Why Istanbul companies invest in software
With e-commerce, gaming studios, crypto exchanges and banks, businesses in Istanbul face growing pressure to digitise operations, serve customers online and integrate with partners. The most common requests we receive from Istanbul are crypto payment gateway, e-commerce & multi-vendor marketplace and IoT platform & connected device apps.
Because Istanbul draws talent from Boğaziçi, many companies here run lean in-house teams and use NNT Software to add product engineering, QA, DevOps or AI skills on demand — with delivery scheduled around TRT (UTC+3) working hours.
How we would approach a project in Istanbul
- Start with the workflows that matter most to e-commerce — usually merchant onboarding and checkout & plugins.
- Meet stakeholders in Levent or online for a one-to-two-week discovery workshop.
- Plan hosting and integrations around istanbul Airport and the TRT (UTC+3) working day.
- Combine your local team — often hired from Boğaziçi — with NNT engineers for design, development and QA.

What Istanbul businesses need from software
The core economy of Istanbul
Businesses here typically need secure onboarding, ledgers that reconcile to the cent, real-time payments and audit-ready reporting, and measure progress on onboarding completion rate, time to approve an application and fraud loss rate.
E-commerce in Istanbul
E-commerce companies typically need fast storefronts, omnichannel inventory, loyalty and frictionless checkout, and measure progress on checkout conversion, stock accuracy and repeat-purchase rate.
Crypto in Istanbul
Crypto companies typically need licence-ready custody, transaction monitoring, wallet security and clear user disclosures, and measure progress on deposit-to-trade conversion, withdrawal processing time and share of assets in cold custody.
Gaming in Istanbul
Gaming companies typically need scalable game backends, player wallets, live-ops tooling and anti-fraud controls, and measure progress on daily active players, retention day 7 and payment success rate.
Crypto Payment Gateway for Istanbul
A crypto payment gateway lets merchants accept Bitcoin, Ethereum and stablecoins such as USDT and USDC, with instant conversion to fiat if required. For Istanbul clients we usually begin with payouts (mass crypto and fiat payouts) and compliance, then add merchant onboarding and checkout & plugins. Pricing is set as per your requirements and budget.
E-commerce & Multi-Vendor Marketplace for Istanbul
A multi-vendor marketplace lets many sellers list products while you manage payments, commissions and logistics. For Istanbul clients we usually begin with split payments (commissions, escrow and vendor payouts) and search & discovery, then add logistics and reviews & trust. Typical first release: 12–20 weeks.
IoT Platform & Connected Device Apps for Istanbul
An IoT platform connects devices, collects their data and lets people monitor and control them. For Istanbul clients we usually begin with ota updates (staged firmware rollouts) and rules engine, then add mobile app and device provisioning. Typical first release: 12–20 weeks.
NFT & Web3 Marketplace for Istanbul
An NFT or Web3 marketplace lets users mint, buy, sell and trade digital assets on-chain. For Istanbul clients we usually begin with admin & moderation (curation and reporting) and wallet login, then add minting and trading. Typical first release: 10–16 weeks.
Example project in Istanbul
Picture a textiles business in Istanbul that needs a crypto payment gateway. Discovery and a clickable prototype take about two weeks; the first release — merchant onboarding, checkout & plugins and stablecoin rails — follows in 10–16 weeks.
Customers pay with TROY, personal data is handled under KVKK, the product is hosted on Local Turkish data centres or nearby EU regions, and the team reviews overall equipment effectiveness and scrap rate every month.
