From $25kDirectory figures only: Clutch shows a $25,000+ minimum and $150-$199 an hour, though its most common reviewed project is under $10,000. Publishes no prices on its own site, which says a proof of concept typically runs 2-3 months.
Best forA UK or Irish mid-market company that wants help choosing and rolling out Claude, Copilot or Gemini, starting with a discovery priced at £2,000 to £12,000.
Softblues suits a UK or Irish mid-market company that wants help choosing and rolling out Claude, Copilot or Gemini, starting from a discovery engagement priced on its own site.
The main cautionOnly 2 of 32 Clutch reviews concern AI work, both from late 2025; the other 30 describe the web and WooCommerce business it was from 2020 to 2023, so the 5.0 rating says little about AI delivery.
