Bain & Company has been using generative AI to rapidly build working replicas of software products belonging to potential acquisition targets, fundamentally altering how private equity investors assess whether a deal is worth pursuing.

The consulting firm, which dominates private equity due diligence globally, has created hundreds of AI-generated prototypes as part of what it calls "outside-in" diligence — essentially rebuilding a target company's product from scratch to test how much of its value holds up under scrutiny, according to a report by the Financial Times.ft+1

How Vibe Coding Becomes a Deal Tool

Vibe coding — the practice of building software by describing desired features in plain English to an AI tool, which then writes the code — has moved from a consumer novelty to a professional evaluation instrument at Bain. Staff armed with tools like Anthropic's Claude Code can attempt to recreate the core functionality of a SaaS platform in days rather than months.Web Pulse+2

The logic is straightforward: if consultants with no engineering background can replicate a software company's key features quickly and cheaply, that company's competitive moat may be thinner than its valuation suggests. Conversely, features that resist replication represent genuine defensibility worth paying a premium for.Web Pulse

Bain documented a similar prototype-building exercise in an October 2025 report focused on an AI-native healthcare software company. The scale has since expanded dramatically, with hundreds of prototypes suggesting the approach has shifted from proof-of-concept to standard procedure.Web Pulse

A Growing Threat to Software Valuations

The technique gained broader visibility in February 2026 when CNBC reporters used Claude Code to vibe-code a working replica of Monday.com , the project management platform, in under an hour for roughly $5 to $15 in AI credits. Monday.com's stock fell sharply days later after the company issued weak guidance amid mounting AI disruption fears.cnbc+2

Bain's deeper partnership with OpenAI, announced in May 2026, extends this capability further. The firm invested in the OpenAI Deployment Company, a new venture focused on helping businesses deploy AI across critical operations, with private equity due diligence highlighted as a key area of collaboration.Cision PR Newswire

Implications for the Deal Market

Bain has not disclosed specific targets or financial details tied to its vibe-coding initiative. But the approach poses an existential question for software companies seeking buyouts: if your product can be replicated in days by non-engineers, what exactly is a buyer paying billions for?Web Pulse

The answer, according to industry observers, lies in what cannot be easily cloned — proprietary data, deep integrations, regulatory compliance, and customer trust. For private equity firms evaluating software deals, the era of taking a target's technical moat on faith appears to be ending.Linkedin+1
