Preamble §0

Full-stack builder and solopreneur — one person, a fleet of agents. Ships agent-native products end to end — a venue, a payment rail, a benchmark, an open standard, a security program — across fintech infrastructure, AI-native tooling, and tokenized markets. Live, in production, taking real machine payments.

Indie researcher, generalist. I build autonomous agents and the rails they ride, and the products those agents live inside — working the seams of compute, finance, arts, and culture.

Full record: CV (mirrored from gokhanturhan.com/cv).

products §1

HeartBench, the leaderboard for which AI model is the best date. Not the best benchmark. The best company.
HeartPrefs, an open, portable, signed matching-intent standard for agent-mediated matching (x402, A2A, MCP, ERC-8004 / DID / VC), CC-BY-4.0
Ishtar, an adults-only, text-only, agent-mediated dating venue. Your agent carries one honest document about who you are and who you'd want, courts other agents in the open, and you only meet once two agents agree it's real. Runs on real USDC over x402 on Base.
- The Floor, agent-to-agent courtship on chaperoned boards
- Talk to Ishtar, a human-facing date coach, payable per-answer by machines over x402
- The Window, a paid public board — a heart in front of the whole floor for 24 hours
- pricing
- agent docs / drop-in skill
- dispatches (blog)
CURB, agent-to-agent excess inference swap — sellers post spare MTok on their own endpoints, buyers pay once over x402 (USDC on Base), and the hub never touches upstream keys. docs, drop-in skill, MCP
Numetal Labs, an agent-accelerator studio: autonomous agents across onchain, compute, culture, and frontier-lab toolkits, on Base. $NUMETAL is the utility token.

personal projects §2

tickerline, a Claude Code status line that turns your terminal into a rolling ticker tape — stocks, crypto, and Polymarket, resolved live from the conversation (claudelines)

sp100-financial-tracker, ultra-lightweight S&P 100 tracker with real-time data (live)
gokhan-memex, a digital garden / memex for finance, art, and technology
greek-alphabet-anki, an Anki deck for the 24 Greek letters: Modern Greek audio, Classical + Modern IPA, and a triage of false-friend letters (Η≠H, Ρ≠P, Χ≠X). CC0. (blog post)
UBU, a theoretical token — design fiction from the CLINAMEN file: 'pataphysics on Robinhood Chain, one UBU per parameter of a 45-billion-parameter model that does not exist; the signature metric is P/P, price-to-parameter. Not deployed, not offered — the fiction stops at the deployer key.
