"I subscribe to SaaStr, Lenny, a16z, Point Nine, Tomasz Tunguz, Dave Kellogg, and 20 more. That's 150+ minutes weekly. I can't keep up, but I can't unsubscribe either."
"The relentless overload that's wearing us down is generated by a belief that 'good' work requires increasing busyness—faster responses to email and chats, more meetings, more tasks, more hours."
— Cal Newport, Author of Deep Work

Yes. With Readless Pro, you can build a PM-only digest containing Lenny's Newsletter (1M+ subscribers), Mind the Product, Gibson Biddle, and ProductLed while excluding funding and sales content. Set up sender-level filters to route any PM-focused newsletter into its own digest. Perfect for product managers who want focused product intelligence without the noise.
Absolutely! Include High Scalability, Pragmatic Engineer, SaaS architecture newsletters. Readless consolidates technical + business newsletters for full-stack SaaS awareness. Many CTOs subscribe to 15+ newsletters across engineering and business—we consolidate them all.
Forward digest to team Slack or create 'SaaS Weekly Highlights' channel. Many SaaS companies have all execs using Readless, sharing relevant sections with their teams. Some teams create themed digests: one for engineering, one for product, one for growth.
Yes! If you subscribe to paid newsletters (like Lenny's Newsletter with 18,000 paid subscribers or The Information), forward them to @mail.readless.app. Your digest includes both free and paid newsletter summaries, with links to full paid content you're already paying for.
Pro plan: Create multiple digests. 'SaaS Digest' (SaaS newsletters), 'Fintech Digest' (fintech newsletters), 'General VC' (broad VC newsletters). Organize by investment thesis. Each digest can have different delivery schedules.
Following SaaStr or Lenny alone gives you a single perspective. The SaaS ecosystem has 30+ essential newsletters covering different angles. Readless consolidates SaaStr, Lenny's Newsletter (1M+ subscribers), Demand Curve (100k+ subscribers), Tomasz Tunguz, a16z, and 25 more into one daily digest. You get comprehensive SaaS intelligence instead of single-source bias.
The average B2B professional subscribes to 8-12 industry newsletters, based on 2025 industry research. SaaS founders and product managers typically subscribe to 15-25 newsletters to stay competitive, translating to roughly 75-150 minutes of daily reading. With ~85% of business software projected to be SaaS by end of 2025, staying current on the ecosystem is a full-time reading job without consolidation.
You'll get insights on CAC (Customer Acquisition Cost), LTV (Lifetime Value), MRR/ARR growth rates, churn benchmarks, Rule of 40, sales cycle length (average 134 days for B2B SaaS in 2025), conversion rates, and efficiency metrics from sources like OpenView, SaaS Capital, and Maxio's annual benchmark reports.
Absolutely! Most SaaS professionals read SaaS-specific newsletters (Lenny, SaaStr, Demand Curve) AND general business newsletters (Morning Brew, Axios, The Information). Readless consolidates all of them. Create one 'Morning Brief' with everything, or separate 'SaaS Deep Dive' and 'General Business' digests.
When the same funding round is covered by multiple newsletters (e.g., a $50M Series B appears in TechCrunch, The Information, Strictly VC, and SaaStr), our AI detects the duplication and consolidates it into one entry with 'Sources: 4 newsletters.' You read it once, not four times.
Lenny's Newsletter has 18,000 paid subscribers at $15/month ($180/year) with a 4-5% conversion rate, indicating high value. Readless doesn't replace the full content—you still need to subscribe—but we consolidate the summaries so you can decide what to read in depth. Many users save 60-90 minutes daily while staying fully informed.
The best cadence depends on your role. SaaS founders should choose daily digests at 6 AM to catch funding trends and competitive intel before meetings. Product managers do well with 3x weekly (Mon/Wed/Fri) for deeper reading. Investors need daily for deal flow. Growth marketers often run morning plus evening digests. Readless Pro supports all schedules and up to three separate digests per account.
Get Lenny's Newsletter (1M+ subs), Demand Curve (100k+), SaaStr, and 25+ more in one 15-minute daily digest. Start your free 7-day trial.
