Product f() has launched Beta 2 and invited the first 50 participants to work with the upgraded system. This first cohort of product teams and founders is now inside the product, and the waitlist is open for the next group.
Product f() runs on models from Claude, Gemini, OpenAI, Grok, and others, with model choice available per session, per function, and per agent - so teams are never locked to one provider. The Workbench connects every run, ticket, agent action, approval, and Brain entry as a card you can open in context, with long runs pauseable and stoppable from one place. Over 180 f() functions span the full product lifecycle - research, ideation, design, development, testing, delivery, and release - each with a plain title and a consistent address that works across the product, in chat history, and in connected tools. Agents work from tasks with reviewable steps, and anything that acts beyond the workspace waits for approval before it proceeds. Connectors bring live context from the tools teams already use. Brain holds persistent product memory for the whole team - searchable, cited in every run, and available as an MCP server so that context travels wherever the work is. Interface themes let each person set the environment that suits them.
The system is built for a team. Brain retains the context of every decision, every run, and every piece of product work across the whole workspace - so the second person who needs it does not have to reconstruct what the first already knew. Connectors keep the operating layer connected to the tools the team already uses. Files keep working material attached to the decisions that shaped it. The full surface - Workbench, Brain, Agents, Functions, Connectors, and Files - is what early access participants are working with now.
The first 50 users are product managers, founders, and operators working with real product cycles. They applied with a commitment to genuine feedback, and the team will work closely with them to surface where the operating model earns its place and where it needs to go further.
The next cohort is now forming. Teams and individuals working in product who want early access can join the waitlist through the Product f() beta form. The team reviews each application and prioritises people with active product work and a willingness to report honestly on what works and what does not.
