Add a startup's pitch deck and other files. A team of AI helpers reads everything, compares the numbers, checks the company online and writes you a short memo with sources. You decide faster, with fewer surprises.

Meet your AI team
7 specialist helpers and 1 team lead work every deal, and Ask AI answers your questions. The team lead decides who works next, runs helpers at the same time when it can, sends weak work back to be redone, and asks you for missing files. Every agent follows one rulebook, and the key rules are checked in code.
Orchestratorteam lead
Plans the work, decides who goes next and re-checks anything that looks weak.
Scout
Reads every file and pulls out the key facts, numbers, team and claims.
Analyst
Scores how well the startup fits what you invest in, and says how sure it is.
Auditor
Compares your files with each other and flags numbers that don't match.
Investigator
Checks the company and founders online: website, domain age, security, GitHub and news.
Scribe
Writes a short memo where every fact links to the exact line in your files.
Verifier
Double-checks every quote in the memo against your files and sends bad ones back.
Advisor
Suggests invest, watch or pass, and says how confident it is.
Conflicts between files
Founders send a polished deck. The real numbers are in the financials, the Stripe export and the cap table. Thesys reads them together and shows every place they disagree.

What you get
The deck says $2M in revenue but Stripe shows $1.1M? You'll see both numbers side by side.
Is the website real? How old is the domain? Do the founders' backgrounds and press claims hold up?
Tell Thesys what you invest in once. Every deal gets a clear 0–100 score with the reasons.
Every fact links to the exact line in your files, and every quote is double-checked.
"Why did I pass on that fintech last spring?" Ask in plain words and get an answer with links.
It writes the questions the files leave open. You edit them, send in one click, and the deal is re-checked when the founder answers.
Send co-investors a link to the memo, score and checks. Your files and notes stay private, and the link expires.
See what the AI team does with mismatched numbers, a clean data room, a thin deck and a red-flag company.
The AI suggests invest, watch or pass and says how sure it is. The decision is always yours.

Ask AI
Every decision you save is remembered with your reason. Later, just ask: "Show me every fintech I passed on because of valuation." It also explains how Thesys works and searches the web when a question needs fresh facts, with sources.
