Roman Yanushevskyi
Roman Yanushevskyi is a Ukrainian competitive programmer and founder. He won gold at the International Olympiad in Informatics 2022 for Ukraine, placing 7th worldwide. He studied Theoretical Computer Science at Jagiellonian University, then Mathematics and Computer Science at the National University of Singapore, and competed for NUS at the ICPC 2025 World Finals. He held two quantitative research internships at Citadel Securities (2024, 2025) and an AI engineering role at Lovable building GPTEngineer.app, before co-founding Touchmark (Y Combinator Summer 2026), a market for future AI inference capacity, with Ilia Bolgov.
- Quant employment verification: CONFIRMED. Two quantitative research internship stints at Citadel Securities are supported by description text on his own Touchmark/LinkedIn post ('2x quant research at Citadel Securities'), the YC company page ('Previously 2x Quantitative Research intern at Citadel Securities'), standout.work ('Previously 2x Quantitative Research intern at Citadel Securities, AI Engineering intern at Lovable'), and a public LinkedIn snippet 'Citadel Securities. Jun 2025 - Sep 2025 4 months'; a techfundingnews article also states 'He spent two stints as a quantitative research intern at Citadel'. Employer classification: Citadel Securities is a market maker / electronic quantitative trading firm (a broker-dealer), squarely within quantitative finance. Identity is supported by the shared IOI-gold + Touchmark (YC S26) anchors across those sources. Role type = internship (Quantitative Research Intern), not a full-time perm role; the 2024 and 2025 dates are the caller-supplied lead and a LinkedIn snippet respectively, and are labeled accordingly.Aug 14, 2026
- Co-founded Touchmark with Ilia Bolgov in April 2026 and entered the Y Combinator Summer 2026 batch; Touchmark is a market for future AI inference capacity (reserving and reselling model-inference compute on an order book), so his current focus is AI-infrastructure market-making rather than quant trading.Jun 2026
- Identity spanning three independent contexts: IOI 2022 stats page shows Roman Yanushevskyi competing for Ukraine (gold), UOI news says he graduated from Kyiv Natural Sciences Lyceum No. 145, and the same name is Co-Founder of Touchmark (YC S26) with an X bio 'prev ioi gold, lovable, citadel' -- three sources that corroborate one identity rather than three namesakes.Aug 2022
- IOI 2022 gold medal finished 7th overall worldwide and was the best Ukrainian result since 2005/2006 and the best European contestant that year, per UOI -- a top-10 world finish, not merely a medal.Aug 2022
- Listed as Founder/CTO on the YC company page while his own LinkedIn headline reads Co-Founder -- the CTO credit implies he built Touchmark's platform, which techfundingnews corroborates ('His co-founder, Roman Yanushevskyi, built the platform').Jun 2026
- Competes under Codeforces handle 'Wailydest' (rating ~2825) and represented NUS at the ICPC 2025 World Finals on the team 'Jägermeister' with Hibiki Nishiwaki and Yuto Watanabe, so his competitive-programming activity continued past IOI into university.Sep 2025
- Education path is a three-country progression: Kyiv Lyceum No. 145 (to 2022), one year of Theoretical Computer Science at Jagiellonian University in Krakow (2022-2023), then Mathematics and Computer Science at the National University of Singapore (2023-2026) -- the move to Singapore coincides with his ICPC/NUS competitive-programming team.2023
- Was one of the first 'Pareto Fellows' (Edward Lando's Pareto fellowship), a credential predating Touchmark -- evidence of an early network into the founder/angel ecosystem that later shows up around Touchmark's launch.Aug 2026
- Touchmark raised a $500k seed round (reported by fundup/aVenture data) and is located in San Francisco, CA, US even though the product page and team are tied to London -- so the SF listing reflects the YC batch base rather than a confirmed personal residence.Jun 2026
- The 2024 and 2025 Citadel Securities dates appear as two separate summer stints (roughly Jun-Sep), consistent with a returning intern pattern across two university summers rather than a single continuous role; the LinkedIn index only shows an aggregate '2024-' span.Sep 2025
- At Lovable he built GPTEngineer.app, an autonomous AI software engineer that creates functional apps from a single prompt -- a project distinct from his quant work and the thread that leads to Touchmark's AI-infrastructure focus.2024
- Extruct's analysis of Touchmark notes a TypeScript SDK (@touchmark/sdk) that records sessions and emits quality-adjusted prices -- the pricing mechanism is quality-based rather than per-token, matching the 'market for inference' framing.2026
