Petra

⚠️ IDENTITY / DISAMBIGUATION (this was a “stealth fund” in the CRM). Our Petra is “Petra Fund I, LP” — the new early-stage fund of Lukas Linemayr (Co-Founder & GP; Lukas@petra.fund). The identity is locked by a primary source + a phone match: the SEC Form D for “Petra Fund I, LP” (CIK 0002128387, Delaware LP, filed 2026-04-10) lists business address 595 Pacific Ave, San Francisco and phone 603-501-9251 — the exact phone number recorded for Lukas in init.inc’s CRM. ✅ It is NOT:

  • Petra Funds Group (petrafundsgroup.com) — a private-equity fund administrator, unrelated.
  • Petra Capital Partners / Petra Diamonds / any other “Petra” — unrelated.

Firm Profile

New, small early-stage fund (“Petra Fund I, LP”). SF-based (595 Pacific Ave, 94133); first institutional vehicle for Lukas Linemayr.

  • Vehicle & vintage. Petra Fund I, LP — Delaware LP, SEC Form D filed 2026-04-10, exemptions Item 06b + 3(c)(1) (the ≤100-investor private-fund exemption → a small first fund). EIN on file; SF business address. The “Fund I” label + 3(c)(1) exemption mark it as brand-new and small. ^[SEC Form D]
  • Fund size. Not disclosed on the Form D index (offering amount not surfaced). Given a debut 3(c)(1) vehicle, plausibly a small/SPV-adjacent first fund ^[inferred — UNVERIFIED]. (COULDN’T-GET: exact target/raised size.)
  • Thesis. Per the CRM pass note, Petra is “fully aligned on labor-automation thesis” — i.e., explicitly on-thesis with init.inc — but invests at a later/“more proven” archetype than init.inc’s current stage. Treats stage-fit as the gate.
  • Stage / check. Early-stage but “too early for their typical archetype” was init.inc’s specific rejection reason — implying they want a bit more traction/conviction than init’s current point. Check size not disclosed (COULDN’T-GET).
  • GP background. Lukas Linemayr — Co-Founder & GP of Petra. Previously Principal/Partner at Streamlined Ventures (Ullas Naik’s seed fund); began career at A.T. Kearney (TMT & PE practices); Babson College (B.S. Finance & Entrepreneurship). ⚠️ Public profiles (LinkedIn/The Org/NFX) still show him at Streamlined — Petra is his new, not-yet-fully-public vehicle (consistent with the CRM “stealth fund” label).

Partners

  • Lukas Linemayr — Co-Founder & General Partner; init.inc’s POC. Lukas@petra.fund · phone 603-501-9251 (matches SEC Form D). Met 1:1 by Sazzad 2026-05-04, then the Petra team 2026-05-05. Friendly, thesis-aligned, soft-passed on stage. ✅ (CRM + SEC-corroborated identity.)
  • “Petra team” (2026-05-05 meeting) — additional members exist but are unnamed in available sources. ^[needs-research] (No separate POC stub created — Lukas is the sole named contact.)

Recent pre-seed/seed activity (Pass-1 sketch — ≤5 deals; exhaustive 18–24mo pull is Pass 2)

Full source-tagged data → /Users/sazzad14/seed-market-scan/firms/petra.csv.

  • No Petra-attributed deals located — the fund is brand-new (Form D Apr 2026) and stealth; no portfolio is public yet. (COULDN’T-GET: Petra Fund I deal list.)
  • Lukas’s prior deal track record lives under Streamlined Ventures (Ullas Naik’s fund) — out of scope for “Petra” attribution; flagged in the CSV as context only.

Best data channels for this firm

  • SEC EDGAR / formds.com (CIK 0002128387) — the ONLY authoritative anchor for the vehicle; watch here for fund-size disclosure on future amendments.
  • Lukas Linemayr’s LinkedIn / NFX Signal — currently lag (still show “Streamlined”); will be the channel once Petra goes public.
  • ⚠️ Avoid all “Petra Funds Group” / “Petra Capital” results — different entities (see disambiguation).
  • For deal history, mine Streamlined Ventures sources for Lukas-era deals (prior firm, not Petra).

Fundraise Relationship (init.inc)

  • Status: DEAD (stage-too-early soft pass). This is one of the friendliest passes in the pipeline: thesis-aligned, relationship intact, explicit invitation to re-engage. Petra said the gate was stage/archetype, not fit.
  • Re-touch trigger (their words): “in a few months” — once init.inc has the traction/conviction Petra said it lacked. Lukas said he wants to “earn the right to partner in a future round.” Contact: Lukas (Lukas@petra.fund / phone).
  • Conversation log (newest first, from CRM):
    • 2026-05-12, 11:47 PM — PASS via email: “stage too early for our typical archetype — fully aligned on labor-automation thesis but need more conviction. Hope to earn the right to partner in a future round. Let’s catch up in a few months.” → friendly soft pass, kept warm.
    • 2026-05-05 — Met the Petra team (Tue).
    • 2026-05-04 — Sazzad met Lukas 1:1 (Mon).
    • 2026-04-27 — Toms Ce intro’d.
  • Mutual connections / warm path: intro’d via Toms Ce. Lukas is the direct contact for re-warm.
  • Personal & rapport notes: thesis-aligned and personally warm; the relationship is an asset for the next round. The blocker was purely stage/archetype, not fit.
  • Live stage: tracked in the CRM (Google Sheet) — Lost (soft pass / kept warm).

Cross-check vs existing wiki

  • No cap-table conflict found. Petra does not appear in cap-table-patterns-across-startup-competitors (brand-new fund, no known portfolio). Dead = stage-fit soft pass, not conflict. ✅
  • Toms Ce (connector) page references Petra — creating this page resolves that link. ✅
  • ⚠️ Streamlined Ventures also appears in init.inc’s CRM (Ullas Naik path, separately Lost — intro never landed). Lukas is the bridge between the two (ex-Streamlined → now Petra). Noted as a relationship edge; not a contradiction.

Pass 2 deal pattern (2026-05-27)

No Petra-attributed deals public — re-confirmed. Pass-2 verification sweep (“Petra Fund Linemayr portfolio investment 2026”, “Lukas Linemayr 2025 2026 investment”) returned only: (a) Streamlined Ventures lag-results (LinkedIn/NFX/TheOrg still show Lukas at his prior firm); (b) Petra Capital Partners (Tennessee growth-equity, Petra Growth Fund V $270M, latest deal Lieberman Jan 2025 — NOT our Petra); (c) Petra Funds Group (PE fund admin acquired by Charlesbank Oct 2023 — NOT our Petra). Identity remains locked solely by the SEC Form D / phone match (CIK 0002128387, 603-501-9251 = Lukas’s CRM phone). COULDN’T-GET: any Petra Fund I LP-attributed deal as of 2026-05-27. Fund offering amount also still undisclosed on Form D.

Lead-rate / check / stage: all unknown — no portfolio is public. The only behavioral signal is the rejection itself (“stage too early for our typical archetype” — implies they want post-PMF / metric-driven seeds, not the earliest pre-product stage init.inc was at). Best data channel: SEC EDGAR (CIK 0002128387) is the ONLY authoritative current channel — watch for Form D amendments (offering-size disclosure) or new filings. LinkedIn/NFX still lag (show Streamlined). Lukas direct (Lukas@petra.fund) is the relationship channel, not a data channel. Disambiguation hardened: strictly ignore all Petra Capital Partners, Petra Funds Group, Petra Diamonds results in any future Pass — only “Petra Fund I, LP” (CIK 0002128387, Linemayr) is in-scope.
