Lovable hits $13.3B valuation on $400M Series C for AI app-building

Stockholm-based Lovable has closed a $400 million Series C at a $13.3 billion valuation, led by Menlo Ventures and co-led by EQT’s Scaleup Europe Fund. The round pulls in new backers across four continents — including Tencent and World Innovation Lab in Asia, Kaszek and LTS Growth in Latin America, and Balderton and Carmignac in Europe — alongside returning investors such as Accel, CapitalG, DST Global, and Salesforce Ventures. Coming barely eight months after a Series B in December 2025, the raise underscores how aggressively capital is chasing AI-assisted software creation.

Lovable’s pitch is to let non-engineers build and run production software from natural-language prompts. The company reports more than 60 million projects created since its November 2024 launch and roughly 900 million monthly visits to apps built on the platform, with reach into nearly two-thirds of the Fortune 500. Its stated roadmap leans on a ‘compounding loop’ that trains the system on which apps actually generate revenue or improve workflows, continued post-training of open-source models, and headcount growth to around 450, weighted toward machine learning, infrastructure, and security.

For a security audience, the notable thread is Lovable’s effort to get ahead of the obvious risk in letting anyone ship code: automatic and scheduled security scanning, per-app trust centers, governance and publishing controls, and an AIUC-1 certification it bills as the first security standard for AI agents. Whether those controls hold up as millions of largely non-technical builders push apps live is the open question — these traction and valuation figures are the company’s own, and the real test is the security posture of the software its users deploy.
