Hark, founded by Figure AI CEO Brett Adcock, previews Handoff, a computer use agent it says outperforms GPT-5.4 and Opus 4.8, and plans for a summer release
Hark, a startup that raised $700 million in Series A funding in May, today launched its agent Hark Handoff, which can use a browser efficiently to complete tasks.
Context & Ripple Effects
Hark raised a $700M-plus Series A for its AI-device effort in May. Handoff adds a browser-using software agent to that ambition, giving the company a nearer-term product surface ahead of any device rollout.
The launch enters a category OpenAI had already defined with ChatGPT Agent’s computer-control capabilities, while hands-on coverage found earlier Operator workflows useful but constrained by what they could browse. Hark is therefore positioning efficiency and model performance as its point of differentiation.
First-order effects
- Hark now has a summer release target for Handoff, putting its performance claims against GPT-5.4 and Opus 4.8 into a product-facing comparison rather than a funding narrative.
- Handoff gives Hark a browser-based task-completion offering alongside its stated AI-device mission, broadening the company’s immediate product pitch.
Second-order effects
- OpenAI and Anthropic become the reference points for Hark’s launch; enterprise buyers evaluating browser agents will have another claimed high-performance option to test against existing agent products.
- Browser access becomes a more important competitive layer: the earlier limits on what Operator could browse make Hark’s efficiency claim relevant to whether agents can complete workflows reliably.
Third-order effects
- If browser agents continue to improve, the work interface shifts from applications operated directly by users toward agentic work surfaces that execute multistep tasks across them.
- Competition may increasingly turn on dependable computer-use execution and distribution, not only on the underlying model named in benchmark comparisons.
The trend: Computer-use agents are becoming a primary product layer for AI companies seeking to automate multistep browser workflows.
