Custom software you can operate and grow
Most agencies deliver software the way a courier delivers a box: they drop it and drive off. Doomity builds custom software your own team can operate, maintain and extend after we leave: documented architecture, automated tests, and every account in your name from day one. Before you commit a build budget, we run a Technical Clarity Sprint, fixed scope, so the first thing you buy is certainty, not code.

Do you actually need custom software, or will off-the-shelf do?
Buy off-the-shelf when a standard tool covers most of your workflow and your process can bend to fit it. Build bespoke only when the workflow itself is how you win, and forcing it into someone else's product would cost you the advantage. Doomity applies this test before quoting anything, because the cheapest software is the software you do not build.
| Buy off-the-shelf when… | Build custom when… |
|---|---|
| A standard tool covers 80% of the workflow | The workflow is the thing that makes you money |
| Your process can adapt to the software | The software must follow your process exactly |
| The need is common to thousands of companies | The need is specific to how your business operates |
| A subscription fits the budget better than an asset | Per-seat pricing has outgrown the cost of owning it |
If a $99-a-month SaaS solves your problem, we will say so in the first call and the conversation ends there, free. Custom software is an asset with a maintenance bill attached. It only makes sense when it earns more than it costs to keep alive, and an honest vendor tells you which side of that line you are on.
How does Doomity build custom software, from first call to handover?
Every Doomity build follows the same five steps, and the first one is deliberately small: you should not have to bet a full budget to find out how a vendor works.
- Technical Clarity Sprint. A fixed-scope engagement that turns your idea into a risk map, an architecture outline and a 30/60/90-day roadmap. Priced upfront, useful even if you build with someone else.
- Kickoff in your name. Repo, cloud and CI accounts are created under your ownership before the first line of code. No vendor lock-in by design.
- Architecture, written down. Every significant decision is recorded with its trade-offs, so the next engineer understands why, not just what.
- Iterative delivery. Working software lands in your environment every one to two weeks. You steer with real screens, not status reports.
- Support and handover. Documentation, tests and training for your team, or an ongoing maintenance agreement if you prefer.
The full process, including what each step delivers, is documented at how we work.
What proof is there that Doomity can build your system?
Doomity LLC is a software development firm specializing in custom software, legacy modernization, AI prototype-to-production, software project rescue and technical due diligence, serving clients in the US, UK, Spain and Portugal. Its engineers come from teams that have built for Holcim, Canon España and Indra, including a global data platform integrating sources across plants and countries.
We build on mainstream, hiring-friendly stacks: TypeScript and Python on managed cloud infrastructure, PostgreSQL by default, and nothing your next hire has never heard of. Boring technology is a feature. The failure mode we engineer against is well documented: a McKinsey–Oxford study of 5,400 IT projects (October 2012) found large projects run 45% over budget and deliver 56% less value than promised. Process is the defense, which is why ours is published, not pitched.
Who owns the code, and what happens after launch?
The code is yours from the first commit. Repo, cloud and CI live in accounts you own, the IP assignment is written into the contract, and the handover assumes any competent team could take over tomorrow. That is the test of a real bespoke build: it survives the vendor leaving.
On guarantees, our position is strict: Doomity guarantees process and deliverables, never outcomes. A vendor promising revenue figures for software that does not exist yet is selling you their forecast, not their engineering. What we commit to is verifiable: dated deliverables, tested code, documented decisions. And when your custom system eventually grows old, as all software does, the same firm handles legacy modernization, so the exit path exists before you need it.
How much does custom software development cost in 2026?
There is no honest single number, but there are published market ranges. Development firms listed on Clutch mostly bill between $50 and $99 per hour (Clutch.co pricing data, 2026). FullStack Labs' pricing guide puts small systems at roughly $50,000–$150,000 and enterprise programs at $500,000 or more. And Saritasa reports its takeover clients spend a minimum of $80,000 a year, a useful floor for what serious ongoing development costs.
Doomity quotes after the Technical Clarity Sprint, not before, because a fixed price on an unscoped problem is either padded or the seed of a dispute, and you pay for the padding either way. Not sure whether your project is ready to scope? The Build Scorecard takes three minutes and tells you. And if what you want first is a number, the cost estimator gives you an honest market range in under a minute, no email required.
FAQ
Buy off-the-shelf when a standard tool covers most of the workflow and your process can adapt to it; build custom when the workflow is your competitive advantage and bending it to a generic product would cost you money. Doomity applies this test in the first call and will tell you, in writing, if a SaaS subscription solves your problem. Filtering out projects that should not exist is cheaper for everyone than building them.
You do, from the first commit. The repository, cloud accounts and CI pipelines are created in your name at kickoff, and the contract assigns all IP in the delivered work to you. There is no license-back clause and no proprietary framework you can only run with us. The handover package (documentation, tests, architecture decisions) is built so any competent team could take over, which is exactly what makes it safe to stay.
Published market context: firms on Clutch mostly bill $50–99 per hour, FullStack Labs' pricing guide puts small systems at roughly $50,000–$150,000 and enterprise programs at $500,000 or more, and Saritasa reports clients spending a minimum of $80,000 a year on ongoing development. Doomity gives you a scoped number after the Technical Clarity Sprint, because pricing unread requirements means padding the quote, and the padding lands on your invoice.
It depends on scope, and honest vendors say so before showing a calendar. What we commit to instead: the Technical Clarity Sprint produces a 30/60/90-day roadmap with dated milestones for your specific project, and iterative delivery puts working software in your environment every one to two weeks from kickoff. You see progress in running screens within the first month, so "how long" stops being an act of faith and becomes something you verify continuously.
Mainstream and hiring-friendly by policy: TypeScript and Python, PostgreSQL by default, managed cloud infrastructure, and automated tests from the first sprint. We pick technology your next hire already knows, because an exotic stack is a hidden vendor lock-in even when you own the code. If your project genuinely needs something outside that core, the Technical Clarity Sprint says so explicitly, with the trade-offs written down for you to challenge.
With the Technical Clarity Sprint: a fixed-scope, fixed-price engagement that turns your idea into a risk map, an architecture outline and a 30/60/90-day roadmap. Book a 25–30 minute call, walk us through what you want to build and why, and we scope the Sprint on that call. The deliverables are yours to keep and vendor-neutral: build with Doomity, another firm, or your own team, with evidence on the table either way.
Yes, fully remote, with clients across the US, UK, Spain and Portugal. Our working day overlaps Western European hours and US Eastern mornings, and every project has scheduled checkpoints inside your business hours. Iterative delivery makes remote work verifiable: you review running software in your own environment every one to two weeks, so oversight does not depend on sitting in the same room, or the same country, as the engineers.
Yes, as an option, never as a hostage situation. You can take an ongoing maintenance agreement with defined response times, or take the handover package (documentation, tests, training) and run the system with your own team. Because the code, accounts and infrastructure are yours from day one, switching between those modes later costs a conversation, not a migration. Bespoke software you cannot leave the builder of was built wrong.
