What Plinth does

Plinth, operated by UK private limited company Time to Spare Ltd. (Companies House Reg. No. 11530023) and headquartered in London, is an AI-powered software platform that helps UK charities, community foundations, local authorities and frontline non-profits deliver, measure and fund community impact. The unified platform bundles grant management, case management with voice-to-case-note transcription, bookings and events, room hire, surveys, partner CRM and referral networks, volunteering, payments, and an AI stock tracker, all sharing a single data model and login. Underlying infrastructure runs on Google Cloud Platform in europe-west3 with UK/EU data residency, fronted by Vercel, with GDPR compliance and an explicit no-train-on-customer-data AI policy. AI is embedded across the product surface through natural language processing for grant scoring and personalised applicant feedback, Gemini-powered speech transcription with speaker diarisation for case notes, a multimodal computer-vision pipeline for inventory and condition tracking, AI-generated surveys, document-to-room setup, and a proprietary research agent ("Agent Pippin") that queries live platform data and produces branded impact reports in 26 languages.

The platform employs a hybrid go-to-market. Small charities and CICs self-serve on a permanent free tier covering core modules, with upgrade prompts into monthly subscriptions (£20–£1,250/month based on report/query usage, no per-user pricing). Enterprise customers — community foundations, large charities, housing associations and local authorities — buy annual contracts via a sales-assisted motion with 30-minute demos and tailored ROI presentations. Dedicated grant-management tiers run £5,000–£15,000 per year, and local authorities buy multi-programme deployments starting at £15,000 per programme down to £7,500 per programme at six or more programmes. Payments are monetised through Stripe Connect with a 5% + £0.50 per-transaction fee. The company claims 1,500+ community organisations and 60+ funders using the platform, mediating £200m+ of annual grant making, with a 12-person specialist team and 8 years of operating history.
