Private practice · London
Now booking · 5-client capEveryone’s buying AI. It knows nothing about your business.
Northrope fixes that. We run your commercial back office on AI agents that learn your business — inbox triaged, promises tracked, invoices chased, one live page of truth — so the admin runs itself while you keep the judgment.
Run by Natan Acosta — ten years across commercial operations and sales. The same system runs the back office of a London media company today.
Live in 30 days, and you can leave any month with your data and setup intact. The call is twenty minutes — no deck, no follow-up sequence.
- 14 emails read & filed overnight inbox
- 3 new promises → ledger tracked
- 2 invoices overdue · chases drafted approve
- 1 commitment due today · reply drafted approve
- Cash position · live on your page updated
What lands on your desk each morning, once we’re running it.

The founder’s daily part
Why now
When everyone has the same intelligence, the advantage is what it knows about you.
Models are abundant and getting cheaper every quarter. Three things are getting scarcer:
01
Context
AI knows everything except who promised what, who owes you money, and what “urgent” means in your company. We build that layer and keep it live — structured, current, machine-readable.
02
Trust
Generation is free; checking is the bottleneck. You decide what runs automatically and what waits for your sign-off — with an audit log on every write and a one-click kill switch.
03
Compounding
A chatbot subscription is a cost. A system that learns your business every week is an asset — one we keep compounding for as long as we run it, with no lock-in: leave any month and your data and setup come with you.
Who this is for
Founder-led, 5–50 people, run on email.
Industry doesn’t matter — if your business runs on email, invoices and promises, we can run it. Here’s the shape of the change:
Now
- Your inbox is the company’s to-do list
- Promises live in your head
- Invoices get chased when someone remembers
- Only you can see the whole picture — at 11pm
With Northrope running it
- Every email read, filed and mined for asks
- Every promise in a ledger with an owner and a date
- Overdue invoices chased automatically — or queued for your sign-off, your call
- One live page of truth, plus a five-minute briefing
What we run
Five systems and a safety net. The back office we run for you.
Set up in your own accounts, tuned on your real data, operated by us. AI does the reading, filing and chasing; you keep the judgment and the kill switch.
Inbox triage
Every email read, classified and filed — in your inbox, in lockstep. Asks and promises extracted, nothing falls through.
Promise ledger
Every commitment made or received, tracked with an owner and a date — and closed automatically the moment the reply goes out.
Cash chase
Overdue invoices detected in your accounting system; polite, escalating chases sent on the schedule you set — or queued for your approval. Your call.
The live page
One auto-refreshed page of truth: cash, who owes what, open loops, calendar, red flags. The whole company at a glance.
Morning briefing
Before 9am, every weekday: what landed, what is due, what to approve. Your day starts decided, not discovered.
Watchdogs & audit log
Alarms that catch silent failures, and a record of every write the system makes. Trust is a feature, not a promise.
Proof
The system already runs a real company.
This isn’t a pitch for software that doesn’t exist yet. What we run for clients is the same system in daily production. Specifics are anonymised; a live anonymised walkthrough is shown on the intro call under NDA.
London media company — live since April 2026
The full back office, running every weekday: each inbound email read, classified and filed in lockstep with Outlook; every ask extracted into a tracked ledger and auto-closed the moment a reply goes out; overdue invoices flagged with polite chase drafts ready each morning; one auto-refreshed page of cash, open loops and calendar; a watchdog that flags silent failures before anyone notices. Built and operated hands-on by me.
D2C food & logistics scale-up
Owned a 60-person ops and customer-service function delivering 15,000+ orders a month. Workflow redesign, dashboards and forecasting took on-time delivery from 87% to 97% and absorbed 30% volume growth without new headcount.
B2B decision-intelligence startup
Partnered with the CEO across strategy, revenue and operations. Built the outbound motion from scratch — CRM, enrichment, sequencing, dashboards — and supported fundraising through to diligence.
The offer
One engagement. No lock-in.

The maths, against the alternatives
Hire an ops manager
£35–45k/year
Plus two to three months to find them — and the process knowledge walks out the door when they do.
Automation agency
£2–5k/month
Open-ended retainer, and they own your plumbing — the incentive is to never be finished.

Method
From zero to running, week by week.

Week 1
Map
Access and accounts, then the real flows: how email actually moves, who promises what to whom, how invoices get raised and chased today, what "urgent" means in your company. The map decides the tuning.
-
Weeks 2–3
Install
The five systems go live on your real data. Tuned until the filing matches how you’d file it and the drafts sound like you — not like a robot doing an impression of you.
-
Week 4
Go live
Runbooks, alarms and a kill switch in place. We take the wheel and operate it daily; your team learns the five-minute routine: read the briefing, clear the sign-offs, done.

Founders don’t drown in strategy. They drown in email, chasing money, and remembering who promised what.
About
Run by Natan Acosta.
Northrope is a private practice run by one person. No team underneath, no junior associates billing your account — the person on the intro call is the one who builds and runs your system.
Ten years across commercial roles in venture-backed and bootstrapped UK companies. Seven in B2B sales — building and managing teams, designing outbound playbooks, generating eight-figure pipeline. Three as a Founder’s Associate inside early-stage companies — running a 60-person operations function in D2C food and logistics, then building outbound and supporting fundraising at a B2B decision-intelligence startup.
AI and automation work began in 2022. Since 2026 it has been the whole job: designing and operating the AI back office of a London media company — the system this practice runs for its clients.
The practice operates with a hard cap of five active clients. Engagements start with a 20-minute call and a 30-day onboarding. After that, only if both sides see a fit.
On the call you’ll get references and a live anonymised walkthrough of the system under NDA. If the first thirty seconds don’t land, we don’t proceed.
FAQ
Things people ask before the first call.
What if I need something that isn't on this page?
Bring it to the call. The five systems are the spine, but every business has one strange thing — a report nobody has time to build, a portal that needs checking daily, a workflow held together by one person’s memory. Adding those to what we run for you is exactly the point; bigger one-off builds can be scoped alongside.
Is this just ChatGPT wrappers?
No. It’s a system of record with AI in the loop: classifiers that read and file your email, a ledger that tracks every promise made and received, scheduled jobs that chase invoices and write your morning briefing, alarms that catch silent failures, and an audit log on every write. You’ll see a live anonymised system on the intro call — not slides.
Can AI really be trusted with our email and invoices?
It works to guardrails you set. You decide what runs automatically and what waits for your sign-off — money going out and brand-new outbound can always need approval. Every write is audit-logged, you have a one-click kill switch, and the level of autonomy is whatever you’re comfortable with — dial it up as trust builds.
What about our data?
Everything runs in your own accounts — your inbox, your accounting system, your storage. Nothing is used to train anyone’s models, access is revocable by you in one click, and a mutual NDA covers the engagement from the first call.
What does it cost?
One monthly fee, scoped to your business — it depends on what we’re running and how much of it. Less than an ops hire, with no recruitment, no management overhead and no lock-in. You get a fixed monthly figure on the intro call, and you can cancel any month.
Why not just hire an ops or admin person?
£30–45k a year plus management overhead — and the work itself is corrosive, so good people don’t stay in it. We run the reading, filing, chasing and remembering. Your people keep the judgment calls, which is the part humans are actually good at.
Why not Zapier or an automation agency?
Trigger-wiring breaks the moment reality gets messy — a forwarded thread, a half-promise, an invoice disputed politely. This is a judgment layer: classification, extraction and drafting with a ledger underneath, run as infrastructure with alarms and logs. And there’s no lock-in — cancel any month and everything we’ve built leaves with you.
