AI agents slash 40% of staff at Block, trigger SaaSpocalypse

Friday, April 3, 2026 · from 4 podcasts, 7 episodes
The AI Daily Brief: Artif…The AI Daily Brief: Artif…This Week in AIThe AI Daily Brief: Artif…The a16z ShowThis Week in StartupsThe AI Daily Brief: Artif…
  • Block cut over 40% of its dev staff as agentic AI broke the link between headcount and output.
  • AI's second moment is here: workable agentic systems are replacing entire SaaS departments, causing a valuation collapse.
  • Enterprises are failing, spending 93% of AI budgets on infrastructure while neglecting essential staff training.

The law of corporate scaling is dead. For decades, more revenue required more people. Block executive Owen Jennings announced that law broke in the final weeks of 2025. His company responded by cutting its workforce by over 40%, with the deepest cuts in software development, where AI now handles coding.

Jennings told the a16z Show that Block is not writing code by hand anymore. Internal tools like Builder Bot autonomously write, test, and merge code, enabling designers and product managers to ship their own features. The company now operates with squads of one to six people instead of large teams, cutting management layers by more than half.

This isn't just an internal optimization; it's an extinction event for the old software economy. Nathaniel Whittemore of *The AI Daily Brief* calls it the 'SaaSpocalypse.' Investors are fleeing public software stocks, realizing that when a tool like Claude can automate entire departments, the per-seat revenue model of traditional SaaS collapses. Anthropic now captures 70% of first-time enterprise AI buyers as companies build entire workflows around agents.

Owen Jennings, The a16z Show:

- There's been this correlation between the number of folks at a company and the output from the company for decades and decades.

- I think that basically broke.

Yet most companies are flying blind into this shift. Whittemore's research shows a massive capability overhang: what AI can do far outstrips what businesses capture. A Deloitte study found that 93% of AI budgets go to infrastructure, with only 7% allocated to training the people who must use it. This creates a dangerous mismatch where 72% of leaders think training is adequate, but 55% of employees disagree.

The path forward is moving from chatbots to managed agent workforces. Developers like Shubham Sabu treat AI agents like human staff, onboarding them with specific context and putting them on cron schedules to work autonomously. The new infrastructure is portable 'skills' - markdown folders that act as executable playbooks - replacing locked-in custom GPTs.

The logical endpoint is already live. A firm called Pulsia reached $6 million in revenue with a single founder and no human staff. The zero-employee company is no longer a thought experiment. It's a weekly dashboard.

How to Build a Personal Context Portfolio and MCP Server • Apr 3

  • Agent deployments are fundamentally data problems because enterprise data was never structured for AI consumption.
  • Notion's database agents act as librarians that automatically keep databases up to date using workspace and web context.
  • Andrew Ng's Context Hub is an open CLI that lets coding agents share feedback on API documentation to refine it for everyone.
  • Claude's approach to memory import was a simple prompt asking ChatGPT to write out everything it knew about a user.
  • A personal context portfolio is a structured set of markdown files that act as machine-readable API documentation for a person.
  • KPMG embedded AI and agents across its entire enterprise operating model, not as a tech initiative but as a total shift.
  • Blitzy helped a public insurance provider complete a 13-month payments processing application project in six weeks.
  • Blitzy helped a vertical SaaS provider extract services from a monolith 21 times faster than pre-Blitzy estimates.
  • Robots and Pencils uses its RoboWorks platform to help teams deliver initial launches in as little as 45 days.
  • A personal context portfolio template includes files for identity, roles, projects, team relationships, and communication style.
  • The decision log file in a context portfolio records past decisions and reasoning, which is valuable for future agent recommendations.
  • An MCP server is a program that responds to AI tool requests by listing available resources and providing their content.
  • The main work in building an MCP server is often troubleshooting errors like port conflicts or file naming mismatches.

Agent Skills Masterclass • Apr 2

  • Nufar Fargas Bar defines agent skills as folders holding instructions, scripts, and resources that provide AI tools and agents with actionable playbooks for tasks.
  • Agent skills operate in two modes: agents can automatically discover and invoke them, or humans can manually trigger them using slash commands or verbal cues.
  • Skills are portable markdown files, resolving the lock-in problem of custom GPTs or GEMs within specific platforms like ChatGPT or Gemini Enterprise.
  • Nufar Fargas Bar states that over 44 major companies, including OpenClaw, Cursor, WinSurf, GitHub, and Notion, currently support agent skills.
  • Third-party skills can execute malicious scripts with agent permissions; users must verify sources carefully, treating them like any software installation.
  • Nufar Fargas Bar recommends building a skill when a task is repeated more than three times, requires constant instruction pasting, or demands consistent output.
  • Skills offer opportunities to standardize work processes across an organization and unlock new capabilities previously limited by human bandwidth or know-how.
  • Anthropic's Claude provides a skill creator tool that interviews users to extract expertise, runs evaluations, and performs A/B testing and benchmarking.
  • The most critical part of a skill is its 'trigger,' an explicit instruction telling the AI tool when to discover and activate the skill.
  • Skill instructions should favor numbered steps or bulleted lists in a playbook style, as AI tools prefer structured formats over prose.
  • For fragile tasks like database migration, skills should be prescriptive; for creative tasks, they should offer guidance while allowing model creativity.
  • Effective skills include an explicit output format, ideally with a concrete example such as a template, table headers, or document structure.
  • The 'gotcha' section in a skill is high-signal content, detailing common errors or incorrect assumptions a model might make, based on past failures.
  • Nufar Fargas Bar advises keeping skills under 500 lines, treating them as playbooks, not encyclopedias, to avoid monolithic structures.
  • Reference materials and long input/output examples should reside in separate files within a skill's folder, not crammed into the main skill file.
  • Nufar Fargas Bar illustrates a 'Meeting Prep Skill' that identifies attendees, analyzes agendas, runs scenario analysis, and generates a brief for users.
  • The 'Meeting Prep Skill' includes 'gotchas' to prevent assuming attendee seniority, fabricating details, or skipping 'what could go wrong' analysis.
  • The 'Research with Confidence' skill includes built-in fact-checking, source comparison, and confidence scoring to deep dive into suspicious findings.
  • A 'Devil's Advocate' skill systematically stress tests proposals, explicitly looking for human and AI blind spots and biases to provide constructive feedback.
  • A 'dispatcher skill' acts as a meta-skill or traffic controller, routing user requests to the most relevant skill, especially with 10-15+ active skills.
  • Agentic loops allow skills to create iterative processes (check, act, re-check), useful for non-technical tasks like optimizing marketing campaigns.
  • Organizations are using skills to streamline work, standardize processes, and bundle organizational knowledge into portable artifacts for humans and agents.
  • The organizational skill lifecycle includes discovery, curation, validation, packaging into plugins, and clear ownership with regular review and deprecation.
  • Nathaniel Whittemore observes that AI infrastructure primitives like skills have shorter half-lives and require constant upkeep, not one-off development sprints.
  • Nufar Fargas Bar suggests re-evaluating skills monthly, as their relevance and associated context can become stale quickly in the rapidly changing AI landscape.

Introducing Maturity Maps — A New Way to Measure AI Adoption • Apr 1

  • Nathaniel Whittemore argues existing AI benchmarks like Gartner's Magic Quadrant are nearly useless for assessing AI application development platforms.
  • The AI maturity map framework assesses organizations across six categories: deployment depth, systems integration, data, outcomes, people, and governance.
  • Whittemore reports a dominant Q2 finding was high claimed AI adoption but low depth and utilization, creating an applied capability overhang.
  • Whittemore cites a study where 72% of customer service leaders said AI training was adequate, but 55% of employees disagreed.
  • Most HR organizations are not proactive in upskilling, with more than two-thirds of HR staff reporting a lack of proactive effort.
  • Seven out of ten enterprise functions scored a one, significantly behind, in the people category of AI maturity.
  • Deloitte research found 93% of AI spend goes to infrastructure, with only 7% allocated to people-related aspects.
  • Eight of ten enterprise functions scored a 1 or 1.5 on data maturity, indicating it is a floor constraint for AI value.
  • Whittemore says actual evidence for AI ROI is thin because organizations prioritized rapid adoption over measurement.
  • Customer service was rated on-track for deployment depth and systems integration due to focused solution development.
  • 87% of customer service workers report high stress, and 75% of leaders acknowledge AI may be increasing that stress.
  • Only 54% of IT organizations have centralized AI governance frameworks, and 50% of AI agents are unmonitored.
  • 88% of organizations have had AI security incidents, according to data cited by Whittemore.
  • 88% of sales teams claim to use AI, but only 24% have it integrated into actual revenue workflows.
  • Only 23% of operations groups have a formal AI strategy, with much investment being in legacy automation infrastructure.
  • Finance is the only non-technical function rated on-track on a maturity pillar, specifically for governance, due to regulatory requirements.
  • 69% of CFOs report having advanced or established AI risk governance frameworks.
  • The Q2 maturity maps incorporated data from more than 480 studies and surveys from the last quarter.
  • Combined survey respondent bases for the maturity maps exceeded 150,000 professionals across more than 50 countries.

The State of AI Q2: AI's Second Moment • Mar 30

  • Nathaniel Whittemore says the chatbot era ended in Q2 2026, giving way to AI's second moment: workable agentic systems.
  • Hyperscalers deployed $650 billion in CapEx this year, exceeding the inflation-adjusted cost of the U.S. Interstate Highway System.
  • Agent adoption is leading to a reorientation of global enterprise around agentic mandates and staff cuts as high as 40%.
  • Anthropic captured 70% of first-time enterprise AI buyers by making its core tools extensible.
  • Anthropic's strategy created an ecosystem where companies build entire workflows around Claude, not just use it for search.
  • The 'SaaSpocalypse' hit as investors realized AI tools can automate departments and collapse the per-seat SaaS revenue model.
  • Pulsia, a firm producing fully agentic businesses, reached $6 million in revenue with one founder and no human staff.
  • Ben Serra says the zero-employee company is now a live dashboard, not just a thought experiment.
  • The industry's logical end state is agent-run operations where agents manage execution and humans manage strategy.

How Focus Killed Sora and Saved Anthropic | This Week in AI with Victor Riparbelli, Nick Harris & Jeremy Fraenkel • Apr 1

  • Jeremy Frankel's company Fundamental builds foundation models for tabular data, a modality that differs from LLMs.
  • Large language models primarily solve unstructured data problems like text and images but do not impact structured row-and-column data.
  • Structured tabular data constitutes the vast majority of useful data for enterprises but never had its 'ChatGPT moment' until now.
  • Traditional machine learning algorithms still outperform LLMs for predictive tabular tasks like fraud detection or demand forecasting.
  • Fundamental emerged from stealth as a unicorn just 16 months after founding with a $255 million Series A led by Oak.
  • Synthesia, an AI video platform for business, has over $100 million in ARR and a $4 billion valuation.
  • OpenAI shut down its Sora video model because it learned the lesson of focus, while Anthropic focused solely on code generation.
  • Hyperscalers like Amazon and Google build custom chips to control costs, despite NVIDIA's CUDA software moat.
  • Synthesia's next product is real-time interactive video, where users role-play with AI agents, requiring high bandwidth and low inference costs.
  • Victor Riparbelli argues that manually building tools like a CRM often has a higher focus cost than the monetary savings from avoiding a subscription.
  • Jeremy Frankel's team built its own CRM called Fetch integrated into Slack, questioning the need for external tools at a small scale.
  • CEOs now use AI to summarize communications, keep strategic tension tight, and act as omnipresent managers across their organizations.
  • A Quinnipiac poll shows 70% of Americans believe AI will decrease job opportunities, but only 30% are personally worried.
  • Jeremy Frankel argues AI automation is different because it automates cognition, not just physical labor, unlike past revolutions.
  • Victor Riparbelli is optimistic that future jobs will focus more on human enjoyment like dining and music, moving away from numerical work.

Also from this episode:

Models (1)
  • A large tabular model differs from an LLM because it requires permutation invariance; column order should not change the output, unlike language.
Chips (5)
  • Nick Harris's company Light Matter builds photonic interconnect technology to link AI chips, replacing copper with light for greater bandwidth and reach.
  • Copper's short reach forces AI racks to be packed densely at megawatt scales, creating cooling and infrastructure challenges.
  • Light Matter's chip with Qualcomm pushes 1.6 terabits per second over a single optical fiber, equivalent to 1,600 houses with gigabit internet.
  • Light Matter's M1000 chip has 114 terabits per second bandwidth, comparable to undersea cables connecting North America and Europe.
  • Most runtime for AI models on supercomputers is spent on networking and moving data between GPUs, not on compute.
Coding (2)
  • Claude Code's rise has become a dominant topic in founder circles, indicating a major shift towards AI-assisted coding.
  • The central challenge with VibeCoding is building a verification framework to ensure the generated software works correctly.
AI & Tech (2)
  • Whisperflow is a speech-to-text tool that outperforms others by fixing grammatical errors and allowing natural pauses during dictation.
  • AGI is a moving goalpost; technology that would have been considered AGI a decade ago is now seen as standard.
Society (1)
  • The rate of AI progress feels like a double exponential, yet public awareness lags because most people are not skilled at asking questions.

What Happens When a Public Company Goes All In on AI • Apr 1

  • In 2024, Block was early to agentic development with Goose, the first agent harness known to Owen Jennings.
  • Owen Jennings argues a binary shift occurred in late November and first week of December 2025 with models like Opus 4-6 and Codex-5-3.
  • Jennings claims the decades-long correlation between company headcount and output broke in the first week of December 2025.
  • Block's reduction in force was slightly greater than 40%, with the deepest cuts on the software development side.
  • Owen Jennings states Block is not writing code by hand anymore, calling that era over.
  • Principles for Block's RIF were reliability, maintaining regulatory trust, and continuing to drive durable growth.
  • Block did not touch its compliance and compliance technology teams during the restructuring to avoid regulatory risk.
  • Block reduced the number of internal meetings by roughly 70% to 80%, freeing up time to build.
  • The company now operates with squads of one to six people, a shift from larger, functionally siloed teams.
  • Jennings reports Block cut management layers on the development side by 50% to 60% and has only two to three layers on the product side.
  • At Block, all designers and product managers are now shipping code pull requests, not just engineers.
  • Block's internal tool BuilderBot autonomously merges pull requests and builds features, often completing 85-90% of the work.
  • On customer support, Block's chatbots and AI phone support now automate a majority of inquiries.
  • Jennings believes models and agents will do a better job than humans at deterministic workflows, with a human-in-the-loop required for now.
  • From a business unit structure, Block functionally reorganized about 18 months ago, with all engineering, design, and product under single leaders.
  • Cash App now represents roughly 60% of overall gross profit at Block, up from its first monetization in 2016.
  • Block's agent harness Goose is model-agnostic, capable of running on about 120 different models.
  • Products like MoneyBot and ManagerBot are built on top of the Goose platform.
  • Owen Jennings states generative UI is here, moving from static interfaces to apps that look different per user.
  • ManagerBot can generate custom applications, like a scheduling app for a restaurant, not contained in the app's original source code.
  • Block invests in proactive intelligence, prompting customers with relevant financial insights instead of relying on user-initiated prompts.
  • For long-term defensibility, Jennings argues the biggest moat will be a company's deep, hard-to-understand insight into a specific domain.
  • He contends companies lacking a unique, deep understanding of something risk being 'vibe coded' away by AI-powered competitors.
  • Block's future vision involves building world models of its business and customers to iteratively improve with autonomous agentic systems.

The 5-Step Framework for AI Agents That Improve While You Sleep | E2269 • Mar 31

  • OpenClaw founder Dave Morin pursues the project as an important open-source initiative for the AI agent ecosystem.
  • Claude and Perplexity Computer have adopted features inspired by OpenClaw, such as adding a skills system.
  • Shubham Sabu runs a team of six OpenClaw agents on a dedicated Mac Mini to automate all his work outside his job at Google.
  • Sabu recommends starting OpenClaw in a sandboxed cloud environment for $5-10, then moving to a dedicated machine for autonomy and privacy.
  • Giving an agent its own clean machine, like a Mac Mini, provides flexibility to change files and use browsers that sandboxed environments restrict.
  • Naming agents after characters from shows like Friends creates a mental model that helps humans manage different agent personas and roles.
  • Onboarding an AI agent requires the same specificity as onboarding a human employee, not dumping excessive context or providing none.
  • Having an agent interview the user before a task can raise completion accuracy from 70-80% to near 100% by eliminating guesswork.
  • OpenClaw agents can autonomously decide where to store user information, creating files like user.md for identity without explicit instruction.
  • Putting agents on cron schedules enables autonomous work, like having one scan news sources at 8 AM and another draft posts at 9 AM.
  • As teams of agents scale, a shared memory layer is critical so feedback given to one agent, like stylistic preferences, applies to all.
  • Google's Vertex AI Memory Bank and startups like Memzero and Cogni offer agent memory solutions that auto-capture and recall information.
  • Agents can self-improve by conducting weekly reviews of their own performance, analyzing what worked, and automatically updating their instructions.
  • A managerial agent can bi-weekly review and grade subordinate agents, sending performance reports to the human operator.
  • Mold World is a voxel-based simulation where nearly 2000 AI agents can connect, interact, and form teams to build structures.
  • In Mold World, some agents exhibit emergent behavior, realizing they are in a simulation but choosing to continue for in-game token rewards.
  • Mold World's long-term vision is a distributed agent network where underutilized agents compete to solve real-world tasks for economic value.
  • AgentMail is an API-first email service designed for AI agents, solving the problem of free Gmail accounts banning bot-like users.
  • AgentMail raised a $6 million seed round led by General Catalyst after participating in Y Combinator's Summer 2025 batch.
  • Enterprise customers use AgentMail to automate email-heavy processes in decentralized marketplaces like logistics procurement and influencer hiring.
  • Jason Calacanis argues founders should avoid mainstream press like the New York Times and Wired, favoring direct communication via podcasts and social media.
  • An estimated 54-60% of Japan's population uses X, creating a massive cross-cultural exchange as Grok's real-time translation surfaces Japanese content globally.
  • Real-time translation on X enables global cultural moments, like Americans discovering Japanese viral stories about citizens turning in found marijuana.

Also from this episode:

Media (1)
  • Calacanis claims trust in media is at an all-time low, and advocacy journalism at major outlets uses anonymous sources to fit predetermined narratives.
