LOADING BRIEFING...
Every firm gets its own dedicated database server in London, up to 60 staff logins, and custom-built workflow agents — for less than the cost of a single junior administrator.
We never mix your firm's documents inside a shared database. Both plans give your practice its own 100% dedicated, single-tenant database server in London and hands-on 4-day setup by our senior architects. Choose Core for firms up to 60 staff, or Sovereign when you want your own private AI compute machines as well.
Your own dedicated London database server, private AI workspace, and 2 custom-built workflow agents for established practices of 15 to 60 staff.
Complete hardware isolation with both a dedicated database server and your own 100% dedicated private AI compute machines. Built for larger or strictly regulated practices.
Adjust the sliders below to see your exact upfront setup fee and fixed monthly retainer. There are no per-word usage meters or surprise month-end bills.
Your Sentivox Core retainer includes up to 60 staff at no extra per-person cost. Extra team members above 60 are £15/month each.
Your plan already includes 2 custom workflow agents. If you would like our engineers to build additional digital assistants for other departments, each extra agent starts from a £1,000 one-off build fee and £225/month for ongoing hosting and support.
See how custom workflow agents work on our Agents page →Firms looking to adopt AI across accounting, surveying, wealth management, M&A advisory, or legal work generally face three choices.
| What to Compare | Option 1: Public Cloud AI (e.g. Copilot / ChatGPT Team) | Option 2: Buying Your Own Servers & Hiring Engineers | Option 3: Sentivox Turnkey Private Systems |
|---|---|---|---|
| Monthly Cost & Predictability | ~£1,800/mo for 60 seats (£30/person) for chat only, plus £30k–£50k in consultancy fees to tidy up old shared folders beforehand | £100,000+ in upfront server hardware and a £75,000/yr specialist IT salary to keep it running | £1,450/mo (Core) or £3,950/mo (Sovereign) flat retainer with 60 to 150 staff and custom workflow agents included |
| Internal File Privacy (Who Sees What) | High risk — searches across messy old shared drives, risking junior staff seeing partner pay or confidential client files | Requires months of manual IT programming to set up and maintain safe folder rules | Staff only ever see the specific client folders and vaults their job role permits |
| Reading Complex Accounts & Leases | Chops pages into blind snippets—breaking tables in trial balances, tenancy schedules, and contracts | Requires months of custom programming to read complex tables and layouts accurately | Reads full pages visually so spreadsheets, schedules, and footnotes stay whole |
| Who Holds the Master Key | The software provider holds the keys on shared public servers | You manage physical servers in your own office cupboard and carry the maintenance burden | Your firm holds the sole master key in your own Microsoft or Google account inside UK clean rooms |
| Getting Started (No SharePoint Clean-Up) | Requires 3 to 6 months of archiving and reorganising old SharePoint folders before you dare switch it on | 6 to 12 months of internal building before your team can use it | Live in 4 days — create clean, dedicated vaults for active projects and templates in 90 seconds |
| Ongoing Engineering & Support | Generic chat tool only; nobody builds workflows around your firm’s actual checklists | Key-person risk if your internal engineer leaves or falls behind new AI models | Senior systems architects build and maintain your custom agents as part of your retainer |
Sentivox never replaces your outsourced IT support company (MSP) or internal IT team, and we never touch your staff laptops, office firewall, or Microsoft 365 licences. Your IT provider simply joins us for a single 20-minute setup call to link your web address, connect your normal Microsoft or Google staff logins, and hold your master key - while our architects handle 100% of the ongoing AI system support.
Clear, practical answers to the questions most frequently raised at partner and board meetings.
Both plans give your firm its own 100% dedicated, single-tenant database server in London with your own master encryption key. Sentivox Core (£1,450/mo) includes up to 60 staff and 2 custom workflow agents, running its AI brains inside sealed UK clean rooms. Sentivox Sovereign (from £3,950/mo) includes up to 150 staff, 4 custom agents, and your own 100% dedicated private AI compute machines with zero shared hardware.
No technical preparation or written specification is required beforehand. Meet directly with a Sentivox Senior Systems Architect (alongside your MSP or IT Director if desired) to review your regulatory boundary, select between Core and Sovereign isolation, and map your initial operational workflows.
