About NerdCow
NerdCow is a London-based web design agency for SaaS and B2B tech businesses, set up in 2015 and run by its founder, Tomasz Lisiecki, who is involved in every project day to day. Projects start with an alignment workshop and a user-tested website prototype, then move to a build optimized for conversions and search, followed by 6-week cycles of data-backed updates and ongoing support.
Our overview
NerdCow is a small London-based web design agency for B2B SaaS and tech, founded in 2015 and run by Tomasz (founder) and Dawid. They build on WordPress only, with a deliberate "no page builders, no plugin bloat" philosophy and bespoke backends rather than off-the-shelf themes.
The model is a monthly membership with unlimited access to the team, framed as ongoing iteration rather than one-off project work. After scaling up and then deliberately scaling back down, the agency now keeps a small client roster and the founders handle delivery directly. Notable clients include Doddle Logistics and Transport Exchange Group (where they doubled lead generation rates). 4.9 Clutch rating across 100+ reviews.
Best fit for: B2B SaaS marketing teams that want a hands-on WordPress partner for a high-converting site plus ongoing iteration, and who value direct founder access over agency layers.
What does NerdCow do?
NerdCow is a London web design agency for SaaS and B2B tech businesses. Its website says a site should work around the clock to turn traffic into quality leads, and its services follow that idea from planning through to the changes made after launch.
- Planning: alignment workshops (including remote workshops) and sprint planning
- Prototypes: website prototypes, with user testing before the build
- Build: web design and web development
- After launch: data-backed updates, website optimization, SEO and lead generation
The order matters here. The workshop and prototype come before any design is signed off, so expect to give your sales and marketing teams’ time early on.
Who does NerdCow work with?
NerdCow’s website names SaaS and B2B tech as its main market. It also lists logistics, biotechnology, construction and construction forecasting, and B2B marketing among the industries it has worked in.
Clients named on its site include Transport Exchange Group (also shown as TEG), Courier Exchange, Doddle Logistics, nPlan, Repositive, NFDC, Leftover Currency and Views. Several of these are logistics businesses, so buyers in that space will find the closest examples.
How does NerdCow work?
The agency says it was founded in 2015 and lists one office, in London. Its process, as its website describes it, runs from an alignment workshop to a tested prototype, then the build, then regular updates based on data.
That last step is the one to understand before you sign. NerdCow presents the website as something to keep improving after launch, so ask what the ongoing work includes and how it is charged.
The site describes NerdCow as voted top web design agency in London. It does not say who ran the vote.

NerdCow is a London web design agency for SaaS and B2B tech businesses, run by its founder Tomasz Lisiecki since 2015. Every project starts with a workshop that gets marketing, sales and other teams to agree how buyers should move through the site, and ends with a user-tested prototype, in as little as five business days. The site is then built from that prototype for conversions and search, using a design system and custom templates that make new content quicker to create, and kept improving through 6-week cycles of data-backed updates.
Clients include Transport Exchange Group, where the lead generation rate doubled, Doddle and Repositive, and the agency is rated 4.9 out of 5 on Clutch. It suits B2B SaaS marketing teams that want their website treated as an ongoing lead source rather than a one-off project.
