Key Discussion Points & Insights
1. SCOTUS Strikes Down Broad Presidential Tariff Powers
[00:16–05:33]
-
Background:
The Supreme Court ruled (6–3) that President Trump’s use of the International Emergency Economic Powers Act (IEEPA) to impose sweeping tariffs is not legal.- Small businesses, like Learning Resources Inc. (Illinois), had challenged the legality, citing economic harm to the 97% of U.S. importers who are small businesses.
-
Legal Reasoning:
- IEEPA was intended for addressing national emergencies, not as a tool for broad tariff policy.
- Constitutionally, Congress—not the President—holds the power to lay and collect tariffs and duties.
- “Such significant economic policy decisions require explicit congressional authorization.” (Anne Barry, [01:42])
-
Immediate Aftermath:
- President Trump quickly pivoted, announcing a global 15% tariff under Section 122 of the Trade Act of 1974. This has never before been invoked and may face legal challenges.
- The market’s reaction was muted—volatility, but largely anticipated.
- Uncertainty remains: especially around whether $130 billion in now-illegal tariffs should be refunded to businesses. The Supreme Court did not rule on refunds, opening the door for more litigation.
Notable Quote:
“We’re back to uncertainty on the tariffs front when it comes to what a long-term policy may look like. But what does seem certain is that the Trump administration is not going to let this go and will keep pushing to keep its tariffs in place.” — Anne Barry ([04:28])
2. Market Movers: Earnings Snapshots
[05:33–07:29]
-
AMC Entertainment ([05:55])

3. The Software Sell-off: Inside the Storm
[07:29–27:38]
Market Overview
- Software stocks have been battered by AI-related fears, with big names like Salesforce, Adobe, ServiceNow, AppLovin, Datadog, and Workday undergoing sharp declines. IBM fell 11% after Anthropic’s Claude code product threatened its core data business; cybersecurity stocks like CrowdStrike also suffered.
Key Points:
- The perceived existential risk of generative AI is unnerving investors.
- Even companies posting strong financials are seeing their stocks slide.
Amanda Whalen Interview: Klaviyo’s Response
About Klaviyo & Current Business Climate ([09:21])
- Klaviyo powers marketing automation for nearly 200,000 consumer businesses.
- Strong Q4:
- 30% revenue growth,
- Expanding margins,
- Higher revenues per message due to more targeted, AI-driven campaigns.
Quote:
“Business is incredibly strong... It was an incredibly strong quarter for Klaviyo in Q4 with 30% revenue growth.” — Amanda Whalen ([09:59])
Shifts in Customer Engagement
- Clients are shifting from mass-email “blasting” to highly-targeted outreach.
- Focus is on engaging loyal, high-value customers, especially during key retail periods.
- Targeted communication yields better results:
“During Q4, they sent messages to a smaller but much more highly engaged group of customers... which triggered higher revenue per message.” — Amanda Whalen ([10:34])
Differentiation in a Crowded Market ([13:12])
- Klaviyo’s advantage: Data-driven intelligence loop, ingesting 3.7 billion data points per day.
- Claims more precise engagement than main competitors (Mailchimp, Attentive), even as channels like SMS and WhatsApp become noisier.
- The focus: Personalized, relevant communication that builds strong, loyal relationships.
ChatGPT, LLMs, and Customer Relationship Disintermediation ([14:58–16:50])
- Partnering with LLMs (e.g., ChatGPT) is viewed as a positive, not a threat.
- LLM-based purchases give brands new discovery pathways but still allow the brand to "own" the relationship post-first purchase.
Quote:
“So the way that we see it for our customers is that it levels the playing field... with LLM they now have more of an opportunity to be discovered, to be found, to get that initial first sale and then to turn that into an ongoing loyal repeat customer relationship.” — Amanda Whalen ([16:30])
Shopify Relationship & Concentration Risk ([18:34–22:53])
- 78% of ARR comes from customers also using Shopify.
- Shopify is a major partner and investor.
- Klaviyo is expanding into other ecosystems (Salesforce, WooCommerce, PrestaShop, Shopware), but management views concentration as a strength, not a primary risk.
- As Klaviyo moves further upmarket and internationally, more revenue comes from non-Shopify partners.
SMBs, AI Threat, and Investor Messaging ([24:39–27:28])
- Some analysts worry that small and mid-sized customers might defect to free/cheap AI tools as generative LLMs improve, increasing churn risk.
- Amanda Whalen’s pitch:
- AI is an accelerant, not existential threat, for Klaviyo.
- Quality, ease-of-use, and automation allow time-starved SMBs to achieve better open and revenue rates (e.g., one customer saw 50% higher open rates and 40% higher average revenue per campaign using Klaviyo’s agent).
- Larger customers want a unified customer journey and trust Klaviyo’s data integration.
Quote:
“The key message for our teams internally and for investors is that AI is an accelerant to our business... For Klaviyo, AI is accelerating our business and we are very uniquely positioned here to win.” — Amanda Whalen ([25:44–26:45])

-
On LLMs as an opportunity:
