# Sentry Digital Services > Sentry Digital Services builds growth-stage businesses (typically £5m–£100m turnover, B2B or B2C, any sector) a connected, accountable revenue system — a "Growth & Control Engine" combining RevOps, data, automation and AI. Engagements are value-engineered and measured against a financial value model. Founder and senior point of contact: Jason Orrock. Contact: value@sentrydigitalservices.com, 01738 506283. ## What Sentry does Sentry diagnoses the constraints holding back growth, then builds and manages a connected system that protects existing value, improves performance, and creates new growth — measured at every step. The approach is value-first and outcome-accountable: every engagement starts with a free, no-obligation Discovery session and a Financial Value Model before significant investment. Methodologies include DMAIC (improve what exists), DMADV (design what's new), and a five-level operating maturity model. ## Ideal client Growth-stage businesses, ~£5m–£100m turnover, 50–500 employees, often without internal technology leadership, with real demand not yet converting its full potential. B2B (ideal customer profile) and B2C (segmentation). ## Managed services - [Digital Marketing Manager & Growth Engine](https://sentrydigitalservices.com/services/digital-marketing/): paid media + owned email as one system, accountable to pipeline and ROAS. - [Digital Ads](https://sentrydigitalservices.com/services/digital-ads/): paid media across every channel, measured on revenue. - [Email Marketing](https://sentrydigitalservices.com/services/email-marketing/): campaigns, automated flows, segmentation, deliverability. - [Digital Voice](https://sentrydigitalservices.com/services/digital-voice/): AI voice/chat agents that answer, qualify and act live, 24/7. - [Twilio Flex Voice & AI](https://sentrydigitalservices.com/services/twilio-flex-voice-ai/): Twilio Flex built and managed as an AI-first contact centre, with human handover carrying full context. - [Asterisk Voice & AI](https://sentrydigitalservices.com/services/asterisk-voice-ai/): open-source Asterisk telephony, managed, with AI voice agents in front and no per-seat licensing. - [3CX Voice & AI](https://sentrydigitalservices.com/services/3cx-voice-ai/): 3CX deployed and managed with AI voice agents answering, qualifying and acting on calls. - [Agentic AI](https://sentrydigitalservices.com/services/agentic-ai/): autonomous agents that reason, decide and act under governance. - [Automation & Integration](https://sentrydigitalservices.com/services/automation-integration/): connect systems and eliminate manual work (built on n8n). - [Data & Data Analytics](https://sentrydigitalservices.com/services/data-analytics/): a unified data warehouse — the single source of truth. - [Lead Generation Engine](https://sentrydigitalservices.com/services/lead-generation/): market sizing to qualified pipeline (BANT/MEDDIC). - [Website Managed Services](https://sentrydigitalservices.com/services/website-managed/): headless on Astro + Cloudflare, or managed standard CMS. - [Ecommerce Services](https://sentrydigitalservices.com/services/ecommerce/): Shopify, WooCommerce, BigCommerce, Magento or headless. ## Key pages - [Services overview](https://sentrydigitalservices.com/services/) - [Blueprints](https://sentrydigitalservices.com/blueprints/): proven solution accelerators. - [Technology](https://sentrydigitalservices.com/technology/): platform-agnostic; technology selected last. - [Value Engineering](https://sentrydigitalservices.com/value-engineering/): DMAIC, DMADV, the five-stage value cycle, Enterprise Value Pyramid. - [Growth Framework](https://sentrydigitalservices.com/growth-framework/): the 10-constraint diagnostic, cost of inaction, KPIs by department. - [Customer Intelligence](https://sentrydigitalservices.com/customer-intelligence/): market sizing (TAM/SAM/SOM), targeting, personas, RFM. - [How We Work & Pricing](https://sentrydigitalservices.com/how-we-work/): engagement modes; managed service from £3,000/month. - [Who It's For](https://sentrydigitalservices.com/who-its-for/): six honest signals of fit. - [Discovery & Blueprint](https://sentrydigitalservices.com/discovery/): the 14 structured commercial outputs. - [About](https://sentrydigitalservices.com/about/) · [Insights](https://sentrydigitalservices.com/insights/) · [Contact](https://sentrydigitalservices.com/contact/) ## Pricing Managed service from £3,000/month, scope-based, selected tool costs included.
