May 2023Series DQatar Investment Authority (lead); Epiq Capital; Blue Lion; ICONIQ Capital; Insight Partners; Jungle Ventures; Tapestry VC; Revo Capital; KSV Global$250M$1.6BBuilder.ai, founded in 2016 by Sachin Dev Duggal, is a London-based AI-powered composable software platform that enables non-technical users to build web or mobile apps through modular components and human-assisted AI, positioning itself against traditional no-code/low-code tools by emphasizing conversational interfaces. The company offers products like Builder Studio, Builder Cloud, Builder Now, Studio Store, and Studio Rapid, with offices in the UK, US, UAE, Singapore, France, and India. It has partnerships with Microsoft (including integration into Teams and Azure), JP Morgan & Chase, Etisalat UAE, and others, and was named in Fast Company's 2023 Most Innovative Companies list and 2022 Europas Scale Up of the Year. In May 2023, Builder.ai raised over $250 million in a Series D round led by Qatar Investment Authority (QIA), with participation from Iconiq Capital, Jungle Ventures, Insight Partners, and others including Blue Lion, Employee Stock Option Fund, Epiq Capital, KSV Global, Revo Capital, and Tapestry VC, bringing total funding to over $450 million. Funds were allocated to innovation, talent acquisition, technology development, and partnerships to solidify its leadership in AI-driven software development. The company highlighted strong momentum with 2.3x revenue growth and over 40,000 features deployed to customers in the prior year, amid a strategic pivot to human conversation-based app building. Investors like QIA viewed it as supporting innovative global economy shapers, while existing backers such as Jungle Ventures praised its resilience in tough markets. Post-round developments included a Microsoft strategic investment and reseller program inclusion just prior. However, later reports noted challenges with optimistic revenue forecasts and rising costs, contributing to eventual financial difficulties and insolvency filing, though these post-date the 2023 round.
May 2023Undisclosed stageMicrosoft--Microsoft took an undisclosed equity stake in Builder.ai, the London-headquartered app-building platform, in a strategic investment reported on 11 May 2023, two weeks before the company's USD 250 million Series D. Neither the amount nor the size of the stake was disclosed. The investment came with a deeper commercial collaboration: Builder.ai's Natasha AI assistant was to be added to the Microsoft Teams store and the platform would integrate Microsoft's cloud and Azure AI services. Microsoft's corporate vice president of business development said Builder.ai was creating a new category that lets everyone become a developer. Builder.ai founder Sachin Dev Duggal said the collaboration showed how customers adopting the platform also consume more cloud marketplace solutions. Builder.ai was founded in 2016 and later entered insolvency in 2025.
Mar 2022Series CInsight Partners (lead); Blue Lion; WndrCo; Nikesh Arora; International Finance Corporation; Jungle Ventures; Tapestry VC; Revo Capital$100M-Builder.ai, an AI-powered composable software platform (formerly Engineer.ai), enables non-technical users to build apps via low-code/no-code tools, emphasizing automation features like the 'Natasha' conversational AI bot. The March 2022 Series C round raised $100 million led by Insight Partners, with participation from IFC, WndrCo (Jeffrey Katzenberg), Nikesh Arora, and existing investors including Jungle Ventures, bringing total funding to $195 million. Funds were allocated to scale AI and automation capabilities, international expansion, and platform enhancements. The company reported strong growth traction, including a 230% monthly revenue increase from pandemic start to early 2021 and over 300% revenue growth in the prior year, aligning with no-code/low-code market trends. Builder.ai positioned itself as a disruptor by democratizing software development, assembling tools to automate app building, and targeting businesses shifting online. Investors highlighted its innovative model and vision, with Insight Partners' Jeff Horing noting its potential to transform application development. Post-Series C, Builder.ai continued momentum, securing a $250 million Series D in May 2023 led by Qatar Investment Authority (valuing it at up to 1.8x prior, reaching $1.3-1.5 billion), with 2.3x revenue growth and partnerships like Microsoft, JP Morgan, and Etisalat. However, later challenges emerged, including October 2024 debt financing amid overstated $220M revenue projections, leading to insolvency filing in May 2025 with cash reserves near $7M.
May 2021Series BRevo Capital$66M-Builder.ai is a London-based company founded in 2012 that provides an AI-powered no-code platform for building custom apps and in-app ecommerce experiences across industries like financial services, retail, education, and automotive. The platform, including Builder Studio, enables enterprises, small businesses, and entrepreneurs to develop, run, and scale software without technical expertise. Revo Capital, Turkey's largest VC firm, participated in Builder.ai's Series B round of $65 million announced in May 2021, aimed at scaling operations and enhancing platform capabilities. This followed a $29.5 million Series A in November 2018 led by Lakestar and Jungle Ventures. Subsequent rounds included $100 million Series C in March 2022 led by Insight Partners for international expansion and AI development, and a $250 million Series D in May 2023 led by Qatar Investment Authority, bringing total funding to around $430-445 million. Revo Capital, which also backed unicorns like Getir, focuses on early-stage tech in Turkey, Eastern Europe, and Baltics across sectors including AI and software.
Nov 2018Series AJungle Ventures (lead); Lakestar (lead); Deepcore; Tapestry VC$30M-Builder.ai was founded in 2016 as Engineer.ai and launched its platform in June 2018, offering a guided process to scope and build applications with assistance from a virtual assistant called Natasha. The company claimed early success with high-profile clients including BBC and Virgin, reporting approximately $24 million in revenue within six months of platform launch. In November 2018, Builder.ai completed its Series A funding round of $29.5 million, led by Lakestar and Jungle Ventures, marking an early stage of expansion. However, the company's claimed AI-driven development model masked a reality heavily dependent on manual work by human engineers, a discrepancy that would later contribute to its eventual downfall. The platform targeted the low-code/no-code software development market, positioning itself as a tool to democratize app building for non-technical users across industries including healthcare, financial services, retail, and education.
