Byblos AI Is in Private Beta: Request Access and Shape It

Byblos AI, the AI co-founder platform from StartMeUp AI, is now in private beta. Request access at byblosai.app, bring a real idea, and run it through an AI product manager, brand manager, and campaign manager. We are also live on Product Hunt. Support the launch if the product earns it.

What “Private Beta” Means Here

A private beta means access is granted account by account instead of being open to everyone. For us that is a deliberate choice, not a queue for its own sake.

Limiting access lets us stay close to the first teams using Byblos AI. That means we see where the workflow holds up, where it stalls, and which outputs founders actually keep. Opening the door to everyone at once would give us more signups and far less signal.

So: the agents described below are implemented and running in production. Availability is limited on purpose while we work with early adopters.

What You Can Try Today

Byblos AI is an AI co-founder platform: one project, with specialist AI agents for product, brand, and marketing sharing the same context. Three of them are in the beta.

Sy PM: your AI product manager

Sy PM turns a founder’s context into connected product artifacts: kickoff, empathy research, market and competitor analysis, lean canvas, personas, validation planning, solution planning, and build-ready PRDs and backlog stories.

What makes it more than a document generator is the chain it keeps: explicit dependencies between artifacts, evidence-linked confidence, stale-artifact warnings, and human approvals at each gate.

Brand Manager: your AI brand manager

Brand Manager evolves your positioning into one shared brand system every agent reuses: voice, tone, messaging pillars, visual identity, and governance for logos, colors, and shared assets.

It is stored with the project, so it is not a PDF nobody opens. Other agents read it before they write a word.

Brand strategy lives with the project, so downstream output stays on-brand by default.

Campaign Manager: AI marketing campaigns while you build

Campaign Manager plans multi-channel campaigns for LinkedIn, X, and Instagram, creates and edits posts and images against the brand guidelines, and gives you a content calendar with scheduling and review flows.

What Is Not in the Beta Yet

Being clear about this matters more than a longer feature list.

Co-CTO: the technical co-founder scope covering architecture decisions, delivery planning, GitHub workflows, code review, testing, and documentation. Coming soon.
Byblos AI Pro: the full multi-agent plan. Coming soon.
Code Solutions: near-production-ready codebases you fully own. Coming soon.
Experts Marketplace: coming soon; human expert reviews can already be requested as add-ons.

Byblos AI is also not an autonomous founder. It does not replace real customer conversations, and it will not decide your roadmap for you. Humans stay responsible for evidence quality and consequential calls.

Who the Private Beta Is For

Founders and startup teams: take one idea from kickoff to a build-ready PRD and backlog with Sy PM, without hiring a product manager on day one.
Marketers: set a brand system once with Brand Manager, then plan and schedule on-brand campaigns for LinkedIn, X, and Instagram with Campaign Manager.
Early-stage product people: pressure-test how AI-assisted discovery, validation, and approvals hold up on real work, and shape where the platform goes next.

How to Request Access

Go to byblosai.app and request access.
Bring a problem you actually care about: the beta is far more useful on a real idea than on a test project.
Start with a Sy PM kickoff, then let Brand Manager and Campaign Manager build on that context.

The Feedback We Are Asking For

Early adopter feedback is the whole point of a private beta, and general praise helps us less than specific friction. The questions we most want answered:

Where did an output need heavy editing? Tell us which artifact and what you changed.
Where did the workflow feel like paperwork? Any gate that adds ceremony without adding confidence should go.
What did you keep? The artifacts founders paste into a deck, a repo, or an investor update tell us what is genuinely load-bearing.
What was missing? Especially the moment you left Byblos AI for another tool.

Every one of those makes the next version of the AI co-founder sharper. Send them from inside the app, or reply on the Product Hunt thread.

Support the Product Hunt Launch

Byblos AI is live on Product Hunt. An upvote helps other founders find the platform, and an honest review, including the critical parts, tells us which pieces of the workflow matter most.
