Should an MSP niche? The targeting maths
An MSP should niche its outbound long before it niches its brand — and the decision is arithmetic, not identity. Count the addressable companies in each candidate sub-vertical, estimate how many you can reach and convert in a year, and check the result supports your growth target before committing to anything. Most MSPs discover that a single niche is too small to bet the firm on, but exactly the right size for one campaign — which is why the sensible structure is parallel campaigns per sub-vertical, not a rebrand.
Why is niching such a fraught question for MSPs?
Because the generalist position feels safe and sells badly. "We support any business from 10 to 200 seats" describes most MSPs in any given region, which means procurement hears no difference and the conversation collapses to price per seat. The sector profile in Growth Systems by Industry: the UK B2B service firm map is blunt about the consequence: MSPs sell a genuinely sticky, contract-based service — high lifetime value, painful to switch away from — yet acquire clients through referral and reactive tendering because nothing in their positioning gives outbound anything to say. Niching fixes the message. The fear is that it shrinks the market. The maths below tells you whether that fear is justified.
What is the actual arithmetic?
Work it through per candidate niche, in one spreadsheet column each:
- Universe. How many firms of your target size exist in the sub-vertical, in the geography you can serve? UK company data makes this countable rather than guessable — accountancy practices, law firms, GP federations, housing associations are all enumerable populations.
- Reachable decision-makers. Assume you can identify and verify contact details for a majority of that universe, not all of it.
- Annual coverage. One warmed inbox sending 25–40 cold emails a day, in sequences of 4 emails over 14 days, works through roughly 150–250 new companies a month.
- Conversations. At around a 4% positive-reply expectation — below 3% means fix the campaign, not abandon the niche — 200 companies a month yields roughly 8 conversations.
- Clients. Apply your honest meeting-to-client conversion and your average contract value, and you have the niche's yearly revenue potential from outbound alone.
When a sub-vertical contains 400 addressable firms, then one campaign covers the entire universe in under two years and the niche cannot be your only engine. When it contains 4,000, then you have years of runway before saturation. That single number — universe size — settles most niching debates that otherwise run on anecdote.
Where does the value of niching actually come from?
Specificity compounds through the whole funnel. A niche campaign lets you name the sub-vertical's systems ("your PMS", "your case management platform"), its compliance pressures, its seasonality and its typical failure modes — and that specificity roughly does the work that testimonials and awards fail to do. It also concentrates operational learning: after fifty conversations with accountancy practice managers, your discovery questions, onboarding checklist and pricing all sharpen in ways a generalist's never can. This is the same mechanism by which consultants win work through a public point of view, examined in the consultant's personal brand as pipeline: the market rewards the firm that sounds like it has seen this exact problem before, because it has.
Why parallel campaigns instead of a full rebrand?
Because campaigns are cheap experiments and rebrands are expensive bets. Run two or three sub-vertical campaigns simultaneously — separate lists, separate messaging, same delivery engine — and let reply rates and close rates identify the niche that deserves the brand. When one vertical consistently outperforms on positive replies, meeting quality and deal size, then you have evidence worth repositioning around; until then, the generalist brand loses you nothing while the niched campaigns do the selling. The commercial comparison matters too: this entire apparatus — data, sending infrastructure, sequences across multiple verticals — costs a fraction of the £35k+ a year a business development hire commands, a comparison worked through properly in what a BDR costs vs what an outbound system costs.
What are the honest failure modes?
Three recur. First, niching on an unaddressable market — a sub-vertical you cannot list, reach or size, which turns the arithmetic above into fiction. Second, fake niching: changing the homepage headline while the outreach, offer and delivery remain generic, so the market notices no difference. Third, niching without follow-up capacity — narrow targeting produces fewer, warmer conversations, and a firm that lets them go cold has spent precision to buy nothing. Lead magnets and nurture assets built for the sub-vertical, of the kind covered in lead magnets that work for accountants, are how those warmer conversations keep moving between touches.
Run the numbers before the identity debate. The spreadsheet usually ends the argument in an afternoon.
