The short answer
Nuvenar is a UK engineering firm with two business arms. The first is a senior-only services team that takes paid engagements across seven disciplines. The second is NuvenarHub, a SaaS product for WhatsApp, CRM, calling, AI replies, and ad-spend attribution. Both arms run under the same legal entity, NUVENAR LTD, registered in England and Wales. The team operates remote-first on UK business hours.
The two arms in detail
1. Engineering services
Seven disciplines, one senior team, one invoice:
- Consulting: fractional CTO, technical due diligence, architecture review.
- Software development: bespoke web and mobile applications, internal tools, API integrations.
- AI and automation: LLM applications, RAG pipelines, workflow automation, AI agents.
- Cloud and hosting: AWS, GCP, Hetzner, Cloudflare, multi-region deployments.
- Cybersecurity: penetration testing, SOC2 readiness, security audits.
- DevOps and managed IT: CI/CD, observability, incident response, 24/7 cover.
- Digital marketing: paid growth on Meta, Google, TikTok with ~£240k a month in spend under management.
Engagements are scoped per project. Project work typically lands £10k to £500k + VAT. Retainers run £5k to £50k a month + VAT. Pricing is quoted in writing before anything starts and there are no hourly invoices.
2. NuvenarHub (the product)
NuvenarHub is a self-serve SaaS platform built for businesses that live on WhatsApp. It bundles WhatsApp messaging at scale, a full CRM with custom pipelines, Twilio-based calling with Whisper transcription and Claude AI summaries, an AI WhatsApp agent on Claude Haiku, marketing campaign tools, ROAS attribution from ad spend to booking to revenue, invoicing, accounting, and a 57-row feature matrix you can compare at /pricing.
Three tiers: Starter at £60 per month + VAT (solo practitioner), Pro at £480 per month + VAT (most clinics start here), Enterprise at £4,200 per month + VAT(multi-location, multi-workspace, dedicated CSM). No setup fee. 7-day free trial with card on file, charged on day 8. All prices are exclusive of VAT, third-party API usage is passed through at cost.
How Nuvenar is different from a normal agency
Three differences buyers notice in the first two weeks:
- Every engineer is senior. There are no junior teams hidden behind a project manager. Decisions get made in the same conversation by the same person doing the work.
- One invoice across the stack. You do not stitch together a software house, an AI shop, an SEO agency, and a security firm. One company, one contract, one accountable team.
- The team runs its own production SaaS. NuvenarHub is real revenue infrastructure with paying operators, not a side project. The same engineers who do client work also operate that platform daily, which means the patterns you get are battle-tested, not theoretical.

How to start
Two routes depending on what you need:
- Self-serve NuvenarHub: start a 7-day Pro trial, card required upfront, charged on day 8. Setup takes about ten minutes.
- Bespoke services: book a 30-minute discovery call. The first conversation is with the person who would scope and oversee the work.
