The software firm whose growth strategy is, mostly, refusing to lose the clients it already has.
The company mark, plain and unfussy. A firm that has moved its Bay Area pin from San Bruno to Marin County while quietly shipping code the whole way.
There is a certain kind of software company that gets written about a lot, and it is not this one. That company raises a Series A, hires aggressively, spends the money on billboards near the airport, and then spends the next eighteen months explaining to its board why the billboards did not work. NEKLO LLC has done approximately none of that. It was founded around 2005, it has never raised a funding round that anyone can find, and its single most-quoted statistic is that 85% of its new projects come from clients who have already worked with it. That is not a growth hack. That is just having customers who like you.
This is a slightly boring thing to be good at, which is exactly why it is interesting. In the professional-services business, the natural entropy is churn: you finish a project, the client moves on, you go find another client, and your sales team lives on a treadmill. NEKLO's numbers describe a company that has largely opted out of the treadmill. It says 63% of its client relationships run past five years. If you are a software agency, that number is either a typo or a moat, and it does not appear to be a typo.
The mechanics of how you get a review like that are unglamorous and worth stating plainly. NEKLO staffs its teams heavy on senior people - by its own account, roughly 70% of the company is senior engineers, analysts, and managers. This matters because the classic outsourcing failure mode is the bait-and-switch: an impressive team shows up for the sales call and a much greener one shows up for the actual work. A firm that is mostly senior does not have a large bench of juniors to switch in. The org chart is the promise.
NEKLO is a US legal entity - headquartered these days in Novato, California, in Marin County, after an earlier stint listed in San Bruno - with engineering roots in Eastern Europe, originally a development center in Minsk, Belarus. This is a common and sensible structure for a firm of this size: client leadership sits in the same time zone and legal system as the customer, while the build happens where senior engineering talent is available and durable. The debate people like to have about this - offshore versus nearshore, cheaper versus closer - mostly misses the point. The question a buyer actually cares about is: who owns the outcome, and can I reach them? NEKLO's pitch is that the answer is yes, directly, with what it calls "radical transparency."
The company was started by three co-founders - Ken Kopilevich, Igor Sundukovskiy, and Maxim Mironenko - and Kopilevich, who holds graduate degrees from UC Berkeley and Riga Polytechnic, still runs it as co-founder and CEO. Two decades under the same founder-operator is itself a signal. Agencies with revolving leadership tend to have revolving strategies. NEKLO's strategy has been remarkably consistent: build software for hard industries, keep the clients, do not chase headlines.
The practical answer is: a lot, but with a spine. NEKLO's deepest specialty is e-commerce, and specifically Adobe Commerce - the platform formerly and forever known as Magento. It holds a Hyva partner badge for modern Magento storefronts and has been doing Magento 2 work long enough that the keyword shows up in every third-party description of the company. Around that spine it wraps the modern menu: web and mobile apps in React, Angular, Flutter and the rest; DevOps on AWS and Kubernetes; Salesforce development; and, increasingly, AI. On its Clutch profile, AI development and AI agents now make up a full quarter of its listed service mix, which tells you where the last two years of client demand have gone.
The industries it serves are the ones where software is hard and mistakes are expensive: FinTech and banking, healthcare, construction, energy, manufacturing, logistics, retail. These are regulated, high-load, legacy-encrusted environments, and NEKLO leans into that by talking about "security by design" - wiring compliance in from the first sprint rather than bolting it on before launch. It is a good line because in fintech and healthcare it is also the cheap option. Retrofitting security is where budgets go to die.
One product worth naming: NEKLO's team contributed to Raken, a construction field-management platform that the Associated General Contractors of America ranked the #1 daily reporting software. Construction is an almost comically underserved software market - much of it still runs on paper and text messages - which makes it fertile ground and also a decent illustration of NEKLO's whole thesis. The least glamorous industries tend to hide the biggest, stickiest software wins. You do not get a five-year client relationship building something disposable.
If there is a critique to make, it is the flip side of the compliment: NEKLO is quiet to the point of being hard to research. Its founding year floats between 2005, 2008, and 2009 across various databases; its revenue is estimated by third parties in the $16M-to-$19M range rather than disclosed; its Bay Area address has wandered. None of this is alarming for a bootstrapped private services firm - it is simply what happens when a company spends its energy on clients instead of press releases. The clients, for their part, appear to have noticed. They keep signing.
