Navigating Web3 tides with focused insightsBy SenseAI
Andreessen Horowitz, commonly known as a16z, is a leading U.S. venture capital firm that has invested across virtually every AI sector over the past two years. The investment strategies and insights from a16z significantly influence the tech industry. Recently, two a16z partners, Connie Chan and Justine Moore, released a report stating that just as the iPhone revolutionized how we interact with mobile devices, generative AI will transform daily life and become the foundational layer for future consumer experiences. This article analyzes potential entrepreneurial opportunities and core logic across seven domains—search, education, content creation, and more—and highlights representative products. How is generative AI changing our lives?
Sense Reflection
We attempt to offer additional speculative extensions and deeper reflections based on the article’s content—welcome to exchange thoughts.
Generative AI fundamentally resolves the conflict between scalability and personalization, enabling service industries to achieve “personalized experiences at scale” at low cost.
Search is one of the most transformative internet functions powered by large language models. AI enables personalized education and social interaction, lowers the barrier to creating text, images, UI, games, and other content forms, and vertical-specific tools help enterprises streamline workflows and improve efficiency.
We have already entered the era of generative AI, with applications everywhere—from writing articles and creating comics to editing films. Its adoption speed has surpassed every consumer tech trend of the past decade. Text-generation tool ChatGPT attracted over 1 million users in just five days, and tens of millions of users have already created AI avatars.
Whenever a new technology captures consumer attention so rapidly, a key question arises: does it truly deliver value? The authors believe the answer is yes. Generative AI will become the foundational technology for entrepreneurs building new products.
Just as the iPhone completely transformed our everyday interaction with technology—giving rise to products like Uber, DoorDash, and Airbnb—generative AI will reshape our daily lives. Beyond creating entirely new product categories, AI will also enhance existing ones, elevate user experiences, and expand use cases.
One of AI’s most powerful attributes is its ability to make products deeply personalized. Early applications are emerging in edtech and search—for instance, explaining why it rains to an eight-year-old requires a different approach than explaining it to a high school student. This kind of personalization will become a core value proposition for many AI-driven products.
Below, we explore several application areas ripe for new entrepreneurial opportunities and share key questions a16z considers when investing in such AI applications.
01.Search
Search: A core internet function with immense potential to be reinvented by large language models.
We’ve all experienced typing a query into Google only to be overwhelmed by numerous links, some offering conflicting or inaccurate information. What if you could get a concise, natural-language answer with supporting links for deeper reading? LLM-powered search engines make this possible.
Companies like You and Neeva are offering this service for general search. Others take a more vertical approach: Consensus searches research papers to provide evidence-backed answers, while Perplexity’s early Bird SQL product used Twitter feeds as its search corpus.
This type of search is highly valuable for product recommendations. When shopping online, we often need to sift through dozens of links and hundreds of reviews before making informed decisions. What if you could receive a curated list tailored to your specific needs? For example: “Best dog food for a six-month-old Labrador with a sensitive stomach” or “camel-colored winter coats under $250 in New York.”
Moreover, a16z believes enterprise internal search holds massive potential. Most companies today use multiple communication apps and databases—Gmail, Slack, Drive, Asana, etc.—making it challenging to locate a single document, message, or metric across these tools. Products like Glean enable cross-app search for teams, while Vowel allows users to query content from their video meeting recordings.
02.Education
Edtech has long faced a trade-off between efficiency and personalization. Building products for mass audiences sacrifices individual engagement; crafting perfect personalized solutions is too costly to scale.
With AI, this dilemma now has a solution. We can now deploy personalized learning plans at scale, giving each user a “teacher in their pocket” who understands their unique needs, answers questions, and administers assessments.
Imagine an AI-powered language tutor capable of real-time conversation, providing feedback on pronunciation and word choice. Indeed, companies like Speak, Quazel, and Lingostar are already delivering such experiences across nearly all academic subjects. Apps like Photomath and Mathly guide students through math problems, while PeopleAI and Historical Figures teach history by simulating chats with notable historical figures.
Beyond subject-specific learning, students are increasingly using AI assistants for homework. Tools like Grammarly, Orchard, and Lex help students overcome writer’s block and improve writing skills. Content generation tools are also gaining popularity across high schools and universities—e.g., Tome and Beautiful.ai assist in creating compelling presentations.
03.Social
a16z doesn’t believe technology will fully replace human interaction, but it can at least help reduce feelings of loneliness. Listening and responding are essential to conversation, and AI chatbots can fulfill this role.
Evidence can be found in Reddit comments about AI chatbot products like Replika, Anima, and CharacterAI. Many users report finding genuine meaning in their relationships with these bots, spending hours per week chatting. This level of consistent engagement rivals Gen Z’s Snap streaks.
AI can also augment and strengthen human relationships. Tools like Millie and YourMove optimize dating app profiles and messages, while apps like Mumkin help users navigate difficult conversations. Eventually, we may all have an AI chatbot that reminds us when to reach out to loved ones and suggests appropriate messages.
Furthermore, AI might even help us reconnect with deceased or unreachable individuals. Have you ever wished to hear a story from a lost family member again, or receive advice from someone you haven’t spoken to in years? Some have already experimented with this idea. It’s not hard to imagine a world where each of us has an AI-powered “digital twin,” trained on all our written and spoken data. For some entrepreneurs, this exploration has already begun.
04.Healthcare & Professional Services
a16z expects to see more AI chatbots entering professional and even clinical applications. AI-driven therapists, nutritionists, and coaches could benefit millions globally. These would be 24/7 support systems—users simply open an app to ask questions or start a conversation.
Early studies suggest chatbots can be effective in mental health therapy. Products like Woebot and Wysa have demonstrated clinically validated outcomes and received FDA recognition for effectiveness in treating postpartum depression, chronic pain, and anxiety. At a time when over 25% of adults suffer from diagnosable mental health conditions and there’s a nationwide therapist shortage, chatbots could offer a viable solution for non-acute cases.
Beyond healthcare, a16z is seeing AI tools and “coaches” emerge to assist with specific tasks. For example, InterAlia helps with outfit coordination, Prodigy AI offers career advice, and Poised improves communication skills.
Someday, we may all have personalized chatbots that understand the unique context of our lives. During major life transitions—divorce, college, parenthood—we’ll receive empathetic guidance. Whether pursuing fitness goals or improving financial health, we’ll be able to seek ongoing support and coaching.
05.Content Creation
Generative AI turns imagination into reality: when it works well, it feels like magic. Content creation has become the first mainstream use case for generative AI, as seen with Lensa. Remember when your social feed was flooded with friends transformed into superheroes, astronauts, and anime characters?
Portrait generation is just the beginning. Generative AI tools will serve diverse use cases—from consumers creating fun content to creators and solopreneurs monetizing their work. We’re seeing AI tools across nearly every medium:
-
Art: Products like Midjourney and Stable Diffusion let users input prompts and styles to generate AI-created artwork.
-
Writing: While tools like Sudowrite and Verb.ai cater to professional writing (e.g., fiction), ChatGPT remains the market leader.
-
Video: Descript and RunwayML are expanding from video editing to full content creation, while Linum, QuickVid, and Synthesia generate new video content.
-
Design: Canva has integrated AI, and Microsoft is testing its own AI design platform, competing with startups like PhotoRoom and Magician.
-
Audio: Boomy and Riffusion compose music from scratch, while Murf.ai and Resemble deliver studio-quality voiceovers.
Over time, we’re likely to see more professional-grade generative AI tools emerge.
Many current AI tools still have flaws—such as generating images with three arms—or require long processing times. This is acceptable for casual entertainment, but problematic for monetization. To meet advanced users’ demands, a16z expects many companies to launch “pro” versions offering higher quality, similar to what ChatGPT already offers.
06.Gaming
AI is poised to play a major role in gaming—a topic a16z partners have extensively discussed. Generative AI will make creating high-quality games easier, faster, and cheaper, while allowing players to truly customize their experiences.
Popular games often cost millions or even billions of dollars to produce. Beyond the storyline, developers must create thousands of media assets—from graphics and 3D models to soundtracks.
The vitality of these AAA games comes from the labor and vision of human artists. While AI is unlikely to fully replace them, a16z believes AI will empower these creators and their teams, helping them use time more efficiently, launch games faster, and reduce costs.
We’re already seeing AI tools like Scenario and Iliad generating game assets, platforms like Promethean building entire virtual worlds, and products like Inworld, Charisma, and Convai creating non-player characters (NPCs).
AI won’t just accelerate game development—it will enable entirely new genres: more dynamic, adaptive, and personalized to individual player preferences. We’re already seeing early prototypes in text-based games like AI Dungeon and Hidden Door. Imagine entering a game and designing a complex custom avatar with just a few sentences. Ultimately, this could extend to creating entire virtual worlds from scratch.
07.Enterprise Services
Tools serving small businesses represent a killer application for generative AI. There are 32 million small businesses in the U.S., responsible for over half of net new jobs since 2000. These businesses are vital to the economy but often understaffed and overwhelmed—especially amid recent labor shortages.
AI tools can make an immediate impact by acting as an extra pair of hands. Though not always perfectly reliable, they’re still incredibly valuable. Use cases and tools continue to grow: Sameday answers calls and schedules appointments; Truelark handles texts, emails, and chats; Osome manages back-office operations; and Durable builds complete professional websites.
General content creation tools like Jasper, Copy, and Writer have already gained significant traction among SMBs. a16z is also seeing vertical-specific tools tailored to particular business workflows. For example, Harvey and Spellbook help legal teams automate intake, research, and document drafting. In real estate, Interior AI enables agents to virtually stage properties, while Zuma helps property managers convert leads into scheduled tours.
Among these, e-commerce has been the most fertile vertical. Most e-commerce businesses operate fully online, making it easy to integrate AI tools across workflows. In a world of rising customer acquisition costs, brands are eager to try tools that reduce expenses, boost conversion rates, and improve retention.
Flair, Booth, and Bloom help brands create compelling product images—critical for selling to online shoppers. A static photo of a dress on a hanger can become an image of a woman walking through a garden wearing it. a16z expects these applications to become hyper-personalized: a photo of a sofa could generate an image of it placed in your living room.
Beyond product images, many types of brand content can now be enhanced via AI. Tools like AdCreative and Pencil generate marketing materials for email or social media, while Frase or Writesonic write SEO-optimized product descriptions. Eventually, users may simply describe their desired aesthetic, click a button, and instantly generate a complete e-commerce store with all marketing assets.
