Startup Review from Alexa Ginsberg
What stood out most about working with AppMakers USA was how attentive and helpful the team was throughout the project. They listened to our feedback, kept us updated and were always available when we had questions. Everything was handled professionally and we felt confident that our project was in good hands. Were very pleased with the final outcome!
Startup Review from Roei Schneider
I work in IT support, so I was probably more interested in whether this would save us headaches than whether it looked impressive. AppMakers spent time understanding why tickets were getting stuck and found that a lot of our delays were actually caused by people not knowing who was supposed to do the next step. That was a very simple observation, but we had never really stepped back and looked at it that way. The system they planned would make ownership much clearer and let employees see what is happening without constantly asking us for updates. I liked working with them and would do it again.
AI Automation Review from Alessia Anticoli
We partnered with AppMakers to explore an AI-powered solution that could simplify the way our marketing team manages content across multiple hospitality properties. From the beginning, their team focused on understanding our actual workflow rather than proposing a generic solution. They carefully analyzed how we organize photos, approve captions, coordinate promotions, and manage content between different properties. Through the research phase, they identified several inefficiencies we hadn't fully recognized, including duplicated work and unclear approval processes. They then presented a well-structured concept for a shared platform with dedicated content libraries, approval workflows, and AI-powered writing assistance tailored to the unique voice of each property. Communication was always smooth, timelines were respected, and the entire process felt collaborative and well organized. What impressed us most was their understanding that every hospitality brand needs its own identity, and that technology should support that rather than standardize it. The project gave us a much clearer roadmap for improving our internal marketing operations, and we would gladly recommend AppMakers to any company looking to combine AI with practical, business-focused solutions.

AI Development Review from Jordan Sands
Krazimo built us a fully bespoke, AI-powered CRM ecosystem that completely replaced our patchwork of Salesforce and legacy EHR tooling, unifying our website, Instagram, TikTok, and email channels into one centralized lead funnel. The platform's standout layer is a set of intelligent AI agents that hold live conversations with prospects and existing patients, field initial questions, and trigger downstream automations — essentially putting top-of-funnel outreach and nurturing on autopilot while still guaranteeing an instant, high-touch response. On top of that, the system serves as our day-to-day operational backbone, with a quoting engine, inventory tracking, an integrated accounting module, and a built-in call center surfacing real-time sales activity, plus a compliant medical note-taking feature that converts clinical documentation directly into targeted marketing workflows. The measurable impact has been significant: a 15–20% lift in new leads, a 15% bump in lead conversion, and roughly 30% less manual labor across the business thanks to the automations they introduced. Their project management was genuinely outstanding — whether we reached out by phone, email, or text at odd hours, replies came back almost immediately, and they accepted every round of feedback without pushback and turned around revisions on the spot, which kept a very ambitious build on track. What impressed me most was the blend of velocity, efficiency, and unusual transparency: they custom-engineered the AI agents and automations around our specific bottlenecks rather than dropping a generic product on us, and they were refreshingly candid when something wasn't technically feasible or wouldn't deliver the result we wanted, which is rare in this space and made them feel like a real strategic partner rather than a typical vendor. Honestly, I can't point to anything I'd want them to do differently.
Software Development Review from Max Pena
Krazimo turned our software concept into a reality. They have a great team of developers and they made the process smooth. We have been working closely with them since the inception of our software, and our beta users have been impressed with the experience. Now we are preparing to launch our product. Overall, they are a fantastic partner when it comes to creating a high quality solution that can scale!
Software Development Review from Filippo Bellia
I'm the CEO of BlinkVoice, a VoIP provider. We needed help developing sales software, so we brought in Krazimo to build it. They developed a mobile and web app with conversational AI, handling both frontend and backend a voice-first sales training platform built on the OpenAI Realtime API that combines AI-simulated buyer calls, peer-to-peer role plays, and a note-taker that joins real sales meetings to produce transcripts, talk-to-listen ratios, and objection tracking. Managers can upload product docs and competitor materials to generate custom AI buyer personas, and the dashboard pulls everything together with skill scoring, benchmarking, and leaderboards. We worked with a team of 3 from Krazimo, led by a founding engineer with a Google background. We found them through an online search and chose them over other options because of their high ratings and aligned values. We started in April 2025, the engagement is ongoing, and theyve delivered faster ramp time for new reps, stronger discovery and objection handling, and scalable coaching without manager burnout. What impressed me most is how fluid they are with everything. Honestly, I don't think there's anything they need to improve on.

App development companies for startups in the US create digital products that attract users and investors. They handle everything from market research and UI/UX design to coding and launch support, helping startups bring their ideas to life, validate concepts quickly, and reach the market faster.
The best US startup app development companies focus on strategy as much as coding. They shape the product roadmap, test ideas with real users, and build MVPs that prove market fit. Their teams combine tech expertise and startup experience to guide founders through funding, scaling, and product optimization.
Startup app development services in the US start at $5,000 and can exceed $300,000.
US developers usually charge around $100 per hour, and maintaining the app afterward adds another 15–25% of the initial cost per year.
A basic MVP usually takes 3–4 months from planning to launch. More complex apps, especially those that require advanced features, API integrations, or cross-platform development, can extend to 6–12 months, depending on team size and testing cycles.
Top US startup app development companies often use frameworks like React Native, Flutter, Swift, Kotlin, and Node.js, along with cloud platforms such as AWS, Google Cloud, or Azure. For design and testing, they use tools like Figma, Jira, and GitHub to streamline collaboration and speed up releases.
Startup app development companies in the US build flexible architectures that handle growth in users, data, and features. Many offer post-launch support, analytics tracking, and iterative development plans. Their goal is to keep the app stable, secure, and adaptable as the startup scales or enters new markets.
