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.
Funds and investment stages
| Vehicle / metric | Supported amount and status | Timing and interpretation |
| --- | --- | --- |
| Humba II | **USD 40m**, described by the firm as oversubscribed second fund; completed fundraising announcement | December 12, 2024. The announcement explicitly supports pre-seed USD 250k–500k and seed USD 500k–1m checks. Latest-known publicly announced completed fund, not an assertion that no newer close exists. [S3] |
| Humba III, L.P. | Offering size **indefinite**; **USD 0 sold**, zero investors, first sale yet to occur in the notice | July 13, 2026 SEC Form D. Related persons include Humba Ventures Management, LLC and Leo Polovets; Delaware entity formed 2026. This is a newer vehicle/offer, not a target amount or closed fund. No later completed-close announcement was found in the searches performed. [S4] |
| Humba I | **USD 8m reported by a secondary filing aggregator**, not verified here as a final fund close | Aggregator gives December 2021; SEC index shows a Form D filed January 7, 2022. The underlying Form D was inaccessible through the browser, so retain as a review lead rather than a verified amount. [S11, S12] |
| Current typical check | **USD 750k–1.5m** | Undated current official homepage, accessed October 6, 2026. This differs from the 2024 stage-specific ranges; present it with its source date rather than silently replacing every historical range. [S5] |
No verified standalone Humba total AUM figure was found. Susa AUM, fund commitments, per-company checks and total company funding are different quantities.
The 2024 fund announcement explicitly supports a **pre-seed and seed** mandate, with physical-economy sectors including transportation, energy, industry, healthcare and national security. The July 12, 2022 launch was broader: a Susa-managed scout/supportive investment fund, stage-flexible and writing USD 100k–500k checks. The historic flexibility should not substitute for today's deep-tech focus. [S3, S13]

Match research 2026-10-06 / HumbaVentures / sha256:5ca8db3b97ef7b72a6e2b847028962542b9142006d604898b150479d97ac4386 / part 2 of 2
Imported completed research. Baseline Adex/Signal statements describe prior state, not independent verification. Retain cited attribution, date, currency and classification caveats.
1. Add source-backed **pre-seed and seed** mandate, with the historic broader 2022 strategy preserved as dated context. [S3, S13]
2. Add **Humba II USD 40m, announcement December 12, 2024**, marked completed fund. Record Humba III only as a July 2026 offering lead with unknown final size/status; check for subsequent SEC amendments or an official close before upgrading it. [S3, S4]
3. Fill current typical check range from the homepage, **USD 750k–1.5m**, with an October 6, 2026 access date. Preserve older stage-specific figures separately. Do not import Signal's USD 90m profile field or Susa AUM. [S2, S3, S5]
4. Replace generic portfolio-only evidence with selected dated transactions above where appropriate. Distinguish Hexium equity/debt, Mytra first-round attribution from later company funding, and company round totals from Humba's unknown check amounts.
5. Review the 28 unnamed records without inventing names; add the brain-surgery description only as firm-reported unnamed evidence. No verified named neurotech classification is presently supported.
6. Founding date remains nuanced: Signal gives 2021 experience, official public launch was July 2022, and first-fund filings predate launch. Avoid inventing a precise founding date. Current team evidence supports Leo and Anna-Sofia; the reviewed material is not a comprehensive legal personnel roster. [S2, S13]

# Humba Ventures
- Exact Adex ID: `HumbaVentures`
- Canonical Adex URL: https://adex.page/firms/HumbaVentures
- Research date and source access date: **2026-10-06**
- Research only: no Adex or database changes made.
Humba is a Susa-family early-stage investor whose present mandate emphasizes deep technology and strategically important industries. **Latest-known publicly announced completed fund: Humba II, USD 40 million, announced December 12, 2024.** A newer **Humba III** SEC offering notice exists, dated July 13, 2026, but it reports an indefinite offering and USD 0 sold; it is not evidence of a completed third fund. Named investments establish substantial deep-tech activity. No named neurotechnology investment was verified; there is a firm-reported unnamed brain-surgery investment that deserves follow-up. [S3, S4, S6–S10]
## Adex starting evidence
The exact-ID snapshot at `data/research/_sources/HumbaVentures.adex.json`, retrieved October 6, 2026 through read-only MCP Search, contains Humba Ventures, investor ID 6074. Its description calls it a seed investor in manufacturing, robotics, chips, biotechnology, climate, energy, defense, aerospace and hardware. It names Leo Polovets (General Partner) and Anna-Sofia Lesiv (Investor and Writer), has null founding date and null check minimum, maximum and sweet spot, and gives San Francisco as location. Sources point to the homepage and Signal, based on a September 14, 2026 research import.
The baseline contains **65 investment participations: 37 named companies and 28 unnamed placeholders**. These are homepage portfolio claims with unknown stages, dates and amounts; `isLead: false` is not affirmative evidence of non-lead participation. Named examples include Antares, Mytra, Hexium, Parallel Bio, Windborne, Swarm Aero, Northwood Space, Jacobi Robotics, Treeswift and Adaptyx. The baseline alone does not establish particular funding rounds. The unnamed placeholders must not be treated as resolved company identities.
## NFX Signal inspection and limitations
The [firm page](https://signal.nfx.com/firms/humba-ventures ) was directly read. Its accessible text contained the firm name and a team heading, but no substantive team, fund or stage details. [S1]
The related [Leo Polovets profile](https://signal.nfx.com/investors/leo-polovets ) was directly read. It lists Humba GP experience from 2021, seed/pre-seed sector rankings, a USD 250,000–1 million range, USD 750,000 sweet spot and USD 90 million current fund. However, the displayed current investing position is **Susa Ventures**, and the profile mixes Susa, Humba and personal history. The USD 90 million must not be transferred to Humba. Search-index snippets additionally surfaced Parallel Bio seed December 2022 and Mytra seed July 2022, while the direct page gated the full investment list behind sign-in. These transaction snippets are leads, not independent firm attribution or exact round verification. [S2]
## Funds and investment stages
| Vehicle / metric | Supported amount and status | Timing and interpretation |
| --- | --- | --- |
| Humba II | **USD 40m**, described by the firm as oversubscribed second fund; completed fundraising announcement | December 12, 2024. The announcement explicitly supports pre-seed USD 250k–500k and seed USD 500k–1m checks. Latest-known publicly announced completed fund, not an assertion that no newer close exists. [S3] |
| Humba III, L.P. | Offering size **indefinite**; **USD 0 sold**, zero investors, first sale yet to occur in the notice | July 13, 2026 SEC Form D. Related persons include Humba Ventures Management, LLC and Leo Polovets; Delaware entity formed 2026. This is a newer vehicle/offer, not a target amount or closed fund. No later completed-close announcement was found in the searches performed. [S4] |
| Humba I | **USD 8m reported by a secondary filing aggregator**, not verified here as a final fund close | Aggregator gives December 2021; SEC index shows a Form D filed January 7, 2022. The underlying Form D was inaccessible through the browser, so retain as a review lead rather than a verified amount. [S11, S12] |
| Current typical check | **USD 750k–1.5m** | Undated current official homepage, accessed October 6, 2026. This differs from the 2024 stage-specific ranges; present it with its source date rather than silently replacing every historical range. [S5] |
No verified standalone Humba total AUM figure was found. Susa AUM, fund commitments, per-company checks and total company funding are different quantities.
The 2024 fund announcement explicitly supports a **pre-seed and seed** mandate, with physical-economy sectors including transportation, energy, industry, healthcare and national security. The July 12, 2022 launch was broader: a Susa-managed scout/supportive investment fund, stage-flexible and writing USD 100k–500k checks. The historic flexibility should not substitute for today's deep-tech focus. [S3, S13]
## Previous deep-tech investments
These examples combine firm attribution with technology or transaction evidence. Round amounts are company raises, not Humba's individual checks.
| Company | Technology rationale and attribution | Supported round/date and limits |
| --- | --- | --- |
| **Hexium** | Laser isotope separation for enriched lithium nuclear fuels. Humba's detailed company article explicitly says its first checks arrived in May 2024; Hexium's official press page links that article. [S6, S7] | Earliest checks **May 2024**, amount/stage unspecified. April 15, 2025 reporting identifies Humba participation in seed financing; the company's press page links that report. Preserve **USD 9.5m equity + USD 2.5m credit** separately; do not call the whole USD 12m equity. [S6–S8] |
| **Antares** | Nuclear microreactors for military, remote and space uses. Transaction counsel names Susa/Humba in the financing, and Humba's fund announcement independently identifies it as a seeded portfolio company. [S3, S9] | **USD 8m seed**, counsel announcement November 1, 2023. Individual Humba check and precise closing date not disclosed. [S9] |
| **Mytra** | Autonomous robotic storage and movement of warehouse materials; integration of mechanical, electrical and software systems. Humba's GP confirms investment in its first round. [S10] | Article July 29, 2024 recalls meeting the founder about two years earlier and distinguishes initial investment from subsequent almost USD 80m Series A/B funding. Exact first-round amount/date not verified; do not import Signal's July 2022 date as established fact. [S2, S10] |
| **Parallel Bio** | Human lymph-node organoids combined with AI and robotics for drug evaluation; biologically engineered experimental systems, rather than ordinary SaaS. Company-issued release explicitly names Humba among existing investors in the new round. [S14] | **USD 21m Series A**, June 12, 2025, led by AIX Ventures. Humba is a participating existing investor; its check is undisclosed. This is immune-system biotech, **not evidence of neural organoids or neurotech**. [S14, S15] |
| **WindBorne Systems** | Balloon sensor networks providing atmospheric data for weather/climate prediction. A Susa-published investment announcement explicitly attributes the investment to Humba. [S16] | **USD 6m seed**, announced June 22, 2023, led by Footwork. Individual Humba amount undisclosed. [S16] |
Other named homepage investments can guide additional company-level verification. Do not automatically classify every entry as deep tech: software-only education, workflow or administrative products require a specific scientific/engineering rationale. Team prior-fund/angel investments must remain separate from Humba portfolio attribution. [S5]
## Neurotechnology findings
**No verified neurotech investment found in the sources checked.** This means no named company with independently supported Humba attribution and direct neural/brain technology was established, not that Humba has made no such investments.
The official portfolio includes an unnamed company developing **MRI-guided high-precision brain surgery**. This is credible firm-reported exposure to brain-directed surgical technology, but its company name, investment date, amount and round remain unknown. Keep it as an unnamed claim pending corroboration; do not guess a company from a similar product description or equate general MRI technology with a BCI. [S5]
Searches checked Humba combined with brain surgery, MRI, neurotechnology, neural and BCI, along with its official portfolio, relevant investor profile and named biotech examples. General organoid biotech, oncology, ophthalmology, telehealth and AI alone do not verify neurotech exposure.
