## Hackmamba

Hackmamba is a developer marketing agency that works with infrastructure, API, and developer-tool companies. Its premise is that developer adoption follows a specific funnel — qualified attention, self-service conviction, rapid adoption, organic advocacy, and compounding efficiency — and that most companies lose developers somewhere in the middle because either the content lacks technical depth or the documentation cannot carry someone to a working integration. Its Developer Adoption Architecture maps those five stages to six disciplines so a programme can be planned end to end.

The six disciplines are strategy and leadership, technical content marketing, technical documentation, developer relations, paid media, and tech influencer marketing. In practice that means technical tutorials and guides, GEO-aware SEO, getting-started flows and API references (Mintlify documentation is a named service), community and hackathon programmes, DX audits, and paid campaigns aimed at developer activation rather than generic reach. The agency positions itself as an embedded extension of client teams rather than an outside vendor.

Hackmamba publishes concrete results rather than vague claims: 49,139 organic clicks in three months for OpenRouter across 39 technical articles, a 46% increase in lead-to-SQL submission rate for Lumana, a 50% reduction in integration time for Celo after a documentation restructure, and a programme that helped Actian's VectorAI DB reach over 1M developers. It reports publishing 1,700+ pieces and influencing more than $400M in pipeline, with clients including Cloudinary, Auth0, appwrite, Netlify, and Sourcegraph.

**Pricing & Plans:** Pricing is not published. Engagements are scoped after a discovery call, with rates quoted per programme based on content volume, channels, and duration. A free planning playbook is offered as a starting point.

- **Technical content marketing:** Tutorials, guides, thought leadership, video content, and GEO-friendly SEO that meet developers at the moment they are searching for a solution.
- **Documentation and onboarding:** Getting started flows, API references, restructures, and Mintlify builds designed to shorten time-to-first-working-build and cut support tickets.
- **Developer relations and DevRel:** Programmes spanning developer community, education, champions, hackathons, and DX audits to drive real adoption rather than raw signups.
- **Paid media for developer audiences:** Paid campaigns and PPC built around developer activation, wired to the same journeys as the organic content.
- **Developer Adoption Architecture:** A five-stage framework that ties discovery, evaluation, integration, advocacy, and compounding efficiency into one governed programme.

**Strengths:** Narrowly specialised in developer audiences rather than general B2B marketing; Covers the full funnel instead of just content or just paid; Documentation capability, including Mintlify builds and full restructures; Named clients and published performance numbers rather than generic claims

**Limitations:** Pricing is quoted per engagement, so costs are not transparent up front; Best value for companies already investing seriously in developer growth, not tiny teams; Agency engagements require internal time for briefs, reviews, and product access; Results depend heavily on how much product documentation and access you can give them
