Investment-fund research reviewed 2026-10-06. Publicly identified funds, dates, amounts and fundraising status are below. Undisclosed commitments remain unknown; this is not a complete register of private SPVs or parallel entities.
Fund size and stages
| Vehicle | Amount / status | Vintage and timing | Evidence |
| --- | --- | --- | --- |
| Altos Korea Opportunity Fund 7, L.P. | **USD 350M offering; USD 350M sold; USD 0 remaining**. Sold figure includes LP and GP commitments.

Latest-known newer fund verified in this review. | [SEC original XML](https://www.sec.gov/Archives/edgar/data/2117687/000211768726000001/primary_doc.xml ), [SEC filing index](https://www.sec.gov/Archives/edgar/data/2117687/000211768726000001/0002117687-26-000001-index.htm ) |
| Altos Hybrid 6, L.P. | **USD 500M offering; USD 500M sold; USD 0 remaining**. Fully subscribed as reported in filing; not firm-wide AUM. | 2024 formation; first sale 2024-09-26; Form D filed/signed 2024-10-07; 65 investors. | [SEC original XML](https://www.sec.gov/Archives/edgar/data/2019043/000201904324000001/primary_doc.xml ), [SEC filing index](https://www.sec.gov/Archives/edgar/data/2019043/000201904324000001/0002019043-24-000001-index.htm ) |
The baseline's November 2024 wording confuses reporting time with fund filing chronology: **Hybrid 6 reported USD 500M sold in October 2024; TechCrunch covered it November 12**. [TechCrunch, 2024-11-12](https://techcrunch.com/2024/11/12/altos-ventures-an-early-backer-of-coupang-and-roblox-raises-500m-fund/ ).
AUM is unresolved and should be separately dated: the inherited USD 8B regulatory-AUM statement was not verified. FilingExplorer reports USD 5,448,790,139 discretionary AUM from a 2026-07-07 Form ADV. This is a **secondary transcription**, not adopted as independently verified current AUM; the official ADV PDF could not be parsed with available tools. A 2021 company announcement gives more than USD 10B regulatory AUM, illustrating why vintage matters. Check the original current ADV before updating the firm field. [FilingExplorer, undated](https://www.filingexplorer.com/investment-manager/altos-ventures-management-inc ); [official ADV PDF](https://reports.adviserinfo.sec.gov/reports/ADV/162777/PDF/162777.pdf ); [Airspace Link announcement, 2021-05-27](https://www.prnewswire.com/news-releases/airspace-link-completes-a-10-million-series-a-round-led-by-altos-ventures-301301078.html ).
**Current supported strategy:** initial investments in early-stage consumer and enterprise opportunities, followed by potentially significant commitments many years later. Official language does not publish a rigid pre-seed/seed/A/B mandate or firm check range. Historical transactions below demonstrate Series A and B participation; the broader snapshot contains later growth rounds, but those do not establish an unrestricted new-investment stage policy.

| **CryptoLab** | Official company confirms Altos participation in about **USD 16M Series A, July 2022**; history calls it **Series A-2**. Company-issued 2025 release gives original round as about **KRW 21B**.

Awair remains a baseline hardware lead: **Altos joined its USD 10M Series B on May 2, 2019**. It makes air-quality sensing devices; hardware alone does not establish frontier deep technology.

**Exclude TOLREMO from verified US Altos deep-tech evidence pending identity repair.** Its official CHF 9M Series A announcement, 2018-09-24, names **Swiss “Altos Venture”**, not the US firm. Bloomberg LEI identifies Altos Venture AG as a separate Allschwil Swiss entity; CB Insights' separate `altos-venture` profile attributes that exact transaction to the Swiss family office. The company is legitimately oncology/drug-resistance biotech, but affiliation is the issue. Existing Adex links and directories that pluralize its investor name should not override primary wording.

## Previous neurotech investments
**No verified neurotech investment found in the sources checked** for a direct neural-device, brain-computer-interface, neural measurement or proprietary neuromodulation technology developer. This is a search limitation, not a claim of zero investments.
**Amae Health is verified adjacent exposure:** Altos led its **USD 25M pre-empted Series B**, announced **2025-11-06**, and official Altos portfolio includes it. The financing supports an AI precision-care platform, academic-center partnerships and psychiatry-led outpatient care for severe mental illness. Current Amae website explicitly includes **transcranial magnetic stimulation (TMS)** in comprehensive care. Therefore describe it as a mental-health clinical-services investment with neuromodulation-treatment exposure; the sources do not establish Amae develops proprietary TMS hardware or neural interfaces. Its website states Amae Health, Inc. provides administrative/technology support while affiliated medical practices deliver clinical care. [Company-issued Business Wire release, 2025-11-06](https://www.businesswire.com/news/home/20251105989926/en/Amae-Health-Announces-%2425-Million-Series-B-to-Advance-Toward-a-Cure-for-Severe-Mental-Illness ); [Altos's own investment post, undated](https://www.linkedin.com/posts/altos-ventures_shining-a-spotlight-on-a-mission-driven-team-activity-7394389708035993600-10vk ); [Amae official website, undated](https://www.amaehealth.com/ ).
Syntekabio's AI/genomics and TOLREMO's oncology are not verified neurotechnology. Insight Timer and BrainCommerce names on the portfolio do not establish neural technology, and general AI portfolio companies were not reclassified as neurotech. Search combinations included Altos Ventures with neurotechnology, brain-computer, neuroscience and brain; similar results for **Alto Neuroscience** and **Altos Labs** were excluded as different identities. No partner's prior-firm investment was substituted for Altos attribution.
## Review notes for a later Adex updater
1. Replace undifferentiated “latest USD 500M November 2024” language with separately named Hybrid 6 (2024) and latest-known Korea Opportunity Fund 7 (2026). Preserve fully-sold filing dates and amounts, without asserting a ceremonial close date.
2. Resolve current AUM against the original Form ADV and retain its filing date; do not turn fund commitments, private-fund gross asset values or whole portfolio financing rounds into AUM/check sizes.
3. Investigate and likely remove/reassign TOLREMO/Tolremo participations from US Altos Ventures to the distinct Swiss investor after reviewing exact transaction entities.
4. Review Hodong Nam/Ho Nam for duplicate identity, “Han K” for legal name Han J. Kim, and board-role titles against firm roles. Do not automatically merge people solely on name resemblance.
5. Add/review evidence for CryptoLab (2022), UNASTELLA (2026), and Syntekabio (2016), which are stronger deep-tech examples than ordinary SaaS. Check Syntekabio date/stage conflicts before importing directory claims.
6. Keep Amae explicitly tagged mental-health services / TMS treatment exposure, unless a broader neurotech taxonomy intentionally includes clinical providers. No evidence found for direct neural-device development.
7. Treat Signal ranges as dated individual directory preferences; firm check fields remain unverified. This focused review does not exhaustively validate every inherited portfolio transaction or every possible newer vehicle.

## Summary
Altos Ventures is a Bay Area venture investor with an official strategy of entering early-stage consumer and enterprise companies and providing patient follow-on capital. Its holdings demonstrate credible deep-tech exposure in aerospace, cryptography and computational biotechnology, alongside a much larger software/consumer portfolio. The latest-known newly raised fund verified here is **Altos Korea Opportunity Fund 7, L.P., USD 350 million**, reported fully sold in April 2026. The baseline's USD 500 million figure belongs to **Altos Hybrid 6, L.P.**, already reported fully sold in October 2024. No verified neurotech investment found in the sources checked under a direct neural-device/brain-interface developer definition; Amae Health provides a relevant but distinct mental-health-services exposure, including delivery of TMS treatment. [Official strategy and portfolio](https://altos.vc/ ); [2026 SEC filing](https://www.sec.gov/Archives/edgar/data/2117687/000211768726000001/primary_doc.xml ); [2024 SEC filing](https://www.sec.gov/Archives/edgar/data/2019043/000201904324000001/primary_doc.xml ); [Amae website](https://www.amaehealth.com/ ).
## Starting Adex evidence
The raw exact-ID snapshot `data/research/_sources/AltosVentures.adex.json`, retrieved 2026-10-06, was read first. It identifies Altos Ventures Management, Inc.; its description claims 1996 founding, early-to-growth technology investing, a November 2024 USD 500 million latest fund and more than USD 8 billion regulatory AUM. The founding year is also stated in Airspace Link's company-issued 2021 financing announcement. The snapshot sources are altos.vc, NFX Signal and Goldilocks; this is inherited evidence, not independent verification. Firm investor-profile checkMin/checkMax/sweetSpot are all null. Roles include Hodong Nam and Ho Nam separately, Anthony P. Lee, “Han K,” Catherine Shin, Ram Gupta and Danielle Mastrangel Brown. Investments include Urban Sky, Airspace Link, Awair, TOLREMO/Tolremo and Amae Health, plus extensive SaaS/consumer holdings. [Airspace Link announcement, 2021-05-27](https://www.prnewswire.com/news-releases/airspace-link-completes-a-10-million-series-a-round-led-by-altos-ventures-301301078.html ).
Potential data issues: multiple duplicate/alias investments (e.g. TOLREMO/Tolremo, Clutch/WithClutch, Viva Republica variants); fields called `amount` often contain the whole financing amount, which is not evidence of Altos's check. The TOLREMO affiliation is particularly questionable (see below). Goldilocks currently labels a USD 11.2 million Syntekabio Series B as September 2025, while a contemporaneous Capital IQ report places it in May 2018: do not propagate its dating automatically. [Goldilocks, undated](https://goldi.ai/intelligence/vc/altos-ventures ); [Capital IQ report, published 2018-05-06, transaction 2018-05-07](https://www.marketscreener.com/quote/stock/SYNTEKABIO-INC-120976153/news/Syntekabio-Inc-announced-that-it-has-received-11-2-million-in-funding-from-Altos-Ventures-Smileg-34724868/ ).
## NFX Signal
[Signal firm page](https://signal.nfx.com/firms/altos-ventures ) was **directly read**, not only search-index accessible (undated). Public team profiles and preference tags were visible; introduction paths require Gmail login. The directory locates the firm in San Francisco/Menlo Park/Bay Area, whereas SEC fund addresses are Burlingame.
| Public Signal team listing | Individual sweet spot | Individual range | Relevant directory categories |
| --- | --- | --- | --- |
| Danielle Mastrangel Brown | USD 1M | USD 500K–1.5M | Pre-seed/seed; AI, medical devices, health IT, SaaS |
| Ram Gupta, advisor | USD 1M | USD 100K–10M | Seed/Series A; consumer, enterprise, fintech |
| Ho Nam, managing director | USD 5M | USD 500K–20M | Series A/B; AI, analytics, gaming, fintech |
| Catherine Shin, investor | USD 10M | USD 2M–20M | Seed/A/B; enterprise, AI, marketplaces, SaaS |
These are person-level directory preferences, not verified current employment or firm-level check policy. Medical-device and AI categories do not establish neurotech transactions. The 2026 fund SEC filing names Anthony P. Lee, Han J. Kim and Hodong Nam as managing directors of its general partner, providing better legal-name evidence than the incomplete Adex “Han K.” [Signal](https://signal.nfx.com/firms/altos-ventures ); [SEC XML, 2026-04-13](https://www.sec.gov/Archives/edgar/data/2117687/000211768726000001/primary_doc.xml ).

The baseline's November 2024 wording confuses reporting time with fund filing chronology: **Hybrid 6 reported USD 500M sold in October 2024; TechCrunch covered it November 12**.

AUM is unresolved and should be separately dated: the inherited USD 8B regulatory-AUM statement was not verified. FilingExplorer reports USD 5,448,790,139 discretionary AUM from a 2026-07-07 Form ADV. This is a **secondary transcription**, not adopted as independently verified current AUM; the official ADV PDF could not be parsed with available tools. A 2021 company announcement gives more than USD 10B regulatory AUM, illustrating why vintage matters. Check the original current ADV before updating the firm field.

**Current supported strategy:** initial investments in early-stage consumer and enterprise opportunities, followed by potentially significant commitments many years later. Official language does not publish a rigid pre-seed/seed/A/B mandate or firm check range. Historical transactions below demonstrate Series A and B participation; the broader snapshot contains later growth rounds, but those do not establish an unrestricted new-investment stage policy.
