Turn scattered information into business opportunities you can defend.
FNDRBLDR is a workspace for finding, researching and deciding on new ventures. Every claim keeps its evidence, so you can always see why you believe it.
The problem
Venture ideas live in documents, notes and chat threads. AI tools answer confidently, without showing what is fact and what is a guess. Months later, nobody can say why a decision was made, or what would change it.
One workflow, from first signal to funding

What makes it different
Structured knowledge
A knowledge graph of entities, claims and relationships, not a pile of document chunks.
Evidence you can inspect
Each claim links to its source passage. Copies of one story count as one source.
Honest about uncertainty
Facts, hypotheses, inferences and unknowns stay separate, and missing data says “Not established”.
Domain models you control
Ontologies are versioned and need human approval before release.
Several models, no vote-counting
Independent models review each other, disagreement is kept, and agreement never counts as proof.
Memory that lasts
Decisions and rejected ideas are kept, so you can revisit them when the evidence changes.
Who it's for
Founders looking for their next venture, venture studios, investors and researchers, and teams analysing a new business area. See use cases.
What works today
FNDRBLDR is in private early access and being built in stages. Accounts, workspaces and team roles work today. Files, knowledge graphs, research and venture tools are in development, and this site will say when each one ships.
