Founders, stop paying for cabs, coffee, and client lunches from your own pocket. As founders, we constantly pay small company expenses - cab rides, coffee meetings, team lunches - and then forget to reimburse ourselves. It’s basically an unofficial "founder tax”! That hit home 🎯 - because I’ve been there. At @CashBook_App : UPI Wallets for Employees, we decided it’s time to fix this. Introducing our Founder Launch Plan 🎊 FREE UPI wallets for founders for the first full year 🗓️. Load your wallets from your company’s current account, spend instantly on cabs or client lunches and effortlessly attach invoices right then and there. No reimbursements, no hassle, no forgotten expenses ✅ After the first year, you’ll have the option to renew at a simple, affordable monthly price. Ready to stop mixing personal funds with company spends? Drop a 🚀 below, and we’ll set you up within minutes!

@RajanAnandan True at the rail level, though 'losing relevance' understates what's actually happening. deeper shift: credit cards fell from 43% to 21% of India's digital payment value between 2018 and 2024. UPI is bypassing the card abstraction entirely, not just swapping the logo on it.

Two global companies, one with $690B market cap and the other with a $470B market cap, are rapidly losing relevance in the world's most innovative Fintech market. 1B users. That is what is at stake.

Fitness tracker x Claude code I love WHOOP. The sleep tracking, recovery scores, strain data elite level stuff. But here's what's always bugged me: You can't snap a photo of your meal and log it. You can't ask "why did my recovery tank today" and get a real answer. You can't cross-reference your nutrition with your HRV trends. The data is incredible. But it stays trapped in charts. YOU have to be the analyst. So I connected my WHOOP to Claude using MCP Model Context Protocol. Basically gave AI a direct line to my biometrics. Now? Point your phone camera at your plate. AI breaks down the calories, protein, carbs, fat no manual entry, no barcode scanning. Just vision. Ask it to analyze your sleep for the past week. It cross-references your HRV, resting heart rate, sleep stages, strain, SpO2 and tells you what's actually going wrong. Not just numbers. Insight. It caught patterns I'd been staring past for weeks. Correlated things across sleep, recovery, training, and nutrition that no single dashboard would ever show you together. The setup? A Python MCP server, WHOOP's API, and Claude. 15 minutes. No new app. No extra subscription. The gap between "I have data" and "I have insight" just collapsed. And honestly? The gap between a $500/month health coach and a DIY setup is collapsing too. I built a version of it on a Sunday afternoon. We're closer to this future than most people think. And it's going to be absolutely wild.

Meta is getting back into stablecoins. This time, they're not building Libra 2.0. They're partnering with Stripe (who acquired Bridge for $1.1B) to plug stablecoin payments into Facebook, Instagram, and WhatsApp. 3 billion+ users, dollar-pegged tokens and cross-border payments at near-zero cost. The playbook shift is what's interesting: 2019 → "We'll create our own global currency" 2026 → "We'll be the distribution layer, someone else holds the keys" Zuckerberg literally told Stripe's John Collison that Diem was dead. Now Stripe's CEO Patrick Collison sits on Meta's board. And Bridge just got OCC approval for a national trust bank charter. The timing isn't coincidental. The GENIUS Act gave stablecoins a legal framework in the US for the first time. Fidelity launched its own stablecoin. Bank of America and Citi are exploring theirs. The floodgates are open. Here's what I'm watching as a fintech founder in India: WhatsApp is already the de facto business communication tool here. If Meta rolls stablecoin payments into WhatsApp globally, the cross-border remittance and creator payout game changes overnight. India processes 14B+ UPI transactions a month domestically. But cross-border is still painful, still expensive. Stablecoins on WhatsApp could bridge that gap faster than any SWIFT upgrade ever will. The companies that figure out how to sit at the intersection of stablecoins, UPI and embedded payments are going to build the next generation of fintech infrastructure. The future of business payments isn't just digital. It's programmable.

Payments are one of the last major industries still built on rent-seeking economics. Every major industry has been disrupted over the past two decades. > Telecom evolved from expensive per-minute charges to affordable unlimited data. > Media shifted from physical CDs to frictionless streaming. > Software abandoned perpetual licenses for subscription models. Yet payments remain stubbornly unchanged with flat fees plus 2–3% per transaction, pricing structures that lack transparency and the same intermediaries extracting the same margins. For three decades, we've accepted this as inevitable infrastructure cost. That consensus is now breaking down. UPI demonstrated that peer-to-peer transfers could be instant and free. Cryptocurrency questioned why intermediaries were necessary at all. Account-to-account payment rails are now driving transaction costs toward zero. The commoditization of money movement is underway and this shift has profound implications. Payment gateways can no longer justify their position as gatekeepers. The value proposition is migrating to adjacent services credit underwriting, financial intelligence, and payment orchestration. The economic equation is inverting. The act of moving money will approach zero cost, while the ability to analyze, optimize, and leverage financial data will command premiums. & that's where the next generation of payment companies will differentiate themselves not by facilitating transactions, but by extracting insight from them.

The Humble Soundbox Revolutionized Indian Payments, Here's Why It Matters India didn't transform digital payments through sleek interfaces or expensive hardware. It did it with a simple speaker that cost ₹3,000. The soundbox solved a problem that sophisticated UX design couldn't crack which is instant, universal payment confirmation. No screen to check, no receipts to print with no room for doubt. In India's reality bustling markets, constant noise, inconsistent connectivity, varying literacy levels audio proved superior to visual confirmation. The soundbox worked everywhere, for everyone. But its impact went beyond convenience, as it fundamentally shifted merchant behavior by building trust in digital payments, eliminating disputes before they started, accelerating transaction speed and freeing merchants from constant app monitoring. This exemplifies a distinct approach to innovation which is to design for real conditions, not ideal ones and to prioritize human behavior over technical sophistication. The implications of this extend beyond payments. As voice interfaces and AI reshape commerce, the soundbox model may define the next generation of retail technology. Sometimes the most transformative innovations aren't the most glamorous. They're just the ones that actually work.

Why WhatsApp Pay Was Inevitable and Still Struggling Half a billion users. Built-in daily habit. Payments literally one tap away. On paper, WhatsApp Pay should have owned Indian digital payments from day one. Instead, it's still fighting for single-digit market share. Here's what most people miss: Having users doesn't mean you win payments. Payments aren't a convenience feature you bolt onto messaging. They're critical infrastructure. In India, that means playing by a completely different rulebook. NPCI deliberately caps market share. Regulators intentionally slow down dominance. The system is designed to prevent any single player from becoming too powerful. While everyone was predicting WhatsApp's inevitable takeover, PhonePe and GPay were building something less flashy but more valuable trust at scale. They grew methodically, not explosively. They proved reliability over reach. India chose stability over speed.. and it worked. The irony is that, the next big winner in Indian payments won't look like a rocket ship. It won't have viral growth or dramatic headlines. It'll look predictable, maybe even boring. But it'll be trusted by millions, embedded in daily life and approved by regulators who know that boring often means resilient. & In payments, boring wins.

As founders, PMs and decision makers, we chase perfect information. We believe one more deck, one more forecast, or one more conversation will finally clarify the path. We spend weeks in the 'design' phase, mapping every potential user flow, every edge case, every dependency. This is a beautiful map of a place that doesn't exist. The error is treating internal deliberation as a substitute for external discovery. You can refine your assumptions all you want, but the resolution of your internal map is capped by the lack of external signal. The market doesn't care about your flow charts, it cares about its own needs. Perfect information arrives after the contact, not before. It’s the result of a skirmish, not the precursor to one. The moment you ship the ugly, unpolished version is the moment the signal-to-noise ratio in your decision-making skyrockets. Your assumptions stop being debates and become hypotheses. True job isn't to be right the first time. It's to ensure the first moment of being wrong is inconsequential. Perfection is expensive. Proof is cheap.

The "Where is my money?" panic on UPI transaction is finally becoming a thing of the past. Unified Dispute and Issue Resolution (UDIR) system is arguably the most crucial infrastructure update since the launch of UPI, already the world's largest real-time payment network. The Problem UDIR Solved: For years, the Achilles' heel of UPI was the "payment in limbo" state and the excruciatingly manual, file-based chargeback process. Failed transactions could take 3-5 days to resolve, eroding customer trust and creating massive operational overhead for banks and merchants. How UDIR Actually Fixes Dispute Resolution: UDIR turns dispute resolution from a slow back-office mess into a fast, digital self-healing system. 1/ API-First Resolution Replaces file uploads with real-time API calls like ReqComplaint. All complaints, disputes, and refunds flow into one centralized platform. 2/ Minutes, Not Days Continuous polling and auto-updates proactively finalize failed transactions. Many cases resolve in minutes. One bank saw a 50% improvement in resolution time. 3/ Automated Consumer Protection Rule-based auto-chargebacks kick in if the beneficiary bank or merchant doesn’t respond. Complaints convert automatically by T+1 for P2P and T+3 for P2M. This creates hard, non-negotiable trust. 4/ Real-Time Refunds Manual refunds are eliminated. Merchants initiate API-based, pre-approved refunds for instant reversals, reducing customer panic and preventing unnecessary chargebacks. So, if your money is stuck, open your UPI app like BHIM, PhonePe or GPay. Go to transaction history, tap the stuck transaction, and hit Check Status.

Have you ever wondered why Payment Gateways take a 3% cut of everything you sell? For 30 years, we’ve accepted a broken system. If you buy a coffee or a subscription online, a middleman (banks, processors) takes a bite out of the transaction usually about Rs ~3 plus 2-3%. That doesn't sound like much, but it makes micropayments impossible. You can't sell a digital article for Rs 1 if the fee is Rs 3 you’d lose money instantly. But this week, the internet finally fixed a mistake from 1997. Back then, the creators of the web built a special signal called HTTP 402. It was supposed to let us send money as easily as we send emails. But the technology wasn't ready... until now. Thanks to a new protocol called X42 (by Coinbase), that sleeping switch has finally been flipped on. Here is why this matters to you: 1. Micro-transactions: You can finally pay pennies for things instantly without high fees. 2. No Middlemen: The 3% "gateway tax" disappears. 3. The AI Economy: Imagine your AI assistant paying another AI a fraction of a cent to book your travel or find data.

The 10x Engineer is dead. Long live the 10x Orchestrator. For the last 20 years, software was designed to make humans slightly more efficient. We bought tools to help us type faster, calculate better and stay organized. but 'Agentic AI' changes the fundamental structure of labor. We’re entering a phase where a team of 3 can exert the leverage of a traditional organization of fifty. The bottleneck is no longer headcount, it’s system design. let's be real for a second, if you're building your company using 2020 playbooks, you're already moving too slow. The advantage doesn't go to whoever hires the most people; it goes to whoever integrates the most effective agents into their workflow. We aren’t just using software anymore. We’re hiring it.

I asked Nano 🍌 Pro what an Avengers Expense Review Meeting looks like ....and let's just say, Nano🍌 Pro ate. @GeminiApp @Avengers @MarvelStudios @NanoBanana

@ShubhamDeol Awesome 🙌

Text ➡️ dotLottie Animation. Instantly. ✨ I built this Text-to-Lottie engine using the new Nano Banana Pro for image generation and Gemini Flash Lite for vision detection. It exports optimized .lottie files ready for the web. I pair-programmed the whole thing with Antigravity.

STOP! You are paying for a 747 when all you need is a helicopter. Finance leaders are being sold this dangerous lie that your expense management tool needs • 5,000 features, • complex ERP integrations • a 6-figure implementation cost just to manage 10-50 employees. This is probably the biggest myth perpetuated by legacy vendors to lock you into their ecosystem. and it’s costing you more than money. The REAL cost is NOT the subscription fee. It’s : > the 4 hours a week your ops team spends untangling confusing approval chains. > the 3-day delay in reimbursement that frustrates your top sales talent. Which is why we built CashBook UPI wallets (@CashBook_App ), because I watched companies spend 50 lacs on a system, only to use 10% of its functions. That 90% overhead just is a complexity debt. The future of FinOps is invisible and instant & not bulky and expensive AND if your expense tool requires an instruction manual, then it’s probably already broken. :/

We just pushed a bunch of upgrades inside CashBook that make day-to-day finance work a lot smoother. Here’s everything that’s new: 👇

Domestic payment rails are turning into geopolitical battlegrounds, just look at what’s happening with Pix (Brazil’s equivalent of UPI) I came across something that immediately caught my attention, which is that the U.S. Trade Representative (USTR) has launched a formal investigation into Brazil’s digital trade and right at the center of it all is Pix, their instant payment system. Naturally, I went down the rabbit hole and the core issue is actually pretty straightforward.. It's that Pix is growing so fast, and becoming so dominant, that it’s starting to seriously threaten the business models of big American players (the Visas, Mastercards, and Apple Pays of the world.) Brazil's response to this pressure was equally striking. They didn't back down; they fired back with a passionate national campaign slogan: “O PIX é do Brasil.” i.e ( Pix belongs to Brazil. ) This entire episode crystallized a fundamental truth for me, which is that when a free, instant rail grows faster than every paid rail, someone’s profit pool is guaranteed to shrink and naturally, that "someone" is going to push back. Then who loses the most? > Banks: Because Pix directly cannibalizes the lucrative profit centers of interchange fees, Merchant Discount Rates (MDR), and the card credit float. > Acquirers: Because Pix completely bypasses the Point-of-Sale (POS) economics and the physical terminal infrastructure they control. >Visa and Mastercard: Because Pix is rapidly becoming the undisputed "default rail" for everyday, high-volume transactions, sidelining the legacy card networks. This disruption caused by Pix is a direct cannibalization of revenue streams of established entities.. So in my view, the "attacks" on Pix are anything but random. Systems being disrupted always fight back. The fraud narratives, the fearmongering, the regulatory scrutiny all of it is a tactic in a larger war.

Have you seen second-gen entrepreneurs taking over family businesses lately? They’re doing things differently. For their parents, business was about trust and hard work relationships built over years, every detail stored in memory, every transaction written by hand. For this new generation, business is about systems and visibility. They’ve grown up watching their parents do everything themselves and they’re saying, “There has to be a better way.” So, they digitize FAST. > They build WhatsApp catalogs instead of print brochures. > They track expenses daily instead of tallying at month-end. > They use mobile tools to manage what used to take piles of registers. It’s a quiet kind of revolution happening in small towns, godowns, and corner offices across India. And it’s beautiful to watch because for the first time, Indian family businesses aren’t just being passed down they’re being transformed too.

@dharmeshba Looking forward to it

My most personal and exhaustive piece dropping tomorrow on my Substack! Excited, nervous.

Every time the word stablecoin comes up in India, someone says “Why do we need that? We already have UPI.” Fair point. UPI is one of the most efficient domestic payment systems ever built, but let’s be real, UPI is a local rail and stablecoins are a global rail. UPI is perfect for kirana stores, domestic businesses, and peer-to-peer payments, but it stops at the border. If you’re a freelancer, exporter or a digital entrepreneur you already know the pain of receiving money from abroad. > takes 3–5 days of waiting, 3–6% in fees, FX delays and Compliance friction. Stablecoins are the “UPI for the world.” They settle in minutes, 24×7, across borders at almost zero cost and because they’re pegged to INR or USD, the value stays stable. Now imagine what that unlocks: 1. Instant escrow for exports :- > a textile exporter in Surat ships fabric to Paris, the moment the goods are delivered, payment hits his account, all w/o any follow-ups or delays. 2. Real-time crop insurance :- > a farmer in Idukki doesn’t have to file insurance claims anymore, the system reads real-time rainfall data, sees the drop, and triggers an instant payout. 3. Instant freelancer payments :- > a designer in Bengaluru finishes a project for a SF based client, gets $500 within minutes, directly in a digital wallet, and cashes out via UPI before even leaving the cafe. None of these were possible in the fiat world. But they are already happening on top of stablecoins globally.

China Is Quietly Rebuilding the Global Financial System Over the last few years, the People’s Bank of China has quietly become the largest buyer of gold in the world while selling off U.S. Treasuries. At the same time, China launched the Shanghai Gold Exchange, now the biggest physical gold marketplace on Earth. They’re even building a “Gold Corridor” a network of vaults across BRICS countries that lets nations holding yuan exchange them for real gold. basically, China is giving its currency something that the dollar lost a long time ago, Trust. Gold can’t be frozen, printed, or defaulted on. And since July 2025, gold has been reclassified as a Basel III Tier-1 asset, meaning it now counts the same as cash or treasuries on bank balance sheets. The next step? If gold becomes an HQLA (High-Quality Liquid Asset), banks will be able to lend and borrow against it, just like U.S. treasuries. That’s when everything changes. It would mean countries could fund development ports, factories, infrastructure without ever touching the dollar or the IMF. This “Gold-Backed Financial System” would let China and its partners create an alternative to the Western system, one based on real collateral instead of paper promises. And while China builds around gold, the U.S. might counter with digital assets, stablecoins or Bitcoin. For the first time in history, the world could have two competing versions of money one backed by gold, another by code, The implications for gold, commodities, and crypto could be Massive.
