Stephen Ju's questions to Ibotta (IBTA) leadership

Question · Q4 2025

Stephen Ju asked about the trend of third-party redemptions per redeemer, noting its sequential bottoming but still being below last year's levels. He questioned whether a normalization of CPG ad budgets would drive recovery and what client conversations Ibotta is having to secure more attractive and compelling offers, balancing quality and quantity.

Answer

Bryan Leach, Founder and CEO, explained that offer supply (more, better quality, longer-lasting offers) directly impacts redemptions per redeemer. He stated that Ibotta's improved core capabilities, favorable pricing, third-party measurement, and LiveLift are designed to increase offer supply and client credibility. Mr. Leach emphasized Ibotta's primary focus on total redemptions and total redeemers, noting a nearly 25% year-over-year increase in redeemers. Matt Puckett, CFO, added that improved execution, core product strength, and LiveLift expansion are collectively enhancing offer supply and driving positive business trends, giving confidence for revenue growth later in 2026.

Question · Q4 2025

Answer

Jeffrey Stibel, Chairman and Chief Executive Officer of LegalZoom.com, stated that the success in upselling Formation Nation customers is similar to LegalZoom's own base, though potentially slower than desired, as Formation Nation serves as a value-priced service offering.

Question · Q1 2025

Stephen Ju of UBS asked about the potential to unlock incremental customer lifetime value (LTV) from Formation Nation's transactional base and whether that could lead to more aggressive customer acquisition spending.

Answer

CEO Jeff Stibel explained that the immediate win is bifurcating customer types, sending lower-intent users who need more handholding to Formation Nation's effective onboarding process. He noted that while there is a significant opportunity to introduce subscriptions to the Formation Nation base, they are careful not to break a model that already works well. COO & CFO Noel Watson added that they have already started to increase marketing spend for Formation Nation and that realizing LTV opportunities would certainly expand what they can do on the acquisition front.

Stephen Ju's questions to Airbnb (ABNB) leadership

Question · Q4 2025

Stephen Ju's questions to AppLovin (APP) leadership

Question · Q4 2025

Stephen Ju asked whether AppLovin is demand-constrained versus supply-constrained, the potential for more supply, and the company's strategy for targeting advertisers of a certain size.

Answer

He confirmed a focus on performance-based advertisers (D2C, Shopify merchants) rather than brand dollars or large agencies, aiming to help smaller businesses scale rapidly, mirroring their success with indie game developers.

Question · Q4 2025

Stephen Ju asked whether AppLovin is demand-constrained versus supply-constrained, how much more supply (new/existing publishers) can be added, and about targeting advertisers of a certain size (smaller first, then larger/upper funnel).

Answer

Adam Foroughi stated they are far from needing new publishers, emphasizing that the market is not zero-sum and there's significant room to monetize the 1 billion+ daily users, expecting conversion rates to rise from ~1% to 5% with more diverse advertisers. He clarified they target anything not 'brand dollars' (i.e., performance-based, transactional, or lead-based), preferring smaller D2C/Shopify merchants who see direct correlation to revenue, as this creates more value and dependency on their platform.

Question · Q1 2025

Stephen Ju requested color on the factors causing the year-over-year decline in international revenue. He also sought commentary on the monthly active pro metric, noting that it appears to be nearing a trough as acquisition and churn rates converge.

Answer

CEO Jeffrey Kip explained the international revenue decline was driven by a strategic shift in the Canadian business to a higher-ROI, lower-revenue online acquisition model, and regulatory impacts in Europe (Digital Services Act) that created temporary conversion headwinds. Regarding monthly active pros, Kip stated that while the gross number will continue to decline into 2026 due to winding down unprofitable legacy acquisition, the capacity per pro is increasing. He anticipates the raw number of pros will begin growing by 2027, driven by the rollout of online pro enrollment in the U.S.

Answer

CEO David Risher asserted that Lyft's customer-obsessed innovation strategy remains unchanged, calling it an 'imperative' in tech.
