Sparkles is building Lovable for large existing codebases.

Everyone is using coding agents now, but many teams are still stuck relying on outsourced development agencies, and it can take weeks to turn an idea into something live in production.

Sparkles is building the AI workflow for teams shipping changes to existing products. We’re making it possible for product, design, marketing, and ops teams to safely make real changes to production codebases through GitHub-native workflows, reviewable pull requests, and the right guardrails.

Sparkles was founded by Dan, who dropped out of University College London and previously worked with the former CTO of Monzo at Iterate.com. We raised $3.5M, backed by Y Combinator, Moonfire Ventures, and angels from OpenAI, Anthropic, a16z, General Catalyst, Cloudflare, and others.
