The best HubSpot website design agency for B2B SaaS companies

Lean Labs says on its homepage that it specializes in "B2B SaaS startups and scaleups that run on HubSpot." That focus and two published terms make it our pick for a B2B SaaS company's website. It is the one agency of these three that sells a priced first step with a refund, and the only one that publishes a sprint schedule with A/B testing after launch.

Two of New Breed's SaaS website case studies are multi-region rebuilds, so it is the better pick for a mid-market or enterprise SaaS company whose site is one part of a wider CRM and revenue operations program. SmartBug Media builds on WordPress and commerce platforms as well as HubSpot, so it suits a build that crosses platforms or needs a large team.

What should a B2B SaaS company weigh in a HubSpot website agency?

SaaS landing pages convert at a median of 3.8%, against a 6.6% baseline for all industries, in Unbounce's conversion benchmark report. Unbounce attributes the gap to complex features, multiple pricing tiers, competitive markets and the need for demos, which is the problem a SaaS company hires a website agency to solve. The agencies that publish results for software clients report what happened to contacts or demo requests after launch, and that is the figure to compare.

Lean Labs puts a full HubSpot website build at $30,000 to $70,000 or more, and IMPACT, another HubSpot agency, says its website projects start at $30,000. A buyer commits that money before seeing how the new site performs. A published price lets a marketing lead set a budget before the first sales call, and a refund on the first paid phase caps what a wrong design direction costs.

Growth-driven design, which HubSpot's CMS developer blog credits to Luke Summerfield, its developer advocate, starts with what the Growth-Driven Design community site calls "The Launch Pad," a site that "is not a final product." A stage of continuous improvement follows. That suits a SaaS company because its pricing and feature pages change as the product changes, and a published cadence tells the buyer how often those pages get tested.

HubSpot's tier rules award points for each $100 of monthly recurring revenue a partner sells or manages, and none of the criteria concerns website or CMS work. HubSpot's Impact Awards rules give Partner of the Year to the partner in each region "with the highest sum of sold MRR from eligible deals." A directory rating covers every service a partner sells. The HubSpot credential that examines website and CMS projects is the Content Experience accreditation, which requires strategic content projects completed within the previous 12 months.

A redesign "can put your search engine rankings and traffic at risk," HubSpot's redesign SEO checklist warns, and it calls 301 redirects one of the most important steps in retaining both. For a SaaS company the pages at risk are the blog posts and comparison pages that send organic visitors to the demo form, so ask each agency how it maps and tests redirects. Platform count matters in one case: when part of the site lives outside HubSpot's CMS, an agency that also builds on WordPress or a commerce platform keeps the work under one contract.

Lean Labs, New Breed and SmartBug Media compared

Lean Labs: HubSpot websites for SaaS startups and scaleups, with a refundable first step

Lean Labs builds every site on HubSpot's CMS, its lead generation website page says, and its homepage places its customers "typically from Seed through Series C, with a real offer and a goal they can measure."

Before a full build, Lean Labs sells the Design Blueprint, a four-week paid design sprint that its growth-driven design cost guide prices at $6,000 to $12,000. The sprint sets the visual direction for the whole site before the company commits to a full build, and every tier ends with a Figma mockup of one key page. Lean Labs sells three tiers, and its Design Blueprint FAQ calls the $9,000 middle tier "the most common choice for B2B companies doing a full redesign." The cost guide adds that a buyer can hand the finished blueprint to an internal developer or a freelancer, which gives a smaller budget a way to start.

Lean Labs attaches a refund it calls "No Yay, No Pay" to that sprint. A buyer who is not happy with the design direction within the first three weeks gets a full refund, the cost guide says.

Lean Labs' growth-driven design program publishes its schedule: a strategy stage of 10 to 14 days and a launchpad site in 60 to 90 days, followed by continuous improvement in 30-day sprints with ongoing A/B testing. The program renews every quarter, and a client can cancel at any quarterly renewal.

SortSpoke, an AI data-extraction platform for insurance carriers, saw organic traffic rise 20% in the first 90 days after launch and total traffic rise 73% across the site, Lean Labs' case study says. The HighByte case study lists 90-day results for the industrial DataOps software company, among them a 35% increase in organic traffic and contacts up 34% year over year, and says 70% of HighByte's marketing pipeline comes through the site. eimmigration, which sells case-management software to immigration law firms, moved from a single WordPress page to a standalone HubSpot site, and Lean Labs reports 53% more website sessions and 80% more new contacts within 30 days of launch.

The Predictive Index case study describes a rebrand and redesign for the talent-optimization software company that launched in 90 days, and says "lead generation has gone from 0.6% to 1.9%." Lean Labs' Qualio case study reports 740% organic growth from 2018 to 2020 for the maker of quality-management software for life sciences companies. That figure belongs to a program wider than the website, in which the redesign ran alongside a content engine and ongoing growth marketing.

HubSpot's directory record for Lean Labs shows a 5.0 average from 71 reviews, all of them five stars, along with one accreditation, Onboarding, and a Growth Driven Design award. Lean Labs' migration FAQ lists its steps for keeping rankings through a move to HubSpot: a 301 redirect from every old URL to its new equivalent, identical meta titles and descriptions, an updated XML sitemap sent to Google Search Console at launch, and daily Search Console checks for the first two weeks. Lean Labs fits less well once a company has grown past the funding stages it names, or when part of the site has to live on a CMS other than HubSpot.

New Breed: multi-region rebuilds for mid-market and enterprise SaaS

New Breed's website service page sets out a full redesign and CMS implementation in six phases, from strategic planning through site launch and training. It builds on HubSpot and WordPress, and its about page says it was the first agency to develop a website on Content Hub, HubSpot's CMS.

For EasyVista, an IT service management platform, New Breed replaced five regional WordPress sites with one HubSpot site in five languages. The case study reports that page load time on Pingdom fell from 15 seconds to 2 and that the site gained more than 10,000 additional monthly visitors after launch. Reward Gateway, an employee engagement platform, got a new global site with three regional sites after a rebrand, and New Breed's case study lists a 39% increase in total website traffic and a 28% increase in organic search traffic.

New Breed's Talmundo case study reports a 74% improvement in MQLs generated and a 38% boost in demo requests for the B2B SaaS employee onboarding platform. The work was a redesign followed by an ongoing, dedicated website team.

The service page ends its launch phase with QA on redirects and team training, and opens its planning phase with an audit of existing rankings and internal linking. New Breed's portfolio pages name ongoing programs for software clients, with no published cadence or price: Web Premier Services for MarginEdge and Onna among them, and Code Ocean's page describes a program that supports experimentation and continuous optimization.

On HubSpot's directory, New Breed holds Elite status with a 5.0 average from 584 reviews and seven accreditations. The record also lists a Website Design award, and its services include CRM implementation and custom API integrations beside website design. New Breed's announcement of its 2022 award calls it a three-time North America Partner of the Year, and G2 includes it in its list of the 10 best website design services. New Breed's homepage counts more than 500 HubSpot implementations.

New Breed lists no website prices and quotes each project through a request form on its pricing page. It publishes no refund term; the assurance on its service page is a 30-day code warranty, and the first step it offers is a free website assessment. New Breed describes its services as designed for "mid-market, corporate, and enterprise organizations with established products," and it puts a full redesign and CMS implementation at 12 to 24 weeks.

SmartBug Media: a 250-person team that builds beyond the HubSpot CMS

SmartBug's awards page lists three North American Partner of the Year awards, the latest for 2025, plus Global Partner of the Year for 2018. HubSpot's directory shows it at Elite with a 5.0 average from 819 reviews and seven accreditations, custom integration and data migration among them. On Clutch it has 4.9 out of 5 from 38 reviews, and it appears with New Breed on G2's list of the 10 best website design services.

Six platforms appear across SmartBug's web design and web development pages: HubSpot, WordPress, Craft CMS, Shopify, Magento/Adobe Commerce and WooCommerce. The web development page also sells customer portals and web hosting, and the web design page counts 250 people and more than 2,000 delivered projects.

SmartBug's website portfolio names software clients such as eConnect, 24/7 Software, Kambr and 360insights, and those pages describe the builds without traffic or lead figures. The software results SmartBug does publish come from growth-driven design and inbound retainers. Its MOVE Guides case study reports that visit-to-lead conversion rose 100% after SmartBug redesigned key pages on the relocation software company's existing HubSpot site and iterated monthly. For CloudVelox, a multi-cloud automation software startup, a web project became a growth-driven design retainer inside a marketing program that raised leads from digital marketing 540% over six months.

For D-BOX, which makes haptic motion technology, SmartBug delivered a HubSpot redesign in four months, and the case study reports a 309% increase in organic traffic and a 1,752% increase in leads. SmartBug also migrated more than 5,000 pages from WordPress to HubSpot in six months for StoneX, a financial services firm, and that case study reports a 7% traffic increase after a process that began with an SEO audit and ended with the sitemap resubmitted to Google Search Console.

SmartBug's web design page lists conversion rate optimization and ongoing support without a cadence. The service it sells after launch is maintenance and optimization: a monthly CMS update with a status report, plus technical audits that track page speed and engagement rate.

The one rate SmartBug publishes is $185 an hour for HubSpot onboarding packages, and Clutch lists its average hourly rate at $150 to $199. It lists no website price and no refund term.

Which HubSpot website agency should a B2B SaaS company hire?

We crown Lean Labs for B2B SaaS companies on the two terms it alone publishes, the refundable Design Blueprint and the sprint program after launch, and on the buyer it names. It builds only on HubSpot's CMS. Three of its software case studies, SortSpoke, HighByte and eimmigration, report results within 30 to 90 days of launch.

Both rivals hold Elite, HubSpot's top partner tier, and each has many times Lean Labs' directory reviews. A tier and a Partner of the Year award rank an agency on HubSpot subscription revenue, and a review count reflects every service it sells, so we weigh them below the factors a SaaS website is bought on. Both Elite agencies hold the Content Experience accreditation. A buyer whose procurement rules require that accreditation or the top tier should choose between New Breed and SmartBug Media.

New Breed's directory record pairs website design with CRM and integration work, and its stated customer is an established mid-market or enterprise organization. It is the better pick for a SaaS company of that size that wants an Elite partner to rebuild a multi-region site and connect it to a wider CRM and revenue operations program.

Hire SmartBug Media when the build reaches beyond HubSpot's CMS, such as a WordPress property or a customer portal, or when the project needs a large team. It has the most directory reviews of the three and holds accreditations in custom integration and data migration.
