Capturing every opportunity?
Or are you missing value?

Opportunities don't arrive in one place — they show up in an inbox, a Granola note, a WhatsApp thread, a call transcript. If it doesn't make it into your system, it isn't lost, just invisible: a relationship that goes quiet, a deal that slips past, a fundraising opportunity missed.

I build the system that pulls everything together effortlessly, so every signal is captured, opportunities are surfaced and value compounds.

Bring everything you need together

What it looks like

A unified system that compounds value

You can be the firm that works its network harder than anyone else in the room - every relationship followed up, nothing left to go cold. The system compounds: each deal, each contact, each connection makes the next one easier to find.

Your firm, perfectly designed

Your interactions, your intelligence, your processes. I build you a bespoke system created for your firm. It's created in Attio; the fastest-growing AI CRM platform, but entirely customised to handle mandates, investors, startups, founders, fundraising or whatever you need.

Your insights, captured and surfaced

Every call, meeting, job change, investment round - capture it all, surface what matters and compound the value. I build your intelligence ecosystem, bringing in emails, call recordings, LinkedIn and WhatsApp and providing you with an intelligent map of opportunities and potential value.

Your team, effortlessly supported

The entire firm's insights and interactions flow into one central system, effortlessly. I help you make the most of AI and automated capture to bring everything together. Going beyond capture, I'll help you surface what's important and compound value for the long-term.

Who I help

Moving off another CRM?

How it works

Every engagement is different, so this is a shape, not a production line: one clear project to design and build your system, then support whenever you need it.

01

System design

I learn how your firm actually works and map the system before anything is built. Start with a free Initial Consultation, or a £500 Studio Session or Data Audit, credited if you go ahead.

02

Build and onboard

Bespoke, scoped to your firm: your data brought in, the stack integrated, automation and reporting built, and your team onboarded onto a system they will actually use.

03

On demand support

Studio Credits, used when you need them. Every project includes 2–8 for the three months after it completes. Top up, move to a quarterly plan, or simply stop.

Your questions answered.

Do I need to be on Attio already?

No. I work with firms already in Attio and firms moving from somewhere else - Affinity, DealCloud, Salesforce, spreadsheets. If you're migrating, that's built into the project, not a separate step.

How does it compare to other systems?

Generic CRMs (Salesforce, HubSpot) are built for everyone, so you end up bending your process to fit the software. Legacy dealmaker platforms are built for deal flow but feel dated and aren't AI-native. And spreadsheets work until they don't - no automation, no single source of truth. What I build is different: a system shaped around how your firm actually works, on a platform built for the AI era, set up by someone who understands dealmaking - not a generic implementation.

Why Attio, and do you only build on Attio?

Attio is the fastest-growing AI-native CRM, and it's flexible enough to be shaped around how your firm works rather than the other way round. I build almost exclusively on Attio, with the rest of your stack - AI, automation, data - wired in around it.

How much does it cost?

It depends on the size and shape of your firm, but typical builds are £2,500-5,000. I usually start with a Studio Session or Data Audit, at £500, credited back against your build. I also offer on-demand support to maintain and upgrade your setup. A free 20-minute call will get you an estimate and an expected timeframe.

How long does it take?

Most builds run 1-4 weeks depending on your data - straightforward setups in 1-2 weeks, typical builds in 2-3, and larger or more complex migrations in 3-4.

How do you handle our data and confidentiality?

Every engagement starts with an NDA, and I carry £1m professional indemnity and cyber insurance. Your data and your deal flow are treated with the same discretion I'd want for my own.

I’m not technical – is that a problem?

Not at all - that's what I'm here for. I handle the build end-to-end; you just need to know how your firm actually works, and I'll translate that into the system.

What happens once it’s built?

Every project comes with Studio Credits - a pool of support you can draw on for three months after launch, for tweaks, training or new workflows. After that, credits top up or roll into a quarterly plan, so the system keeps pace with your firm.
