Henry Bassey, Developer Marketing and AI Automation Consultant

Developer marketing for AI and infrastructure companies

I’m Henry. I lead developer marketing at Hackmamba. My work for Actian VectorAI DB has reached over 5 million developers.

I started as a developer, moved into marketing, and found that the best work happens between the two. Along the way, I earned an MBA from Quantic (full scholarship, thank you). Each chapter below is one piece of my work.

Tools as marketing · Actian VectorAI DB

Free tools developers could use without talking to sales.

The sizing calculator. Sometimes it tells you to skip the vector database.

The Actian VectorAI DB sizing calculator. For a workload of 100,000 vectors, its verdict reads: You don't need a vector database yet.

AI workflows

An AI-assisted content-intelligence workflow.

It turns signals from GitHub, Stack Overflow, Reddit, Hacker News and industry coverage into sourced briefings and content opportunities.

I also build agentic workflows that turn scripts into animated videos and create graphics.

Make something useful

What if the marketing was a tool?

Leading developer marketing for Actian VectorAI DB

I joined the Actian VectorAI DB launch as content lead. After launch, the work started moving in silos.

I was promoted to developer marketing lead on the account and brought content, paid media and community under one plan. Part of that plan was building free tools developers could use without talking to sales. When our messaging moved on, I also rewrote and rebuilt the product landing page so the website and social said the same thing.

Run the full funnel

A useful tool still has to be found.

Paid and organic growth for developer tools

For Actian, I ran paid media with Tahir Mohammed, from X ads and newsletter sponsorships to influencer partnerships.

On the organic side, an Actian article on vector database pricing reached Google’s first page and AI Overviews within seven days. I also led content for OpenRouter, whose blog passed 110,000 organic clicks in 126 days.

Client spotlight

ZenRows

Content strategy, technical SEO and AI-assisted research

I’m helping reposition ZenRows as web data infrastructure for AI. The work started with finding out why traffic had dropped. I led the content work across competitor comparisons and practical agent tutorials, and researched how ZenRows appeared in AI-generated answers.

7,000+
blog search clicks, up more than 50%

Give the work a system

The fix wasn’t another piece of content.

Developer Adoption Architecture

Hackmamba was known for technical content, but the work had grown into launches, communities, paid media and events.

Across our client work, one stage of the developer journey kept being left to chance. So I built the Developer Adoption Architecture and led Hackmamba’s rebrand into a full-cycle developer growth agency.

How the Developer Adoption Architecture works

Teach the system to write

Good writing shouldn’t depend on luck.

A technical writing skill for people and AI agents

I’ve edited hundreds of technical articles. The good ones have a clear point, a logical flow and code that backs up every claim.

So I wrote down what makes them work and turned it into an open-source skill for writers and AI agents. It later fed into Boki, Hackmamba’s content system.

The Xamfonos/technical-writing-best-practices repository on GitHub: a Claude Code skill for technical content, with 26 principles across 5 domains and an MIT licence.

Take it on stage

I test these ideas on stage, too.

Talks and panels on developer marketing

A framework only proves itself when you explain it to real people.

I’ve spoken at The Builders Summit in Lagos and AI Summit in Uyo, and joined conversations on Reo.Dev’s DevGTM series and the DevRel Compass panel.

Ask a question closer to home

I do this from Lagos.
What does that change?

Developer marketing in Africa and the diaspora

Does developer marketing work the same way in Africa? And for which tools?

I work from Lagos, mostly for companies based elsewhere, so this question is hard to ignore. I’m turning it into open research for builders and investors.

How can humans and AI agents make better strategy decisions in this AI era?

I’m turning business strategy frameworks into tools humans and AI agents can use to make better decisions. It’s called OpenStrategy (formerly Marketing Console), and it’s still being built.

    William via Discord

  • I read one in the middle of the night one time and I felt the holy ghost. It was too good. It’s amazing how he’s able to create awesome work in a rigid space like tech. He writes with so much grace, like he’s floating. I could talk about his work all day. It mesmerizes me.

    Praise James via Discord

  • I used to struggle with creating a compelling intro, but when I read the edits he did on one of my project. I got more insights for other tasks.

    Emilson via Discord

From the Hackmamba Discord (unprompted)

  • Muyiwa: “I was reading @Xamfonos content today and all I can say is DAMN 😄”
  • Benye: “Me everytime I read his work”
  • Muyiwa: “It’s all interesting. Like you start and you just continue.”
  • Praise James: “It reads like a song”

From readers and listeners

  • I know you’re probably been told this a lot, but you’re so good at writing. Your writing reads like a song. When someone starts, they don’t know when they finish. I wonder the years of experience it took to attain such next-level writing. I hope you never stop writing because people like me will never stop reading your work.

    Reader via LinkedIn

  • I read some of your work on Hackmamba’s blog and 🔥🔥🔥 Your storytelling is amazing and your writing is so clear and easy to follow. How did you become this good?

    Reader via DM

  • The insights you shared in the video were genuinely strong and thoughtful. They added a lot of depth to the conversation and made the content truly valuable for the audience. I also really appreciate the effort you and the team put into distributing the video across channels. That amplification made a meaningful difference.
