Google does more than build products; it trains founders. Engineers, researchers, and executives who leave Google often launch startups that redefine entire markets. Venture capital firms track this “Xoogler” effect closely because former Google employees bring scale-first thinking, deep AI expertise, and strong execution discipline. In 2024 and 2025, startups founded or led by ex-Google talent continued to dominate funding rounds, talent wars, and enterprise adoption, especially in artificial intelligence.
Below is a detailed look at the most influential startups founded by former Google employees, along with the latest developments and strategic momentum.
Glean – Reinventing enterprise search with AI
Arvind Jain spent more than a decade at Google, where he helped build Search, Maps, and YouTube infrastructure. He founded Glean to fix a problem he understood deeply: employees waste hours searching across fragmented internal tools.
Glean delivers an AI-powered enterprise search and assistant that understands company context. The platform connects to Slack, Google Workspace, Jira, Confluence, and dozens of SaaS tools, then delivers precise answers instead of keyword lists. Large enterprises adopted Glean quickly because the product reduced onboarding time and improved productivity.
In late 2024, Glean raised a major growth round that pushed its valuation beyond $4 billion. The company expanded aggressively across North America and Europe and hired senior enterprise sales leaders to support Fortune 500 customers. Glean now competes directly with Microsoft and emerging AI assistant platforms, yet it maintains an edge through deep search relevance expertise rooted in Google DNA.
Character.AI – Consumer AI built by model pioneers
Noam Shazeer and Daniel de Freitas left Google after contributing to foundational transformer research. They launched Character.AI to explore conversational AI with personality, memory, and emotional tone. Users can talk with fictional characters, historical figures, or custom-created personas.
Character.AI achieved explosive consumer growth and ranked among the fastest-growing AI apps globally. In 2024, the company entered a high-profile agreement with Google that combined technology licensing and strategic collaboration. That move highlighted a broader trend: Big Tech increasingly partners with startups founded by its own alumni to regain momentum in competitive AI races.
Character.AI continues to invest in safety tooling, creator monetization, and long-form conversational memory. The company also explores subscription revenue as consumer AI demand matures.
Cohere – Private and secure LLMs for enterprises
Aidan Gomez, one of the authors behind the original transformer paper, and Nick Frosst, a former Google Brain researcher, founded Cohere to serve enterprises that demand control, privacy, and customization.
Cohere builds large language models designed for business use cases such as document summarization, customer support automation, and internal knowledge systems. Unlike consumer-first AI labs, Cohere focuses on private deployments, regional data residency, and compliance.
In 2024, Cohere expanded partnerships with cloud providers and system integrators to reach regulated industries like finance and healthcare. The company also released new multilingual and retrieval-augmented models that improved accuracy for enterprise workloads. Investors continue to view Cohere as a serious alternative to hyperscaler-owned models.
Adept – Teaching AI to take action
Adept emerged from former Google Brain researchers who wanted AI systems to do more than generate text. The team set out to build action-oriented AI agents that can operate software, complete workflows, and execute tasks across tools.
Adept’s models interpret user intent and interact with interfaces such as browsers, spreadsheets, and internal dashboards. This approach aligns with the future of “agentic AI,” where systems act as digital coworkers rather than chatbots.
During 2024, Adept drew intense interest from large technology companies eager to accelerate agent development. Strategic hires and partnerships underscored how valuable ex-Google research talent remains in the AI arms race. Adept now focuses on narrowing its product toward enterprise automation scenarios with clear return on investment.
Cresta – Real-time AI coaching at scale
Cresta operates at the intersection of conversational AI and enterprise operations. Leaders with Google AI backgrounds shaped the company’s technical and product direction, including CEO Ping Wu, who previously led applied AI efforts at Google.
Cresta provides real-time coaching and generative AI tools for contact center agents. The system listens to live conversations, recommends next-best actions, and surfaces knowledge instantly. Large enterprises adopt Cresta to improve customer satisfaction and reduce average handle time.
In 2024, Cresta expanded its generative AI suite and secured larger multi-year enterprise contracts. The company now competes with legacy contact center platforms and newer AI-native vendors, while emphasizing measurable productivity gains.
Waymo – The original Xoogler success story
Sebastian Thrun, former Google engineer and AI researcher, helped launch Google’s self-driving car project, which later became Waymo. While Waymo started inside Google, it stands as the clearest example of what happens when Google talent tackles moonshot problems.
Waymo now operates fully autonomous ride-hailing services in select US cities and continues to expand its commercial footprint. The company logged millions of driverless miles and strengthened partnerships with automotive manufacturers. Waymo’s progress continues to inspire ex-Google founders to pursue technically ambitious startups.
Why ex-Google founders dominate startup ecosystems
Former Google employees benefit from several structural advantages:
- They design systems for massive scale from day one.
- They understand data, infrastructure, and reliability deeply.
- They attract top-tier talent quickly due to strong networks.
- They earn investor trust faster because of proven execution history.
However, Google pedigree alone does not guarantee success. Ex-Google founders still face intense pressure to prove product-market fit, manage burn rates, and sell to demanding enterprise buyers. In 2024, investors showed less tolerance for unfocused experimentation, even for elite teams.
The future of Xoogler-founded startups
The next wave of startups from former Google employees will likely focus on AI agents, infrastructure efficiency, and vertical-specific applications. Many founders now leave Google earlier than before, armed with clearer ideas and faster go-to-market strategies.
As Big Tech continues to partner with, acquire, or rehire talent from these startups, the boundary between incumbents and challengers will blur further. One trend remains certain: when ex-Google employees start companies, the tech industry pays attention.
