Hackmamba is a developer marketing agency for technical products, covering strategy, technical content, documentation, DevRel, paid media, and influencer marketing. Its work is organised around a Developer Adoption Architecture that maps the developer journey from first discovery through evaluation, integration, advocacy, and compounding efficiency. Services include technical tutorials and guides, API references and onboarding flows, Mintlify-based documentation builds, community and hackathon programmes, DevRel audits, and developer-focused paid campaigns. Clients include OpenRouter, Actian, Cloudinary, Celo, and Netlify.

PromptBase is a marketplace where creators sell ready-made prompts for popular AI models. Instead of guessing wording from scratch, you browse a category, preview sample outputs, and buy a prompt that already produces a specific style or effect in tools like Midjourney, DALL-E, Stable Diffusion and ChatGPT.
