I’m not doing a Black Friday sale

Organic SaaS Growth • 0 implied HN points • 28 Nov 25
💼 Business Product
  1. Black Friday-style discounts are being avoided because they turn serious products into cheap commodities.
  2. A hands-on SaaS Growth OS is being offered for founders stuck at $1k–$15k MRR to diagnose bottlenecks, plug retention leaks, and build one scalable acquisition channel — it’s not a video course or a swipe file.
  3. A Founding Member cohort opens Tuesday, December 2 at 10 AM EST with only 15 spots, lower pricing, and personal email support; reply "Interested" for first access.

ARR is dead. Long live VRR

Experiments with NLP and GPT-3 • 0 implied HN points • 27 Dec 25
💼 Business Product
  1. ARR can overstate the value of AI products because it counts one-off or novelty-driven payments; VRR measures sustainable revenue by applying a Utility Decay Coefficient based on workflow integration, model independence, and churn.
  2. Investors should run cohort utility audits and calculate a VRR gap using metrics like boring-day ratio, month-5 retention, integration depth, and model independence to separate ‘vibe’ revenue from durable revenue.
  3. VRR changes valuation logic by penalizing short-lived, novelty revenue to avoid inflated paper valuations and focus on products that create real habits and deep integrations.

January 7th: we bring the community together for mutual support and mutual education

Respectful Leadership • 0 implied HN points • 19 Dec 25
💼 Business Product
  1. A community meetup can deliver concentrated, practical business education that teaches what investors want, how to manage personal and company finances, and the basics of product development.
  2. Product work now demands attention to ethics and AI, and UX-focused practitioners can show how to build responsible, user-centered products that scale.
  3. Practical frameworks for leadership and people management, plus founder stories and networking, give attendees concrete tools and peer support to grow their ventures.

Curious futures (KGhosh) • 0 implied HN points • 11 Jan 26
🕹 Technology Product
  1. AI often produces imaginative but unreliable outputs that can be misleading or false, and those hallucinations can trigger real-world confusion and disruption.
  2. Organizations need human-led guardrails like futures literacy, workshops, and pragmatic labs to turn AI creativity into useful work and to prevent chaotic or harmful decisions.
  3. AI is already reshaping jobs, business models, and culture, prompting investor attention and community responses like repurposing spaces and experimenting with new social practices.

Les mocassins de quelqu'un d'autre

Squirrel Squadron Substack • 0 implied HN points • 26 Jan 26
🕹 Technology Product
  1. Automated status messages can be contradictory, for example saying a device is repaired while warning the keyboard or screen may not work, which confuses customers.
  2. If engineers or technicians don’t use and test the system themselves, they won’t notice silly or harmful messages that slip through.
  3. This gap between automation and human oversight can cost time, trust, and business; either update the system or make sure people regularly use and correct it.

🐿️ Pay Your Attention To This - The Insanely Profitable Tech Newsletter

Squirrel Squadron Substack • 0 implied HN points • 09 Feb 26
🕹 Technology Product
  1. Many products end up with absurd, unusable features because no one on the team ever pays attention to real users or real-world use.
  2. Make the customer’s needs omnipresent: short release cycles, engineers talking to customers, and seeing real usage expose design problems quickly and stop bad decisions spreading.
  3. Create a culture where anyone can flag absurdity by encouraging psychological safety and cross-functional responsibility so problems get fixed instead of ignored.

🐿️ Tracer Bullets - The Insanely Profitable Tech Newsletter

Squirrel Squadron Substack • 0 implied HN points • 06 Feb 26
🕹 Technology Product
  1. Treat mistakes like tracer bullets: run cheap, fast experiments that will often be wrong so you get immediate feedback and learn quickly.
  2. Don’t stop at technical fixes — use failures to change culture and processes so you root out over-optimism, whitewashing, and the normalization of bad practices.
  3. Build disciplined rapid-learning loops: ask why repeatedly, do frequent post-mortems, and update norms so teams converge on the right results and make mistakes harder to repeat.

S06 - EP 02 --> Pirates in the Navy: Recruiting the crew

Product Hustle Stack Newsletter • 0 implied HN points • 14 Feb 26
💼 Business Product
  1. Hire for persistence, focus, and lateral thinking over pedigree or domain expertise; creative audacity and the ability to move fast are what win 0-to-1 work.
  2. Use a special-ops hiring loop that bypasses standard bureaucracy so the core team vets candidates and you hire people the team would follow into battle, then give them clear goals and CEO-like ownership.
  3. Treat recruiting as risk management: give the pirate team executive air cover and sovereignty, diplomatically manage navy egos to avoid sabotage, and don’t force early reintegration into regular processes.

#49 A GTM Framework for the New Epoch

Organic SaaS Growth • 0 implied HN points • 20 Feb 26
💼 Business Product
  1. Shift GTM from volume to precision: prioritize meaningful, contextual outreach and use AI to improve thinking and targeting, not just to scale activity.
  2. Run high-signal outbound with an adaptive, quantifiable ICP and signal-based qualification; let AI assist but keep humans in the loop to avoid burning TAM and improve conversion.
  3. Align multi-channel inbound with a machine-readable Strategic Manifest so autonomous agents produce consistent, high-trust content, and embed human oversight plus feedback loops to refine strategy over time.

Complexity Cascades: A Lesson Re-Learned through Building with AI

Front Left • 0 implied HN points • 13 Feb 26
🕹 Technology Product
  1. Vague goals and prompts cause complexity to explode, so define clear objectives, boundaries, and success criteria before asking for reviews.
  2. AI will mirror the complexity you give it, so act like the expert: do the hard thinking internally and ask the AI for focused, constrained help.
  3. Complexity is contagious and avoidable — interrupt runaway design early by questioning whether a system should exist, simplifying the problem, and realigning on the real objective.

🐿️ Management by Embarrassment - The IPT Newsletter

Squirrel Squadron Substack • 0 implied HN points • 26 Feb 26
💼 Business Product
  1. Real, specific external threats or immovable deadlines motivate teams more effectively than made-up goals because they create meaningful consequences people want to avoid.
  2. Put responsibility in small, cross-functional teams with one engaged leader so work can’t be passed around and accountability rests where the results happen.
  3. Make progress highly visible with frequent demos and scorecards so the importance is reinforced, rapid corrections are possible, and public accountability (within a safe culture) drives delivery.

Nobody Has This Figured Out

On Engineering • 0 implied HN points • 27 Feb 26
🕹 Technology Product
  1. Companies are shifting toward platform-style products where customers compose features from core primitives, which reduces the number of people needed to build and support those features. This is a strategic architectural change, not just a short-term cost cut.
  2. Many recent layoffs are as much a correction for pandemic-era overhiring as they are about intelligence tools, and AI is often used as a convenient narrative; the quieter impact shows up as unfilled requisitions and paused hires rather than dramatic firings.
  3. Engineers can’t just “build” and expect success — competition is fiercer and the moat is now distribution, trust, and business skills, so actively learning adjacent skills, experimenting, and adapting is wiser than staying passive.

why finding real problems is everything

Organic SaaS Growth • 0 implied HN points • 25 Feb 26
💼 Business Product
  1. Most growth problems in early-stage SaaS aren't what they first look like; surface symptoms often hide the real issue.
  2. Founders often keep trying new tactics and channels because they haven't diagnosed where growth is actually breaking.
  3. The right move is to find the root cause of the slowdown and fix that instead of constantly experimenting with new growth hacks.
