Choose a niche by picking a group of clients you understand, who can pay your fee, whom you can reach, and whom few other firms claim. The last test is the one most advisors skip, and our data makes it easy to check. On the 1,670 fee-only firm websites where we verified specialties, retirement planning appears on 63%, tax planning on 58% and estate planning on 43%. Equity compensation appears on 18%, founders before an exit on 7%, and crypto on 1%. It pays to be specific: Kitces Research found high-growth practices under $1 million of revenue were more likely to be niche-focused, 56% against 41%.
A niche is a client, not a service
Retirement, tax and estate planning are services. Nearly every fee-only firm offers them, so they tell a prospect you’re competent, not that you’re for them. A niche names who you serve and the situation they’re in: “physicians in their first ten years of practice”, “tech employees with stock options”, “couples where one spouse is Canadian”.
Kitces Research uses a strict test. A practice counts as niche-focused only if at least 75% of its new clients in the past year fit its target market, across up to three niches. If a firm says it serves dentists but most new clients aren’t dentists, the niche isn’t shaping the business.
Which specialties are crowded and which are rare
We read the specialties each firm describes on its own website and kept only those backed by a quote we found word for word on the page.
The field sorts into three groups:
- Crowded: retirement, tax and estate planning. Treat them as the floor, not a position.
- Contested: small business owners (23%), equity compensation (18%) and flat-fee planning (11%). Real niches, with enough firms in them that you’ll need a sharper angle, such as “equity pay at pre-IPO companies” rather than “equity compensation”.
- Rare: founders before an exit (7%), crypto (1%) and concentrated stock positions (1%). Divorce planning, student loans, pension decisions, physicians, real estate investors and cross-border families each appear on fewer firm sites than founders do. The full breakdown is in the website study.
Of the sites we read, about 4 in 10 name no specialty beyond retirement, tax or estate planning. That’s the gap: a firm that names a real niche in plain text is already in the minority.
One caution. These figures measure supply, how many firms say they serve a group. They don’t measure demand. A rare specialty can be rare because few clients need it. For underserved specialties and states in more detail, see underserved niches for fee-only advisors.
What a niche is worth
The Kitces Research 2026 marketing study measured the payoff in several channels:
- Referrals. Practices with a clear niche spent $0.06 per $1 of new revenue from client referrals, against $0.24 for practices without one. Among niche practices, those that said so prominently on their website did better again: $0.06 against $0.13, and 5.0% referral-driven client growth against 4.1%. Kitces’ explanation is that a client who knows exactly whom you serve recognizes the friend who needs you.
- Search. Niche practices had meaningfully higher success rates from SEO, a gap that widened from the 2024 edition. Kitces’ summary: “SEO rewards specificity.”
- Centers of influence. 37% of high-growth practices used professionals tied to their target market, such as a doctor at the hospital whose staff they serve, against 21% of other practices.
- Small firms most of all. Niche-focused practices were overrepresented among high-growth firms up to $1 million of revenue, after which the pattern weakened. A firm’s brand takes over as it grows; until then, the niche is the brand.
AI assistants work the same way. In our study of 600 AI answers, rewording the question changed most of the list: lists for the same city overlapped by only 28% across phrasings. Clients describe their situation, and the firm whose pages match that situation is the one that can be named.
Five tests for choosing one
1. You understand it from the inside
The best niches come from your own history: a past career, a family situation, the clients you already enjoy most. A former engineer understands RSU vesting schedules without studying them. Look at your favorite five clients and ask what they have in common.
2. They can pay your fee
The median ongoing planning fee among fee-only firms that publish prices is $4,500 a year (middle half $2,400 to $7,200) (fee report). Check that your target clients can pay a fee in that range without strain. Teachers, residents and early-career professionals can be excellent niches, but usually with a lower fee, a one-time plan or more clients per advisor. Price for the niche: see how to price financial planning.
3. You can reach them
A niche needs places where its members gather and people who advise them. Physicians have hospitals, residency programs and specialty associations. Divorcing clients have family-law attorneys and mediators. If you can’t name three groups or professionals who already serve your niche, it will be hard to market to.
4. Few firms already own it
Use the chart above as a national check, then look locally. The specialty pages in the public graph at find.wellspent.co, such as equity compensation, divorce planning and physicians, show which fee-only advisors claim each one and where they are. If a specialty is already crowded where you are, narrow it or pair it with a second dimension.
5. You can say it in one sentence
“I help federal employees decide when to retire and what to do with their pension” passes. “I help families achieve their financial goals” doesn’t. If the sentence works, it goes on your homepage, your fee page and every record you keep elsewhere.
Combine a group with a situation
The strongest niches pair who the client is with what they’re going through: physicians selling a practice, tech employees before an IPO, retirees with a pension lump-sum decision. Kitces’ definition allows up to three niches, so a firm can serve “small business owners” and “founders before an exit” without contradiction, because the second grows out of the first.
Location can be a niche too, if your area is underserved, but most rare specialties need a wider net than one town. Of the sites we read, 29% say they work with clients virtually. Serving a national niche by video is now ordinary, and it’s how a narrow focus finds enough clients.
Make the niche visible
Kitces found that saying the niche prominently on your site is what turns it into referrals. Practically:
- Name it on your homepage, in your clients’ words.
- Give it its own page that answers the three questions those clients ask first.
- Publish fees that fit it. Only 52% of fee-only firm sites state any price we could verify (publish your fees).
- Tell your existing clients, in one sentence, whom you’re best for.
- Keep the same specialties on every outside record, so search engines and AI assistants find one consistent story.
Choosing a niche is part of launching a firm, so it’s step one in starting an RIA with no clients.
Where Wellspent fits
A niche works when the people in it can find you. A Wellspent record in the public graph at find.wellspent.co shows your specialties, the clients you serve and your fees, verified and organized so a search for that niche, or an AI assistant answering it, can name you. Prospects write to you directly, with no lead fees and no share of client fees. Members also get a monthly report on who AI assistants recommend for questions their ideal clients ask, and quarterly press placement with media partners, matched by specialty. It’s $89 a month. See how it works.
