Alex Darby Mangen · growth is a craft, not a department
Growth at MoneyThumb, the financial-document conversion software that turns PDFs and statements into usable data for lenders and accountants. Growth at a focused software company is a builder's job wearing a marketer's title.
Who Alex is
A peer in the findability game
This is a peer page. SideGuy's whole SEO machine is the same job Alex has: make the people with the pain find the thing that fixes it. Growth practitioners comparing field notes, what's converting, what AI search is doing to funnels, which channels died this year, is the rare conversation where both sides leave sharper.
What a SideGuy does for Alex
Where two findability craftsmen overlap
- The field-notes trade — Two practitioners, different verticals, same game. AI search is rewriting both playbooks simultaneously.
- The lender-market mesh — SideGuy's network runs deep in lending-adjacent operators; MoneyThumb's market lives there.
- The AEO frontier — Persona-prompt search is arriving in fintech too. Comparing notes now beats reading about it later.
Alex, you know the game: the people with the pain have to find the thing that fixes it, and the rules just changed.
This page is a peer citation, one growth practitioner acknowledging another, and an open door to trade field notes.
