I’m a HubSpot Solutions Partner, so I’ll be upfront: I have a perspective on this. But I’ve also spoken to enough founders who made the wrong CRM choice to know that being honest about when Salesforce is the right answer serves everyone better than pure advocacy.
The short version: for most B2B companies under £10M ARR, HubSpot is the right choice. But there are exceptions, and the cost of getting this decision wrong is higher than most people realise — not just in licence fees, but in implementation time, admin overhead, and the inevitable migration cost when you eventually switch.
The Philosophy Difference
HubSpot and Salesforce are built on different assumptions about who will run them.
HubSpot is designed to be used by revenue teams. Sales reps, marketers, and founders can configure most of it themselves. The reporting is accessible. The pipeline management is intuitive. You can get a well-configured HubSpot up and running in a few weeks without external help if you know what you’re doing.
Salesforce is designed to be configured by specialists. It’s infinitely flexible — almost anything is possible — but unlocking that flexibility requires technical knowledge. You’ll need either an in-house Salesforce admin or a consultant to do anything beyond the basics. Custom objects, complex workflows, non-standard reporting — all require someone who speaks Salesforce.
This isn’t a criticism of Salesforce. It’s a statement of fact about what the product is. Salesforce is enterprise infrastructure. It’s extraordinarily powerful if you need what it offers. But most early-stage B2B companies don’t need infinite flexibility. They need something that works reliably, that their team will actually use, and that doesn’t require a developer every time a process changes.
The Real Cost Comparison
Let’s talk numbers, because the sticker price comparison almost always understates the gap.
HubSpot Sales Hub Professional starts at around £90 per seat per month. For a team of three, that’s roughly £270/month or £3,240/year. You can do a lot with that, including pipeline management, sequences, reporting, and basic automation. Sales Hub Enterprise — which includes more advanced features like custom objects, predictive lead scoring, and revenue attribution — runs around £120 per seat per month at current pricing.
Salesforce Starter is cheaper at the entry level — around £20–£25 per user per month — but the feature set is genuinely limited. Most B2B companies end up on Professional or Enterprise, which pushes the licence cost up significantly. Salesforce Professional runs around £75 per user per month; Enterprise around £150. But that’s before you add the tools HubSpot bundles in by default: email tracking, meeting scheduling, calling, basic reporting. Most of those need separate Salesforce add-ons.
Then there’s the implementation cost. A basic HubSpot setup can be done in-house or with a partner for £3,000–£8,000. A Salesforce implementation for a small B2B company typically runs £15,000–£50,000 for anything beyond vanilla, once you include data migration, custom object setup, and workflow configuration. And that assumes it goes smoothly.
And there’s the admin cost that nobody budgets for. HubSpot can be maintained by a RevOps-aware generalist. Salesforce typically requires a dedicated Salesforce admin — in the UK, that’s a salary of £40,000–£65,000 — or ongoing consultancy fees. For a company at £2M ARR, that overhead is a meaningful percentage of revenue.
When HubSpot Is the Right Answer
For the vast majority of B2B companies I work with — typically somewhere between £500k and £10M ARR — HubSpot is the correct choice.
It’s right when your sales motion is relatively straightforward, even if your deals are complex. It handles multi-stage pipelines, multi-touch attribution, and deal-level detail well. It’s right when you want marketing and sales on the same platform, because the native integration between HubSpot Marketing Hub and Sales Hub is genuinely better than Salesforce’s equivalent (which requires Marketing Cloud and additional configuration). It’s right when you want your team to actually use the CRM — HubSpot’s UX is meaningfully better, which sounds like a minor point until you’re three months into a CRM rollout and half your team is working around it rather than in it.
HubSpot also wins on speed. If you need a functional CRM in six weeks, you can have one. If you’re heading into a fundraise and need to show clean pipeline data, HubSpot can be configured quickly enough to be useful.
When Salesforce Genuinely Makes Sense
There are situations where Salesforce is clearly the right answer, and I’d be doing founders a disservice not to say so.
Complex enterprise sales with heavy custom objects. If you’re selling into large enterprises with intricate approval chains, non-standard deal structures, and integrations into complex systems (SAP, Oracle, legacy ERP), Salesforce’s flexibility genuinely earns its complexity premium.
You’re already in a Salesforce ecosystem. If your key systems, integrations, and team skills are all built around Salesforce, switching to HubSpot creates its own disruption. The question is always “right for this situation” not “right in the abstract.”
You’re planning to raise a Series B or beyond and your investors expect it. Some enterprise-focused investors view Salesforce as table stakes at certain stages. That’s arguably short-sighted, but it’s real.
You’re genuinely at £15M+ ARR with a complex multi-product, multi-team motion. At that stage, Salesforce’s customisation becomes genuinely useful rather than over-engineered.
The Hidden Cost Nobody Talks About: Migration
Here’s the conversation I have most often with founders who made the Salesforce choice too early: “We’re thinking about moving to HubSpot. How bad is it?”
The honest answer is: it depends on how much of a mess your Salesforce is, but it’s rarely quick or cheap. Data migration from Salesforce to HubSpot involves mapping custom objects, cleaning dirty data, rebuilding workflows, and retraining the team. A migration from a reasonably clean Salesforce to HubSpot typically takes 6–12 weeks and costs £5,000–£20,000 in consultant time, depending on complexity.
The founders who made the right choice initially don’t pay that. The founders who chose Salesforce because it “felt more enterprise” at £1.5M ARR often end up paying it two or three years later, in addition to the admin overhead they’ve been carrying the whole time.
The total cost of a premature Salesforce decision, over three years, is easily £100,000–£200,000 when you account for implementation, ongoing admin, and eventual migration. That’s not a number most people factor in when they’re comparing monthly licence costs.
The Decision Framework
Here’s how I’d approach it:
If you’re under £10M ARR, have a sales team of fewer than 15 people, don’t have highly complex custom object requirements, and aren’t already embedded in a Salesforce ecosystem — choose HubSpot. The flexibility Salesforce offers is flexibility you don’t need yet, and the overhead will slow you down.
If you’re over £10M ARR, have complex enterprise requirements, have existing Salesforce infrastructure, or have specific integration needs that HubSpot can’t meet — then Salesforce is worth the complexity.
When in doubt, start with HubSpot. It’s easier to migrate from HubSpot to Salesforce later (when you actually need it) than to migrate from Salesforce to HubSpot when you realise you bought more than you needed.
