John S. Kim shared thisToday, I say farewell to a company I called “home” for the past 9 years. I feel privileged to have been part of building what was called CSN Stores when I joined into the Wayfair that it is today. From building Pricing & Profitability to launching the Competitive Intelligence capability to countless other critical initiatives, we worked tirelessly to make Wayfair a “household” name. Beyond this though, I am most proud of the team. The combination of their raw intellect and internal drive layered with their ability to innovate made for the most potent team I’ve worked with. Thank you to everyone who made this amazing ride so fun and fulfilling - I’ll sincerely miss all of you. As for my next step, I am excited to take an extended break to catch up on life, but first, any tips on what to do with all my business cards? #sabbatical #willmissthediscounts

John S. Kim reacted on thisJohn S. Kim reacted on thisI'm happy to share that I will be joining MassChallenge as Chief Operating Officer and could not be more excited! MassChallenge backs founders early, removing barriers, and creating real pathways for companies to grow. At a time when AI and emerging technologies are reshaping how companies are built and how they operate, that kind of support system matters more than ever! I'm a constant evaluator of my own career, often reflecting on how I can continue to grow and add more value to the businesses I support and to my colleagues. One thing I've learned is that I thrive and do my best work when I'm engaged with builders. There's a certain energy in environments where people are constantly creating, learning, iterating, and figuring things out. My time at Formlabs reinforced that in a real way. Earlier in my career at Wayfair, I saw a different version of that same mindset at scale, which I sum up as: how strong operators and teams can turn ideas into enduring companies. That combination of early building and scaling has shaped how I think about impact and where I can contribute most. And has led me to this next journey at MassChallenge. If you’re building something (or thinking about it), I’d love to connect! Or if you're thinking about your own career and making a bold move, I'm always available as a sounding board and a champion of change!

John S. Kim liked thisJohn S. Kim liked this"Dad, I ran out of credits." My son called me last night. He's been using Claude Code to build things. Writing software. Running agents in parallel. He figured out git worktrees on his own and texted me about it — awesome. I had the privilege of saying: "Cool. Let me get you a Max plan so you're unblocked." Many families can't. Over the last few years I've toured maybe thirty campuses. The script is always the same. They walk you to the library: "If we don't have the book, we ship it from another library in the network." Then the maker space: "Students can 3D print anything they want." I'm standing there thinking — you are missing the point entirely. Not one school mentioned anything about AI. – ZERO. Knowledge in 2026 isn't hardcover books, no matter how romantic they are. And making isn't 3D printing. The knowledge that matters is access to intelligence. To tokens. The making that matters is what happens when a student opens Claude Code and ships something in an afternoon. I pay an obscene amount of tuition (don't even ask). And I still pull out my credit card to buy my kids the tools that actually matter. Something is wrong. Three simultaneous failures: * Universities should fund AI access the way they fund lab equipment. * AI companies haven't built the institutional access models education demands. * And public policy hasn't caught up to the reality that AI access is becoming as fundamental as Wi-Fi. This stopped being abstract when I thought about hiring. Claude Code has a feature that shows your usage insights (/insights). I was excited about it as a hiring signal. If a candidate showed me their stats, that would tell me a lot about whether they get this moment. Then I caught myself. If I make AI fluency a hiring requirement, I'm penalizing every talented person whose family couldn't afford the tools. That's a wealth filter wearing the clothes of a skills assessment. We need a Carnegie moment for AI. Andrew Carnegie recognized something similar 150 years ago. Peoples potential was unlocked when given access to knowledge. Back then it was books, so he then built 2,500 libraries. Universities already negotiate consortium licenses for journals and databases. The same model works here. Every enrolled student gets a meaningful monthly token allocation, the way they get library access, lab time and Wi-Fi. Somewhere right now, a student is hitting the same wall my son hit last night. My son got unblocked with a credit card. Another student might not. One kid keeps building. The other stops. That’s the gap we need to close. #AI #EdTech #HigherEducation #DigitalDivide #FutureOfLearning

John S. Kim liked thisJohn S. Kim liked thisI don't usually post on LinkedIn, and I'm definitely not one to brag. But I've been quietly building stuff at work that I think is worth sharing — not because I'm special, but because it shows what's becoming possible for non-engineers willing to get their hands dirty. I'm the CFO of a marketplace startup. My job is spreadsheets, compliance, cash management, and making sure the lights stay on. I'm not a developer. But over the past few weeks, I've been using Claude in ways I didn't think were possible just a few months ago. It started with Chat — using Claude as a thought partner for things like reviewing legal redlines, drafting employee handbook language across 18 state supplements, and pressure-testing arbitration clauses against precedent. Not "hey write me an email" stuff. Real work product that goes to outside counsel. Then I discovered Claude Code and started building actual internal tools — a notification performance dashboard, a cash management rebalancing app, a weekly forecast tracker. I wrote the specs, Claude wrote the code. A CFO shipping React apps is... not something I expected to put on my résumé. Connectors changed the game again. Claude plugged into my Google Drive, Gmail, etc — so instead of context-switching across ten tabs, I can pull what I need into one conversation. It knows where my documents live. Cowork took it further. Instead of me babysitting every step, I can hand Claude a file and a set of instructions and let it work autonomously — processing ad spend reports, rolling over monthly close folders, generating financial deep-dive decks. Tasks that used to eat hours now take minutes. And Skills tied it all together. I'm building custom reusable workflows — my own little library of automations tailored to exactly how our company operates. Monthly scorecards, close report downloads, ad spend summaries — all standardized, all repeatable, all built by someone whose last programming class was html in 1996. None of this required an engineering team. None of it required a budget approval. It just required curiosity and a willingness to iterate. I'm not posting this to say "look at me." I'm posting it because if a finance person at a startup can do this, there are a lot of people sitting on way more potential than they realize.

John S. Kim liked thisJohn S. Kim liked thisShopperoo started as a price comparison tool for shoppers. 20,000+ daily users, 10+ retailers, real-time. The same data that helps a consumer find the best price is exactly what a retailer or brand needs to set one. We built that side too. A large sporting goods retailer asked Shopperoo to match their SKUs against Amazon’s. The reason match rates are typically so low: “Nike Pegasus 41 Men’s Road Running Shoe” on one platform is “Nike Men’s Air Zoom Pegasus” on another. Same shoe. String matching doesn’t find that. Shopperoo does. Their existing tool matched 7%. Across footwear, apparel, equipment, accessories. Shopperoo matched 39%. Same catalog. 6x improvement. At 7%, you’re pricing against a fraction of your real competitive set. At 39%, you’re actually playing the game. See how much of your competitive set you’re actually seeing. Start with a free pilot — link in comments.

Luke ran his first full marathon with Team World Vision. He ran his first half marathon at age 10, climbed Mt. Kili at age 11, and today, 26.2 miles – all to support a cause bigger than himself. Grateful to return to San Antonio for a very different reason, and proud to be on the sidelines cheering Luke Chung on. #teamworldvision, #proudmom

John S. Kim liked thisJohn S. Kim liked thisIt has been surreal to be in Davos this week for the World Economic Forum. It is an honor to be invited to share an evangelical Christian perspective on many of the great issues facing our world. I would appreciate your prayers that my presence here would bear fruit. At the start of the week, I had the privilege of leading devotions and prayer at the USA House. We reflected on Daniel 2:20-22: Praise be to the name of God for ever and ever; wisdom and power are his. He changes times and seasons; he deposes kings and raises up others. He gives wisdom to the wise and knowledge to the discerning. He reveals deep and hidden things; he knows what lies in darkness, and light dwells with him. I also had the opportunity to be part of several panels. One focused on the age of artificial intelligence and its rapidly expanding influence on society. Beyond questions of technology are the most fundamental questions of life. What does it mean to be human? How are human relationships being restructured? And where is the sacred in all of this? I'm grateful for the opportunity to offer an evangelical Christian perspective in this conversation. Other panels explored faith and society (with the cofounder of Wikipedia and other interfaith global leaders) and how faith journeys have shaped leadership (alongside leaders such as the Prime Minister of Kosovo and Kelsey Grammer). I’m closing out my time tonight by joining global faith and civic leaders to present the possibility of collective impact based upon sacred values. Thankful for these conversations and for the ways faith continues to speak into the most consequential questions of our time.

It’s easy to go along with the status quo, even when data quality is slipping. In the Data Gurus panel on data quality, Jon Kay of Intuit shares why that approach is no longer sustainable. He emphasizes that researchers need to start by asking vendors the right questions, pushing them to show how they are addressing today’s challenges instead of relying on outdated methods. By bringing these issues to light and holding partners accountable, we can create the incentives necessary for real progress.

Advanced market research analytics is a lot more than just clicking buttons in a software package. It’s about creative problem-solving, strategic business insight and a strong research mindset. A good methodologist: 🎯Knows the right questions to ask to refine and clarify study objectives. 🎯Can draw from a wellspring of experience but is not limited by it, remaining open to new approaches and innovative solutions. 🎯Finds that sweet spot between rigor and pragmatism, creating solutions that address study objectives in the most efficient way possible. 🎯Can defend the study design to all audiences, friendly and hostile, experienced and inexperienced, adapting communication style as needed. 🎯Can discuss methodology in terms that are simple but not patronizing, comprehensive but not pedantic, ensuring clarity for all stakeholders. 🎯Is easy to work with and fosters a collaborative environment. So, the next time you are tempted by the low cost of off-shore resources or “automated insights platforms,” remember that when it comes to advanced analytics, experience consistently outperforms inexperience, and Real Intelligence delivers more meaningful results than Artificial Intelligence every day of the week. Low cost does not always equate to good value. Want to find out what it’s like working with a real methodologist? Drop me a line on LinkedIn or at Shiv@RamanAnalytics.com.

This research has been brewing for a while... It started earlier this year when I started to notice wildly different forecasts for tech spend, tech markets, economic growth, export growth etc. This basically said "we don't have a clue what is around the corner". So if you don't know what's coming, how do you prepare for that future? I did a lot of research, and with some excellent guidance from my Ecosystm colleague Alea Fairchild, we determined the answer is: BACKCASTING You start with the future vision and work your way back to today. This helps sharpen your focus on what matters to get you to that place. It helps you protect your budgets from global leaders who see the wildly different forecasts and feel they need to cut now. Cutting now might not be the answer - but how do you defend that budget? BACKCASTING. Show where you are going, what you need to get there and how cutting will impact your ability to deliver that future outcome. This isn't a new idea. Apple does it. Tesla does it. Governments do it. You should do it - try it at a micro or macro level to secure budgets and achieve your goals in Asia Pacific or your own specific geo, industry or product area. Tell your clients about it to help them lock in budgets for the initiatives that might drive your solution into their business. Check out my blog below and download the full report for more information. And if you need our help in starting or benchmarking your backcasting journey please reach out!

There’s been an explosion of ‘off-the-shelf’ analytics platforms promising capabilities like MMM, attribution/MTA, segmentation, LTV modeling, , and more. I come from the more traditional approach - working closely with statisticians to build custom models from the ground up These new platforms promise speed, accessibility, and scale. The traditional approach offers deeper customization and often more methodological rigor. But now AI is entering the equation - raising a bigger question: Will AI augment analysts… or eventually replace much of this work altogether? We’re planning a bit of a 'bake-off' internally to compare approaches, but it feels like the bigger shift is structural: how analytics actually gets done may be changing. Curious how others are thinking about this: - Are off-the-shelf platforms “good enough” for most companies? - When does a custom statistical model still matter? - And does AI ultimately reshape—or disrupt—both approaches? Feels like we’re at a real inflection point in the analytics industry. Would love your thoughts and experiences here.

We're facing more and more questions about the use of synthetic data in market research. I'd recommend this blog post, which really resonated with me. So much of the conversation is "how closely can this replicate human data?" But there are so many other considerations researchers should be thinking about. https://lnkd.in/eSQfSTPj

Today we launched Dig One and it’s such a big step forward for Dig Insights! Insights teams shouldn’t have to choose between speed and strategy. But too often, fragmented tools and disconnected partners make that trade-off unavoidable. Dig One brings together the capabilities of OneCliq and Upsiide into one ecosystem, designed to support smarter and faster decisions without compromising depth. Proud of the work that went into this launch and excited for what it unlocks for our clients 🧡
