The short version

Sequant is a sponsor group of 2 issuers that PartnerFacts links to one sponsor (shared people, shared management entity; automatic match from the filings), filing 3 Form D filings between Mar 2021 and Mar 2022.

What this means One team, 2 deal companies, about 1 year of track record in SEC filings. We link the companies because the same people or address appear on their forms — tap "Request a correction" if that is wrong.

Combined reported sold: $7.59M to 7 investors (latest filing per issuer). Industries as reported: Pooled Investment Fund (2). Issuers are based in CA (2).

What this means $7.59M raised across the group, about $1.08M per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: Igor Shestopalov (2 issuers, executive officer and director), SeQuant Capital LLC (2 issuers, executive officer, entity) and Sergei Chmel (2 issuers, executive officer and director).

What this means The person on the most companies is usually the one running the show; their page lists every deal.

Activity: 0 new offerings in the last 12 months; latest filing Mar 17, 2022.

What this means No new raise filed in the past year.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA), property records (NYC, FL, IL and TX counties) — none found.

What this means Nothing turned up where we looked (4 sources). That does not prove there is nothing — it means none was found in those sources on that date.

We compared 3 public filings for Sequant and found 2 differences: No amendment in the last 12 months on an offering that may still be open; Address moved from La Jolla, CA to San Marcos, CA.

What this means These are differences between the sponsor's own SEC filings — both values, dates and sources are listed in Key records, section 4. Most have ordinary explanations; ask the sponsor.

Key records

Five things investors ask first. Items still in human review are counted, not shown.

1. Lawsuits

None found in sources searched — federal courts (CourtListener / RECAP), checked Oct 24, 2026

What was searched

Sources searched: CourtListener bulk data (RECAP dockets as of 2026-09-30; recall-first rule 10-24) — federal district + bankruptcy courts State courts: not covered (one-tap state court links under Look further). PACER: not searched. · Last checked Oct 24, 2026, 2:16 AM ET.

State courts: not covered (one-tap state court links under Look further). No state offers a lawful automated statewide source PartnerFacts can use today. Texas (re:SearchTX) terms prohibit storing results in a database open to third parties; New York (WebCivil) and Massachusetts (MassCourts) require a browser check that blocks scripted queries; California has no statewide index (58 county portals; Rule of Court 2.503 grants name-based access case by case); Florida, Utah and Illinois offer paid or partial access whose terms for automated use are unverified. Washington (dw.courts.wa.gov; bulk index reports under a JISC data-dissemination agreement), Delaware (CourtConnect; Court of Chancery not included) and Arizona (apps.azcourts.gov/publicaccess, which has an official channel to request high-volume access) are the candidates; PartnerFacts will request written permission before any automated search. Federal courts are searched through CourtListener / RECAP.

2. Regulatory actions

None found in sources searched — SEC enforcement releases (index scan as of Oct 24, 2026, 2:50 AM ET) · state securities regulators: AZ, CA, DE, TX, WA (crawled Oct 23, 2026)

What was searched

SEC enforcement searched: SEC litigation releases and administrative proceedings — respondent names in the sec.gov index titles (30,205 releases, 1995-09-19 to 2026-10-23); release text is read only to confirm a candidate. Names that appear only in the body of a release are not found. — Searched SEC litigation releases and administrative proceedings (1995→ / 2007→) (30,205 records as of Oct 24, 2026, 2:50 AM ET) — nothing matched Sequant..

State securities regulators searched: AZ (Corporation Commission Securities Division), CA (DFPI — 16 of 12,159 DFPI respondent pages read so far; sponsor-name matches are read first), DE (DOJ Investor Protection Unit), TX (State Securities Board), WA (DFI) — last crawled Oct 23, 2026, 9:57 PM ET. Other states are not covered.

3. Bankruptcies

None found in sources searched — federal bankruptcy courts (CourtListener / RECAP), checked Oct 24, 2026

What was searched

Sources searched: Federal bankruptcy courts via CourtListener / RECAP archive (federal district courts, federal bankruptcy courts). State courts: not covered (one-tap state court links under Look further). PACER: not searched (RECAP only). · Last checked Oct 24, 2026, 2:16 AM ET.

4. Differences between public sources

No comparisons published

What is compared

No public statement by this sponsor group has been collected yet, so there is nothing to compare. Sources compared: the sponsor's own website (known from the issuer's own filings — Form C issuer website, EDGAR company profile — an approved profile claim or Form ADV Item 1.I of its matched adviser) · SEC Form D · SEC Form ADV (IAPD) · Internet Archive · No website is on file for this sponsor group yet.

2 differences found between the filings for Sequant (compared 3 filings on Oct 24, 2026)

Note · May 14, 2021 – Mar 17, 2022

No amendment in the last 12 months on an offering that may still be open — BTC Arbitrage SP (latest filing Mar 17, 2022)

The latest filing for this offering is dated Mar 17, 2022 (first sale May 14, 2021). It reports $7,585,200 sold of an indefinite amount offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

Note · Mar 16, 2021 – Mar 17, 2022

Address moved from La Jolla, CA to San Marcos, CA — BTC Arbitrage SP

The people listed on the Mar 16, 2021 filing give La Jolla, CA; on the Mar 17, 2022 filing they give San Marcos, CA.

What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.

What is compared

What is compared: every Form D and D/A we hold for this subject, side by side — filing dates vs. first-sale dates (the 15-day rule), amendment timing on open offerings (the yearly-amendment expectation), amounts sold, investor counts, offering amounts and minimums across amendments, industry and size bands, addresses, how each person's name and role is written, paid sellers' CRD numbers, and (for groups) where the member companies were formed and sit. Everything is as filed by the issuer; the SEC does not check it. Differences are common and usually have ordinary explanations — we show both values, the dates, and the source so you can ask. As of Oct 24, 2026.

5. Money to insiders

None reported on 2 offerings — no sales commissions, finder's fees or proceeds to insiders

Counts come from Form D Items 12–15 on the filings in our index (latest filing per offering; one offering = one SEC file number; an amendment updates its offering rather than adding one). "To insiders" = gross proceeds used for payments to executive officers, directors or promoters. "—" = not reported on that filing. Amounts marked (est.) were reported as estimates. "Paid to sell it" = sales compensation recipients named on that filing (Item 12), each linked to FINRA BrokerCheck when a CRD number is reported.
