Our
capabilities
Bespoke AI wherever your business needs it. Each one is designed around your workflows and connected to the tools you already use.
Discuss your projectBusiness automation
Administrative tasks, workflows, reporting and document processing handled automatically, with people approving anything that matters.
For example: invoices and contracts read, checked and filed into your systems.
AI sales & marketing
Lead generation, CRM automation, personalised outreach, content creation and marketing workflows your team approves.
For example: companies showing a buying signal, researched and queued for a tailored email.
AI voice agents
Intelligent receptionists, automated calls, customer support and appointment scheduling, handing over to a person when it counts.
For example: out-of-hours calls answered and booked into your calendar.
AI recruitment solutions
CV processing, candidate management, CRM integration and interview coordination. See Clerkwell, our own recruitment product, below.
For example: every applicant ranked against the role, with the proof from each CV.
AI financial solutions
Automated reporting, document analysis and operational tools for financial firms and family offices.
For example: statements from several providers consolidated into one monthly report.
AI integrations
Connecting AI with your existing software, databases, CRMs and communication platforms, so it works inside your tools rather than beside them.
For example: calls transcribed, summarised and written into the right CRM record.
Why bespoke
Off the shelf fits nobody quite right
Most businesses choose between software that makes them work its way, or the cost and time of hiring their own developers. A bespoke build with a long-term partner sits between the two.
Off-the-shelf software
You change to fit the tool
- Built for the average customer, not for you
- Another login that doesn't talk to your other systems
- Features you pay for and never use
- Spreadsheets and workarounds fill the gaps
An in-house team
Months before anything ships
- Recruiting, salaries and management overhead
- AI expertise is scarce and expensive to hire
- Knowledge leaves when people do
- Hard to justify for one or two systems
Sartor

- Designed around how your people actually work
- Connected to the systems you already use
- Specialist AI expertise from day one, at a fraction of the cost of your own team
- Maintained and improved after launch

Our work
Here's one we built from scratch
Clerkwell is our own product for recruitment agencies. It shows the kind of bespoke AI software we build: practical, measurable, and with people in control.
Clerkwell
Recruitment agencies lose hours reading CVs and forget the candidates already in their database. Clerkwell reads every CV, ranks applicants with the evidence for each score, finds placements in the agency's existing database, and books meetings with companies that are hiring.

Questions
Before you get in touch
How is this different from a software agency?
Most agencies build what you ask for and move on. We start by understanding your operations, recommend what's worth building, build it to fit your existing systems, and then stay to run and improve it.
We already have software. Do we need to replace it?
Usually not. Most of our work connects to and extends what you already use: your CRM, databases, inbox, accounting and communication tools.
How long does a project take?
It depends on what we build. A focused automation can be live in a few weeks; a larger bespoke system is delivered in stages, so you see working software early.
Do we need technical staff?
No. We handle design, development, hosting and support. You need someone who knows how the work is done today, and a little of their time.
Is our data safe?
We sign a data processing agreement before we touch anything, use the least access we need, keep data in your systems where possible, and design every system so a person approves decisions about people.
What does it cost?
Discovery is a fixed fee. Each build gets a fixed project price, and ongoing support is a monthly fee. You'll have the numbers for each stage before you commit.
