Fryderyk Wiatrowski is the co-founder and chief executive of Viktor, an AI coworker for Slack and Microsoft Teams that uses a company’s existing software to complete everyday work. His defining ambition is a shared AI coworker that understands an organization without letting sensitive information travel indiscriminately between employees.
Wiatrowski studied mathematics and computer science at Oxford, led the Oxford University Computing Society, and organized hackathons and introductory programming initiatives. Before becoming a founder, he worked at Optiver and Meta.
In 2023, he and fellow Meta engineer Peter Albert founded Zeta Labs to build AI employees. Their early agent navigated websites by interpreting compressed representations of webpages, giving it access to software without dedicated integrations. But multistep browser automation proved slow and unreliable, prompting a shift toward Jace, an email agent that could schedule meetings, draft replies, and trigger actions such as refunds, with approvals where appropriate.
Viktor followed in February 2026, expanding this approach from individual inboxes to an entire organization. One employee can connect workplace tools that others access through a shared agent, subject to appropriate permissions. In May, Accel led Viktor’s $75 million Series A.
Automate operational noise, preserve human judgment. Hiring requires consequential decisions; scheduling interviews generally does not. Wiatrowski designs agents around reactive tasks triggered by emails, messages, or support requests, allowing people to retain oversight of higher-stakes choices.
Make organizational context useful without making it porous. A company-wide agent encounters executive discussions, engineering channels, private messages, and conflicting instructions. Memory isolation and access control determine what it can reveal or do. When a customer inadvertently shared a personal email integration across a team, Viktor added finer-grained integration scoping.
Design agents around workplace behavior. Slack threads, message edits, deletions, direct messages, and conversational tone affect how an agent should interpret tasks and retain context. Asynchronous messaging also changes expectations: work that feels slow in a standalone application can feel remarkably fast when delegated to a coworker. His AI Engineer presentation on Viktor connects those interface decisions with privacy and trust.
Compete through execution and positioning. In an essay about competing with frontier-model companies, Wiatrowski argues that startups can differentiate through distribution, speed, and multiplayer AI employees grounded in real organizational workflows.
Viktor’s evolution from browser automation to a shared Slack agent shows why company context, conversation continuity, permissions, and personality matter as much as tool use.
Start with the work an agent can pick up without being asked, then build its capabilities through better prompts, explicit state, fine-tuning and feedback.
