months and achieve a 70% sales close rate.

However, after Claude and Manus introduced connectors for Meta Ads, Bodnar said potential customers began reconsidering third-party tools. While she noted that Claude currently cannot directly modify ad accounts and lacks access to Google Ads, she added: “But give it a few months, and it will. So building here feels pointless.”

Pivot already underway

Despite the setback, Bodnar indicated the startup would survive. She said the team had anticipated rapid AI platform expansion and had begun pivoting weeks earlier.

“Our current business will be fine anyway. We knew what was coming and started actively pivoting a few weeks ago,” she wrote, adding that Ryze is now focusing on building complex workflows for large ad agencies managing hundreds of accounts.

She claimed some clients manage up to 600 accounts with six people, describing the scale as “insane”.

Wider AI disruption debate

The incident has reignited discussion around how rapidly advancing AI platforms can disrupt smaller startups built on top of them. As AI companies expand into vertical integrations such as advertising, coding, research and workflow automation, niche SaaS products may face sudden competitive pressure.

Claude has recently expanded beyond chat-based interactions into agentic tools such as Claude Code and Claude Cowork, enabling deeper workflow automation.

Social media reactions to Bodnar’s post were mixed. Some users described her pivot as strategic rather than a failure, while others discussed building differentiated tools that outperform general AI agents in specialised advertising tasks.

The episode highlights the volatility of building startups in the AI ecosystem, where platform-level updates from major AI firms can rapidly alter competitive landscapes.
