EnglishCentral, Inc. is an eighteen-year-old Delaware C-corp selling AI-powered English tutoring. It tells the world it has 10 million learners, 400 schools, and eight patents. The open record tells a different story — one where the patents are trademarks, the IP is someone else's open-source code, the Japanese operating entity was insolvent in 2020, and the equity has quietly migrated from California venture capital to a Japanese printing conglomerate.
The public-facing version of EnglishCentral as of April 2026, assembled from the company's own materials, its press releases, and the third-party estimators that private-company investors most often cite.
The pitch repeats across partner press releases, the company's own site, and LinkedIn job listings. Ten million learners. Four hundred schools. The "IntelliSpeech℠" speech engine. Partnerships with NTT, DOCOMO, SK Telecom, Kirihara Shoten, TOPPAN subsidiaries, and — in Brazil — the Paraná state government. Eighteen years private, no published exit.
The founder and CEO, Alan Schwartz, has a plausible résumé: Princeton BA, Harvard Law (International Legal Studies, 1993, never practiced), AT&T Bell Labs, SpeechWorks VP International, Nuance VP/GM Asia-Pacific & Japan (Tokyo, 2005–2007). The company was funded by Google Ventures in 2009, then by Atlas Venture, NTT, DOCOMO, SK Telecom, Stonebridge, and KLab/Hitomedia over the following decade. It is now in year eighteen.
This report is about the gap between that pitch and what the records show when you pull them.
EnglishCentral is a private company. It has no SEC financial filings beyond a single 2009 Form D. But its Japanese operating entities are subject to Japan's mandatory 決算公告 (kessan-kōkoku) statute — which means the balance sheets are in Kanpō. Building up from those, plus the published unit economics of EC's largest Japanese customer, lets us bracket the real revenue without relying on any estimator.
EnglishCentral's largest named Japanese customer relationship is with Kirihara Shoten, the 130-year-old Tokyo publisher whose "Kirihara Online Academy" platform bundles EC for high schools. The public pricing: ¥1,650 per student (roughly $11) for a one-year license, sold to ~400 Japanese high schools totaling ~60,000 students.
If EC keeps half the license revenue, Japan school revenue is:
Even with a generous 100% share assumption the number caps at ~$650K. Add the smaller Japanese B2C tier (the consumer website is lightly trafficked in Japan) and the Japan segment lands in the $3M–$5M all-in range, including B2C, B2B partnerships with Tosho/TOPPAN, and the Langrich consumer tutoring service.

Japan's 会社法第440条 (Companies Act Art. 440) requires every joint-stock company to publish a balance-sheet summary each year in 官報 (Kanpō, the official gazette). Those filings are indexed on catr.jp. We pulled all four for the Tosho/EC joint-venture entity (hojin-bangō 6010501047896, ELLS K.K.):
| Fiscal year | Total assets | Net income | Notes |
|---|---|---|---|
| FY2021 (1期) | ¥159M ($1.06M) | +¥12M | First year post-incorporation |
| FY2022 (2期) | ¥152M ($1.01M) | +¥18M | Peak |
| FY2023 (3期) | ¥124M ($830K) | ▲¥17.5M | Swings to loss |
| FY2024 (4期) | ¥117M ($780K) | +¥2.4M | Schwartz becomes 代表取締役 |
Four years. Total net income: roughly $100K cumulative. Total assets now sit at $780K against a public target (Nikkei, Oct 2021) of ¥2 billion in revenue by year five. A company expecting to do ¥2B in revenue does not operate off a ¥117M balance sheet.

Before the 2021 JV, EC operated in Japan through a separate 2009-incorporated subsidiary — 株式会社EnglishCentral (hojin-bangō 8010401084055). Its FY2020 第12期 balance sheet, also in Kanpō:
| Line | Amount |
|---|---|
| Total assets | ¥302M |
| Total liabilities | ¥482M |
| Retained earnings | ▲¥182M |
| Equity position | Negative ¥180M — technically insolvent |
Assets less than liabilities. Retained earnings of negative ¥182M accumulated over twelve years. The entity was wound down, and operations shifted into the thinly-capitalized Tosho JV the following year. The JV vehicle has never held the asset base necessary to support the revenue scale implied by "10 million users."
A fair objection: if the JV is structured as a cost-plus / profit-stripping entity that pays 100% of net income upward to TOPPAN and EnglishCentral each year — via dividends, licensing fees, or management fees — then a flat ¥117M balance sheet and near-zero retained earnings are fully consistent with any revenue scale. The 決算公告 statute requires only the balance sheet, so dividends and transfer payments are not in the data we have.
The argument has force. Three things to weigh against it:
Conclusion: the steel-man is logically possible but requires unseen revenue to land somewhere that would normally leave a trace in a consolidated parent's filings, and that trace is absent.
SBA's Paycheck Protection Program loan-level public dataset contains one loan to EnglishCentral:
In May 2020 EnglishCentral, Inc. told the Small Business Administration it had five US employees. The loan was for payroll only, fully forgiven, through Bank of America. The address on the filing — 150 District Avenue, Burlington MA — is a Regus coworking location. NAICS code 541512 (Computer Systems Design). Business age: "New Business or 2 years or less" — despite incorporation in 2008.

EnglishCentral's most-repeated technical claim is its "proprietary" IntelliSpeech speech-recognition platform and an "8 patent" portfolio. The patent offices disagree.
Japan's gBizINFO IP register indexes every Japanese patent, design, and trademark by corporate number. For EnglishCentral's Japanese entity (8010401084055):
| Rights type | Count |
|---|---|
| 特許 (Patents) | 0 |
| 意匠 (Designs) | 0 |
| 商標 (Trademarks) | 8 |
The "8 patents" in marketing materials are eight trademark registrations — word and logo marks across Nice classes 9 (software), 16 (printed matter), 28 (toys/games), 35 (advertising), 38 (telecom), 39 (transport), 41 (education), and 42 (tech services). Trademarks and patents are categorically different intellectual-property rights; the conflation in public materials is consistent and systematic.

USPTO full-text search surfaces exactly one EnglishCentral-assigned filing: application US20120164612A1, "Language Learning Using Text-to-Speech Synthesis," filed December 2011. Status: abandoned September 2018. Five co-inventors, all alumni of SpeechWorks/Nuance — Schwartz's prior employers. Never granted. Never extended.

The service-mark designation ℠ — the symbol EnglishCentral uses next to "IntelliSpeech" — is an unregistered claim. It requires no examination, no filing, and no defensible right. In Justia's US trademark register, the mark INTELLISPEECH® (registered) is owned not by EnglishCentral but by Bongiovi Medical / Amcom Software, in the medical-audio category.
If EnglishCentral tried to assert the name in US commerce, a Bongiovi cease-and-desist on priority grounds is a plausible outcome.

EC's Chief Scientist since 2014 is Nickolay Shmyrev (Astrakhan, Russia). Shmyrev simultaneously runs his own company, Alpha Cephei, and is the maintainer and CEO of Vosk — one of the most-starred open-source speech-recognition toolkits in the world (14,500+ GitHub stars, Apache 2.0 license, freely available to anyone).
EnglishCentral's own source code, inspectable in the public JavaScript bundle served from its website, shows the speech pipeline configuration:
The "proprietary" IntelliSpeech engine is Vosk, wrapped. Both the primary (Vosk, open-source) and fallback (OpenAI Whisper, commodity API) are third-party. There is nothing in the stack that couldn't be rebuilt by a competent engineer in a weekend.

The talent layer that gave EC's speech claim any substance in 2009–2013 was poached by consumer-electronics majors starting in 2013. What replaced it is an open-source maintainer with a dual-hatted side company and a pipeline of commodity APIs.

Over the last five years, EnglishCentral's operating, legal, and executive weight has moved out of Delaware and into Tokyo — and out of the original 2009 subsidiary into a new TOPPAN-partnered joint venture.
Aside from Schwartz — who appears to have moved to Japan — the US side of EnglishCentral is a Regus office in Burlington, MA; a Delaware C-corp with no filings beyond the 2009 Form D; and five employees on the 2020 PPP loan. Delaware maintains the entity. Delaware does not operate it.
The US venture investors who led the 2009 Series A are still carrying EnglishCentral on their books. They do not sit on the board. They have not published exits. In a seventeen-year private hold, that combination is unusual.
As of April 2026, gv.com/portfolio lists "English Central" without the asterisk GV uses to denote acquired / exited positions. GV funds from 2009 vintage would typically be in their 13th year of a 10-year fund lifecycle, past the usual extension. GV has neither written the position down publicly nor exited it. Rich Miner's departure from the EC board tracks his 2016 exit from GV itself to run Google's education initiatives.
Atlas Venture's Boston (tech) arm spun out as Accomplice in 2015; Axel Bichara (EC's Series A lead) spun again into Baukunst and Bolt. Accomplice still carries the historic Atlas Venture Fund VIII tail positions. There is no public secondary transaction for EC shares. The position is long-dated, non-cash, and functionally inert on the cap table.
A connecting detail: Bolt (Bichara's current vehicle) has invested in Sense Labs, founded by Mike Phillips — the SpeechWorks co-founder who still sits on EC's board. The same small cluster of 2000s-era Boston speech-tech principals has been in each other's companies for two decades. The circle closes.
NTT-IP ($1M, 2010), DOCOMO Capital, and SKT Ventures all invested at early stages. None sit on the board as of 2026. None have published write-downs or write-ups. DOCOMO Capital's address in US securities filings (per NTT DOCOMO's 20-F and InvenSense S-1 Exhibit 4.2): 3240 Hillview Avenue, Palo Alto CA. SK Telecom Ventures LLC: 2460 Sand Hill Road, Menlo Park CA.
Both entities are US corporations. The relevance of that fact is in the next section.
Kirihara's own Kanpō-filed balance sheets (also on catr.jp) show significant recent losses: FY ending March 2025 posted a positive ¥100M; the six-month period ending September 2025 posted a ▲¥292M loss and a 27% drop in total assets. Kirihara is the only EC equity-holding Japanese partner whose financials have been forced into the open by statute, and the company that distributes EnglishCentral to 400 Japanese high schools is in decline. Kirihara was acquired by Gakken Holdings in September 2024.
Gakken Holdings (TSE: 9470) holds:
Gakken's published Gakken2025 mid-term plan designated language-learning as a priority before the Kirihara acquisition and the Progos-EC partnership. The two Japanese counterparties EnglishCentral leans on hardest are now under common control. Gakken sits on both sides of the EC-Progos TestCentral partnership and on the schools side through Kirihara. Neither fact is disclosed in EC's partner communications.
The items below are individually legal, collectively unusual, and together describe a company whose public posture and actual operations have drifted apart.
SEC Regulation S, Rule 902(k)(1), defines U.S. person broadly. A corporation or partnership organized under the laws of the United States is a U.S. person, even if its ultimate beneficial owner is foreign. Offshore securities offerings exempt under Reg S may not be sold to U.S. persons.
DOCOMO Capital Inc. is a Delaware corporation with a Palo Alto office (verified via multiple S-1 and 20-F filings, including NTT DOCOMO's own Form 20-F). SK Telecom Ventures LLC is a Delaware LLC with a Menlo Park office (verified via the SIM OPS STUDIOS Form D). Both are U.S. persons for Reg S purposes.
EnglishCentral's only SEC filing is the 2009 Form D. It has not filed any further Form D for any subsequent financing round. If DOCOMO Capital Inc. or SK Telecom Ventures LLC invested in post-2009 rounds without that round being registered or filed under Reg D, the issuer may have a Reg D Form D filing gap. Full-text EDGAR search across every Form D returns zero filings mentioning "DOCOMO Capital" as an investor — the entity is entirely absent from Form D disclosures even though its 2009 address appears in InvenSense's S-1 exhibit.
This is a securities-law question raised by the record, not a determination. Establishing violation would require confirmation of the investment dates and the exemption relied on.
LinkedIn self-reports 501–1,000 employees for EnglishCentral. The actual LinkedIn-discoverable count under the main company page is 219. A separate "EnglishCentral Teachers" page carries another 109 (Philippines-based tutors, the Langrich residual). The 2020 SBA PPP filing: 5 US employees. Glassdoor describes Philippines tutor wages at PHP 120–150 per day (roughly US $2–3). Built In shows zero open US positions.
The 501–1,000 self-report is what populates the employee counts on LinkedIn-scraping databases; the 219 + 109 Philippines tutor reality is what's discoverable by head-counting individual profiles. A buyer doing diligence off the former will be modeling a very different company than one doing diligence off the latter.
The "10 million learners" figure has been in use since at least 2019. Sensor-tower-adjacent estimates place current monthly active users in the 200,000–400,000 range. Google Play lifetime installs: 3.7M (not unique users; installs). Apple App Store all-time ratings: 1,457. Twitter followers: 4,486. Instagram followers: 501K (anomalously high given other metrics — likely inflated).
Nikkei's October 2021 coverage of the Tosho/EC JV formation: "凸版系、英語学習の新会社設立 5年後に売上高20億円" — ¥2 billion in revenue, five years out. Year four actual total assets: ¥117M. The company would need to grow total assets seventeen-fold and convert almost all of them into annual revenue to hit its own stated target. Neither metric is trending in that direction.
Alan Schwartz is not a SpeechWorks co-founder. He joined SpeechWorks in July 2000 as VP Business Development, became VP International, and moved to Nuance when it acquired SpeechWorks in 2003. Nuance Asia-Pacific & Japan in Tokyo (2005–2007) gave him both the Japan network and the speech-industry talent pipeline that would later populate EC. The 2009 Form D lists him as President / CEO — not as prior founder. This is a smaller point than the others, but it is part of the same pattern: the public biography is presented more heroically than the paper trail supports.
Delaware incorporation. US VC on the cap table. Japanese operating entity insolvent in 2020. Replacement JV thinly capitalized in 2021. Founder becomes Representative Director of that JV. Corporate pivot toward Japanese HR / corporate-testing. No IPO, no M&A, no published secondary. GV still carries the position. The venture capital that funded the Delaware entity has financed the slow construction of a Japan-centered operation controlled by a Japanese printing conglomerate's spin-off JV and a Japanese publishing conglomerate's subsidiary.
At some point the question investors and regulators should ask stops being "what is the revenue" and becomes "whose company is this, and which jurisdiction would a claim be filed in."
The items below are material, public, and visible only if one reads Japanese public-records databases:
Japanese public disclosure is thorough. It is also published almost entirely in Japanese. A US private-company investor without Japan-language diligence capacity would not surface any of the above. Each is mandatory under Japanese law and immediately verifiable.
Every claim above is cited to a specific public record. Below is the map of which kind of record answered which question.

Every number in this report comes from a filing, a registry, a dataset, or a direct statement by a primary source. Third-party estimators (Prospeo, ZoomInfo, SignalHire, CBInsights) were explicitly excluded from the revenue reconstruction — those are model outputs, not company disclosures, and treating them as such would be unfair to the company. The revenue range given here is bracketed bottom-up from Japanese statutory filings and published unit pricing.
The core technique: cross-jurisdiction reconciliation. When a US-domiciled private company's Japanese operating entity is subject to Japanese mandatory statutory disclosure, the US investor-facing narrative can be stress-tested against the Japanese filings. That is the gap this report lives in.
Standard: two-source rule. No claim above rests on a single dataset. Where a finding is unique to one source, that fact is flagged.
Each of those would tighten the picture. None would materially change it.
This profile is drawn from public records. It does not assert fraud, deception, or criminality; those are determinations for courts and regulators. It describes gaps between the company's own public claims and what the public record shows — gaps that any investor, regulator, or student of private-company structuring should be aware of.
The subject — Alan Schwartz, EnglishCentral, Inc., its counterparties, and its investors — is invited to supply any public records that rebut or contextualise any factual claim above. Corrections will be integrated into future versions of this report.
