100 Inc. review
CRM implementation, Onboarding, Migration · Setagaya-ku, Tokyo, Japan · Since 2018
Ownership. 100 Inc. is part of the WACUL group.
100 Inc., written in Japanese as kabushiki gaisha 100, was established on 14 February 2018 with capital of JPY 100 million and an office in Setagaya-ku, Tokyo. Its company page says it has been a HubSpot partner since 2012, before HubSpot had a Japanese entity, and lists TBS Holdings and WACUL as group companies.
The service map runs wider than most. Beyond hub implementation it covers data platform construction on BigQuery, Redshift, Snowflake and Databricks, BI reporting through Looker, Tableau, Power BI and QuickSight, single sign-on with Okta, OneLogin, TrustLogin and Microsoft Entra ID, and migration from Salesforce Sales Cloud, Marketing Cloud, Pardot, Marketo, Kintone and Zendesk.
The published case studies are Japanese industrial and technology names, including Panasonic Industry, Yamaha Robotics, JFE Systems and e-dash. It holds ISO/IEC 27001:2022 and ISO 9001:2015, the HubSpot Onboarding Accreditation, and says it runs the Japan HubSpot User Group.
Who 100 Inc. is for
Japanese enterprises, particularly manufacturers and technology companies, replacing Salesforce, Pardot or Marketo and needing the result to talk to a data warehouse and a BI layer. The named integration list is long and specific, down to Sansan DataHub, CData, TROCCO, Fivetran and Xactly Forecasting.
Organisations that want the marketing operation run as well as built are also catered for, since the service map carries inside sales, telemarketing, webinar operations and exhibition support as business process outsourcing alongside the platform work.
Strengths and limits
Strengths
- Names every integration and migration source individually, from SAP and Kintone through to electronic contract systems such as CloudSign and DocuSign
- Publishes fixed prices for its five Content Hub website template packages, from JPY 350,000 to JPY 2,200,000 excluding tax
- Holds ISO/IEC 27001:2022 and ISO 9001:2015 with certificate numbers listed, alongside the HubSpot Onboarding Accreditation
- Case studies are named Japanese enterprises rather than anonymised logos, including Panasonic Industry, Yamaha Robotics and JFE Systems
Limits
- Headcount is not published anywhere on the site
- Implementation and RevOps work carries no published price, only the website template packages do
- The site is Japanese first and the English section is much thinner, so a non-Japanese buyer will be reading a translation
- Code ownership, documentation handover and the HubSpot licence question are all absent from the site
100 Inc. pricing
The only published prices sit on the website template page and cover Content Hub builds. The contact and document download module is JPY 350,000, the event package and the owned media package are JPY 870,000 each, the blog package is JPY 1,600,000 and the full B2B site plan is JPY 2,200,000, all excluding tax and all including installation, limited customisation and a one hour onboarding session.
The same page resells WACUL's AI Analyst tool with consultant support from JPY 100,000 a month excluding tax, a JPY 100,000 initial fee and a minimum contract from twelve months. The enquiry form asks for an annual budget on a scale running from under JPY 500,000 to over JPY 30 million, which is the clearest signal of the range it works across.
Prices are published for the Content Hub website template packages only, excluding tax: JPY 350,000 for the contact and document download module, JPY 870,000 for the event or owned media modules, JPY 1,600,000 for the blog package and JPY 2,200,000 for the full B2B site plan. Implementation services are quoted.
Licences, the build, and whose hands
Does it earn on your licences
Does not say whether it earns on your licences
We found nothing on its site or in its terms about whether it resells HubSpot licences or is paid on the software it recommends. That is recorded as silence, not as a finding against the firm. Ask before the first invoice.
Who owns the build
Does not say who owns the build
We found nothing on its site or in its terms about who keeps the portal, the workflows and any custom code when the engagement ends. That is recorded as silence, not as a finding against the firm. Ask before the first invoice.
Who does the work
Does not say who does the work
We found nothing on its site or in its terms about whether the people in your portal are employees, an offshore team or subcontractors. That is recorded as silence, not as a finding against the firm. Ask before the first invoice.
This records what 100 Inc. publishes about itself, read in September 2026. It is not an assessment of what the firm does in practice.
Verdict
Enterprises in Japan moving off Salesforce, Pardot or Marketo, where the CRM has to feed a warehouse and a BI stack, are the reader this practice is written for. The integration list is specific enough to check against your own systems before you make contact, and the case studies name real industrial companies.
Buyers outside Japan will find the English section thin against the Japanese one, and the published prices cover website template packages rather than the CRM work itself. Headcount, code ownership and the licence question are all absent, so each has to be raised directly.
