Presidio security-hardened deal-flow triage & due-diligence toolkit for early-stage AngelList syndicate deals

presidio-hardened-angellist

Presidio security-hardened deal-flow triage & due-diligence toolkit for early-stage (pre-seed / seed) startups sourced via AngelList syndicates.

Why not an API client? The legacy AngelList Startup/Funding Data API (api.angel.co) has been shut down — AngelList today is fund/SPV infrastructure, not an open data API. So this toolkit triages the deal flow you actually receive — forwarded syndicate deal emails — instead of calling a dead endpoint. The original Presidio hardening layer is retained and reused for every outbound enrichment call.

How it works

forwarded .eml ─▶ intake ─▶ extraction ─▶ enrichment ─▶ triage rubric ─▶ memo
                  (parse)   (regex first,  (hardened     (deterministic   (Claude or
                            LLM fallback)   HTTP fetch)    scorecard)       template)

1. Intake — parse a forwarded .eml (or pasted text) into a structured Deal.
2. Extraction — deterministic regex/heuristics first; Claude fallback only when the parse is too thin (is_complete() is False).
3. Enrichment (opt-in) — fetch the company website through the hardened session to backfill a one-liner.
4. Triage — score against a deterministic pre-seed/seed rubric → composite + tier (Pass / Track / Dig deeper / Strong lead).
5. Memo (opt-in) — Claude-assisted investment memo, with a templated fallback so --memo still works with no API key.

The deterministic path needs no API key. The LLM steps activate only when ANTHROPIC_API_KEY is set and the [llm] extra is installed.

CLI usage

angeltriage deal.eml                 # scorecard for one deal
angeltriage deal.eml --memo          # + investment memo
angeltriage deal.eml --enrich        # fetch the company site for more signal
angeltriage deal.eml --json          # machine-readable output (pipe-friendly)
cat deal.txt | angeltriage -         # read a pasted email from stdin
angeltriage *.eml                    # batch, ranked by composite score
angeltriage deals.csv                # batch-triage a CSV of deals (one row each)
angeltriage --imap                   # pull deal emails over IMAP (see below)
angeltriage --watch --interval 300   # poll IMAP every 5 min, auto-triage new deals
angeltriage deal.eml --no-llm        # force the deterministic-only path
angeltriage deal.eml --weights w.json  # tune dimension weights (see below)
angeltriage deal.eml --rubric r.json   # full rubric config (see below)
angeltriage deal.eml --save          # persist to the deal queue (see below)
angeltriage --queue                  # show the ranked, saved deal queue
angeltriage --set-status 4 passed    # update a saved deal's workflow status

.eml/text inputs are parsed as emails; .csv inputs are triaged a row at a time. You can mix files in one batch — everything is ranked together by score.

Example output:

Nimbus Robotics  [Strong lead · 83.0/100]
  pre-seed · SAFE · $10,000,000 cap · lead: Jane Okafor
  Warehouse-automation robots for SMB 3PLs.

  Scorecard:
    Team       4.5/5   2 founders; credential signals: ex-, former, mit
    Market     3.5/5   clear one-liner present
    Traction   4.5/5   signals: customers, month-over-month, mrr, paying
    Terms      4.0/5   cap $10,000,000; SAFE
    Syndicate  4.0/5   lead: Jane Okafor; allocation $250,000

Library usage

from presidio_angellist import triage_email

result = triage_email("deal.eml", memo=True)
print(result.scorecard.tier, result.scorecard.composite)   # Strong lead 83.0
print(result.deal.valuation_cap)                            # 10000000.0
print(result.memo)

Tune the rubric weights:

from presidio_angellist import score_deal, parse_email

deal = parse_email("deal.eml")
sc = score_deal(deal, weights={"team": 0.4, "market": 0.2, "traction": 0.2,
                               "terms": 0.1, "syndicate": 0.1})

Triage rubric (pre-seed / seed)

Dimension	What it weighs
Team	Founder count, technical co-founder, credential signals (ex-FAANG, YC, etc.)
Market	Crispness of the one-liner / sector framing
Traction	Revenue, users, LOIs, growth — any early signal
Terms	Valuation cap sanity for the stage, instrument (SAFE/priced)
Syndicate	Named lead, allocation, social proof

Risk flags (solo founder, missing cap, cap too high for stage, no traction, no website) are surfaced separately.

Out-of-scope (growth-stage) detection

The rubric targets pre-seed / seed. When a deal looks later-stage — an explicit Series A/B/C, ARR/revenue ≥ $5M, or a priced/venture round with a large round size — it's tagged Out of scope with a note (e.g. "Likely growth-stage (~$40M ARR; venture round $20M) — outside pre-seed/seed scope; score is indicative only") instead of being given a misleading tier. The composite is still computed, but flagged as indicative. Exposed as detect_stage_scope(deal) and Scorecard.scope_note.

Tuning the weights

Weights live in DEFAULT_WEIGHTS and are overridable per call, or from a JSON config file via --weights:

{
  "team": 0.5,
  "traction": 0.3
}

angeltriage deal.eml --weights weights.json

Dimensions you omit keep their default weight (so partial overrides are fine), weights need not sum to one (the composite normalizes by total weight), and at least one must be positive. Valid dimensions: team, market, traction, terms, syndicate. From the library:

from presidio_angellist import load_weights, triage_email

result = triage_email("deal.eml", weights=load_weights("weights.json"))

Full rubric config (--rubric)

For more than weights, pass a --rubric file. All sections are optional and merge over the defaults:

{
  "weights": { "team": 0.4, "traction": 0.25 },
  "tier_thresholds": { "Strong lead": 90, "Dig deeper": 75 },
  "cap_ceilings": { "pre-seed": 8000000, "seed": 25000000 },
  "risk_penalty": 5.0
}

• tier_thresholds — minimum composite (0–100) for each tier label. The Pass floor at 0 is always retained.
• cap_ceilings — per-stage valuation-cap ceiling (USD); caps above it raise a risk flag and dock the Terms score.
• risk_penalty — composite points deducted per risk flag (default 0).

angeltriage deal.eml --rubric rubric.json   # mutually exclusive with --weights

from presidio_angellist import load_rubric_config, triage_email

result = triage_email("deal.eml", config=load_rubric_config("rubric.json"))

Validation fails closed — unknown keys/dimensions, out-of-range thresholds, negative penalties, or malformed JSON raise WeightsConfigError.

CSV batch import

angeltriage deals.csv triages one Deal per row. Headers are matched case-insensitively against common aliases:

Field	Accepted headers (any of)
company	company, name, startup
valuation_cap	valuation_cap, cap, valuation
round_size	round_size, raising, round, target
website	website, url, site
founders	founders, founder, team (split on ; / ,)
…	one_liner, sector, stage, instrument, allocation, lead, deadline, location, traction, links

Money cells accept $1.2M, 1,200,000, or 500k. Rows without a company are skipped.

from presidio_angellist import triage_csv

for result in triage_csv("deals.csv"):
    print(result.deal.company, result.scorecard.tier)

IMAP intake

--imap pulls deal emails straight from a mailbox (file syndicate emails into a folder, then poll it). It runs wherever you run it — your laptop or a server, not a phone. Credentials come from the environment only (never the command line) — use an app-specific password (iCloud, Gmail with 2FA):

export IMAP_HOST=imap.mail.me.com      # iCloud; Gmail: imap.gmail.com
export IMAP_USER=[e-mail]
export IMAP_PASSWORD=abcd-efgh-ijkl-mnop   # app-specific password
export IMAP_FOLDER=Deals               # optional; defaults to INBOX

angeltriage --imap --save              # fetch UNSEEN, triage, save to the queue
angeltriage --imap --imap-all --imap-limit 20    # most recent 20, read or not
angeltriage --imap --imap-from [e-mail]

Env var	Purpose
IMAP_HOST / IMAP_USER / IMAP_PASSWORD	Required connection + app-specific password
IMAP_PORT	Optional, default 993
IMAP_FOLDER	Optional, default INBOX (or use --imap-folder)
IMAP_SSL	Optional, default on (0/false to disable)

Flags: --imap-folder, --imap-all (not just UNSEEN), --imap-from ADDR, --imap-limit N. The mailbox is opened read-only, so messages aren't marked read — re-polling re-fetches them and the deal queue dedups by deal identity.

from presidio_angellist import imap_config_from_env, triage_imap

cfg = imap_config_from_env(folder="Deals", limit=20)   # reads IMAP_* env vars
for result in triage_imap(cfg):
    print(result.deal.company, result.scorecard.tier)

Watch mode (continuous polling)

--watch polls the mailbox on an interval and auto-triages new deals into the queue — a hands-off inbox-to-queue pipeline:

angeltriage --watch --interval 300        # poll every 5 min until Ctrl-C, saving new deals
angeltriage --watch --max-cycles 12       # poll 12 times then stop

Within a session, messages are deduped by Message-ID so the same unread email isn't re-triaged every poll; across restarts the deal queue dedups by deal identity. The first poll fails fast on a bad config/credentials; later polls tolerate transient network errors and keep going. Each poll prints a one-line summary plus any newly-saved deals. For a cron-style setup, use --max-cycles 1 on a schedule instead of a long-running process.

from presidio_angellist import DealStore, imap_config_from_env, watch

with DealStore() as store:
    watch(imap_config_from_env(folder="Deals"), store, interval=300)

⚠️ Don't put your mail password in a shared/remote shell. Keep it in a local .env / your shell profile, scoped to where you run the tool.

---

Deal queue (persistence)

--save persists triaged deals to a local SQLite store so triage becomes a workflow you work over time, instead of one-shot:

angeltriage inbox/*.eml --save           # triage + save the batch
angeltriage --queue                      # ranked list of everything saved
angeltriage --queue --status new         # filter by workflow status
angeltriage --set-status 4 tracking      # new -> tracking -> passed -> committed

  #  tier         score  status     seen  company
  1  Strong lead   83.0  tracking      2  Nimbus Robotics
  3  Track         49.5  new           1  Solo Stealth

• Dedup across runs — deals are keyed by website domain (or normalized company name when there's no site), so the same deal forwarded by two syndicates collapses to one row. seen counts how many times it arrived.
• Status is preserved on re-save — re-triaging a passed deal won't reset it to new; only the scorecard/score refresh.
• Store location — ~/.angeltriage/deals.db by default; override with --db FILE or the ANGELTRIAGE_DB env var. The DB is local; nothing leaves your machine.

from presidio_angellist import DealStore, triage_email

with DealStore() as store:                       # default path, or DealStore("deals.db")
    saved, is_new = store.save(triage_email("deal.eml"))
    for row in store.list(status="new"):
        print(row.id, row.company, row.tier, row.composite)
    store.set_status(saved.id, "tracking")

Security hardening (retained, reused for enrichment)

Feature	What it does
Strict TLS 1.2+ enforcement	Rejects TLS 1.0/1.1; ephemeral-EC ciphers only; verify=True always
HTTP → HTTPS auto-upgrade	Insecure http:// URLs are silently upgraded; non-HTTP(S) schemes refused
SSRF guard	Refuses targets resolving to loopback/private/link-local (incl. 169.254.169.254)/reserved addresses
API key / secret redaction	RedactingFilter on the presidio_angellist logger scrubs Bearer tokens, sk_live_* / sk-ant-* keys, and access_token=/api_key= from every log record
Retry with backoff	Exponential backoff on connection errors / 429 / 5xx, honouring Retry-After
Per-host rate limiting	Token-bucket limiter; prevents accidental DoS of enrichment hosts
Security event logging	Structured logs for every hardening action (presidio_angellist logger)

Every outbound enrichment request goes through HardenedSession. Untrusted deal text sent to the optional LLM layer is fenced and the system prompt treats it as data, not instructions (prompt-injection defense); plaintext IMAP is refused unless explicitly opted in. See SECURITY.md for the full trust-boundary model.
