Accelerating data-driven decision-making with embedded analytics consultants

An ESG-focused investment manager reduced reporting errors by more than 90 per cent, moved from annual to monthly reporting, and cut the manual effort behind that reporting from more than 40 hours a month to around half a day, all without building a costly in-house analytics team from scratch. The firm also reports freeing roughly a fifth of its analysts' time for higher-value strategic work and attributes a 5 per cent uplift in investment performance to the improved predictive analytics that followed.

The problem QuantSpark was brought in to solve is a familiar one for investment managers of this size. Timely, data-driven insight was becoming a competitive necessity, but building that capability internally carried real costs and real delay. Specialist analytics and data-science hires are expensive and hard to recruit in a tight market, and even once hired, they take time to onboard and reach full productivity. On top of that, the firm's existing teams had limited exposure to modern analytics tooling and methods, and capacity struggled to keep pace as data demands grew.

That capability gap showed up most visibly in reporting. Portfolio and performance reporting was still a manual, once-a-year exercise, assembled by hand and prone to the kind of transcription and consolidation errors that manual processes invite. There was no clear data strategy to guide investment in better tooling, and the resulting skill gap was holding back innovation across the research and portfolio functions.

QuantSpark's response was to embed strategy and analytics consultants directly inside the client's research and portfolio teams, working as an extension of those teams rather than as external advisors on the sidelines, with the wider consultancy's engineering and data-science bench available behind them for anything that needed deeper technical lifting. From that embedded position, the team worked through several parallel strands: automating portfolio reporting by building ETL pipelines and dashboards to replace manual compilation; setting an 18-month data roadmap that prioritised both automation and opportunities to generate alpha; delivering rapid, bespoke analysis on demand as research questions arose; and running a citizen-developer programme to teach internal staff SQL and AI skills, so the client's own people, not just the consultants, came out of the engagement more capable.

That combination follows a consistent workflow: diagnose where reporting and data-strategy gaps were costing the business time and accuracy; embed consultants inside the existing teams rather than deliver from outside; automate the reporting mechanics that had been eating analyst hours; advise on both the day-to-day ad hoc questions and the longer 18-month roadmap; and upskill internal staff so the gains outlast the engagement itself. The systems put in place were deliberately categorical rather than exotic: automated ETL pipelines feeding into reporting dashboards, and SQL and AI training delivered through the citizen-developer strand, sitting on top of whatever data infrastructure the client already had.

The value case rests on figures the client itself measured and reported, not on a modelled or illustrative number. Monthly reporting effort fell from more than 40 hours to around half a day, a reduction that also let the firm move from annual to monthly reporting cadence, itself a meaningfully more responsive rhythm for an investment business. Reporting errors fell by more than 90 per cent, the headline figure. Ad hoc analytics capacity freed by automation returned roughly 20 per cent of analysts' time to strategic work rather than manual reporting. The firm also reports a 5 per cent uplift in investment performance that it attributes to improved predictive analytics, though this is the client's own attribution rather than an independently isolated causal measurement. Taken together, the engagement avoided the recruitment costs and time-to-value lag of building an equivalent capability in-house, while the citizen-developer programme means the client's own teams, not just QuantSpark's consultants, retain the skills going forward.

The return on this kind of engagement is best understood as a combination of three levers: the time reclaimed from manual reporting, redirected to higher-value work rather than banked as a headcount saving; the fixed cost avoided by not recruiting, onboarding and retaining a permanent specialist team; and the compounding value of internal capability that persists after the consultants roll off. None of these levers has been converted into a single pound figure in the source material, and this write-up does not manufacture one.
