Outcome-based software development puts the result at the center of the agreement. Yet “result” can mean different things. A working release may count when it passes agreed tests. System availability, however, must be checked over time. A change in cost or user adoption needs a separate measure after launch. Each promise therefore requires different proof.
This difference matters when comparing outcome-based software development companies. A client’s account shows how a team handled a past project. The proposal, in turn, defines what it must deliver for yours. Below, we compare six firms by service quality, delivery model, and project fit, then explain what proof to request before signing.
Top 6 outcome-based software development companies at a glance
These six companies suit different kinds of projects. Compare their service-quality signals, delivery models, and project fit to narrow your options. Here’s how they compare and what to verify before signing.
| Company | Service-quality signal | Delivery model | Best-fit project | What to verify |
| Eastgate Software | Responsive technical delivery on live systems | Fixed-price project or monthly development team | Enterprise custom software and modernization | Which deliverables and tests define accepted work? |
| Leanware | Structured project management and responsive product delivery | Fixed-fee planning followed by accepted development milestones | Custom software product with defined release milestones | Are fees tied to accepted software or a business metric? |
| Unosquare | Skilled engineers and strong team collaboration | Fixed scope, price, and timeline | Well-defined enterprise software project | Can it provide a client reference for this fixed-scope service? |
| Softo | Involved product team and responsive support | Subscription team for ongoing product development | Evolving digital product and system integrations | What must the team deliver each cycle, and what happens if it falls short? |
| Ailoitte | Proactive updates at development milestones | Fixed-price development with payment on acceptance | Scoped mobile app or software feature | Which defects block acceptance, and who handles rework? |
| CloudGeometry | Responsive migration support in a client project | System assessment, monthly maintenance, and separately priced changes | Software modernization and ongoing maintenance | Can a managed-service client confirm how support and changes work? |
Disclosure: Eastgate Software publishes this article and appears in this comparison. We applied the same selection criteria to all six companies.
How the six companies compare on service quality and delivery
Eastgate Software: fixed-price or monthly custom development
If your scope is defined, our custom software development team can quote a fixed price. When priorities change often, we can provide a monthly team. Our senior-led team handles the work through release and support. In either model, the proposal states what we will deliver, how you will accept it, and whether a business measure affects payment.
Clients have described responsive technical work on live systems. For LeanStation, which builds software for construction teams, we changed the server-side software and release process. That work sped up deployment and reduced production incidents. In another engagement, a client wanted clearer guidance at the outset on how systems would connect. If your project spans several systems, document those connections and the handoff requirements in the plan.
Our Microsoft Azure cloud migration case study reports zero downtime during the move and lower infrastructure costs. The case does not show that savings determined the fee. Ask us to define acceptance tests, delivery responsibilities, and any business measure tied to payment in the proposal. Require the same detail from every finalist.
Leanware: milestone-based software product development
Leanware fits a product build with a defined release plan. It starts with Sprint 0, a fixed-fee planning phase that sets the scope and the tests for accepting each milestone. You pay for milestones only when you accept them. At a milestone boundary, you can exit and keep the work delivered.
Leanware’s product collaboration stands out. For example, a mobile fitness-app client received a working first version with core features, known as a minimum viable product (MVP). The team also responded promptly. Clients also described timely work and orderly project management, though feedback on early design involvement was mixed. If user experience matters, find out who joins Sprint 0 and whether design decisions appear in its acceptance tests.
The product build ties payment to accepted milestones. Adoption or conversion goals may guide the work, but they affect the fee only if the agreement says so. Request a sample milestone schedule and check how the team records acceptance.
Unosquare: fixed-scope software delivery
Unosquare suits projects with clear requirements that can be priced before the build. They also document how the work will be accepted, and price later changes separately. After launch, a support window begins. To avoid disputes over changes, define which requests belong in the original scope.
Unosquare’s engineers joined the client’s daily design, development, and testing work on a customer identity system, which handles user access and sign-in. Delivery stayed on schedule. Even so, the client wanted a smoother way for new engineers to learn the system. For a long engagement, ask how the team documents decisions and brings new members up to speed.
The identity project shows Unosquare engineers working inside a client’s team. Unosquare also offers Outcomes, a separate service where both sides agree on the work, price, and timeline before development. To assess that service, review a sample change order showing how added work affects price and schedule, and check which code and documents the team hands over. The offer covers completion of the agreed work. If you want fees tied to revenue or user adoption, ask Unosquare to state that condition explicitly in the proposal.
Softo: subscription teams for continuous product development
Softo calls its subscription-based development teams Outcome Pods. A pod is a team that works on a product over time, with priorities changing after each release. Its senior engineers and artificial intelligence (AI) specialists build features and connect systems as that work continues.
In a project to build an invoice module, Softo’s team took ownership and kept the client informed. Obstacles and scope changes extended the timeline, though the client wanted a clearer forecast at the start. If you hire an ongoing pod, ask what it will deliver in the next work cycle and when that work will reach the live product.
Softo links pod planning and pricing to results, but it does not specify what happens if an agreed result is missed. Ask what counts as completed work, who accepts it, and how unfinished work affects the next cycle and payment. The invoice project shows how the team handled delivery. A sample pod agreement should show what the fee buys.
Ailoitte: fixed-price engineering with milestone acceptance
Ailoitte’s fixed-price model starts with a written description of the app or feature and the tests it must pass. Payment follows acceptance of the working software. If a planned development cycle overruns, Ailoitte says it absorbs the extra work. At completion, it transfers the code and documentation. This model fits a defined build whose tests can be agreed before development.
Ailoitte is famous for resolving blockers early and keeping the client informed at milestone reviews. In a feedback published in 2023, Koovs.com, an online apparel and footwear seller, said Ailoitte’s mobile app team resolved blockers early and kept it informed at milestone reviews. Another client, however, wanted stronger testing to catch small issues sooner. Before sign-off, agree which defects prevent acceptance and how long Ailoitte has to fix them.
Ailoitte’s process includes demos and acceptance checks every two weeks. Ask for a comparable project example that shows what happens if a demo succeeds but a production test fails. Here, the contracted result is software that passes agreed tests. If you want payment tied to adoption or another business result, specify how to measure it and when payment is due.
CloudGeometry: managed maintenance for existing software
CloudGeometry fits an existing system that needs regular maintenance or updates in stages. It calls its managed service AI-Managed Software Lifecycle (AI-MSL). The service begins with an assessment that produces AppGraph, a map of the code and its dependencies. A monthly plan covers agreed maintenance. For larger changes, CloudGeometry documents the requirements, reviews their impact, and estimates the work in DevCredits, its units for pricing software changes, before work begins.
CloudGeometry helped DiffusionData, a provider of real-time data software, move workloads to Kubernetes, a platform that runs container-based applications. Its automation reduced configuration errors and made releases more predictable. DiffusionData also described responsive support. That project shows how the team handled a migration. To assess AI-MSL, ask for a reference from a client who has used its assessment and DevCredit process.
Ask CloudGeometry to walk through one change, from assessment to acceptance in the live system. Check what the monthly fee covers and when DevCredits apply. Then find out who approves a revised estimate. This will show where routine maintenance ends.
Outcome-based software development contracts: deliverables vs. business results
Before signing, define what the contract counts as a successful outcome. The table below shows what each promise depends on and what to verify in the agreement.
| Contract outputs | What counts as success | What affects the result | Define before signing |
| Software deliverable | The agreed software passes acceptance tests | Clear scope and software quality | Who runs the tests, which defects block acceptance, and who fixes them |
| Service level | The live system meets an availability or response-time target | How both parties operate and support the system | Measurement period, excluded events, and what happens if the target is missed |
| Business result (KPI) | An agreed change in cost, time, or adoption | Data quality and actions the client controls | Starting measure, measurement period, the vendor’s contribution, and when payment is due |
Suppose a vendor launches a customer self-service portal that passes its acceptance tests. The buyer later receives fewer support tickets. Passing the tests confirms that the software was delivered, while ticket reduction is a separate business result. If payment depends on fewer tickets, the contract needs a starting ticket count and a measurement period. It should also say how staffing or policy changes that affect ticket volume will be handled.
For an ongoing product subscription, first define what the fee buys. Are you paying for the team’s time, software changes you accept, or a measured business result? Put that promise in the contract, along with what happens if the provider misses it. Our outcome-based versus time-and-materials guide explains how these payment models divide delivery risk.
What to verify before hiring an outcome-based development company
Define software acceptance and rework in the contract
Ask for a sample project schedule that names each deliverable and the test for accepting it. Decide who runs those tests and which defects prevent sign-off. Set a period for fixing defects, and require approval before a scope change alters the price or deadline.
For an ongoing team or managed service, define what counts as completed work in each cycle. A subscription fee alone does not promise a set number of releases. Our guide to evaluating a custom software development company also covers governance and technical fit for mission-critical projects.
Measure business results and define payment terms
If payment depends on a business result, agree on the starting value (baseline), the target, and the period for measuring change. Also state what your team will do to support adoption and keep the data accurate.
Then decide how other changes will affect the result and the fee. Make sure to set a process for resolving disagreements about the measurement before work begins.
Which outcome-based software company fits your project?
Start with how much of the work you can define now. If the release scope and tests are clear, a fixed-price project with approval at each milestone may fit. If user feedback is likely to change priorities, an ongoing team can plan the next release as the product evolves.
For an older system with many connected parts, begin by assessing how those parts depend on one another. Then make changes in stages and check each stage before moving on. The guide to modernizing legacy systems explains how this approach can limit disruption.
Give each finalist the same sample project scope and ask who would work on it. Compare how they would test and approve completed work, handle changes, document the system, and provide support after release.
Final words
Outcome-based software development starts with a clear promise: what will be delivered, and how will you know it is complete?
Ask each finalist what the fee covers and how you will check the result. If payment depends on a business measure, agree on its starting value and how long you will track it before work begins. If Eastgate is on your shortlist, share your project scope. We will set out our delivery approach and responsibilities in a proposal you can compare with the others.
