We brought Hackmamba on at a chaotic moment in our documentation work, and David proved to be a reliable, fast-learning partner through it. He came up to speed fast on a difficult and rapidly evolving subject area, stayed responsive, and helped us stay afloat during a demanding transition. We were grateful for the support when it counted

Hackmamba are great at driving content strategy from inception to execution, and they are very reasonable on pricing. A great fit for an early stage dev-tools startup!
