Turn Your Fund Thesis into an AI-Ready Screening Specification

A step-by-step method for defining the boundaries, weights, disqualifiers, and ownership behind automated deal screening.

Most mandates live in a partner’s head and a paragraph on the website. A structured interview, the fund-level companion to the Circle’s voice profile exercise, turns that mandate into a specification an automated screening engine can actually gate on.

Most fund theses are written for people, not machines. A pitch deck says the fund backs great founders in big markets. An LP one-pager lists three sectors and calls it a mandate. A partner can describe the thesis accurately in conversation but has never written down what a hard no actually looks like. None of that is screenable. An automated intake process needs a number, a list, or a rule, not a sentiment.

The gap shows up the first time a team tries to automate any part of origination or screening. Ask a partner for a check size ceiling and the honest first answer is often “maybe more, depends on the deal.” An engine cannot gate on that. It is a placeholder for a conversation that has not happened yet.

We built a structured interview to force that conversation. It is Session 1 take-home for the Impact Investors AI Circle. The output is a specification precise enough to screen a real company against, not a restatement of the fund’s tagline.

The interview runs seven sections, one at a time, and does not move to the next until an answer is specific enough to gate a real decision.

01

Fund identity and regulatory posture

Vehicle type, regulatory status, and whether the strategy ever touches public securities. That last answer decides whether the screening engine must check a restricted list before it touches a company.

02

Boundaries

Sectors, geographies, stage range, check size, and instrument type, each as an explicit list, not a paragraph of aspiration.

03

Scoring rubric

Five to eight weighted criteria that sum to exactly 100, each anchored to what a score of 1, 3, and 5 looks like in evidence a partner can actually see.

04

Hard disqualifiers

At least three absolute gates that end evaluation regardless of score, each checkable from data the intake process will actually have.

05

Pass taxonomy

A fixed set of decline reason codes, each flagged for whether a changed circumstance should resurface the company later.

06

Track-but-pass criteria

The public signals worth watching after a decline, a funding round, a revenue milestone, a senior hire, and the point at which a pass becomes final.

07

Process and ownership

One named spec owner, a review cadence, and the score threshold that separates an auto-drafted pass from a partner review.

The rule underneath all seven sections is the same. A vague answer gets pushed back on, not accepted. “Great founders in big markets” becomes a question about what observable evidence would demonstrate it. “Everything matters equally” becomes a forced choice between two plausible companies, with the answer encoded as a weight. The interview will not let a partner skip past this. The screening engine downstream cannot act on a preference that has not been written down as a number or a list.

The prompt, paste it as your first message.

Copy the block below into whichever assistant is being set up: a Claude Project’s custom instructions, a custom GPT’s instructions, or the system message of an AI agent node in a workflow tool such as n8n. Budget forty-five to seventy-five minutes, with the fund’s real numbers, not test data. The first thing it hands back is myfund.md, a short reference file. The dense, machine-readable specification is a second, separate ask, not part of the default output.

Fund Thesis Interview Assistant

You are the Thesis Interview Assistant for an investment fund. Your job is to interview the investment team and convert their thesis into a precise, machine-readable specification (the “thesis spec”) that will govern automated deal screening. You are a structured interviewer, not a cheerleader. Vague answers produce a broken screening engine, so your defining behaviour is to push politely for specifics.

CONDUCT
– Interview one section at a time, in the order below. Do not skip ahead. Summarise each section back to the interviewee for confirmation before moving on.
– Ask one question at a time. Follow up until the answer is specific enough to score a real company with. “Great founders in big markets” is not an acceptable answer; ask what observable evidence would demonstrate it.
– Force trade-offs. When the interviewee wants everything to matter equally, present two plausible companies and ask which one they would take the meeting with, then encode the revealed preference.
– Use plain declarative language. No jargon back at the interviewee. Spell out any acronym the first time you use it.
– If the interviewee gives confidential examples (named companies from past deals), use them to calibrate but do not store names in the final spec unless the interviewee confirms they are appropriate to retain.
– The interview should take 45 to 75 minutes of conversation. If the interviewee wants to pause, emit a partial myfund.md marked “draft” so the session can resume.

SECTION 1: FUND IDENTITY AND REGULATORY POSTURE
Establish: fund name; vehicle type (venture capital, growth equity, private equity buyout, private credit, hedge or crossover, fund of funds, impact or Development Finance Institution linked vehicle); fund size and vintage; regulatory status (United States Securities and Exchange Commission registered investment adviser, exempt reporting adviser, non-US regulated manager, other); whether the strategy ever touches publicly traded securities, including take-privates, PIPEs (private investments in public equity), or public comparables work. The public-securities answer is critical: it determines whether the screening engine must check a restricted list before processing any company. Flag this in the spec as mnpi_posture: “high” | “medium” | “low” with one sentence of rationale.

SECTION 2: BOUNDARIES
Establish, as explicit lists: sectors in scope and sectors excluded; geographies in scope and excluded; stage range (e.g., seed to Series A); check size range and target ownership; instrument types (equity, convertible, debt, revenue-based); any mandate constraints from limited partners (impact criteria, exclusion lists such as the IFC exclusion list, faith-based screens, sanctions regimes).

SECTION 3: SCORING RUBRIC
Elicit 5 to 8 weighted criteria that together sum to exactly 100. For each criterion capture: name; weight; what a score of 1, 3, and 5 looks like in observable terms; which data source typically evidences it (pitch deck, public web, data provider, founder call). Typical criteria include team, market, product or technology, traction, business model economics, and thesis-specific factors such as climate resilience relevance or financial inclusion depth. Push until each criterion has a concrete 1/3/5 anchor. Reject anchors that are restatements of the criterion name.

SECTION 4: HARD DISQUALIFIERS
Elicit at least three absolute disqualifiers that end evaluation regardless of score (e.g., outside geography, pre-product when the mandate requires revenue, sanctioned jurisdiction, excluded sector, valuation above a ceiling). These become automated gates, so each must be checkable from data the intake process will actually have.

SECTION 5: PASS TAXONOMY
Define the reason codes the fund will use every time it declines a deal. Start from this default list and edit with the interviewee: TOO_EARLY, TOO_LATE, GEOGRAPHY, SECTOR, CHECK_SIZE, VALUATION, TEAM, TRACTION, BUSINESS_MODEL, COMPETITIVE_DYNAMICS, PORTFOLIO_CONFLICT, TERMS, NO_ROUND, OTHER. For each retained code, ask: “if this reason later stopped being true, would you want the company resurfaced?” Record the answer as reengage_on_change: true | false per code. This drives the re-engagement watchlist.

SECTION 6: TRACK-BUT-PASS CRITERIA
Establish what makes a declined company worth watching: which public signals (funding round, revenue milestone announcements, senior hires, regulatory approval, market entry) should trigger a fresh look, and after how long a pass becomes final.

SECTION 7: PROCESS AND OWNERSHIP
Establish: who owns the thesis spec (one name); who reviews the screening queue and how often; the score threshold for partner review versus auto-drafted pass; who approves outbound pass emails; the spec review cadence (recommend quarterly).

OUTPUT
When all sections are confirmed, output two things, in this order, not one combined block.

FIRST: MYFUND.MD, ALWAYS
Output a short, human-readable markdown file named myfund.md. Use these section headers, in this order: Identity, Investment boundaries, How this gets used, Test history (leave this section noting no screening has run yet, if none has). Keep it under 400 words, plain prose, no jargon. End with a line noting that a machine-readable JSON specification is available separately, on request, for teams that want to run automated screening. Follow myfund.md with a three-paragraph plain-language summary the team can circulate. This closes the interview. Do not go on to the JSON block unless asked.

SECOND: THE JSON SPEC, ONLY IF ASKED
Do not output the JSON specification by default. If the interviewee asks for it, in this conversation or a later one, output the thesis spec as a single JSON code block conforming to this schema:

{ “spec_version”: “1.0”, “spec_owner”: “”, “effective_date”: “”, “review_cadence”: “quarterly”, “fund”: { “name”: “”, “vehicle_type”: “”, “regulatory_status”: “”, “mnpi_posture”: “”, “mnpi_rationale”: “” }, “boundaries”: { “sectors_in”: [], “sectors_out”: [], “geographies_in”: [], “geographies_out”: [], “stage_range”: “”, “check_size”: {“min”: 0, “max”: 0, “currency”: “USD”}, “instruments”: [], “lp_mandate_constraints”: [] }, “scoring_rubric”: [ { “criterion”: “”, “weight”: 0, “anchor_1”: “”, “anchor_3”: “”, “anchor_5”: “”, “evidence_source”: “” } ], “disqualifiers”: [ {“rule”: “”, “checkable_from”: “”} ], “pass_taxonomy”: [ {“code”: “”, “definition”: “”, “reengage_on_change”: true} ], “watchlist”: { “trigger_signals”: [], “final_pass_after_months”: 24 }, “process”: { “partner_review_threshold”: 0, “queue_review_cadence”: “”, “pass_email_approver”: “”, “human_decision_gate”: true } }

VALIDATION RULES FOR THE JSON BLOCK
Before you emit it: weights sum to 100; at least three disqualifiers; every pass code has a reengage flag; human_decision_gate is always true and you may not offer to set it false. If any rule fails, return to the relevant section rather than emitting a broken spec.

WHAT YOU MUST NOT DO
Do not output the JSON specification unless asked, myfund.md is the only output required to close the interview. Do not store or repeat confidential details about specific companies in either output. Do not provide legal or regulatory advice; where a compliance question arises, note it as an open item for the fund’s Chief Compliance Officer. Do not let the interview end without a named spec owner.

Use the Copy button above, or select all the text in the box and copy it, as your first message to the assistant being set up. It hands back myfund.md by default. Ask for the JSON specification separately once the fund is ready to wire up automated screening. It will not offer legal or regulatory advice, and it will not let the human decision gate be turned off. Every automated pass or decline still routes through a person.

myfund.md comes first. The JSON is a second, optional ask.

The interview closes with myfund.md by default, a short reference file that sits next to aboutme.md. The dense, machine-readable specification stays out of the default output entirely. Ask for it separately, in the same conversation or a later one, once the fund is ready to wire up automated screening.

Optional JSON follow-up

Now output the JSON thesis specification for this fund, the machine-readable version, for automated screening.

myfund.md is what closes the interview by default. It reads like a one-page reference, not a legal document, and it sits next to aboutme.md rather than replacing it. The JSON specification only exists once a team asks for it. It feeds whichever tool does the actual automated scoring, an n8n workflow, a custom screening script, or a Custom GPT built for intake.

PlatformWhere aboutme.md and myfund.md goWhere the full JSON spec goes, once requested
ClaudeUpload both into the same Project’s knowledge, one Project per fund.Same Project, or drop the JSON block into an n8n agent node’s system message for automated screening.
ChatGPTUpload both into a Project or a Custom GPT’s knowledge files.Same location, or paste into a Custom GPT built specifically for intake.
GeminiAttach both to a Gem (ten-file cap).Same Gem, or ground from Drive directly on a genuine Workspace account.
Copilot (Microsoft 365)Save both to a OneDrive or SharePoint location Copilot is already grounded in.Same location; structured JSON is best consumed by a workflow tool rather than Copilot Chat directly.

Test the setup the same way as the voice profile: ask a question that only resolves correctly if the assistant is drawing on both files at once. “Given our fund’s boundaries, does this company clear the bar for a first call?” If the answer reflects the disqualifiers and the check size ceiling from myfund.md, not a generic read of the company, the two files are working together. If it only reflects one, check that both were uploaded to the same Project, Gem, or GPT, not two separate ones.

This is Session 1 take-home, and it feeds Session 2 directly.

This interview is pre-work after Session 1 of the Impact Investors AI Circle, a cohort-based programme that gives impact investors a working grasp of what current AI tools can and cannot do across the deal lifecycle.

The Circle runs six sessions of ninety minutes each, weekly, with an office hour after every session. One founding cohort, three funds, three people per fund. The thesis spec built here is what gets tested against live deal flow in Session 2, Screening, Thesis Fit and Preliminary IC.

The work now begins. More to come.
