No personal accounts are linked from Inworld's pages, so none are listed. The 28 October 2026 Reasoning post is signed by the Inworld TTS team. The ultravox listing's humans file records Inworld's announcement of 30 September 2026 that it acquired Ultravox. Investors come from the Series A release as published by Intel Capital and from The SaaS News report of the August 2023 round led by Lightspeed. Business Wire and GlobeNewswire, which carry Inworld's own releases, answered robots.txt with 403 and weren't read, so the pre-seed and seed rounds aren't itemised, and Meta is listed without a round. GamesBeat's report of 2 August 2023, read 6 November 2026, says the Lightspeed-led $50 million round brought the valuation to over $500 million and that Inworld had over $100 million in total funding; those are given as the valuation and total raised. It also quotes Michael Ermolenko as CTO and cofounder at the time. No later round was found.",
