First-order effects

• Moloco gets $150M to scale its ML-driven mobile campaign engine, entering the market with unicorn-scale capital while competitors like ActiveCampaign — also Tiger-backed — automate adjacent channels like email and CRM.
• Tiger Global adds another marketing-tech position to a 2021 fund that relationships describe as aggressively seeding billion-dollar startups during the COVID-era funding surge.

Second-order effects

• Mobile advertisers gain a better-funded alternative to incumbents, pressuring rivals on performance pricing as ML-optimized campaigns compete directly for the same app-install budgets.
• The round positions Moloco to become an acquirer of influence rather than just a target: by 2026 it holds a minority stake in AppsFlyer's $1B Series E alongside Google, Meta, and Unity — converting raised capital into cap-table power over the attribution layer it depends on.

Third-order effects

• If the pattern holds, late-cycle mega-rounds don't just mint unicorns — they create strategic investors who consolidate the measurement and attribution stack around a few ad-platform players, with independent martech vendors increasingly owned or influenced by their own customers and competitors.
• Tiger Global's volume strategy across ActiveCampaign, Moloco, OctoML, and beyond illustrates how concentrated lead-investor capital can shape which categories (marketing automation, ML infrastructure) get funded to scale in a single cycle.
