About Linkup
Our Vision
We believe in a future of AI agents and the agentic web. These digital entities can create more value for humanity than we ever could alone, but they depend on the internet to operate, collaborate, take action, and gather information.
AI agents need web search. To perform well, they require information that is current, reliable, and context‑specific—not the diffuse, steadily aging knowledge frozen at their last training cut‑off.
Modern web search is built for humans, not AIs. Instead of trusted facts, it serves links, ads, and click‑bait. People want visually engaging pages; AI systems need structured truth. An AI can absorb oceans of data, while human attention barely skims the surface. Humans think visually and intuitively; AI reasons in latent space.
Web 2.0 is sunsetting. The deck is being reshuffled, and the Bing‑Google search oligopoly is crumbling. Indexing ever more pages is no longer the goal; semantically organizing facts for AI systems is. In the coming agentic web, Google’s ad‑driven model has no natural home.
Search for AI must be rebuilt from the ground up. We are reconstructing the web as a rigorously structured knowledge layer, mapping every concept, entity, and claim into a coherent semantic graph. This foundation delivers verified facts and rich context to AI instantly, unlocking faster reasoning, higher accuracy, and radically more useful answers for everyone.
Humans search Google; AI searches Linkup.
Our Mission
Reality never stands still, and neither should intelligence. Linkup reconnects language models to a living stream of verified facts, ensuring AIs remain as current and insightful as the world they serve.
Our mission is to deliver the world’s freshest, most trusted knowledge to AIs.
Our Culture
Our culture is built on the following values:
Mission. We believe we play a critical role in building the agentic web. We are 100% committed to our mission of bringing the reality of the world to AI agents.
Speed. We build fast, we build to last. We get things done, well.
Ownership. We empower every team member to take ownership of their projects, ensuring they see them through to successful completion.
Teamwork. Our strength lies in our unity. We rely on one another and embrace our diversity as a core asset.
Humility. We maintain low egos, showing respect for others and continuously learning from their insights and experiences.
We expect all team member to take an active role in shaping our company culture.
Our Team
We are small technical team, working shoulder to shoulder to build the web of agents.
A bit more about our 3 co-founders:
Philippe Mizrahi- Led the development of Lyft’s Autonomous Vehicles marketplace. Previously launched Amundsen, an open source search engine.
Denis Charrier- Founding Engineer at Niland, an audio search company (acquired by Spotify), then Staff Engineer at Spotify. 15y of software development experience.
Boris Toledano- Led robotics at Carrefour, after 3y at McKinsey & Co working on public affairs and digital transformation.

Founding GTM Engineer
About the Role
We’re hiring Linkup’s first GTM Engineer — a technical builder who will architect the systems powering how we grow, learn, and engage with users.
This role sits at the intersection of data, automation, and go-to-market strategy. You’ll build the connective tissue between our external growth (outbound, inbound, marketing) and internal success (sales, product, and forward-deployed engineering).
You’ll automate how we find, qualify, and reach new users; identify how Linkup delivers value to users; and ensure those learnings flow back into our marketing, sales, and product loops.
It’s a high-impact, high-ownership role — you’ll work directly with the founders to define how Linkup scales.
What You’ll Do
Build scalable growth systems — from outbound automation to usage-based lead scoring and CRM enrichment.
Design and maintain integrations across our GTM stack (Attio, Slack, Notion, LinkedIn, internal APIs, etc.).
Feed qualified leads to the sales and forward-deployed teams through automated workflows and analytics.
Build automation that captures and structures signals from new users to drive conversion and engagement and support product specialists.
Build systems that support retention, expansion and customer-success outreach (e.g., detecting churn risk, triggering re-engagement)
Why This Role Matters
This is the first GTM engineering role at Linkup — the bridge between our growth engine and our product.
You’ll connect the dots between who discovers Linkup, how they use it, and what makes them successful.
By automating our growth stack and uncovering patterns in user behavior, you’ll give our sales, marketing, and forward-deployed teams the leverage they need to scale impact.
If you love blending code, data, and storytelling to drive growth, this role was made for you.
You’re a Great Fit If You
Have 2 years+ relevant experience, ideally in fast-growing technology/SaaS company.
Hands-on with modern GTM stacks (CRM, APIs, enrichment tools, workflow automation).
Comfortable with Python, SQL, and API integrations — bonus for experience with LLM or search APIs.
Demonstrated ability to turn messy data and processes into scalable systems that drive pipeline or adoption.
Want to work with important ownership in a high intensity, fast moving environment.
Are excited to help build Google for AI agents and believe in Linkup’s mission.
Example Projects
Build an autonomous outbound sequence combining LinkedIn, email, and product usage signals.
Design a pipeline that analyzes prospect queries and crafts personalized reach-outs.
Use our internal web index to identify similar companies to top users — and contact them automatically.
Connect CRM and product data to prioritize high-intent accounts in real time.
Run experiments to uncover the highest-performing messaging, timing, and channels.
Create inbound automation to surface product insights for forward-deployed teams.

About Linkup
Our Vision
We believe in a future of AI agents and the agentic web. These digital entities can create more value for humanity than we ever could alone, but they depend on the internet to operate, collaborate, take action, and gather information.
AI agents need web search. To perform well, they require information that is current, reliable, and context‑specific—not the diffuse, steadily aging knowledge frozen at their last training cut‑off.
Modern web search is built for humans, not AIs. Instead of trusted facts, it serves links, ads, and click‑bait. People want visually engaging pages; AI systems need structured truth. An AI can absorb oceans of data, while human attention barely skims the surface. Humans think visually and intuitively; AI reasons in latent space.
Web 2.0 is sunsetting. The deck is being reshuffled, and the Bing‑Google search oligopoly is crumbling. Indexing ever more pages is no longer the goal; semantically organizing facts for AI systems is. In the coming agentic web, Google’s ad‑driven model has no natural home.
Search for AI must be rebuilt from the ground up. We are reconstructing the web as a rigorously structured knowledge layer, mapping every concept, entity, and claim into a coherent semantic graph. This foundation delivers verified facts and rich context to AI instantly, unlocking faster reasoning, higher accuracy, and radically more useful answers for everyone.

Founding Forward Deployed Engineer
About the Role
We’re looking for a top-tier Forward Deployed Engineer to join Linkup and work hand-in-hand with our founders, customers, and partners. This is our first hire at this role.
Your mission: help leading AI companies, developers, and enterprises integrate Linkup’s AI-ready search APIs into their products — and shape how the next generation of AI agents connects to the web.
This is a highly cross-functional role. You’ll operate at the intersection of engineering, GTM, and customer success, turning technical integrations into insights that drive our product roadmap, marketing narratives, and outbound strategy.
You’ll be the connective bridge between what customers build with Linkup and how we tell that story to the world.
What You’ll Do
Work directly with customers and partners to design, prototype, and deploy integrations of Linkup’s APIs into real-world agentic systems.
Participate in pre-sales efforts — technical discovery, proof-of-concept design, demo environments.
Collaborate cross-functionally with backend, ML, and product teams to ensure performance and reliability at scale.
Partner with the GTM Engineer and DevRel team to turn customer learnings into automation, tutorials, and playbooks.
Identify and implement technical integrations with our other partners ****in the value chain (workflow orchestration, AI frameworks, etc.)
Translate complex technical concepts into clear explanations for both developers and business audiences.
Why This Role Matters
Every integration you build helps define how AI systems connect to live, trusted information.
You’ll operate on the frontier between customers and product — bringing the voice of the field into everything we build and say.
Your work will inform:
The stories we tell in marketing.
The use cases we automate in our GTM systems.
The features we prioritize in our roadmap.
If you love blending engineering with impact — building things users actually depend on — this role is for you.
You’re a Great Fit If You
4+ years in technical support engineering, software engineering, or solutions engineering, with direct application development experience.
Strong API integration skills — able to design and debug REST/JSON payloads, manage auth flows, and optimize latency.
Understand web infrastructure, distributed systems, or retrieval pipelines.
Are comfortable debugging integrations and solving ambiguous technical challenges in customer environments.
Communicate clearly and empathetically with both technical and business audiences.
Are curious about AI infrastructure, retrieval, and the emerging agentic ecosystem.
Thrive in a fast-paced, high-ownership startup environment.
Example Projects
Help a partner integrate Linkup’s /search endpoint into their multi-agent workflow.
