Software Development Review from Claus-Peter Mueller
We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.
Web Design Review from Anonymous
Thanks to Infinum's website refresh, the client has seen an almost 100% improvement in their website's conversion rates. The team excels at project management, using the client's own proprietary tool and also Figma very well. Their proficiency in design, delivery, and client relations stands out.

Software Development Review from Michael Levy
Flowty is a blockchain-based platform providing various transaction services around NFTs. K-Optional wears many hats in support of Flowty including Front End, Back End, business strategy, SEO and more.The K-Optional team has been incredible to work with. They are proactive, supportive, smart, thoughtful and, most importantly, fit seamlessly into our team and company culture. To put it succinctly, we tried to hire them full-time...and then tried to buy their company to acqui-hire them.Some of their strengths include: reliability, responsiveness and creativity. There are many groups out there that can perform some version of the work we are looking for. There are not many groups that are responsive at all hours of the day, deliver consistently and able to present data-backed business strategies.
Software Development Review from Jane Smarovozova
We collaborated with K-Optional to develop a custom inventory management dashboard tailored for real estate clients. We provided the creative vision and detailed designs, while their team focused on the software development, ensuring that every element was implemented perfectly. We worked hand-in-hand flawlessly, resulting in a sleek, user-friendly interface that not only looks great but functions seamlessly. The synergy between design and development allowed us to deliver a product that exceeded client expectations, combining aesthetics with powerful functionality.

Confusing technical vocabulary with delivery capability.
An agency can speak the right language in a sales call without having shipped a product at your complexity level.
Buyers get sold on the pitch, skip the portfolio audit, and discover the gap two or three months into a paid engagement when sprint velocity collapses, or early architectural decisions start creating problems that are expensive to reverse.
The way to catch it before signing is to directly ask the agency to walk you through a project that went wrong.
An agency with real delivery experience will talk about the specific decision that caused the problem and what they did differently afterward.
An agency without it will describe the outcome without touching the process.
The proposal is the agency's best effort under zero pressure. If problems appear here, the engagement will have larger ones.
Watch out for some of these warning signs:
An engagement contract should define scope, pricing, revision triggers, milestone timelines, and exit conditions clearly enough that neither party needs to interpret anything.
The clauses most likely to work against you and worth negotiating before signing include:
When two agencies carry comparable credentials, similar pricing, and equivalent portfolios, the deciding factor is almost always how each one behaves during the evaluation process itself.
Test these side by side:
| Differentiator | What a strong answer looks like |
| Account ownership | Named engineer with stated seniority and relevant experience |
| Industry depth | Multiple clients in your sector |
| Risk identification | Specific risks called out about your project |
| Communication cadence | Defined check-in schedule, not "we'll be in touch" |
| Response time | Stated commitment, typically 24 to 48 hours |
| Fee transparency | Written, itemized answer given without hesitation |
| Reference quality | Reference offered without prompting, from a comparable project |
Agencies quote more accurately, onboard faster, and make fewer assumptions when the buyer comes in prepared. Have the following ready before the first conversation:
The last item is underrated, as it allows the agency to understand what you have already attempted and thus spend less of your billable time on approaches you have already rejected.

The decision comes down to what you are building and how long you need to build it.
An in-house hire makes sense when software is a core, ongoing function of the business and will likely require continuous iteration and deeper institutional knowledge. An external hire, on the other hand, makes sense when the timeline is fixed or the technical requirements exceed what a single hire could cover.
If the answer to all these questions is “yes,” then likely a specialized agency is a better fit than an in-house hire:
Software development companies in New York typically charge $100 or more per hour, though rates as low as $40 per hour exist depending on the agency's size and specialization. North American agencies more broadly average $70 to $200+ per hour, with New York firms at the higher end of that range, given local market costs.
Here are some factors that drive price variation:
The quoted number and the final invoice rarely match. Notably, research shows that around 70% of software projects exceed their initial budget, with an average overrun of 27%. The gap usually compounds from several smaller add-ons that were not defined at the start.
The most common “hidden costs” include:
The simplest protection from such overruns is to ask for a written breakdown of every category of work that triggers an additional charge before signing anything.
Not by default, and for most buyers, the assumption works against them.
Larger software development companies in New York bring staffing depth, structured processes, and institutional accountability. For enterprise-level builds with complex compliance requirements, multi-region infrastructure, or large concurrent engineering teams, that scale is genuinely necessary.
For most projects, the dynamic tends to invert: your account gets assigned to mid-level engineers, senior oversight is limited, and the relationship becomes transactional once the contract is signed. The senior developer who impressed you in the sales call may not be the one writing your code.
The more useful question is who will lead your project day-to-day. Ask for the name, seniority level, and relevant experience of the lead engineer and project manager assigned to your account before signing.
Here are some situations that justify switching firms mid-project:
If you decide to switch, you will need: full codebase access and documentation, all environment credentials and infrastructure configurations, a list of open bugs and known issues, and any third-party API keys or service accounts tied to the project. Do not assume these will be handed over without being asked for explicitly; make them a condition of the offboarding.
The best window to switch is between major milestones, after a working build has been delivered and before the next phase begins. Switching mid-sprint, or worse, mid-launch, multiplies handoff risk significantly.
