The Big Take: How an ‘Entrepreneur of the Year’ Brought the First Big Bust to the AI Boom
Sachin Dev Duggal, once celebrated as the founder of a leading AI startup, Builder.ai, saw his company soar to a $1.5 billion valuation before it collapsed under allegations of inflated revenue and financial mismanagement. Builder.ai, based in London, aimed to simplify app development using AI, promising to make building software as easy as ordering pizza.
At its peak, Builder.ai attracted major investors including Microsoft and the Qatar Investment Authority, and Duggal was named Entrepreneur of the Year in the UK. The company rode the wave of excitement around generative AI, positioning itself within the emerging low-code/no-code movement that enables users to create software without extensive programming skills.
From Glitz to Bankruptcy
Despite the buzz, a deeper look revealed troubling financial practices. Builder.ai reportedly booked $142 million in sales from resellers who never paid and claimed $107 million from customers with minimal deposits. These tactics inflated revenue by approximately 300%, helping Duggal secure emergency loans.
Further investigations uncovered a scheme called “round-tripping,” in which Builder.ai, in collaboration with an Indian startup, fabricated sales to exaggerate revenue. The audit committee’s findings led to drastic consequences: a major lender seized nearly all of Builder.ai’s cash, pushing the company into bankruptcy by June 2025.
The Rise and Fall of Builder.ai
Duggal’s vision was clear—to democratize software development with AI assistance. He branded himself as Builder.ai’s “Chief Wizard” and appeared at high-profile tech events, even receiving media attention as an AI expert. However, the company’s early claims about its AI capabilities were questioned. Much of the software development was reportedly done by programmers in India, not AI systems, contradicting the startup’s public narrative.
Builder.ai’s aggressive fundraising benefited from the generative AI boom, with global venture capital flowing heavily into AI and machine learning startups. But as investors pushed for quick growth, due diligence reportedly took a backseat, allowing inflated claims to go unchecked.
Controversies and Legal Challenges
Duggal’s career has been marked by legal disputes and allegations stretching back over a decade. Earlier ventures faced accusations of embezzlement and financial irregularities, though no judgments were made against him. His leadership style was described by some former colleagues as charismatic but unfocused, with a tendency to prioritize salesmanship over technical execution.
Even as Builder.ai’s financial situation deteriorated, Duggal continued to assure investors of imminent funding rounds valuing the company at $2.3 billion. These promises never materialized. The startup accumulated debts owed to over 200 creditors, including major corporations and service providers.
Investor Reactions and Industry Implications
Industry insiders highlight Builder.ai’s collapse as a cautionary tale about the risks of hype-driven investment, especially in hot sectors like AI. When competition to back startups intensifies, thorough vetting can suffer, increasing the chance of overlooking warning signs.
Despite Builder.ai’s failure, some investors were slow to recognize the full extent of financial misstatements. A detailed audit revealed that actual revenues were far lower than reported, leading to swift actions like cash seizures by creditors.
Microsoft, holding a 2.7% stake, reportedly had little indication of the startup’s cash flow issues, as Builder.ai continued to pay for cloud services. Other major investors included Insight Partners, Lakestar, and Iconiq Capital, some of whom have distanced themselves since the bankruptcy.
Looking Forward
The Builder.ai story underscores the importance of transparent financial reporting and rigorous due diligence, especially as AI startups proliferate. For professionals in IT and development, it serves as a reminder to critically evaluate the claims and business models behind AI ventures.
As the AI landscape evolves, learning about the practical applications and realistic capabilities of AI tools remains essential. For those interested in expanding their AI knowledge and skills, exploring comprehensive training resources can provide valuable insights.
