A small advisory firm for owners who’ve outgrown “we’ll sort it later.” We sit alongside you — strategy, operations, the unglamorous middle — until the business runs the way it should.
No decks for the sake of decks. We’re hired to make the next quarter simpler than the last — and to leave you with something that keeps working after we’ve gone.
Before we touch anything, we map how money, people and time actually move through your business — not how the org chart says they do. Most of the wins are hiding in that gap.
Processes, hand-offs, the spreadsheet three people secretly rely on. We rebuild the operational core so the day-to-day stops depending on heroics and late nights.
Advice is easy to give and hard to land. We stay close through the messy part — implementation — so a good plan becomes a change you can actually see on the P&L.
Siley Advisory began the way a lot of good businesses do — with someone who’d spent years quietly fixing other people’s operations deciding to do it properly, and on their own terms.
We’re deliberately small. That’s not a limitation, it’s the point: you get the person who scoped the work doing the work, not a graduate you’ve never met and a monthly invoice you can’t explain. We take on a handful of owners at a time, from a desk just off the M27, and we treat their numbers like they’re our own.
Most of our clients are Hampshire businesses turning over between half a million and ten — the awkward, brilliant stage where the founder is still the bottleneck and the systems haven’t caught up. That’s exactly the room we like to be in.
Straight talk, sensible fees, and someone who picks up the phone. — The team at Siley Advisory, Hedge End

If it only works because you’re holding it together, we haven’t finished.
Every engagement is fixed-scope with a clear deliverable and a flat fee agreed up front. Prices below are starting points — we’ll confirm yours after a short, free scoping call.
A full day in the room with you and your key people. We leave with a one-page plan, three named priorities and an honest read on what’s working — and what’s quietly costing you.
We follow a job from enquiry to invoice and map every hand-off, delay and duplicate. You get a prioritised list of fixes, ranked by effort against payback — no jargon, no filler.
A standing seat at your table. Monthly reviews, a plan we hold you to, and someone at the end of the phone between meetings for the decisions that can’t wait.
We design and document the operational spine of your business — the workflows, roles and tools — so the work stops living in one person’s head and starts living in the business.
Senior operational leadership without a senior salary. A day or two a week, in your business, owning the machine — for founders who need the capability now but aren’t ready for a full-time hire. Availability is limited to keep the work close and personal.
They didn’t hand me a report and disappear. They stayed until the new process was actually being used. Six months on it’s just how we work now.
I was the bottleneck and I knew it. The audit found four hours a day I was wasting on things that should never have reached me. Worth every penny of the fee.
Warm, sharp, and refreshingly honest about what we didn’t need to spend money on. It felt like having a very calm co-founder for a day a week.
