We write Cash & Cache, a tech newsletter dedicated to AI research & implementation exploring the intersection of technology and business.
Before this, we spent our early careers at crossroads of finance and tech — capital markets, high-frequency trading, banking, insurance. High-stakes environments where things break in expensive ways and a few milliseconds of latency is the difference between profit and loss. Different corners of finance and tech, but we ended up obsessed with the same question: where does AI actually do the heavy lifting, and where is it just noise?
We didn’t plan to write a newsletter together. We were both battle-testing AI workflows independently — figuring out what works without constant micromanagement, writing about it, sharing findings openly. What started as separate explorations became a shared conviction: the AI space had a signal-to-noise problem, and nobody was solving it for practitioners.
Cash & Cache exists because of that conviction. A filter, a blueprint, and a strategy — for people who want to get to the root of every matter than speculate.
Today, we’re sharing what comes next.
What We’ve Built (By the Numbers)
Over the past year, we’ve published 45 deep-dive articles across two tracks — the Cash track covering market shifts and underreported AI developments, and the Cache track delivering step-by-step implementation guides you can actually use.
We’ve collaborated with 15 other newsletter creators and practitioners to bring you perspectives we couldn’t offer alone. We’ve grown to 900+ subscribers owing to our content itself and your wonderful support. Our open rate sits at 34%, not bad for a tech newsletter. That number matters to us because it means you’re not just subscribed — you’re reading.
But what’s been most fun to work with: we run Cash & Cache on the same AI workflows we write about. Our content pipeline, distribution, thumbnail generation, social promotion, and editorial process are all systematized with AI tooling — the same kinds of tools and techniques we cover every week. We believe it’s better to not just report on AI implementation but be a working example of it as well.
What We’ve Learned From You
Over dozens of conversations — in comments, in Chat, in DMs — a pattern kept showing up. Readers wanted more depth on the implementation side. Not just “here’s how it works” but “walk me through building it, give me the templates, let me ask you questions when I get stuck.”
We kept hearing variations of: “I trust your analysis.” “I want more of such forensic research.” And, “I want access to the way you build all of this.”
We believe that’s not something a free newsletter can deliver sustainably, especially at the level of depth and consistency our readers expect. Depth takes time and effort. Access takes infrastructure. And the kind of forensic research and hands-on support our readers were asking for — that takes a different model entirely. brings us to the spotlight of today’s announcement.
🚀 Introducing Cash & Cache Premium
The free newsletter tells you what matters and will continue to deliver the same quality of output. The premium tier will show you exactly how to act on it — with deeper research, working templates, and direct access to the tools and people behind the analysis.
Specifically, the premium tier unlocks the following:
Deeper Implementation Guides: The free Cache track gives you the framework. Premium guides go further — full builds from concept to deployed workflow, with the actual prompts, templates, and configurations included. The kind of detail that turns a “that’s interesting” into a working system on your end.
Forensic-Level Research: Our free Cash track covers market shifts and developments. Premium research goes deeper — forensic analysis, side-by-side model benchmarks, original illustrations, and data dissections you won’t find in surface-level reporting. Think less “here’s what happened” and more “here’s exactly what the numbers say, what they don’t say, and what that means for your decisions.”
Exclusive Tools & Resource Library: Templates, prompt libraries, workflow blueprints, and reference materials we’ve built and tested ourselves. These aren’t generic downloads — they’re the same assets we use to run Cash & Cache, packaged so you can adapt them to your own work. For example, premium subscribers get free access to our full-stack BMAD (Breakthrough Method of Agile Development) Orchestrator for vibecoding (normally available on Gumroad).
Subscriber-Only Community Premium members can start chat threads — bring implementation questions, workflow problems, or strategy debates directly to the community. This is where the Cash people meet the Cache people, and we’re intentional about keeping it signal-heavy.
Premium membership: $8/month or $70/year.
However, for the first week, we are offering a Launch Week Discount!
🎉 Launch Week Offer: 40% off the annual plan — $42/year ($3.50/month)
This price is available for one week only, before 12th March, 2026, 10:00 CET.
🏅 Founding Member Offer
We are offering a Founding Member tier of ($150/year) with everything in the Premium tier, plus:
Monthly 1:1 AI Workflow Session Every founding member gets a monthly one-on-one session with Raghav or Ashwin. Bring your current AI workflow, a specific implementation challenge, or a strategy question — we’ll dig into your actual use case and identify the highest-leverage improvements. This is practical, personalized support, not a sales call.
🎯 What Stays Free
Let us be direct about this: nothing changes for free subscribers.
We publish up to two articles per week — one free, one paid. Free subscribers continue getting the same quality and depth you signed up for. All our readers get access to our “Cash in” threads opened twice a week for sharing and engaging with other creators. If you never upgrade, your experience doesn’t degrade. That’s a commitment, not a caveat.
The premium tier adds a layer on top. It doesn’t take anything away from what’s already here. If Cash & Cache has helped you think more clearly about AI implementation — if even one article saved you time, changed your approach, or gave you something concrete to work with — the premium tier is where we go deeper.
And if you'd like to support Cash & Cache without upgrading, you can — just share the newsletter with someone who'd find it useful. We've set up a referral program where every recommendation earns you access to exclusive resources.
👏 Our Biggest Asset: The Cash & Cache Community
We’ve been fortunate enough to meet a whole host of amazing creators, writers and builders on our Substack journey. Among them, a few notable ones have been part of this story right from the outset, including Mia Kiraki 🎭, Joel Salinas, Karen Spinner, Dr Sam Illingworth, Elena | AI Product Leader, Jessica Drapluk, Karo (Product with Attitude), Jose Antonio Morales, Daria Cupareanu and Anastasia | ModernMomPlaybook.
And there are wonderful creators we have met on this space along our journey, either through some official collaborations or, simply, conversations that sparked interesting discourse, including Juan Salas-Romer, Marcela Distefano, Anna | how to boss AI, Cristina, Joshua Davis 🤝, Dheeraj Sharma, Edge Of Power, Petar Dimov, Ozeco, Alena Gorb, Jenny Ouyang, The Strategic Linguist, Wyndo, James Presbitero, Bechem Ayuk, Matej Pretković, Vitalii Nechyporenko, Joe Mills, Saurabh Dalvi, Farida Khalaf, Michael Spencer, ToxSec, Aisha Imtiaz, Finn Tropy, Dave Friedman, Sumant Thakur, Phaetrix, Alex Randall Kittredge, Esha Pathak, Hodman Murad, ClariSynth, Priank Ravichandar, Tiffany Dougherty, Lile Mo, Aria Builds (and many others which my finite memory cannot fathom at the moment). We cannot thank you enough for being our inspiration and cheerleaders on this platform.
Cash & Cache has grown because of you. Not because of an algorithm, not because of a growth hack. Because you read what we wrote, thought about it, and came back the next week. Some of you commented and pushed our thinking in directions we hadn’t considered. Some shared our work with colleagues and friends who became subscribers themselves. Some collaborated with us and trusted us with their audiences and ideas. Some showed up quietly, read everything, and never said a word — and we see you too.
Whether you upgrade today, refer a friend, or simply keep reading the free newsletter — you are the reason this exists. Every version of that support matters to us equally.
This next chapter is for all of you.
— Raghav & Ashwin.
Congrats! Substack community is lucky to have you guys and learn from your knowledge! Can’t wait to see the next exciting chapter, Ashwin and Raghav.
Excited for this new chapter of Cash & Cache! Congratulations on having built such a high quality newsletter!
