From our office in Kraków, Poland, we design, build and scale SaaS products on React, Next.js and Node.js, from the first MVP to multi-tenant platforms used by enterprises. Speeki started with us as a single tool in 2020 and is now a compliance platform used by 100+ enterprise clients worldwide.
A SaaS product needs things a website or a one-off app doesn't: multi-tenancy, subscriptions and billing, roles and permissions, integrations, and an architecture that copes as customers and features grow. We have built and scaled SaaS platforms for compliance, education and public institutions, so we know where the hard problems usually are.
We work with founders launching a new product and with SaaS companies that need to scale, modernise or ship faster. Our stack is React, Next.js, Node.js and NestJS, typed end to end, which suits products that will run for many years.
Test your idea with a focused first version built on architecture you can keep. See our MVP development services.
We design tenant isolation, organisation management, roles and permissions from the start. For Spark, an innovation portal used by schools and institutions, we built multi-organisation management with five user roles.
Subscriptions, payments, single sign-on and integrations with the tools your customers already use, built as documented APIs.
When a SaaS product outgrows its architecture, we help it change shape. We moved Speeki from Java, Kotlin and PHP to Node.js microservices and React while it kept serving enterprise clients, and the platform is ISO-audited. See our modernisation services.
Dashboards, onboarding flows and admin panels that customers can use without training. Our product designers sit in the same team as the developers.

We start with the business: who your customers are, how you will charge them and what the first release must do. We also look at the features and integrations further down the roadmap, so early technical decisions don't block later growth.

From MVP to enterprise scale
A long-term product team
Speeki grew with us from a single whistleblower tool into a compliance platform serving 100+ enterprise clients, with a full migration to Node.js microservices along the way. What we learnt on that platform shapes how we start every new SaaS product.
SaaS products keep changing after launch. Most of our SaaS clients work with us for years, through a dedicated development team or team augmentation. Our team is in Kraków, in your time zone or within one hour of it.
They’ve already trusted us.
The services DnD team has provided POSSIBLE have been of excellent quality of delivery - on time and budget. During the development process they are punctual and reliable, always focusing on meeting deadlines but with a particular eye on quality of service. DnD team has been always available and their communication was flawless. All in all, it's been a pleasure working with them, so I'm more than happy to recommend the services of DevandDeliver.
