Product Pieces is a UK-based fractional product agency founded by Alex Feltwell. It runs a free 20-minute Diagnostic to find the missing piece in your product function, then plugs in senior product talent: founder sessions from £150 an hour, nine fixed-scope Set Pieces from £3,500 and ongoing Pieces from £2,000 a month, across CPO, PM, PO, Quality, Coaching and UX in-house, plus partner-delivered Engineering, Brand, Research, Data and GTM.
What Product Pieces is.
Every business is a product, and a complete in-house product function is rarely affordable at every stage. Product Pieces makes that function pluggable: twelve named Pieces — strategy, delivery, quality, design, data, growth, build — that slot in one at a time, for as long as the moment needs. The same senior judgment the funded few can buy, priced the way modern teams buy software.
How it works.
The method is four verbs: Diagnose · Pick · Plug in · Solve. It starts with a free 20-minute Diagnostic that reads your function and names the gap. Then you pick a founder session (£150 an hour), a fixed-scope Set Piece (from £3,500) or an ongoing Piece (from £2,000 a month), a senior operator plugs in within days, delivers, and leaves the team stronger. Coaching is the exit ramp on every engagement.
Who it's for.
Three audiences, one method. Startups pre-product to MVP who need a senior call on the bet without a full-time hire. Ambitious SMEs (established, revenue-funded businesses going further with product) who want to prove what's worth building before committing six figures. And enterprises needing interim cover, specialist depth in regulated platforms, or coaching for the next generation of PMs.
The partners.
Six Pieces are delivered by Product Pieces' in-house bench; six through named partners: engineering through Atomise (a 37-person UK studio, #1 on the Clutch 100 in 2025, with a 4.9/5 delivery rating), brand through CGL Agency, and Research, Data, GTM and Fundraising through a vetted specialist network. Every operator clears the same bar as Toptal's Top 3%, and Product Pieces stays the one accountable owner across all of it.
The founder.
Product Pieces was founded by Alex Feltwell — twenty years building product in regulated platforms and consumer marketplaces, including the £10m Fidelity programme at Bravura (1m+ accounts migrated, the UK's largest wealth migration). Toptal Top 3%. He also founded Atomise, named the #1 UK company on the Clutch 100 in 2025, which is why the engineering Piece carries a track record across SS&C Hubwise, Pepperstone, Fidelity International and TIARA FinTech.
The books.
The thinking behind Product Pieces is also on paper. Alex has written four plain-English field guides for product people — Product Pieces (product management) and its companion Product Pieces: AI Solutions (building with AI), plus Where Your Product Lives (surface strategy) and Cold Start by Design (network effects). Same belief as the agency: get the basics sharp, name exactly how each idea goes wrong, and most of the clever stuff takes care of itself. See all four books.
What working together looks like.
Every engagement starts at the bottom of the ladder and rises by commitment rather than by upsell. The Diagnostic is twenty minutes and free. A founder session is an hour at £150, with nothing recurring unless you want it. A Set Piece is fixed scope at a fixed price named upfront, from £3,500 to £18,000, which maps cleanly to a purchase order with no open-ended scoping and no surprise invoices. Ongoing Pieces run monthly from £2,000 with a three-month minimum and no retainer lock-in beyond it.
Three things hold across all of them. The person in the room is the person doing the work, with no graduates learning on your time and no junior hand-off after the pitch. Product Pieces stays the one accountable owner, including across partner-delivered Engineering, Brand, Research, Data and GTM, so there is one throat to choke rather than five suppliers and a co-ordination problem. And where cash is tight but the upside is real, qualifying CPO, PM and Coaching engagements are equity-friendly: up to forty per cent of fees taken as equity at your last priced round. The full ladder is published, including what each rung costs and what it does not cover.
Where it works.
Delivery is UK-led, with a wholly-owned India subsidiary that is a legal entity rather than an offshore office. Most work is remote with time on site where it earns its keep, and the practice regularly serves clients in the UK, the UAE and Saudi Arabia. Deep ground in regulated wealth and fintech through Bravura, SS&C Hubwise, Pepperstone and Fidelity International, so governance, procurement and risk reviews are familiar rather than a first encounter. References are available under NDA.
What Product Pieces will not do.
It will not take an engagement it does not think you need, which is the whole point of a diagnostic that can end in nothing, keep your money. It will not sell you a build in order to sell you a build, because nobody here is paid by the line of code. It will not put a junior in the seat and bill you for seniority. And it will not tell you what you want to hear: the most valuable hour most founders buy here is the one where somebody with nothing to gain from the answer tells them the plan is wrong.
