The 10 Best Newsletters for Fintech Founders in 2026

Most fintech writing is aimed at investors deciding what to fund and bank executives deciding what to buy.

‍

Very little of it is written for the person actually making the build decisions.

‍

That's a problem when you're choosing a payments processor, reading a bank partner's term sheet, or deciding whether your MVP is safe to put real money through.

‍

The newsletters below do that. For each one: who writes it, how often it lands, what it costs, and the kind of decision it'll help you make.

‍

What makes a fintech newsletter worth subscribing to

‍

Before the list, it's worth naming what you're screening for. Here's what to look for:

‍

• A writer with operating history: Someone who has built, shipped, or regulated the thing they're writing about will notice details a reporter won't. Check the About page for what they did before they started writing.
• Analysis over aggregation: A list of links is easy to produce and easy to skip. You want someone who tells you why a story matters and what it changes.
• A consistent format: Predictable structure means you can skim an issue in two minutes and go deep only when it's relevant to you. That's what makes a newsletter survivable long-term.
• Relevance to your stage: A lot of excellent fintech writing is aimed at scaled companies and public markets. If you're pre-seed to Series A, some of it is genuinely interesting and none of it is actionable. Be honest about the difference.
• A cadence you can keep up with: Three thoughtful issues a month you actually read beats a daily you archive unopened.

The 10 best newsletters for fintech founders

‍

1. Due Diligence

‍

Written by: Sam Corso, founder of TechSuite, fractional CTO with 10+ years in fintech engineering

‍

‍Cadence: Per issue, one story

‍

‍Cost: Free

‍

‍Best for: Non-technical founders who need to evaluate technical and vendor decisions they can't fully audit themselves

‍

Due Diligence takes one fintech story per issue (a deal, a lawsuit, a product launch, an accusation) and breaks down what happened, what's underneath it, and what it means for what you're building. Every issue follows the same four sections: what happened, the company's defense, what's under the hood, and what it means for you.

‍

It's number one on this list because it's the only newsletter here written from inside the build.

‍

Sam founded and led the Carrier Integrations team at Canopy Connect and now runs an embedded engineering practice for fintech startups from pre-seed to Series A, which means he sees the corners that get cut and the deals that go sideways up close.

‍

When a fintech blows up, most coverage tells you the company failed. Due Diligence tells you which specific engineering or partnership decision failed, and how to check whether you've made the same one.

‍

That's the practical payoff for a non-technical founder: you get the pattern recognition that usually takes years of building to develop, in about ten minutes a month. It's also useful reading for fintech CTOs and product leads at early-stage companies, and for the investors and operators working alongside them.

2. Fintech Business Weekly

‍

Written by: Jason Mikula, previously at Goldman Sachs, LendUp, and Enova

‍

‍Cadence: Weekly

‍

‍Cost: Free, with a paid tier for the full archive

‍

‍Best for: Anyone whose product touches a partner bank, a lending license, or a regulator

‍

If your product involves a sponsor bank, a BaaS provider, or any kind of consumer lending, this is the closest thing to required reading. Mikula covers banking, fintech, and crypto with a heavy focus on regulatory action and enforcement, and he reports out stories rather than reacting to them.

‍

The reason it matters at your stage: bank partnership and compliance failures are the most common way early fintechs lose a quarter (or a company), and they're almost always visible in enforcement patterns months before they hit you. Reading this weekly is a cheap way to see what regulators are actually punishing right now.

3. Fintech Takes

‍

Written by: Alex Johnson

‍

‍Cadence: Twice weekly

‍

‍Cost: A mix of free and premium content

‍

‍Best for: Understanding fintech business models and unit economics

‍

Johnson writes data-informed analysis that gets past surface-level news into the strategic and operational dynamics of fintech companies, covering things like Banking as a Service, BNPL, and embedded finance. If you've ever tried to explain to an investor exactly how your product makes money and where the margin actually sits, this is the newsletter that gives you that vocabulary.

‍

He also co-hosts the Fintech Recap podcast with Jason Mikula, so subscribing to both gives you a nice monthly audio summary of what you may have skimmed.

4. Fintech Brainfood

‍

Written by: Simon Taylor, co-founder of 11:FS

‍

‍Cadence: Weekly

‍

‍Cost: Free

‍

‍Best for: Seeing where the industry is heading, especially on AI, stablecoins, and payments

‍

Brainfood is read by 45,000+ people at banks, fintechs, and VC firms, and it's the best single source for the "where is this all going" question. Taylor takes the week's biggest events and gets under the skin of what's happening, with a current focus on AI in financial services, stablecoins, and payments infrastructure.

‍

Use this one for positioning rather than execution. When you're writing a pitch deck slide about why now, Brainfood is where you'll find the trend framing that investors are already reading.

5. Net Interest

‍

Written by: Marc Rubinstein, former hedge fund manager

‍

‍Cadence: Weekly

‍

‍Cost: Free, with a $30/month paid tier

‍

‍Best for: Understanding how financial businesses actually make money

‍

Rubinstein goes deep on one financial topic or trend per week, landing every Friday. It's less fintech-startup news and more financial-services fundamentals, written by someone who spent ten years as a hedge fund partner and, before that, was a top-rated bank analyst. Over 100,000 people subscribe.

‍

This is the newsletter that teaches you the underlying economics of the industry you're building in: how banks earn, how spreads work, why incumbents behave the way they do. That's genuinely useful when you're deciding whether to compete with an incumbent or partner with one. The free tier gives you the main feature piece each week, which is plenty to start with.

6. Money Stuff

‍

Written by: Matt Levine, Bloomberg Opinion

‍

‍Cadence: Three times weekly

‍

‍Cost: Free to subscribe

‍

‍Best for: Financial plumbing, market structure, and the funny, instructive ways finance breaks

‍

Money Stuff isn't a fintech newsletter, and that's the point. Levine explains Wall Street, finance law, and market structure clearly enough that you'll finally understand the mechanics your product sits on top of. He's a former lawyer and investment banker, and he writes about complicated things without making you feel stupid.

‍

If you're building in capital markets or anything involving securities, this one moves from nice-to-have to essential.

7. This Week in Fintech

‍

Written by: A contributor network

‍

‍Cadence: Weekly

‍

‍Cost: Free to subscribe

‍

‍Best for: Funding activity and a global market scan

‍

Founders, investors, and operators read This Week in Fintech to keep up with global market dynamics and funding activity. It's the roundup format done well, and it's the fastest way to track who raised what, which matters more than founders sometimes admit.

‍

Funding news tells you which categories are getting priced, who your emerging competitors are, and which investors are currently writing checks in your space.

8. The Fintech Blueprint

‍

Written by: Lex Sokolin

‍

‍Cadence: Regular, with multiple tiers

‍

‍Cost: Free content plus multiple paid subscriber tiers

‍

‍Best for: Crypto, DeFi, and the intersection of AI and financial infrastructure

‍

Sokolin covers a wide range of fintech topics, from super apps to decentralized finance, with a subscriber base north of 200,000. He was Chief Economist at ConsenSys, the company behind MetaMask, and previously built and sold a B2C roboadvisor and a fintech equity research practice, so the analysis comes from someone who has operated rather than just observed.

‍

If you're building anything on-chain, or your product roadmap has a crypto rails question in it, this is the most consistent long-form analysis available on that intersection.

9. a16z Fintech

‍

Written by: The fintech team at Andreessen Horowitz

‍

‍Cadence: Monthly

‍

‍Cost: Free

‍

‍Best for: Reading the investor lens directly

‍

The a16z fintech team aggregates their individual observations into a combined monthly newsletter, along with pieces on larger themes and the companies they invest in. It's worth subscribing for a simple reason: you're going to raise from people who think like this, and reading their theses in their own words is the cheapest possible fundraising prep.

‍

Just read it knowing what it is. It's smart analysis and it's also a marketing asset for a venture firm. Both things are true.

10. Sifted

‍

Written by: The Sifted editorial team

‍

‍Cadence: Weekly (the fintech newsletter lands Tuesdays)

‍

‍Cost: Free to sign up, with some newsletters reserved for Sifted Pro subscribers

‍

‍Best for: European fintech and tech news

‍

Sifted focuses specifically on tech in Europe, and it runs a dedicated fintech newsletter covering neobanking, BNPL, payments, and the European startup scene. It's worth subscribing to if you have European users, European investors, or a European expansion plan. Regulatory and product patterns often show up in the EU and UK before they reach the US, so it can function as a preview of conversations you'll be having in a year.

Getting the most out of fintech newsletters

‍

Ten newsletters sounds like a lot until you set them up properly. Here's a system to try: 

‍

1. Start with three, not ten. Pick Due Diligence for build decisions, Fintech Business Weekly for regulatory exposure, and one of Fintech Takes or Brainfood depending on whether you want business model depth or trend framing. Add more only once those three feel easy.
2. Route them out of your primary inbox. Create a dedicated email address or a Gmail filter and label so newsletters land in one place. This is the single change that makes the difference between reading them and archiving them guiltily.
3. Give yourself one standing block a week. Thirty minutes, same time every week. Skim everything, read one thing properly. Friday afternoons work well because most weekly issues have landed by then.
4. Keep a running note of anything that applies to you. When an issue describes a failure mode or a compliance requirement that touches your product, write one line in a doc. Over a few months that becomes a genuinely useful risk checklist built from other people's expensive mistakes.
5. Unsubscribe honestly. If you've archived four issues in a row unread, that newsletter isn't for you right now. Let it go and reclaim the attention.

Frequently asked questions

‍

What's the best fintech newsletter for a non-technical founder? Due Diligence, because it's written specifically to give founders the technical pattern recognition they don't have yet, using one real fintech story per issue rather than abstract advice. Pair it with Fintech Business Weekly if your product involves a bank partner or a lending license.

‍

Are these fintech newsletters free? Most are free to subscribe to. Due Diligence, Fintech Brainfood, a16z Fintech, and Money Stuff are free. Fintech Business Weekly, Fintech Takes, Net Interest, and The Fintech Blueprint offer free content with paid tiers for deeper analysis and full archives.

‍

How many newsletters should I actually subscribe to? Three to five. Beyond that, most founders stop reading them entirely. It's better to read three carefully than to skim ten.

‍

Do fintech newsletters help with fundraising? Indirectly, yes. Reading a16z Fintech and Fintech Takes gives you the framing and vocabulary investors are already using, which makes your pitch easier for them to place. Reading Due Diligence and Fintech Business Weekly helps you answer the technical and compliance diligence questions that come after the first meeting.

‍

One last thing

Newsletters are a low-cost way to build judgment about decisions you can't personally audit yet. They aren't a substitute for having someone technical in the room when you're choosing a payments processor or shipping money movement for the first time.

‍

If you're at that point, Due Diligence is a good place to start, and TechSuite works with fintech founders on exactly those decisions.
