What is TLDR Newsletter?

TLDR (Too Long; Didn't Read) is a family of 16+ daily tech newsletters that deliver byte-sized summaries of the most interesting stories in technology, AI, crypto, programming, and more. Founded by Dan Ni in August 2018, TLDR has grown to serve 1.6 million+ subscribers with an impressive 46% average open rate.

What makes TLDR unique is that it's written by engineers for engineers - not tech journalists covering the industry from the outside. Every story is curated and summarized in the concise "TLDR" format that developers love, making it easy to stay informed in just 5 minutes per edition.

The Complete TLDR Newsletter Family

TLDR started as a single tech newsletter and has expanded to cover virtually every tech specialization:

Core Tech

TLDR Main - Tech, startups, programming (1.6M subs)
TLDR AI - Artificial intelligence (1.25M subs)
TLDR Crypto - Blockchain, DeFi, Web3
TLDR Web Dev - Frontend, frameworks
TLDR InfoSec - Security, vulnerabilities

Specialized Topics

TLDR DevOps - Infrastructure, CI/CD
TLDR Design - UI/UX, product design
TLDR Marketing - Growth, analytics
TLDR Product - Product management
TLDR Founders - Startup advice
+ 6 more editions in active development

The TLDR Sprawl Problem

Here's the challenge: if you're a full-stack developer interested in AI, you might subscribe to:

TLDR Main (daily) - 5 emails/week
TLDR AI (daily) - 5 emails/week
TLDR Web Dev (daily) - 5 emails/week
TLDR InfoSec (weekly) - 1 email/week
Total: 16 TLDR emails per week

Each edition takes 5 minutes to read. That's 80 minutes per week on TLDR alone—before you add Morning Brew, Hacker Newsletter, or any other tech sources.

Plus, many stories appear in multiple editions. An AI model release might be covered in TLDR Main, TLDR AI, and TLDR Web Dev - meaning you read about it three times.

Who Founded TLDR?

TLDR was founded by Dan Ni, a serial tech entrepreneur who previously founded and sold a developer tools startup. Dan started TLDR in August 2018 as a passion project - he wanted a newsletter that would give him the tech news he cared about without the fluff.

The growth has been remarkable: Dan grew TLDR from 0 to 130,000 subscribers in the first 20 months. By early 2023, TLDR hit the 1 million subscriber milestone. Today, the flagship newsletter serves 1.6 million readers, with TLDR AI adding another 1.25 million.

What Tech Professionals Say

"I love TLDR but couldn't keep up with every vertical. Readless gives me one TLDR-on-steroids email I actually finish."

— Nate R., Senior Platform Engineer

"Subscribing to TLDR Main, AI, and Web Dev was 15 emails/week. Half the stories were duplicates. Readless fixed that immediately."

— Maya T., ML Engineer

The Information Overload Problem

According to recent research, 80% of global workers experience information overload, and the amount of global data is expected to reach 181 zettabytes by 2025. With 376 billion emails sent daily, newsletter overload is a real productivity drain.

TLDR's 16+ editions are valuable, but they contribute to the problem. Readless solves it by consolidating without sacrificing completeness.
