Sensor Tower uses Ruby for its tech stack, and three team members share why. Software engineers Stefan and Jamal highlight Ruby's gems, metaprogramming, and interpreted nature for rapid prototyping and less code. Data Scientist Daniel notes Ruby's strengths in data cleaning and transformation, which is 80% of his work.
Although Ruby is slower and memory-intensive, Sensor Tower's product doesn't need high performance. The language's readability and DRY philosophy make it a great fit for their analytics platform. For early-career tech professionals, learning about a company's tech stack is crucial, and Ruby at Sensor Tower offers valuable insights.
The open internet presents unique challenges for performance advertising: fragmented identity, closed first-price auctions, and non-stationary supply. Moloco's CARA compound architecture tackles this with six integrated technical domains—Campaign Automation, Supply, Ad Recommendations, Bidding, Creative, and Signals—running on a unified ML infrastructure. Key insights for ad ops: the system continuously learns from every interaction, uses knowledge distillation to serve real-time predictions under 10ms latency, and validates improvements through rigorous live experiments. In 2025, 65 validated model updates reduced CPA by 17% and improved ROAS by 27%. The key takeaway: compound AI architectures that connect prediction, bidding, creative, and data can unlock measurable performance gains beyond walled gardens.
LTV forecasting is challenging due to stale ML models and user heterogeneity. Effective systems combine ML, Bayesian methods, and secondary models to reduce bias and variance for accurate predictions.
Will Frank of Laura Geller describes their Meta ad account as an ecosystem where creative, media, offers, and channels interact. Key insights for ad ops leaders: build a constant creative pipeline to feed AI-driven delivery, test with patience as value optimization took three weeks to show conversions, use AI to automate reporting and pressure-test hypotheses, and focus on system architecture rather than manual targeting. Their multi-touch attribution, MMM, and incrementality testing form a 'suite of truth' to validate performance. The marketer's role is shifting to strategy and AI stewardship.
CTV has become performance-ready for app marketers. Recent acquisitions (Fox/Roku, Walmart/Vibe) signal a shift to self-serve, measurable channels. Marketers can reuse existing UA creative instead of producing TV ads. QR codes drive direct response, but halo effects often matter more. Start with small, additive test budgets and measure assists/incrementality to understand true impact. CTV offers a way to find incremental users and diversify beyond paid social.
TikTok is offering new advertisers up to $6,000 in ad credits through a tiered spend incentive ($100/$500/$1500) that includes 1-to-1 expert support at the top tier.

Alongside the offer, TikTok has rolled out several ad tech innovations—Symphony AI creative suite, Streaming Ads, Agentic Hub, Market Scope, and new MMM data—that provide actionable opportunities for testing and scaling performance. Ad ops teams should review eligibility criteria carefully and consider leveraging these tools to maximize ROI during the promotional window.
