How it works

From idea to shipped in weeks

A streamlined process designed for fast-moving teams who need reliable execution without the overhead.

01

Discovery call

30-minute no-commitment call. We listen, ask the right questions, and align on scope, timeline, and budget.

02

Proposal & NDA

Detailed technical proposal with timeline and fixed or retainer pricing. Mutual NDA signed before any details are shared.

03

Build & iterate

Bi-weekly demos. Daily async updates. You always know what's happening — no surprise delays, no black-box development.

04

Ship & support

Smooth deployment, documentation, and optional ongoing support or maintenance. Your product, your IP — always.

Why Sonira

The simple choice for serious builders

Full confidentiality, always

Mutual NDAs, private repos, no public attribution. We work under your brand, your way. Your clients will never know we exist — unless you tell them.

Fast without cutting corners

Senior engineers only. No junior developers, no outsourced work. We move fast because we're experienced — not because we're skipping steps.

Direct access, founder-level care

You work directly with the people building your product. No account managers, no translation layers. Questions answered same day.

Honest, predictable pricing

Fixed-price milestones or retainer — your choice. No surprise invoices. We tell you what it costs upfront and stick to it.

Our commitment
  • All source code is yours — full IP transfer on completion
  • Zero public attribution unless you request it
  • Mutual NDA signed before discovery call details are shared
  • No lock-in — cancel ongoing engagements with 2 weeks notice
  • Senior devs only — your stack is in expert hands
  • Available globally — async-first, timezone-flexible
  • Documentation and knowledge transfer included
  • 30-day post-launch bug warranty on all projects
How we compare

The smarter choice is clear

Big agencies charge enterprise rates. In-house teams take months to hire. We deliver senior-level output without the overhead.

Client feedback

Trusted by builders worldwide

We can't always share names, but the results speak for themselves. Here's what our partners say.

"We needed a full-stack team that could work under NDA and deliver at a senior level. Sonira did exactly that. The product launched on time, the code is clean, and they've been available for support ever since."

M. K.
CTO, B2B SaaS startup · United States

"I've worked with agencies that charge 3x more and deliver half the quality. Sonira is genuinely different — they care about the product, communicate proactively, and actually meet deadlines."

JS
