Where to Start With Lead Generation for Professional Services Firms

I often see firms with 20, 30, or even 50 people that were built rapidly on the power of referrals, and eventually they hit a wall. Growth slows down, the pipeline runs dry, and leadership begins to question its own decisions.

Referrals still matter, but they are no longer enough to sustain growth. We're in a very low trust environment for services. People are getting spammed all day long now, and AI is just doubling that.

Key Takeaways

• Past clients are the first place to look for new work.
• Firms that serve the same buyers you do are the best source of referrals after past clients.
• Clients are easier to find when you're specific about the work you do and who it's for.
• Cold outreach only works when you have a fantastic offer.

Where do professional services firms get their leads?

More leads come from referrals than from anywhere else. The Hinge Research Institute's 2026 High Growth Study of 495 professional services firms found referrals were the largest single source of leads, followed by sales and direct outreach. In SparkToro and Paddy Moogan's 2024 survey of 612 agency owners and consultants, 66 percent said their top source of referrals was existing and past clients, and partner companies came second at nearly 13 percent.

If cash flow is a problem, the first thing you do is go back to past clients, because the easiest way to get cash is from people who've given you cash already. The second fastest way is to have somebody refer you. The third way is cold outreach. You need to be doing all three.

Why should a firm start with past clients?

People who already wrote you a check are more likely to write you another one than brand new people. Go back to those folks and say you're checking up. Ask what they liked about working with you, what they thought of the project, and how it did for them.

Past clients came to you for one thing, and they don't know the rest of what you do. If I still had access to a past client's analytics, I'd go in and tell them it looks like traffic is dropping in these areas, and maybe it's time for a refresh. They'd thank me for looking out for them, even if it didn't turn into business.

A short note works too. "We enjoyed working with you on that project. I'm looking for some feedback on this new offering we've got. I thought of you, and I'd love to hear your thoughts on it."

How do partner firms send you work?

At the agency I ran, referral partnerships were more than a third of our income.

A friend at the pub might like you a lot, but he doesn't know what you do, so he wouldn't know what to listen for. Firms in spaces adjacent to yours, with the same buyers, know exactly what to listen for.

One way to start is to join other people's parties with yours. Find firms in adjacent spaces that have the same target audience, reach out, and say you're starting a webinar series and you'd love to have one of their people join you to talk about best practices. They get excited because they're going to be introduced to your audience, and you get introduced to theirs.

A lot of referral partnerships don't work very well, because people sign the agreement and assume the contract is going to do the work. A partnership needs a rhythm of regular touch points, and a different excuse each time for why you're reaching out.

How does a firm get known for something specific?

Whenever you're meeting somebody new, tell them what you did. People remember stories. If you just say you do analytics and automation, people are like, who? It works better to have a couple of little anecdotes that describe a solution: here was the problem, here's the impact of the problem, and here's what I did to fix it.

A new contact asked me what I do. I said I'd just gotten off a call where one of my clients said she wasn't going to let me go. I didn't even tell him what I do. He said, "I gotta know more."

Being good at a lot of things is a problem a lot of firms run into, because then people don't know what you're good at. The more specific you can be about the type of work you want to do, and for who, the better chance you have to find clients.

A lot of firms start with "I want to work with medium sized businesses." The problem is there are a million of those out there, and trying to attract a million people is very challenging. If you niche down to something like custom software development for SaaS companies that work with medical devices, it's much easier to find them and grab their attention.

Owners always worry that naming a niche will scare off everyone else. Just because you say you work with fintech companies doesn't mean you're only going to attract fintech companies.

Does cold outreach work for a professional services firm?

Cold outreach only works when you have a fantastic offer.

SparkToro's State of Digital Agencies 2025 found 59 percent of agencies had tried outbound sales. Of those who tried, 9 percent called it very effective and 33 percent called it not effective at all.

Spam works great when you're selling cheap things, and a firm like yours sells expensive things. You're at the Mercedes dealership. The used car dealership down the road is the one that lives by volume.

People's inboxes are full, but their mailboxes are empty. One way I reach people I don't know yet is to mail them a book with a note.

On LinkedIn, a blind "I'd love to connect" request is the lowest form of outreach. The best form is you view the person's profile, a day or so later you comment on something they posted, and a day after that you send the connection request. It doesn't feel like a bot. Be very clear about your ask in the connection request, because that's how you build trust with people.

Should a firm host its own events?

Early on at the agency I ran, I had no experience bringing in new clients. I tried gift cards, I tried everything, and nothing worked. My dad always taught me that when the invitations stop coming, you throw your own parties. That's when I started throwing mine.

You're never as important as you are when you host the party. Stop just going to events and start throwing them. It can be a little panel at the brewery in town on AI and medical devices, where a couple of people you met through networking speak, you invite people, and you're the host.

Invite past clients, warm contacts and decision makers, plus their teams. These events are community credibility builders, because you're showing people what it's like to work with you in a formal setting.

One owner I work with had space he wasn't using and started hosting a monthly creative jam there. He posted about it, and that's where his next client came from.

How does Schmidt Consulting Group help a firm build lead generation?

Schmidt Consulting Group works with founder-led agencies and professional services firms on positioning, pricing and new business.

Mentorship is twice-monthly counsel for founders on pricing, hiring, clients and direction. You set the agenda, and your team does the work.

Advisory is a weekly operating rhythm for growth: a written plan, one priority at a time, and a review of results every week.

A two-founder production studio worked with us twice a month, and the list of companies they built in those sessions got them a meeting with Google.

You'll hear the fee on our first call. If your referrals have already slowed, start with what to do first when agency referrals dry up. For the wider plan, read go-to-market strategy for professional services firms.
