AI agents for specialized business tasks

We're interested in AI agents that transform internal organizational workflows, focusing on the complex, repetitive processes that currently consume significant human capital. These agents are designed to operate entirely within a company's existing systems, optimizing internal operations that are currently manual, fragmented, or inefficient. We're looking for founders who can build AI agents that integrate deeply with a company's specific software ecosystem, enabling intelligent automation that goes beyond simple task completion to even improve how its currently done.

Ready-to-go ideas :

We aim to build an AI workspace for life sciences companies to automate internal processes. Initially, it will help pharmaceutical, medical device, and biotech companies automate the creation of regulatory and compliance documents, with plans to streamline more processes over time.

Voice-first interfaces

Voice technology is approaching a tipping point where it will become a primary interface for professional work. We believe the next wave of productivity gains will come from voice-native applications that go beyond simple dictation to enable complex task completion and workflow management. We're looking for founders who understand both the technical challenges and human factors in voice interfaces, and who can create experiences that feel natural while delivering real productivity gains.

Ready-to-go ideas :

We are building a specialized voice AI that handles the first customer phone calls for service businesses. AI can now handle first-level phone conversations—answering questions, routing calls, and scheduling appointments — the solution integrates directly with systems like ERPs and CRMs, using industry-specific data to ensure high accuracy.

RecruitmentX
Matthieu Vaxelaire

At RecruitmentX, we want to reinvent recruitment by leveraging a verticalized voiced AI. Our solution enhances every interaction between recruiters and candidates, enabling recruiters to focus fully on candidates while we handle the rest.

AI-driven security & compliance

The rise of AI is creating entirely new categories of security threats and compliance challenges. Traditional security tools weren't designed for an AI-first world, creating an urgent need for new approaches. We're looking for founders who can leverage AI to protect against emerging threats while helping organizations navigate increasingly complex regulatory requirements. The opportunity is to create new frameworks for security and compliance in an age of AI. This includes everything from protecting against AI-powered attacks to ensuring AI systems themselves operate within regulatory boundaries.

Ready-to-go ideas :

CodeX is an AI-powered tool that helps developers detect security vulnerabilities in their code. Unlike other tools that can overwhelm developers with false alarms, CodeX is designed to reduce these false positives, making it reliable and efficient. Additionally, CodeX considers the context of the code to show whether a detected vulnerability is actually a real risk. This way, developers can trust the tool to highlight only the most relevant issues, making their workflow smoother and more effective.

AI agent Infrastructure

As AI agents increasingly perform autonomous actions, we need to build new infrastructure to enhance their performance. This includes systems for payments, data management, and human oversight. For example, Coinbase AI wallets will enable AI agents to pay autonomously to get through paywalls, use paid APIs, subscribe to services, etc. We are currently identifying opportunities to reduce friction for these AI agents and prepare businesses for this new era.

AIAnalyticsX
Florent Quinti

As ChatGPT and Perplexity searches gain ground over Google, brands need to track their visibility and conversion rates on these AI platforms. A new analytics category will emerge to help brands manage their digital presence and messaging in the AI era—think Google Analytics, but for AI-powered searches.

AI developer tools

The developer tool ecosystem continually reinvents itself to meet evolving needs. From PHP and C-like languages 20 years ago to JavaScript, Python, and Rust today, the landscape is always shifting. We believe LLMs will fundamentally transform the developer's role, with a greater short-term impact than on blue-collar jobs. Many tools in use today will be replaced in the coming years to align with AI and emerging languages.

Ready-to-go ideas :

We help companies ship great AI features, better and faster. Basalt allows you to prototype quickly, evaluate easily and deploy with confidence your prompts. We already have customers and an incredible CTO, we are looking for a cofounder to join us.

Vertical SaaS

By specializing in specific industries, vertical SaaS companies can address unique workflows and achieve greater market share than horizontal solutions. Advances in cloud computing, embedded finance APIs, and AI now enable vertical SaaS companies to scale efficiently and unlock new revenue streams, challenging the long-held belief that the TAM of vertical SaaS was too small.

Ready-to-go ideas :

With FranchiseX-1, we want to help Franchisors better manage and grow their Franchisees network. From opening new franchisee to growing it, we want to build the all-in-one solution for franchisors to grow. With FranchiseX-2, we want to build a digital franchise, such as Slice (Pizza), Moxie (MedSpa), etc for another vertical. It’s a vertical SaaS to help all operations in a specific merchant category.

Service-as-a-software, powered by AI

Traditional service industries have long relied on external agencies and freelancers, creating inefficient and costly workflows. We're looking for founders who can replace these external services with AI-powered tools that companies can use internally. Instead of hiring a legal agency, recruiting firm, or design service, companies will use specialized AI platforms that deliver high-quality results at a fraction of the cost. Early examples like Reki in financial services show the potential – transforming entire service categories by bringing specialized capabilities directly into organizations.

Open-source alternatives

As AI becomes more central to business operations, we're seeing growing demand for open-source alternatives to proprietary platforms. I's about control, transparency, and customization. We're looking for founders who can build robust, enterprise-grade open source solutions that give organizations more flexibility and control over their AI infrastructure. The best opportunities will be in areas where trust and transparency are particularly critical.

Prosumer AI tools

The rise of the creator economy and WhatsApp-first businesses has created a new class of prosumers who need powerful but accessible tools. We're interested in creating AI-powered solutions that help these users operate more efficiently and professionally without requiring technical expertise. The opportunity is to democratize capabilities that were previously available only to large organizations, enabling a new wave of digital entrepreneurs and creators.

Redesigned care pathways

Healthcare is facing a time crisis, with both providers and patients suffering from inefficient, outdated processes. We believe the solution isn't just to optimize existing pathways – it's to create entirely new ones. We're looking for founders, especially those with medical backgrounds, who can reimagine how care is delivered from the ground up. The opportunity is to build systems that dramatically improve both the provider and patient experience while maintaining or enhancing care quality. This goes beyond telemedicine or digital health records; we want to see fundamental reimagining of how healthcare services are structured, delivered, and experienced.
