1. Shortlist by proof, not pitch decks
Any agency can put "AI-powered", "world-class" and a stock hero image on their site. Ignore that. Look for three concrete signals:
Live case studies. Real URLs you can click, not screenshots. Bonus if they explain the trade-offs, not just the wins.
Open-source or public code. A GitHub org with real contributions tells you more than any deck.
Named team, LinkedIn-visible. If the "team" section is stock photos, walk away.
