The product at a glance
GrowthForge — designed, built & operated by Lumina
AI-Powered Content Assistant
Solo founders, indie hackers, technical creators
Help founders publish high-quality content consistently, without spending hours writing
Solo founders know content matters — they just don’t have time to write it.
Solo entrepreneurs know the value of content marketing, but don’t have time to write blog posts every week.
Hiring a writer is expensive and slow to onboard on a niche product.
Generic AI tools exist, but their outputs don’t match the business’s niche or the founder’s tone.
An assistant that feels like a cofounder who understands the business and writes like them.
We designed and built an AI content assistant for solo founders and indie makers that helps them write blog posts that reflect their product and tone — grounded in their own site and past writing, not generic boilerplate. It’s a product we design, build, and operate end-to-end.
What it runs on
How it’s built
Three stages work in sequence: prompts built from the founder’s context, context injected from their existing content, and a multi-step workflow that lets them shape the draft at each stage.
Dynamic Prompting
Prompts are tailored to user preferences and business tone — built from ingested site content, past posts, and founder-supplied context.
Context Injection
Summaries of past content and niche details are injected at generation time via vector search, so every draft stays on-topic and on-brand.
Multi-Step Workflows
Content drafts → summary → CTA suggestions → tone/style polish. Each step is discrete, inspectable, and editable before moving forward.
The delivered product
