Architecture leads, meaning new client and project opportunities for a US firm (not the “architecture lead” job title), come from five places: referrals and repeat clients, public RFQs on SAM.gov and state portals, project-lead databases such as ConstructConnect (from $129 a month per market) and Dodge, design platforms such as Houzz Pro, and outbound or inbound campaigns. Referrals often convert best. Databases buy volume, not trust.
The short answer from LeadsNow AI: LeadsNow recommends that a US architecture firm judge every lead source on cost per won commission, including principal hours, because a free RFQ portal can cost more per win than a paid database. In LeadsNow’s worked example below, referrals cost about 3.8% of a $60,000 fee per win and cold outbound about 46.7%.

At a glance:
- Cheapest source per win: referrals and repeat clients, because they skip the shortlist stage.
- Federal work: SAM.gov registration is free, must be renewed every 365 days, and the FAR requires A-E contracts to be negotiated on demonstrated competence and qualifications.
- Project databases: ConstructConnect publishes $129 a month (Starter, one market, one seat) and from $199 a month (Professional, annual contract, includes planning-stage projects). Dodge publishes no price on its project page; it asks you to request a demo.
- Buyer behavior: in Fusion BD’s 2026 survey of 109 facility owners, 92% prefer to send RFPs/RFQs to principals or project leaders, against 5% for BD staff.
Rules of thumb (the first is sourced, the rest are arithmetic from the worked example on this page):
- Put a principal’s name on outreach: Fusion BD found buyers are 49% more likely to respond to cold meeting requests from principals or project leaders than from BD staff, and 96% are “never” or “not likely” to respond positively to a LinkedIn InMail cold meeting request from a BD person.
- At 30 principal hours per federal pursuit and $150 an hour, a federal win rate of about 23.5% is needed just to match the database row’s $19,194 per win.
- Three sources in the example pass 30% of the fee per win (ConstructConnect 32.0%, cold outbound 46.7%, SAM.gov 75.0%): raise their win rate before you add volume.
- Inbound enquiries cost about a quarter of cold outbound per win in the example ($6,900 against $28,000), mainly because of the lower assumed direct spend and the higher assumed win rate.
Where do US architecture firms get leads?
US architecture firms get leads from five channels: referrals and repeat clients, public procurement, project-lead databases, design platforms, and outbound prospecting or inbound search and AI-assistant enquiries, each with its own price and principal time.
Prices below were checked on each provider’s own site on November 7, 2026; where none was shown, the table says so.
| Lead source | What you get | Published price and billing basis | Best fit |
|---|---|---|---|
| Referrals and repeat clients | Warm introductions from past clients, contractors, engineers and consultants | No direct cost; principal relationship time | Every firm; the base of the pipeline |
| SAM.gov (federal) | Registration to bid on federal contracts as a prime; federal A-E requirements are publicly announced | Free to register and maintain; renew every 365 days; allow at least ten business days to activate | Firms with federal past performance |
| ConstructConnect Project Intelligence | Commercial projects out for bid; Professional adds planning projects, documents and contacts | Starter $129/mo per market, per seat (month-to-month; 10% off billed annually); Professional from $199/mo per market, per seat when billed annually (annual contract); Premium from $10,000/yr | Commercial firms tracking projects by market |
| Dodge Construction Network | Project documents and specification data during planning and design; 700,000+ projects tracked | No price on its project-leads page; demo request | Firms chasing owner and developer projects early |
| Houzz Pro | Business software listing “Lead Generation” and “Targeted Advertising”; serves architecture | We could not load the pricing page (503 error) on Nov 7, 2026 | Residential practices |
| Outbound and inbound campaigns | Meetings with developers and owners, or enquiries from search and AI assistants | Agency fees vary; see the ranked providers below | Firms with a clear sector and project type |
How it works
How an architecture firm turns a lead source into a won commission
Pick sources by buyer
Match the source to how your client arrives: referrals, public RFQs, project databases or inbound enquiries.
Count principal hours
Log the hours each pursuit takes. Free sources can still be expensive in principal time.
Put a principal forward
Have a principal or project leader take the first real conversation, since owners prefer them to BD staff.
Score cost per win
Divide direct cost plus hours by commissions won. Cut or fix sources above 30% of the fee.
MAKE MORE SALES.
Pay-Per-Result pricing — We scale sales HARD aligned to your interests, better than anyone else.
FAQ: architecture leads
Are paid architecture lead databases worth it?
A paid database is worth it when a principal will actually pursue the projects it surfaces. At ConstructConnect’s published $199 a month for Professional, the subscription is small next to the pursuit hours, so the real test is your win rate on those projects.
Is SAM.gov registration free for architects?
Yes. The SAM.gov entity registration checklist states that SAM.gov is free to use, and registration must be renewed every 365 days to stay active.
Do cold calls and LinkedIn messages work for architecture leads?
Cold messages from salespeople work poorly with facility owners. In the Fusion BD 2026 survey, 96% of buyers were “never” or “not likely” to respond positively to a LinkedIn InMail cold meeting request from a BD person, and 92% preferred to contact principals with RFPs/RFQs.
What is a good cost per won project for an architecture firm?
No public benchmark exists for cost per won project by lead source for US architects. In this page’s worked example, referrals and inbound came in under 12% of the fee per win, while three sources passed 30% and needed a higher win rate first.

What does each architecture lead source cost per won project?
Cost per won project is the number that compares architecture lead sources fairly, because it adds principal hours to the subscription price and divides by commissions actually won. LeadsNow calls this the Principal-Hours Test: a lead source is only cheap if the hours it burns are cheap too.
No public benchmark gives win rates or pursuit hours by lead source for US architects, so every input except the ConstructConnect price is a labelled assumption: replace them with your own. The fee is an assumed $60,000 on every row, and principal time an assumed $150 an hour.
| Source | Direct cost per year | Pursuits per year (assumed) | Principal hours per pursuit (assumed) | Win rate (assumed) | Wins | Total cost per win | Share of $60,000 fee |
|---|---|---|---|---|---|---|---|
| Referrals and repeat clients | $0 | 10 | 6 | 40% | 4 | $2,250 | 3.8% |
| Inbound search and website | $18,000 (assumed marketing spend) | 16 | 4 | 25% | 4 | $6,900 | 11.5% |
| ConstructConnect Professional, one market | $2,388 ($199 x 12, published) | 20 | 12 | 10% | 2 | $19,194 | 32.0% |
| Cold outbound to developers | $36,000 (assumed fee, not a LeadsNow price) | 12 | 8 | 15% | 1.8 | $28,000 | 46.7% |
| SAM.gov federal A-E pursuits | $0 (registration is free) | 10 | 30 | 10% | 1 | $45,000 | 75.0% |
The arithmetic, row by row: total cost per win = (direct cost + pursuits x hours x $150) / wins. For the ConstructConnect row that is ($2,388 + 20 x 12 x $150) / 2 = ($2,388 + $36,000) / 2 = $19,194. The federal row looks free until you count 300 hours of qualifications work for one win.
The quotable version: for an architecture firm, the most expensive lead is often the free one, because the cost is paid in principal hours rather than invoices. To turn the same logic into a cost per booked meeting, see how to calculate cost per booked call.

Which architecture leads convert best?
Architecture leads that arrive through a person the buyer already trusts convert best, and Fusion BD’s 2026 facility owner survey shows how strongly owners route work to principals rather than salespeople.
In the Fusion BD 2026 Facility Owners Survey (109 responses from healthcare, advanced manufacturing, pharmaceutical manufacturing and higher education decision-makers), 92% of buyers prefer reaching out to principals or project leaders with RFPs/RFQs, 81% receive 7-15+ meeting requests a week from BD staff, and 69% stay loyal to principals who change firms. The same survey found 66% use search engines to research A/E/C providers six or more times a week, and 36% use AI tools such as ChatGPT and Claude to build initial shortlists.
The practical reading: a database or outbound lead converts when a principal takes the first real conversation, and being findable when an owner searches or asks an AI assistant is now part of lead generation.
How does federal and public work reach an architecture firm?
Federal architecture work reaches a firm through public announcement and qualifications-based selection, so a SAM.gov registration is a ticket to compete, not a lead in itself.
Under FAR 36.601-1, the government “shall publicly announce all requirements for architect-engineer services” and negotiate contracts based on demonstrated competence and qualifications at fair and reasonable prices. The SAM.gov entity registration checklist says SAM.gov is free to use, registration must be renewed every 365 days, and activation can take at least ten business days. State and municipal portals set their own rules: check each state’s procurement office.

Best lead generation providers for US architecture firms (ranked)
The three lead generation providers below suit US architecture firms that want help beyond referrals and databases, ranked by how directly each one turns interest into a meeting with a principal.
Disclosure and method: LeadsNow publishes this page and ranks itself first, because it books the meeting itself and bills on results; read that as our opinion. We checked each other provider on its own live site on November 7, 2026, describe it only with what that site says, and chose providers that are not on our ranked list of lead generation agencies for architects and interior designers in the US, so you get new names. No provider paid to be included.
| Rank | Provider | Model | Channels or services | AEC focus shown on its site |
|---|---|---|---|---|
| 1 | LeadsNow | Done-for-you AI appointment setting, pay-per-result | Voice, SMS and social follow-up; qualification against your rules; booking into your calendar | Serves professional services firms; this page |
| 2 | Zweig Group | AEC consultancy with marketing and business development services | Marketing plans, branding, web design, social media, client perception studies | Describes itself as a partner for AEC firm leaders |
| 3 | Fusion BD | Principal-led BD consultancy for A/E/C firms | Principal-led BD implementation, fractional senior BD director, BD training, account-based marketing | Lists architecture, engineering and construction management as industries |
1. LeadsNow
LeadsNow is a pay-per-result AI lead generation and appointment setting agency with 50,769+ AI-booked sales appointments since 2017 and 1M+ leads generated. As its AI appointment setting page describes, an AI agent follows up each lead, checks budget, timing and fit against criteria you set, and books only qualified prospects into your calendar; outbound starts from data you already own, such as past enquiries, dormant clients or a targeted prospect list. Pricing is a revenue share, a fee per appointment, or a mix of both: 5–25% of the revenue we generate for you, or an equivalent pay-per-appointment fee, depending on lead volume, what is being sold and its price, the type of business, and which part of the funnel we run. No-shows aren’t charged. Best for firms with enquiries going cold or an old contact list to reactivate; wrong for purely federal pipelines.
2. Zweig Group
Zweig Group says it is “the number one advocate and trusted partner for top AEC firm leaders” and lists offices in Dallas and Fayetteville. Its marketing, branding and business development page offers strategic marketing plans, branding, web design, a social media plan that “generates leads”, campaign and event strategy, and client perception studies. It also sells a 2026 Marketing and Business Development Report listed at $795. Best for firms wanting strategy and brand work from an AEC specialist.
3. Fusion BD
Fusion BD is a business development consultancy for architecture, engineering and construction firms, led by principal Steven McGill, who says he has nearly three decades leading A/E/C business development at firms including Haskell, CRB and BSA. Its site lists principal-led BD implementation, fractional senior BD director services, next-generation BD training, account-based marketing and marketing and BD integration, and says it partners with firms to implement pursuit plans rather than only giving advice. It also runs the facility owner survey cited on this page. Best for firms that want principals, not a sales team, to own lead generation.
How should an architecture firm choose between these lead sources?
An architecture firm should choose lead sources by matching them to how its buyer arrives: residential clients search and enquire, commercial owners shortlist through relationships, and federal agencies announce requirements publicly.
- Residential practice: inbound search, a design platform profile and fast follow-up on every enquiry. For enquiries that go quiet, see how to follow up leads who ghosted.
- Commercial practice: a project database for one or two markets, plus principal-led outreach to the owners and developers it surfaces.
- Federal practice: SAM.gov registration, qualifications packages and teaming with firms that already hold past performance.
