They quoted four months. You needed six weeks. They delivered excuses. You showed up to your meeting with a Figma mockup instead of a live product. Never again.
They said yes to everything in the sales call. Wrong product. Wrong features. Wrong architecture. Months of back and forth and what they handed over wasn't what you asked for. You paid for it anyway.
Your engineers are buried in the core product. This feature can't wait three months for them to surface. Hiring takes six months and burns runway you don't have. You're stuck.
You tried Lovable, Bolt, or Cursor. The demo looked great. Production broke. You lost eight weeks and you're starting over with a deadline that didn't move.
No more guessing. Your deadline — guaranteed.
WingmanAI: 33 hours — replaced their entire frontend & AI. WellChild: 27 hours — HIPAA-compliant platform their last agency took 2.5 months to build. We don't estimate in sprints. We deliver what is needed in full.
From the moment we start, your project lives on a staging URL. See it. Click it. Share it with your investors, your board, your co-founder. Every update visible in real time.
Fixed price. Fixed delivery date. Both in your signed contract. Miss the date — 20% off the project price.
Senior engineers review every line. HIPAA, SOC 2, GDPR, OWASP-ready. Pen-tested. Clean, typed, documented code you own outright. Speed is the system — not a shortcut.
OneSpark
OneSpark runs 95+ specialized AI agents in parallel — scoping, building, and testing your project all at once, not one step at a time. It's built on over 20 years of enterprise delivery experience, the same process behind Fortune 500 and Global 1000 applications, rebuilt from the ground up with AI at its core. Senior engineers review every output before it reaches you. That's how we ship in weeks what everyone else quotes in months.
No bloated timelines. No paying for promises. OneSpark condenses the entire development lifecycle so you see results from day one. Pay for results, not time.
Fill out a short form. We review everything before the call so we come prepared. No fluff, no pitch. We're already thinking about your build before you dial in.
You tell us what needs to be built and when it needs to ship. We work through your project outline together — features, users, platform, integrations, compliance. You leave knowing your timeline, the prototype process, and what the guarantee looks like.
Before you commit a dollar, we take your initial scope and feed it into OneSpark. OneSpark produces an early working version of your product along with a fixed-price proposal. See it. Click it. Share the link. Then decide.
Once you're in, we run a 2–4 hour deep dive to lock in every requirement. Edge cases. Integrations. User flows. The prototype gets refined. The scope gets locked. The clock starts.
We execute the project. See progress every day with a live staging URL from day one. Fixed price. Fixed delivery date. 20% off if we're late.

BOOK A SCOPE CALLThree ways we work with you
For teams who need to build fast
New builds, rescue builds, new features, internal tools, compliance-driven software. You know what needs to be built. We come in, own the sprint, and guarantee delivery.
You have the vision. You need something real.
Not a mockup. Not a prototype. Production-ready, revenue-generating software in front of your investors and users — built fast, owned by you.
For products that shipped and need to keep moving
Your product shipped. Now it needs an engine to keep it moving. Dedicated team, continuous development, powered by OneSpark.

We work with founders and businesses who are ready to move. If any of these sound like you — we're not your team right now:
Come back when you're ready. We'll be here — and we'll be fast.
Enterprise quality.
Startup speed.
Select the date & fill out the form. We review every submission before the call and pre-fill your project outline so you don't repeat yourself. Come ready to move.
OneSpark coordinates 95+ specialized AI agents handling different parts of your project simultaneously — not sequentially. Design, backend, frontend, and testing run in parallel. A senior engineer oversees every project. What takes a traditional agency months, we deliver in weeks. That's not a claim. It's a track record.
Most builds ship in 2–8 weeks. WellChild shipped in 27 working hours. WingmanAI in 33. Your timeline depends on scope. You'll have a clear estimate within 48 hours of your scope call.
20% off the project price if we deliver late. The delivery date is in your signed contract. We built a system that doesn't miss.
We review your form beforehand so we come prepared. We work through your project together — what needs to be built, when it needs to ship, what the guarantee looks like.
After the scope call, we build a working version of your product before you commit to anything. You see it, click it, share it. Only then do you decide. No other dev agency does this.
We run a 2–4 hour requirements workshop to lock in every detail. The prototype gets refined. The full build starts — fixed price, fixed date, live staging from day two.
Every project is scoped and priced based on your requirements and timeline. Tighter deadlines require dedicated resources. You'll have a fixed price within 48 hours of your scope call — before you commit a dollar.
100%. Every line, full documentation, complete access. You're never locked in.
Most clients continue with a Technical Partnership retainer — dedicated team, continuous development, ongoing feature shipping.
