QVentures structures due diligence into three levels. Level 1 is pass or fail filtering by sector, stage, and geography; the firm screens over 1,200 deals yearly against criteria like European tech Series A-C companies with over £1m revenue, or pre-seed UK companies with 12-18 months of runway available. Level 2 diligences the company across team, TAM, product, unit economics, and financials, recommending reference calls plus top-down and bottom-up TAM validation to counter founders overstating their market size. Level 3 diligences the deal, covering instrument and preference stack terms, modeled exit scenarios based on comparable IPO or M&A pricing, and target return benchmarks that vary by stage, roughly 10X over 7 to 10 years for Series A versus 3X for a Series C nearing IPO.

Emerging fund managers or family office investors building their first structured diligence process get a working template from a firm that discloses its own screening criteria rather than generic advice about vetting deals. The tiered structure, cheap pass or fail filtering before expensive deep diligence, is a practical way to manage limited time against high volumes of inbound deal flow, addressing the real constraint smaller funds face when they cannot deeply diligence every opportunity received. The stage specific target return benchmarks, 10X for Series A versus 3X for a pre-IPO Series C, give investors a concrete reference point for judging whether a proposed valuation is consistent with the return profile expected at that stage rather than relying on an ad hoc valuation judgment.
