The three things we fix
Three reasons you're working harder than the business pays you for.
You're the bottleneck.
Nothing ships without you signing it off, answering it, or chasing it. The business can't grow any faster than you can work.
Admin's eating your week.
Your team is losing hours to chasing, reporting, onboarding, scheduling and paperwork that machines could do faster and more accurately.
Your dormant leads and forgotten quotes are worth six figures.
Customers you've already paid to acquire, sitting in a spreadsheet nobody's working. Real revenue, ignored.
We build you a Business Operating System.
Your BOS. Yours to own, ours to support.
Custom built around how your business actually runs — like an exoskeleton for your operation. Not configured. Not templated. Built.
- →Manages your entire operation, not just customers.
- →Three to five agents in your operation within twelve weeks.
- →Does exactly what you need and nothing you don't.
- →One integrated system instead of twelve apps held together with duct tape.
Your BOS, your name
Every BOS we ship gets its own product name inside the client's business. Cold Lava ships the system; you own the brand it runs under.
What twelve weeks looks like
Diagnose
Week 1
Operations audit. Every process mapped, every leak surfaced. You leave with a written audit document.
Build
Weeks 2–4
Three to five agents in your operation. Scope, timeline, cost locked before any code. Weekly demos.
Support & Evolve
Weeks 5–12
Specialist embedded with your team. Live dashboard tracking £ saved week-on-week against your hourly rate.
Rolling retainer
Week 12+
New agents added as new bottlenecks emerge. Same engineers stay with the system.
No pitch decks. No procurement cycle. No twelve-month discovery. You see progress weekly.
What you actually get
Twelve weeks. Four phases. A deliverable every step.
Locked scope, locked cost, locked timeline. Audit document by end of week one. Agents in your operation by week four. You keep the system, the code, and the engineer who built it.
Week 1
Diagnose
Half-day workshop on site or remote. Every process mapped, every leak surfaced.
Weeks 2–4
Design + Build
Scope locked, timeline locked, cost locked — before any code. Then short build cycles with weekly demos.
Weeks 5–12
Support & Evolve
A Cold Lava engineer embedded with your team. Weekly check-ins. Live dashboard tracking £ saved, week-on-week.
Week 12+
Rolling retainer
Same team that built it stays with it. No handoff, no relay, no specialist drift.
No pitch decks. No procurement cycle. No twelve-month discovery. You see progress weekly.

Each tile below opens the deep dive — the problem we solve, what we ship, and the live UI your team would actually use.
Recruitment Intake
Candidates onboard themselves before a recruiter touches them.
The problem
Recruiters spend their first hour with every candidate gathering the same five fields and chasing the same documents. Most of those candidates don't even meet basic eligibility. Hours wasted before a real conversation happens.
What we build
A messaging-channel intake agent. The candidate gets a custom link, opens it, answers a short conversational set of questions, uploads a passport or right-to-work doc, and the agent verifies it. By the time a recruiter sees them, they're already in the system with everything attached.
Result
Recruiter time only spent on candidates who pass first-pass eligibility, with documents already verified. Time-to-shortlist drops from days to hours.

From a director we built for
"Our sales reps can focus on selling whilst the AI system Cold Lava built for us is working on the follow-ups. The automated email sequences for scaffolding arrangements, reminders that their site visits are the next day — absolutely game changing. I can't tell you the amount of times we've had surveyors turn up and the customer has forgotten. Couldn't live without it.

Why us, not them
Six things that don't move.
Plain English, against the kind of agency this market is full of.
/ The typical "AI agency"
/ Cold Lava
Marketers who hire developers
Operators who code, founders who build
Outsourced delivery, offshore handoff
The founder writes the code
Audit team and build team are different teams
Same hands diagnose and build
"Support" means a paragraph in the contract
Same engineers, year three and beyond
AI replaces your people
AI multiplies what your best people already do
You are the experiment
We solved our own problems first
No pitch decks, no pressure.

Annual £ recovered

/ Your dashboard, week 12
LiveEvery agent in your BOS logs its runs. Hours recovered × your rate = £ saved, tracked week-on-week. You see the number move — or you don't pay.
