From a customer — real MVP delivered in under 24 hours

“I'm a welder and shop owner, not a developer. Years ago I took this same idea to a professional app company, one that builds apps for a living, and they quoted me over $50,000 and several months just for a minimal version. I brought Sindri my spec, and from the time I submitted it to a working MVP was less than 24 hours, with bells and whistles I hadn't even asked for. My whole family has used it every day since.”

Frequently asked questions

How much does custom software development cost?+

Sindri uses fixed-price tiers, not hourly billing. Builds start at $3,000 for a Micro project (a landing page, lead capture, or simple tool), $9,500 for a single-feature SaaS Tool, $16,500 for a multi-feature Platform with payments and integrations, and $38,000 for a Complex platform with AI features and custom integrations. You see the exact price before you pay — no scope creep, no surprise invoices.

How long does it take to build an MVP or app?+

Days, not months. Micro builds ship in 5–7 days, Tool-grade builds in 10–14 days, Platforms in 3–4 weeks, and Complex builds in 4–6 weeks. Your timeline is guaranteed in your quote.

Do I own the code?+

Yes. You receive full source code ownership for everything we build — no licensing fees, no vendor lock-in. It is your software to host, modify, and extend however you choose, deployed on your domain.

What if the build is not done?+

If we cannot deliver everything that was scoped, you receive a refund proportional to the features that were not completed — no arguments, no negotiations. You also keep full ownership of everything that was completed, deployed and ready to use.

What kind of software can you develop?+

We build MVPs, full SaaS products, internal tools, dashboards, customer portals, and AI-powered applications. Whether you need to validate an idea fast or ship a production-grade platform with auth, billing, and integrations, we scope it from your spec and deliver working software.

How is Sindri different from a traditional software development agency?+

No sales calls, no hourly billing, and no open-ended timelines. You describe what you need through an AI-guided intake, get a fixed price and guaranteed delivery date up front, and receive working software in days. AI-accelerated scoping and development lets us move far faster than a traditional agency at a fraction of the cost.
