10 Best SaaS Design Agenciesfor Series B Startups (2026)

Best SaaS design agencies for series B startups

By Series B the product is load-bearing. Customers have built process around it, trained staff on it and integrated it, so the constraint on any redesign is that nobody can be asked to relearn their job. Three years of features shipped by four different product managers have to be reconciled into one system, while enterprise deals arrive demanding roles, audit trails and single sign-on that the original data model never anticipated. The number under all of it is net revenue retention, which a redesign can move in either direction.

Ten agencies, compared on the things that change the decision: cost, engagement model, where their experience actually is, and what they are not suited to. Every agency here carries a verified Clutch profile, and the ratings below are taken from it. Each entry says what an agency is worth hiring for and where it is the wrong choice for SaaS design at Series B.

Best SaaS design agency for Series B startups: Bricx

Bricx is the best Series B companies redesigning a product customers already depend on, where the risk is not a bad screen but a support queue full of people who cannot find their work. Bricx has completed 50+ SaaS design projects across 30+ industries, with clients including Writesonic (YC S21), Collectwise (YC F24), Gigacatalyst (YC X26), Sybill, Camb.ai, LTV.ai, Instadapp, Hobbes and AT Kearney. The agency holds 27 verified reviews on Clutch at an average of 5.0/5.

Bricx works exclusively with B2B and AI SaaS companies, from seed stage through Series C, covering branding, website design, product UX/UI and end-to-end development. Engagements start at $25,000. Bricx runs seed through Series C, which means it has seen the same products redesigned twice, and it treats a Series B rebuild as a migration with a rollout plan rather than a new Figma file. Its client list, Writesonic, Sybill, Camb.ai and Instadapp, is products already in market.

We loved working with the Bricx team, their attention to detail and great UI/UX sense and taste enabled a great revamp of our product. Highly recommend!

Itransition

Itransition is the rare firm here that spends more time on ERP and CRM systems integration, 20% and 15% of its work, than on anything else. At Series B that stops being a back-office concern: the enterprise deals arriving now expect the product to sit beside a CRM and a finance system, and those integrations become interface surfaces. It has run since 1998 at $25 to $49 an hour.

No design service appears in its published mix, and its reviews describe feature development, testing and backend infrastructure rather than product decisions. With 1,000 to 9,999 people and 30% of clients at enterprise scale, this is delivery capacity for a specified roadmap, not a team to hand a redesign to.

Lemberg Solutions

Lemberg Solutions is half IoT development, with cloud consulting at 25%, and its published work is firmware for battery management, embedded software on a modem and connectivity through Starlink. For a Series B SaaS product fed by devices in the field, the hard interface question is representing a reading that is stale or a device that is offline, and this team knows why that happens.

There is no design line in its service mix and nothing in its record is application UX, so a purely software product gains little here. Its industries are supply chain at 30% and energy at 25%, which is where the device-shaped work lives, and 60% of its clients are midmarket.

Metacarbon

Metacarbon does nothing but UX/UI, at 100% of its work, and one review describes precisely the Series B job: redesigning an asset management company's existing customer portal, delivering finalised layouts plus a design system. Named clients include You.com, Slash and Koala. Financial services is 30% of its client base, where a portal redesign has to survive users who open it daily.

Ten to 49 people founded in 2019, with no development line at all, so the rollout, the migration and the two versions running side by side stay somebody else's problem. A Series B with thin engineering capacity will find the design arrives faster than it can be shipped.

Net Solutions

Net Solutions names enterprise application modernisation as 20% of its work, which is the honest description of what a Series B product needs after three years of accumulation. Seventy percent of its clients are midmarket, the highest concentration on this page and the band a Series B company is moving into. It has run from Toronto since 2000 at $25 to $49 an hour.

Its 4.7 rating is the lowest here and eCommerce is its largest industry at 30%, not software. One review describes building an app from the client's own design specifications, which is the relationship on offer: modernisation engineering rather than design direction, at a $50,000 floor.

Octet Design Studio

Octet Design Studio is pure UX/UI at 100%, the cheapest such practice here at $25 to $49 an hour, and information technology is 40% of its clients. Its reviews are all reworking what already exists: simplifying a software product's usability after user research, and revamping a document management system by refining its information architecture first. That sequence is what a Series B redesign needs.

At that rate a large team is doing the hours, and there is no development line, so migration and rollout stay in-house. Retail at 15% and manufacturing at 10% follow its IT share, so multi-tenant conventions like seat management and audit trails are not visible in its published record.

Boldare

Boldare's reviews describe deploying developers and UI/UX designers directly into a client's own product team, which is the arrangement most Series B companies actually need: extra hands inside the existing team rather than a redesign handed over the wall. Its mix is balanced across custom software development at 30%, with AI development, UX/UI and web development at 20% each.

Augmentation cuts both ways: a team embedded in your process will not push back on decisions the way an outside partner does, and design leadership stays your problem. Its industries are business services, energy and information technology at 20% each, with government at 10%, so multi-tenant SaaS is one thread among several.

Column Five

Column Five is the only firm here that declares itself a B2B SaaS marketing agency, with information technology at 50% of its clients and 70% midmarket. Its published work is an interactive industry report, a brand video and content programmes. At Series B the story usually has to be retold for a market larger than the one that got the company here.

No UX/UI or product design appears anywhere in its service mix, which runs content marketing at 15%, video at 15%, branding and graphic design at 10% each. It cannot touch the product, so a Series B whose retention problem lives inside the application is buying the wrong half at $150 to $199 an hour.

Glow Design Agency

Glow Design Agency has the most concentrated B2B software client base on this page: information technology at 55%, financial services at 25% and business services at 20%, with nothing consumer at all. Ninety percent of its work is UX/UI, and its own description names SaaS dashboards and AI products, which is the surface a Series B has most of and understands least.

The published record leans to the marketing side, personas and video for a messaging platform, a website and landing pages for a lender, an animation for a software company. Founded in 2019 with 10 to 49 people, it shows less evidence of migrating a mature product than of designing new surfaces.

Lazarev.

Lazarev. publishes more redesigns of live applications than anyone else here: a SaaS app whose look and functionality were both reworked, and a web application given more modernised navigation. It also keeps business analysts alongside designers, which matters when the first task is working out what three years of features were supposed to do. UX/UI is 30% of its mix.

Its $100,000 minimum is the highest on this page, which rules it out for a staged redesign of one surface at a time. Nineteen Clutch reviews across a 50 to 249 person studio is a moderate record, and its industries spread into manufacturing and medical at 15% each rather than concentrating in software.

How much does a Series B SaaS design engagement cost?

The quoted range. From $2,500 at the floor to beyond $150,000 at the top, with a $43,000 median. Sixty per cent declined to price the brief up front. Those figures cover product design across the whole benchmark, so treat them as the range SaaS design at Series B is quoted inside rather than a price for it.

Per hour. Quotes ranged from $25 to $195, median $55 to $90. Region explains almost all of it. Series B SaaS design sits above the median, because the work includes auditing what already exists, keeping two versions running through a migration, and shipping inside a release cadence somebody else controls.

The 57 agencies split 45% Time & Material, 35% fixed price, 20% retainer, and the right choice depends on how well you know the scope. For SaaS design at Series B the model usually matters more than the headline figure, because it decides what happens when the scope moves.

• Fixed price for bounded scope.
• Time & Material for evolving scope.
• Retainer for permanent design demand.
• Which one fits SaaS design at Series B comes down to whether the scope is settled before the work starts.

How do you evaluate a SaaS design agency for a Series B company?

Five things separate SaaS design at Series B from a first product build.

Ask how existing users get migrated. A redesign that ships on a Tuesday to people who learned the old layout produces a support queue. Ask what the rollout looks like, who sees it first, and what stays reachable.

Ask what they do with the features nobody uses. Three years of shipping leaves surface area that two accounts touch, and removing it is a commercial decision before it is a design one.

Ask how they design permissions for an enterprise buyer. Deals at this stage arrive asking for granular roles, audit trails and single sign-on, and those requirements reshape navigation rather than sitting quietly in a settings tab.

Ask whether they will work in your design system or replace it. Most companies at this stage already have one, half-finished. Replacing it spends engineering time nobody put in the plan.

Ask how they ship inside your release process. By now the constraint is not producing screens, it is getting them through a roadmap already committed two quarters out.

What are the red flags when hiring a design agency?

• Discovery priced as a separate product. Paying twice to be told what you already know is common and avoidable.
• A team that grows only after signature. Ask who is assigned now, not who could be.
• Metrics quoted without baselines. "Increased conversion 40%" from what, over what period.
• No process for disagreement. Ask what happens when you reject a direction twice.
• Silence on what they would not take on. An agency with no boundaries has no specialism.
• No comparable example of SaaS design at Series B. An agency that cannot point to work of the same shape is learning on your budget.

Should you hire a SaaS design agency or build in-house?

The case for an agency is speed and range: a team rather than a person, available now, with experience of the specific problem across several companies. For SaaS design at Series B specifically, the question worth settling first is how often the work recurs.

The case for hiring is accumulation. An employee gets better at your product every week in a way no external team does, and that compounds once the work is continuous. Where SaaS design at Series B falls on that line is usually clear once you count how many times it will need doing again.

By Series B there is usually a design team of three to six and a system that half exists. An agency earns its place on work in-house cannot absorb without stopping the roadmap: a full redesign, a second product line, or the design system nobody has had a clear month to finish. Hiring instead makes sense when the need is daily judgement across many small decisions rather than one bounded programme.

FAQs

What makes SaaS design at Series B hard?

Nothing can be redesigned in isolation. Customers have built process around the product and integrated it, so every change carries a retraining cost, and most of the work is reconciling three years of features rather than inventing anything.

How much does a Series B redesign cost?

Fixed-price product design across the benchmark ran $2,500 to over $150,000 with a median near $43,000, and retainers ran $7,000 to $20,000 per month. A staged redesign of a live product usually runs as a retainer. Bricx starts at $25,000.

Should a live product be redesigned all at once?

Rarely. Shipping surface by surface lets support absorb each change and lets usage settle an argument, though it costs more in total because two versions of the interface have to coexist for months.

What does an enterprise deal actually demand from design?

Granular roles, audit trails, single sign-on, and an admin who can answer for what everyone else did. Those requirements reshape navigation and object models, which is why they cannot be added late as one more settings page.
