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.

VECTOR Labs suits a European healthcare, pharma or manufacturing company that wants forecasting, computer vision or a first AI assistant from a Sofia data science team.
The main cautionMost of its Clutch record is general software outsourcing: 10 of 14 reviews date from 2020 under the Childish name, and none describes an agent or LLM build, so agent work rests on one case study.
