Build vs. Buy

WHY NOT JUST DIY?

Featured Case Study

HOW A UK INSURANCE BROKER WENT FROM 12 LEADS/MONTH TO 340

The Client

Mid-sized commercial insurance broker, West Midlands. $22m turnover, 40 staff. Served SME manufacturers and logistics firms across the UK.

The Problem

Their lead engine was a three-person SDR team cold-calling a bought list. 12 qualified leads a month on a good month. Cost per lead: $425. Two SDRs had quit in six months citing burnout.

What We Built

  • NOVA — LinkedIn + email, 4,200-contact decision-maker universe.
  • ARIA — 24/7 inbound qualification against 6 criteria.
  • HERALD — warm follow-up for the 60% who ghosted.
  • Full HubSpot integration. No rip-and-replace.

The Numbers — 90 Days

Testimonials

WHAT CLIENTS SAY

"Brutal honesty: I thought 'AI agency' meant more ChatGPT wrappers. First 30 days with Xiilio we booked 63 demos off cold outreach — we used to book 63 in a quarter. I've stopped asking how."

VP Revenue

Confidential SaaS Client — London

"We were nervous about an AI agent talking to our clients. Aria went live on a Tuesday. By Friday she'd handled 140 enquiries and the only complaint was one partner thought she sounded 'too young.' That's a problem we can solve."

Managing Partner

Confidential Law Firm — Leeds

"ROAS on our paid social sat at 1.8× for two years. Xiilio didn't change the creative — they rebuilt the targeting, the funnel and the post-click journey. Three months in we're at 4.4×. Spend hasn't moved. Revenue has."

Frequently Asked

QUESTIONS, ANSWERED.

The questions we hear most often from prospective clients — answered straight.

How fast can Xiilio deploy AI agents for my business?
We build and deploy most systems in 24 to 48 hours. Complex enterprise integrations can take up to a week, but you'll have live pipeline infrastructure running faster than any traditional agency can sign a contract.
Do I need technical knowledge to use Xiilio?
None. We build, deploy, and manage the entire system. You get weekly reports, a live dashboard, and a single point of contact. Your team focuses on closing the leads we deliver.
What kind of ROI can I expect?
Most clients see 200% ROI within the first month and 4× average ROAS on paid campaigns. Exact results depend on your industry, offer, and sales cycle — we'll model this with you on the first call before you commit to anything.
Is my data secure and GDPR compliant?
Yes. We run AES-256 encryption end-to-end, are fully UK GDPR and PECR compliant, and maintain records of processing activity for every client. Enterprise plans include a dedicated compliance review.
Where is Xiilio based?
London, UK with teams across the United States and Asia. We serve clients in 15+ countries. Full team roster and contact details are on the About page.
What happens if your AI agent says something wrong to my customer?
Every AI interaction is logged, reviewed and monitored. Aria, Nova and the rest operate inside tight guardrails — they can't make claims, quote prices or commit your business without human approval. If something slips, we catch it, fix it, and PI insurance is also in place; we share the certificate and cover amount on request during procurement.
Do I own the data and the AI agents you build for me?
You own your data, always. The agent configurations, playbooks and training are licensed for the life of your contract. On Enterprise plans, full ownership of custom agents transfers to you at 24 months.
What does the first 30 days actually look like?
Week 1: discovery, audit, target universe. Week 2: build and QA. Week 3: go live, soft launch, first optimisation round. Week 4: first full reporting cycle and strategy call. You'll have pipeline moving in week 2.
What if it doesn't work?
We run a 90-day minimum term because anything shorter isn't enough time to see meaningful data. If you hit 90 days and can't point to measurable ROI against pre-agreed KPIs, we'll work the next 30 days at no cost. We've invoked that clause three times in two years.
