Your Questions Answered: Vibe Coding, Consumer Defensibility, and the Future of Agent Management

Welcome to a special mailbag episode of Generative Now! Michael Mignano, partner at Lightspeed, takes on questions submitted by listeners through X and LinkedIn.

Rather than preparing responses in advance, Michael will be tackling these questions live on the podcast with producer Danielle reading them aloud. This format creates a spontaneous conversation focused on addressing listener curiosities about AI markets, opportunities, and emerging roles.

Michael addresses whether the app layer will see more opportunities in new markets or existing markets. His answer? Both, with existing markets likely seeing the larger immediate impact.

In existing markets, AI will drive greater efficiency, leading to higher margins that companies can reinvest into growth. Meanwhile, new markets will emerge as AI enables previously impossible capabilities, though predicting exactly what those will be remains challenging.

When pressed to choose one area with greater opportunity, Michael leans toward existing markets while acknowledging that software consistently surprises us with unanticipated new market applications.

Michael cautions that we may be trying too hard to predict exactly which AI applications will be transformative, as the most impactful innovations often come as a surprise.

Will SaaS total addressable markets (TAMs) expand 10x with AI agents or decline due to commoditization from tools like vibe coding? Michael takes an optimistic view on market expansion.

Michael draws parallels to how the internet has consistently demonstrated that increased supply of products and services leads to increased consumption rather than market saturation. He believes AI-powered development tools will enable software to address previously unfilled needs and create entirely new product categories.

The result, according to Michael, will be market expansion not just in SaaS but also in consumer sectors, as AI enables the creation of significantly more software addressing a broader range of use cases.

Michael addresses a critical question from LinkedIn about how consumer AI startups can create genuine defensibility beyond first-mover advantage or superior UX.

Despite the fundamental principles remaining the same, Michael points out that the risk landscape has changed significantly. The democratization of software development through AI means startups now face potentially hundreds or thousands of competitors rather than just a few.

This intensified competition raises the bar for quality and execution speed. First movers must rapidly establish network effects and data flywheels before competitors can gain traction.

This democratization of development capabilities means consumer AI startups must focus even more intently on building strong moats through network effects, proprietary data, and compelling brands while moving faster than ever before.

Michael explores two emerging roles in AI companies: Agent Engineers and Agent Managers. While acknowledging he's not an expert on the specific job postings mentioned, he offers valuable insights into how these roles differ and what they might evolve into.

For Agent Engineers, Michael sees them as a new breed of software engineers with unique characteristics:

The role requires adaptability and comfort with handing significant control to AI systems, without being precious about traditional software engineering paradigms.

In contrast, Agent Managers represent something more revolutionary:

Michael highlights how managing AI agents differs fundamentally from managing human teams:

This complexity creates opportunities for entirely new tools, workflows, and perhaps even markets focused on agent management, monitoring, and optimization.

While Agent Engineers represent an evolution of existing roles, Agent Managers point to an entirely new workflow for orchestrating and supervising potentially millions of non-human agents performing tasks across organizations.

• AI will drive significant opportunities in both existing markets (through efficiency gains) and new markets (through previously impossible capabilities).
• Existing markets will likely see the bulk of immediate opportunity, though the most transformative applications often come as surprises.
• SaaS TAMs will expand rather than contract as AI enables software to address previously unserved needs and create new product categories.
• Consumer AI startups still need traditional moats like network effects, data advantages, and strong brands - but must build them faster due to increased competition.
• The democratization of software development through AI means startups now face potentially thousands of competitors rather than just a few.
• Agent Engineers represent an evolution of software engineers who need prompt engineering skills, vector database knowledge, and greater adaptability.
• Agent Managers represent an entirely new workflow for orchestrating AI agents, creating opportunities for new tools and services focused on monitoring and optimizing agent performance.
• Managing AI agents is fundamentally different from managing humans due to the challenge of understanding what thousands or millions of agents are doing at scale.

Michael explores the most promising verticals for consumer AI applications, highlighting several key areas where he sees significant opportunity.

Consumer services emerge as a major focus area, where AI can deliver greater efficiency and lower costs for everyday needs:

Education stands out as another massive opportunity that Michael is personally invested in:

He emphasizes how AI can function as a personalized tutor that knows not just the subject matter, but also how each individual learns best:

Michael also highlights the emerging "vibe coding" space - the democratization of software development through AI - as creating two major opportunities:

1. A market for tools and services catering to new creators
2. An explosion of novel consumer applications built by these creators

He specifically mentions gaming as an area seeing rapid innovation due to reduced barriers to entry:

Michael concludes by acknowledging that as with any transformative technology, consumer AI will likely produce surprising innovations that nobody currently anticipates.

Michael addresses what acquisition could help Apple overcome its perceived lag in AI development, suggesting that only acquiring a leading foundation model company would truly move the needle.

He acknowledges the enormous challenges such an acquisition would face, both in terms of regulatory approval and unprecedented cost, but suggests the strategic value might justify such a bold move:

The core value of such an acquisition would be gaining capabilities beyond what Apple's Siri currently offers, enabling AI that can truly act on behalf of users within the iOS ecosystem:

Michael also explores an alternative strategy - acquiring a company like Replit that could accelerate app development for the App Store. However, he distinguishes this from solving Apple's core AI assistant problems.

Given Apple's historically conservative approach to acquisitions, Michael notes that this situation might warrant an unprecedented move:

Michael explores an interesting question about AI's potential role in dispute resolution and arbitration, a topic he admits he hadn't previously considered in depth.

He identifies AI's potential impartiality as a key advantage in legal contexts where emotional factors can complicate outcomes. This connects to his earlier point about consumer services, suggesting legal services as a particularly promising area for AI to improve efficiency and reduce costs:

Michael also explores how blockchain-based platforms like Polymarket, which document real-world events on a public ledger, might intersect with AI-powered dispute resolution:

He envisions a potential hybrid system that combines AI's analytical capabilities with human verification, all documented transparently on a public ledger:

Though thinking through this application in real-time during the podcast, Michael sees genuine potential for AI to transform dispute resolution and arbitration processes.

Timestamp: [13:19-14:37]

Michael addresses a question about the current state of venture capital in AI, including LP deployment, check sizes, and capital calls. He emphasizes the overwhelming investor interest in the space despite recent market volatility.

This enthusiasm spans the entire investment ecosystem, from limited partners (LPs) and general partners (GPs) to founders, all recognizing AI as a transformative opportunity:

Michael notes that the key question for investors is where to place their bets across the AI landscape:

Despite recent market turbulence, Michael observes that investor appetite for AI remains strong:

Michael closes by sharing his personal excitement about consumer AI, particularly how the creative capabilities are now catching up to the technology:
