Purpose: This article explains why early-stage ventures frequently display intense activity yet fail to achieve commercialization in institutionally complex environments. It argues that the problem is not simply resource scarcity or weak infrastructure, but whether product, market, and institutional validation become aligned over time. Design/methodology/approach: The study adopts a longitudinal, abductive, multi-venture design based on 15 early-stage technology ventures operating across African markets over a 12-month period. Drawing on milestone plans, quarterly progress reports, budget allocation records, and advisory or engagement records, the analysis traces how validation processes unfold, interact, and diverge across venture trajectories. Findings: Three recurrent outcome regimes emerge: commercialization, artificial progression, and stagnation. Commercialization occurs when product, market, and institutional validation advance in a coordinated and mutually reinforcing sequence. Artificial progression arises when ventures generate credible activity and visible advancement in one or more domains, yet fail to convert this momentum into commercialization because validation remains cross-domain misaligned. Stagnation occurs when ventures do not accumulate sufficient validation to build cumulative legitimacy. Across cases, sequencing capability, the ability to order validation efforts so that gains in one domain unlock gains in others, appears to be a critical differentiator. Originality/value: The article contributes by reframing venture progress as an alignment-dependent accomplishment rather than an activity count, theorizing artificial progression as a distinct structural condition, and introducing Institutionally Mediated Market Formation (IMMF) as a process-based explanation of commercialization under institutional complexity. The study extends entrepreneurship, legitimacy, and ecosystem research by showing that visible activity is an unreliable proxy for progress unless it becomes commercially convertible through cross-domain validation alignment.
