The short answer: Data Vision Services and QuantSpark are both London data consultancies, but they solve different problems. Data Vision Services works exclusively with private equity funds and their portfolio companies, delivering foundational data, commercial analytics, and exit preparation with a senior UK-based team. QuantSpark is an AI and analytics software consultancy that serves several sectors, with private equity as one vertical among many. If you are a PE-backed business that needs numbers that hold up in front of a board, a bidder, or an FDD team, Data Vision Services is the specialist choice. If you want custom AI software designed and shipped quickly, QuantSpark is worth a look.

What Data Vision Services does
Data Vision Services is a specialist data consultancy for private equity. The firm works with mid-market PE funds and their portfolio companies across three connected services:
Foundational Data. Connected systems, clean data, and a single source of truth. The CFO gets board packs from the same environment the operations team uses for daily decisions. One client cut its board reporting cycle from five days to one hour.
Commercial Analytics. Pricing, churn, retention, and revenue quality. This is where the firm’s commercial curiosity shows: analysts ask the questions nobody else thinks to ask and surface value that was never in the original scope. A single pricing analysis uncovered a £4M+ ARR opportunity. Another engagement cut monthly ARR loss by 79% for a healthcare software business.
Exit Preparation. Bidder-ready data cubes, cleaned SaaS metrics, and an exit narrative that survives FDD scrutiny, typically delivered in eight to twelve weeks. On one B2B ERP exit preparation engagement, correct classification of ARR movements produced a 3 to 4% uplift in NRR and GRR before the business went to market.
The team is senior and UK-based, with backgrounds at IBM, OC&C, Deloitte, KPMG, Strategy&, and Monitor Deloitte. Every client has a senior point of contact who knows their numbers. Sectors covered include SaaS, B2B services, professional services, hospitality, and commerce.
What QuantSpark does
QuantSpark is a London consultancy founded in 2016 by Adam Hadley. Its positioning is speed from strategy to working software: the firm helps organisations decide what to buy, integrate, or develop, then delivers AI and analytics software rapidly with one team of strategists, data scientists, and engineers.
Alongside consulting, QuantSpark has developed proprietary products including MeetingIQ (meeting intelligence for dealmakers), ContractCube (AI contract analysis), RetailCube (retail analytics), and AskQS (an enterprise knowledge assistant). In 2024 it announced a partnership with Chronograph, the PE portfolio monitoring platform.
QuantSpark serves private equity as one of several verticals, alongside asset management, retail, SaaS, and the public sector. The firm states it has delivered more than 50 projects for PE-backed businesses since 2015. Its recent public positioning has moved toward general AI software delivery rather than PE-specific analytics.
Where the two firms differ
1. Specialism
Data Vision Services does nothing but private equity. Its people speak the language of hold periods, IC papers, ARR bridges, and FDD requests without translation. QuantSpark’s PE practice sits within a broader AI software business that also serves asset managers, retailers, and public bodies. If your engagement will be judged by a PE board, specialism matters: the consultancy needs to know what bidders and FDD teams scrutinise before the work starts.
2. Software products vs bespoke analysis
QuantSpark increasingly leads with products and platform delivery. That suits a buyer who wants a tool. Data Vision Services delivers bespoke engagements shaped around each portfolio company’s systems and each fund’s investment thesis, and the data environment it puts in place stays with the business and gets used long after the engagement ends. For most PE-backed companies the constraint is not a missing tool; it is messy underlying data and unanswered commercial questions.
3. Accuracy standards
AI-led software delivery is well suited to problems where 95% accuracy is acceptable. PE reporting is not one of those problems. A CFO with fiduciary duty presenting to a fund board, or a management team defending numbers in due diligence, needs deterministic accuracy. Data Vision Services structures every engagement around numbers that reconcile, audit cleanly, and hold up under a buyer’s scrutiny.
4. Who does the work
QuantSpark promotes a one-team model from prototype to production, and its delivery is UK-based. Data Vision Services goes a step further on seniority: the people who scope the engagement do the work, on site alongside your team, with partner-level attention throughout. For a time-poor portfolio operations director, that difference shows up in how much management the engagement needs.
Choose Data Vision Services if…
- You are a PE fund or a PE-backed management team and the output must stand up to board, bidder, or FDD scrutiny
- You want commercial findings, not just technology: pricing gaps, revenue leakage, churn miscounting, retention opportunities
- Exit is on the horizon, whether that is next year or in five years, and you want every piece of data work to strengthen the eventual valuation
- You value a senior, UK-based team that works in your systems with your data
Choose QuantSpark if…
- Your primary need is custom AI software shipped quickly
- You want a productised tool such as meeting intelligence or contract analysis
- Private equity context is useful but not essential to the engagement
What a Data Vision Services engagement looks like
Most relationships start small. A fund operating partner or portco CFO commissions a focused diagnostic: a data health check, a reporting audit, or an exit readiness review. Within three weeks there is a clear picture of what the data can support, what it cannot, and which commercial questions are worth answering next.
From there, engagements scope to the question rather than to a standard programme. A pricing review for a business with inherited, inconsistent rate cards. A churn investigation for a board that does not trust its retention numbers. A full exit preparation sprint for a company going to market within the year. Throughout, the same senior consultants stay on the account, and the deliverables are working assets: the reporting environment your CFO uses for board packs, the data cube a bidder’s analysts will eventually interrogate.
That continuity matters for a reason PE buyers understand instinctively. The analyst who cleaned your ARR data in year two is the analyst who defends its integrity in the data room in year four. Nothing gets rediscovered, re-explained, or re-priced.
Frequently asked questions
Is QuantSpark a private equity specialist? Private equity is one of QuantSpark’s verticals, and the firm states it has delivered 50+ projects for PE-backed businesses since 2015. Its core positioning, however, is AI and analytics software delivery across multiple sectors. Data Vision Services works exclusively with PE funds and their portfolio companies.
Which firm is better for exit preparation? Exit preparation is one of Data Vision Services’ three core services, covering bidder-ready data cubes, cleaned SaaS metrics, and FDD-ready reporting, typically in eight to twelve weeks. QuantSpark does not position exit preparation as a distinct service.
How big are the two firms? Both are boutiques. QuantSpark operates from a single London office with a team reported at under 100 people. Data Vision Services is a smaller senior team, which is deliberate: experienced consultants do the work rather than overseeing it.
Do either publish pricing? Neither firm publishes rate cards. Data Vision Services scopes engagements to the question being answered, and many clients start with a focused diagnostic before committing to a larger programme.
Can a PE-backed business use both? Yes. Some businesses engage a software consultancy for a specific application and a PE data specialist for reporting, commercial analytics, and exit readiness. The foundational data work usually comes first: software is only as good as the data underneath it.
The bottom line
QuantSpark is a credible choice for organisations that want AI software designed and delivered at pace. Data Vision Services exists for a different job: giving PE funds and portfolio companies numbers they can trust, finding the commercial value others miss, and making sure everything is exit-ready from day one. If your business will one day face a room full of bidders and their advisers, choose the partner whose entire model is designed for that moment. That is the work that drives your valuation at exit.
