March Recap: The Gap Between Analysis and Communication - Issue 309
Your monthly recap of the latest trends, market shifts, and updates in data science and analytics.
Welcome to the Data Analysis Journal - a weekly newsletter on data science and analytics.
If you missed March posts, here’s the roundup:
2026 Benchmarks: More Apps, Less Quality - What RevenueCat and Adapty’s 2026 reports say about acquisition, conversion, retention, and where subscription apps are heading.
Before You Build an Analytics Agent - Getting started with agentic analytics: how to set up business context, benchmarks, and structured workflows
What AI Terms Mean for Analytics - A glossary of key AI, BI, and analytics terms shaping data workflows and decision-making.
March moved fast and felt overwhelming. We had the Gartner Data & Analytics Summit, along with a wave of new reports, launches, and product updates. April looks just as busy. Here are the key updates across data science and analytics: new case studies, analyses, and developments shaping where the field is headed.
But first, quick announcements:
Meet me at Apps in Motion in New York on April 8
Next week, I’ll be speaking at Apps in Motion on April 8 at NASDAQ in New York about driving mobile growth with AI. I’ll be joining FunnelFox, Adapty, and Paddle for a one-day conference focused on scaling subscription apps - from paid UA and web-to-app funnels to paywalls, payment infrastructure, and retention. Come say hi!
Stay tuned for a new SaaS analysis
I’m partnering with ChartMogul to test common SaaS and subscription app assumptions - to prove, validate, or reject them with data. A few weeks ago, we published More Plans, Faster Growth?, which showed a strong link between the number of plans a company offers and its growth and expansion revenue. Companies with more diverse plan catalogs tend to grow significantly faster in both net new customers and revenue.
The next report is even more exciting, and it’s coming soon!
🔊 Advocating for analytics
I want to share a report published by SignalVerified, a hiring platform, that argues traditional hiring signals, like résumés, interviews, and credentials, do not work especially well today, particularly for analytical roles.
What stood out to me is how closely the report matches what I have seen myself. There is often a gap between technical depth and communication. Analysts who do strong analysis sometimes struggle to present it clearly and make it easy to follow. On the other hand, analysts who write polished executive summaries and tell a strong story sometimes end up with weak reasoning, flawed methodology, and incorrect conclusions. Finding people who can do both well is rare, so I was glad to see a report that puts data and psychology behind the same pattern.
The team ran a pilot case study with the UC San Diego Data Science group, and I found the results both fascinating and very reflective of the current strengths and weaknesses in the data and analytics talent pool. Here are the key findings:
Polished output did not mean better reasoning. Some of the best-looking submissions had weak problem framing and conclusions that did not match the business decision.
Problem framing was the biggest differentiator. The strongest participants clearly defined the question they were answering and why it mattered.
Good analysis required restraint. Stronger submissions focused on what mattered most instead of analyzing everything available.
Technical depth alone was not enough. Even strong analysis fell short when it was not tied to a clear, useful recommendation.
Only a subset met the full bar. The strongest submissions combined decision framing, analytical rigor, and executive-level communication.
The team also shared the process they used to reveal capabilities that traditional hiring signals often miss. You can read more about it here - The Case for Verified Performance Evidence.
To me, this report proves why critical thinking has to come first when hiring analysts. It takes time and experience to build, and this is not something people quickly pick up overnight - Mastering Critical Thinking: How to Improve Your Analytical Skills.
🔥 March highlights
Metabase is stepping into AI with its context layer, Data Studio, which lets teams build and manage data models, define metrics, and organize metadata so analytics “stays understandable and reliable.”
Big news for Mixpanel users: the team launched Mixpanel MCP a few weeks ago. It’s now in public beta and lets you connect Claude or Cursor to Mixpanel to generate reports, search for events and properties, or compare insights with other tools in your stack.
Mixpanel also made its Metrics Trees AI-powered - Meet AI Metric Trees: Instant, structured growth frameworks. “Describe your business, product, or growth focus in plain language, and Mixpanel will generate a structured first draft of a Metric Tree informed by industry best practices.” I haven’t tried it yet, but if you have, curious to hear what you think.
Informatica from Salesforce + Microsoft announced a major expansion of their partnership that enables Azure customers to instantly connect 300+ data sources to Microsoft Fabric and create a governed, AI-ready foundation. They are also launching an Azure-based pod in Switzerland to help European enterprises meet strict data regulations requirements.
Congratulations to Preset for raising 7.27M Series C round led by a16z. I like Preset and share team values for open analytics and BI, and I’m curious to see how the company continues to grow.
