Former Twitter CEO Fired by Elon Musk Raises Another $100 Million: Building Dedicated Search Engine for AI Agent

According to Data Beating monitoring, Parallel Web Systems, founded by former Twitter CEO Parag Agrawal, has completed a $100 million Series B financing round led by Sequoia Capital, with a valuation of $2 billion. Kleiner Perkins, Index Ventures, and Khosla Ventures also participated in the investment. The company had just completed a $100 million Series A round (valued at $740 million) in November last year. Within six months, the valuation has nearly tripled, with a total funding of $230 million.

Parallel's focus is to build dedicated web search infrastructure for AI agents. Agrawal's vision for 2023 is that agents will use the web far more frequently than humans in the future, requiring an access layer independent of the browser. Typical use cases include investment research, insurance claims, and government contract retrieval for "deep research" tasks that humans can also perform, but agents can do faster and at a larger scale.

Sequoia partner Andrew Reed has joined the board, linking Parallel's growth directly to the rapid development of "long-cycle agents" (agents capable of autonomously running in the background and maintaining context for extended periods), with web search being a core shared capability of such agents. AI law firm Harvey is one of Parallel's clients, with co-founder Gabe Pereyra stating that enabling agents to search the web is not as simple as plugging into a search engine. Harvey requires fine control over which websites the agent should access and which ones it should avoid.

Parallel currently has around 50 employees, and over 100,000 developers are using its infrastructure. Competitors in the same space include Tavily and Exa. Agrawal was ousted from Twitter at the end of 2022 due to Musk's acquisition of the company, where he previously served as Twitter's CTO.
