YarMobile

YarMobile is a Polish software development shop that has spent 15 years building custom applications—but recently pivoted to specializing in AI voice bots. Founded by Jaroslaw Pietras, the company operates from Poland and works with businesses in car repair, dentistry, restaurants, transport, and field service. Their flagship product is a phone-answering AI agent that handles inbound calls, books appointments, reschedules visits, and makes outbound confirmations. A car repair client (Auto Klinika) booked 430 visits in six months using their voice bot; another voice bot picked up 2,300+ calls total. The company still offers custom software development—web apps, mobile apps for iOS and Android, internal tools, and integrations—but voice AI is now their primary focus.

Services and capabilities

YarMobile builds AI voice bots that answer and make phone calls. Inbound bots listen to customer problems, qualify requests, book or reschedule appointments, answer FAQs, and transfer complex issues to humans. Outbound bots call to confirm appointments, reduce no-shows, follow up on leads, collect missing information, and ask for feedback. The voice agent connects to calendars, CRMs, booking systems, helpdesks, POS systems, and email/SMS channels. They build bots in multiple languages and configure privacy rules from the start. The company also handles legacy custom software: web applications (PHP, Vue), iOS apps (Swift), Android apps (Kotlin, Flutter), field service management tools, near-miss reporting software, transport optimization platforms, and IoT device management. Pricing depends on scope and call volume; they typically charge a one-time setup fee (for building and 1–2 months of tuning) plus a monthly subscription based on expected minutes.

Their process for voice bots runs discovery (2–5 days), tailor-made build (2–4 weeks), client testing (1 week), go-live, then ongoing monitoring and refinement for 1–2 months. For custom software, they follow specification → UI/UX design → programming (typically PHP, Vue, Flutter, Kotlin, Swift) → testing on multiple devices → acceptance → installation and publishing → 12-month quality guarantee with free bug fixes and platform updates.

Notable work

Auto Klinika, a car repair shop, deployed YarMobile's voice bot and generated 430 bookings in six months. Ambiente Restaurant uses a voice bot that handles orders, menu queries, scheduling, and delivery zones. HSE Patrol and Aptiv BBS deployed near-miss reporting software. Balticon Transport saw 120% optimization in container management. Transcar optimized its luxury car transport operations. The portfolio includes 50+ projects: Teknika Maps (a sales rep mobile app), ERKUL (HVAC service software), Your Health (a health monitoring app), Pest control scheduling software (70% optimization), Longhair (salon client app), 4ride.pl (online store app), TestDaF (language test app), and WOPR (a rescue worker app). Many are field service, logistics, or healthcare tools. YarMobile also built quiz apps, internal dashboards, and IoT platforms for industrial clients.

How they work

For voice bots, YarMobile starts with a free consultation and quick scope discovery. After agreeing on scope and signing a contract, clients make a 30% advance payment. The team builds a custom voice agent around your workflows: who calls, what they ask, what your systems are. You test with a real phone number, send feedback, and they iterate in tight cycles. Once live, you route all calls, missed calls, or after-hours calls to the bot. A fallback is set up so calls don't drop if something breaks. After launch, they monitor real recordings and refine the agent's understanding and booking rates for 1–2 months. You can modify the bot later (FAQs, scripts, rules) at an additional hourly rate. For custom software, the process is: free consultation → specification and agreement (30% advance) → UI/UX design → programming over several months → testing on multiple browsers/devices → your acceptance and final payment (70%) → installation → 12-month guarantee with free bug fixes and platform updates. Response time: calls or emails within one hour (Monday–Friday, 9am–5pm CEST).

Team and credentials

Jaroslaw Pietras is the founder. The company has been operating since 2009 (15+ years of custom software experience). No team size is explicitly stated on their public site. They work in PHP, Vue, Flutter, Kotlin, and Swift. Voice bot platforms they use include Retell AI and VAPI. Privacy and compliance features are configurable: data collection, storage duration, and consent messaging can be tailored to GDPR or local rules. Recordings and transcripts are logged; they can set fallback routing at the phone level to handle outages.
