A plan you can defend
Cited research, tested assumptions, a PRD and a roadmap, each rated for confidence in the final review.
Plan, brand and grow your startup with an AI co-founder
Byblos AI is your AI co-founder: specialised AI agents that work together in one shared project. As a founder, you start with Product Manager to research your market and draft a PRD and roadmap, then build a brand and plan launch campaigns from the same research. You review and approve every step; the Free plan needs no credit card.
The Free plan covers the kickoff interview, a first pass of the research, a Solution Plan, a PRD and the first brand phases. Paid plans add validation, the roadmap and Campaign Manager; Co-CTO and Video Studio are in private beta.

How founders use Byblos AI
Step 1
Research the idea
A kickoff interview captures your problem, audience and goals. Product Manager then drafts cited market and competitor research, personas and a Lean Canvas for you to review.
Step 2
Test what you assume
On a paid plan, list desirability, feasibility and viability assumptions, run real interviews and surveys from the scripts provided, and draw the findings into a UX report.
Step 3
Brand it and plan the launch
Turn the approved research into a brand system in Brand Manager, then draft launch campaigns in Campaign Manager. Nothing is posted until you approve it.
What founders see in Product Manager
What you leave with
A brand ready to use
Strategy, voice, a logo, colours, typography and channel rules, each phase approved by you.
Campaigns waiting for approval
Articles and posts for LinkedIn, X and Instagram with on-brand AI images, published only once you approve them.
Questions founders ask
Can I start before I have a development team?
Yes. On the Free plan, Product Manager runs the kickoff interview and drafts cited market and competitor research, personas, a Solution Plan and a PRD before you hire anyone. A developer, a no-code tool or a coding agent can build from that PRD later, and paid plans add validation and the roadmap.
Does Byblos AI build the product’s code?
No. Byblos AI plans, brands and markets the product; it does not write the code. Co-CTO, in private beta, turns your roadmap into technical decisions and GitHub issues for a developer, a no-code tool or a coding agent connected through MCP. If you want a codebase to start from, the Production Foundation is a one-time $5,900 purchase, sold by request.
My accelerator or incubator wants to support me. How?
Programmes can bring their cohorts to Byblos AI. If yours shares a cohort join link, open it, choose the project to enrol and give your consent, which lists exactly what the programme will see. Enrolling does not add programme staff to your project. If your programme is not set up yet, ask its team to contact us at [email protected].
Will the platform validate my business for me?
No, but it prepares the evidence for your decision. On a paid plan, Product Manager lists desirability, feasibility and viability assumptions, writes interview scripts and surveys, and draws your answers into a UX report. You run the interviews, and the final review rates each artifact’s confidence, so you can see what is validated and what is still an assumption.
