Parallel Web Systems, an artificial intelligence search infrastructure startup founded by former Twitter CEO Parag Agrawal, has secured 100 million dollars in fresh funding. The Series A round values the young company at 740 million dollars and underlines how central high quality web data has become in the race to build powerful AI agents.
The company is building a new layer of infrastructure that helps AI systems access, understand and use live web information in real time. Instead of traditional search results that are designed for human users, Parallel returns structured outputs ready for direct use inside AI models. This is intended to improve accuracy, reduce hallucinations and lower costs for enterprise customers that rely heavily on AI agents.
Background: From Social Media Leadership To AI Infrastructure
Parag Agrawal became widely known as the CEO of Twitter, where he oversaw one of the world’s most influential social media platforms. After leaving that role, he shifted his focus to building foundational tools for the next generation of artificial intelligence.
Parallel Web Systems grew out of a simple observation. Modern AI agents, from coding assistants to business analysis tools, are increasingly acting as the primary users of the internet. Instead of humans manually typing queries into search engines, software agents now need structured access to fresh, reliable web information in order to complete complex tasks.
According to Agrawal, most existing solutions are still shaped around human facing search, which is not always ideal for machine consumption. Parallel aims to fill that gap by offering APIs and infrastructure specifically designed for AI systems.

Details Of The 100 Million Dollar Series A Round
Parallel’s Series A round totals 100 million dollars and places the company’s valuation at 740 million dollars. The round is co led by leading venture capital firms Kleiner Perkins and Index Ventures, both of which have long track records of backing high growth technology companies.
Existing investor Khosla Ventures and other backers also participated in the round, signaling continued confidence in Parallel’s vision and early traction. The company had previously raised 30 million dollars in January 2024, giving it a solid capital base even before this latest infusion.
With this new funding, Parallel now has significant resources to accelerate hiring, expand engineering capacity, and scale its infrastructure to serve more enterprise customers.
What Parallel Web Systems Builds For AI Agents
Parallel’s core offering is a set of application programming interfaces that allow AI agents to search the live web and bring back the information they need in a machine ready format. Rather than returning a ranked list of links for humans to click, Parallel’s system returns optimized content units, referred to as tokens, that feed directly into an AI model’s context window.
This design has several goals:
- Provide AI agents with fresh, relevant, structured information
- Reduce the amount of noisy or irrelevant data pulled into models
- Cut down on hallucinations and factual errors generated by AI systems
- Lower the operational costs associated with running AI agents at scale
Enterprise customers are already using Parallel for several high impact tasks. Examples include:
- AI coding assistants that need real time documentation and code examples from the web
- Sales intelligence tools that scan public sources alongside internal data to generate insights for sales teams
- Insurance underwriters that rely on external information to refine risk models and assess emerging threats
In all these cases, Parallel sits between the open web and the AI model, ensuring that the agent receives curated, high quality data in a form it can use efficiently.
Why AI Focused Web Search Infrastructure Matters
Agrawal has framed the problem with a simple question. If most human jobs would be impossible without web access, why would we expect AI agents to operate effectively without it. Just as lawyers, analysts and engineers rely on the internet as a core tool, their AI counterparts need direct access to online information in order to perform at a high level.
Traditional search engines are tuned for human interfaces, with snippets, ads and complex layouts that do not translate neatly into the context window of a large language model. Parallel is betting that a dedicated infrastructure layer for AI first search is needed as AI adoption spreads into more industries.
By focusing on accurate, structured and cost effective data delivery, the company hopes to become a critical utility for organisations deploying AI agents in production.
Tackling The Challenge Of Paywalled And Restricted Content
One of the biggest challenges facing AI companies is the growing amount of content locked behind paywalls or restricted by login requirements. Many publishers, platforms and social networks are tightening control over their data as they see traffic patterns change and seek to protect their business models from unlicensed scraping.
Parallel plans to use part of its new funding to work on this issue directly. Agrawal has spoken about creating an open market mechanism that would allow AI companies and content owners to collaborate rather than conflict. The basic idea is to design a new economic model that rewards publishers for making high quality content accessible to AI systems under clear and transparent terms.
While detailed plans have not yet been made public, the concept suggests a future where publishers could be compensated when their content is used to power AI agents, instead of simply being scraped without permission.
Use Of Funds And Future Roadmap
Agrawal has said that the new capital will allow Parallel to go all in on both product development and customer growth. Key priorities include:
- Expanding engineering teams to refine and scale the search infrastructure
- Building new APIs and features tailored to specific industries, such as finance, legal or healthcare
- Strengthening partnerships with enterprises deploying AI agents in mission critical roles
- Exploring commercial arrangements with publishers and platforms around data access
Founded two years ago, Parallel launched its first products in August 2025. The company is still in the early stages of its journey, but the size and quality of the Series A round signal that investors see a substantial long term opportunity in AI native search infrastructure.
