Founder Bio (short)

Serhat Doğan is a London-based software developer who has been building SMS verification tools full-time since early 2026. He previously worked in consumer apps and digital infrastructure. He runs TwoLine, a one-time phone number service for SMS verification, as a single founder operation.

Founder Bio (long)

Serhat Doğan launched TwoLine in early 2026 to fill the gap left by SMS-Activate's December 2025 shutdown. TwoLine began as a phone number rental service. On 1 November 2026 it stopped selling rentals and moved to one-time numbers for SMS verification. Working solo from London, he ships product, content, and support. Before TwoLine he worked in consumer apps and digital infrastructure.

His public writing on the SMS verification market lives on the TwoLine blog and includes comparisons of published prices, refund terms, country coverage, and number types. TwoLine does not publish its own delivery measurements. The methodology page explains how prices, stock, and supplier-reported rates are shown.

Story Angles for Journalists

Post-SMS-Activate market shift. What happens to a market when its largest player shuts down, and how users scattered across smaller providers.
The "burner phone" privacy myth. Why no commercial burner app actually provides anonymity from the provider, only privacy from the recipient and the platform you're verifying. Founder available for comment.
WhatsApp's anti-VoIP filter. How apps classify numbers by carrier type, and why a number that receives a code can still be refused later.
Solo founder economics in 2026. Building a multi-country service with one person, AI-assisted content, and zero marketing budget. Open to discussing operational details.
Why a rental service stopped renting. TwoLine's move from rentals to one-time numbers, and what honest limits look like on a product page.

Selected Quotes (for attribution)

"SMS-Activate shutting down in December 2025 was the largest single market displacement the SMS verification space has seen. The traffic didn't disappear — it scattered across smaller providers, and most users discovered they cared more about routing class than they did about the brand name." — Serhat Doğan, founder of TwoLine

"The word 'burner' suggests anonymity. Every paid number service, including ours, keeps records of who bought which number and when. The privacy you actually get is from the recipient and the platform, not from the provider or law enforcement. That's a useful product for many real situations, but it's not the same product the marketing implies." — Serhat Doğan

"Most 'free virtual phone number' results in 2026 are public SMS receiver sites where anyone can read your verification code in real time. The cost saving is real — $0 — and the privacy cost is total. I would not use one of these for anything that mattered." — Serhat Doğan
