Sierra Interactive vs BoomTown: Which Fits in 2027

Short answer: pick by how you want to buy

Sierra Interactive and BoomTown both sell IDX websites, lead capture and CRM follow-up to real estate teams, so the choice is mostly about how you buy and what you can verify before you sign. Sierra is easier to compare on paper. Its pricing page lists the solo-agent tier at Starting monthly price: $299.95 according to Sierra Interactive (2026), and the tier for growing teams starts at $399.95 per month on the same page. BoomTown's comparison page shows no package prices at all, so you cannot judge its cost until someone quotes you.

Pick Sierra Interactive if you want a published starting number, an organic-search website model, and a dialer and marketing automation in one subscription. Pick BoomTown if you are ready for a sales conversation and want IDX sites bundled with managed ad campaigns, with the ad budget priced separately.

Both companies have changed hands, and that matters before you sign. BoomTown is not independent any more: Inside Real Estate acquired it in January 2023, and according to RealTrends the combined company was set to reach Combined headcount: 700 employees (2023). Sierra Interactive joined ASG, a portfolio company of Alpine Investors, in October 2022, according to Alpine Investors (2022). I found no later ownership change for either company in the sources I checked. No product here has been renamed or discontinued: BoomTown still sells under its own name on a 2026 site, but the Inside Real Estate announcement says nothing about folding BoomTown into kvCORE, which it describes as its core platform.

Key Takeaways

• Sierra publishes starting monthly prices for two tiers. BoomTown publishes no prices and routes buyers to its sales line.

• BoomTown's comparison page shows seat counts by tier (2, 5, and 10 or 25 users) but not what any tier costs.

• Sierra sits inside ASG, an Alpine Investors portfolio company. BoomTown belongs to Inside Real Estate, which also owns kvCORE.

• Sierra's own help center says its Zapier connection is for creating new leads, not for full two-way syncing, so plan native API or manual work for updates.

• Third-party price listings for both vendors disagree with each other and with the vendor pages. Ask for a written quote that covers seats, setup fees and ad spend.

• A useful definition: an IDX website is a property search site built on MLS listings, and a lead platform bundles that site with lead capture and CRM follow-up in one vendor.

How we evaluated these two platforms

This is an informed buyer's guide built from public pages, not a hands-on trial. We weighted seven criteria by what a small team usually decides first: cost visibility, lead model, seat structure, CRM depth, integration openness, ownership stability and contract clarity. The weights are our judgment about buying risk, not measured performance, and you can change them to fit your business.

What each platform publishes: the feature matrix

The matrix below normalizes only what each vendor or a named reviewer states on a page we opened. A blank or "Not published" cell means we did not find the item, not that the vendor lacks it.

Sierra's product list comes from its own announcement page, which names the CRM, IDX and ad management products. Sierra's Zapier guide says Zapier "is primarily intended for creating new leads" and does not offer full two-way syncing. BoomTown's comparison page publishes seat counts and integration access by tier, but it shows no prices, no setup fees and no ad-spend figure.

Pricing: what is public and what is quote-based

Pricing checked October 19, 2026.

On Sierra's pricing page, the solo-agent tier is described as "For solo agents or small teams" and starts at $299.95 per month. The tier for growing teams, labeled Teams & Brokerages, starts at $399.95 per month. Both are billed monthly on that page. The page lists no included-user count, no setup fee and no add-on prices, so a complete cost needs a written quote.

BoomTown's comparison page shows no price for any package, and it lists Launch, Core, Grow, Advance and btPRO only as options to contact sales about. An independent review of the same page reached the same conclusion: according to Front Desk Review BoomTown "publishes no self-serve price (quote-only) as checked on 2026-09-27." Every BoomTown row below is therefore Quote-based.

Third-party directories list monthly figures for both vendors, and those figures do not match the vendor pages. Softabase's Sierra listing shows different plan prices than Sierra's own page, and it was "Pricing last verified: March 26, 2026." For BoomTown, according to Softabase the plan fee "includes ad spend management but not the ad budget itself" (last verified March 26, 2026). Use directory figures to frame questions for a sales call, not to set a budget. A realistic total for either vendor adds setup fees, the ad budget, and any pass-through charges the quote includes.

Figures worth checking before a sales call

Each figure below is repeated from the text above, and the sources sit in the paragraphs that cite them.

Sierra Interactive: best fit, limits and setup

Sierra fits a team that wants a published starting price, an organic-search IDX website, and CRM tools in one subscription. Its own product pages list a Real Estate CRM with a dialer, email and text marketing, marketing automation and Lead Engage, plus IDX websites and Google and Facebook ad management. Sierra's business history is also stable enough to read: Sierra staff at the 2022 sale: more than 85 according to Alpine Investors (2022), and the same release says the company supports thousands of agents and teams in over 400 North American markets.

The limits are the questions the public pages leave open. The pricing page does not say how many users a plan includes, what setup costs, or what the ad service costs. Its Zapier connection is limited: Sierra's help center says Zapier "can update some fields but is primarily intended for creating new leads," and that it does not perform bulk imports. For large uploads, Sierra points to its CSV importer.

Implementation runs through the Integrations Manager. By default only the Primary Manager can open it, each integration can be set up once per account, and a finished integration appears as a lead source in Lead Routing Rules. Sierra's integrations guide also warns that "an integration without a routing rule means leads arrive in Sierra but nothing happens to them." Budget time for the routing rules before go-live, not after. For custom work, Sierra lists its API for "developers or technical teams building custom integrations."

Sierra's positioning is organic search. Softabase describes Sierra as one that "stands apart by prioritizing organic search," which is a fair summary of the model, though the review site is a third party and the claim is a positioning statement rather than a measured result. Sierra's pricing page also describes its audience as "real estate teams in the US and Canada."

BoomTown: best fit, limits and setup

BoomTown fits a buyer who wants IDX sites tied to lead generation and managed ad services, and who is ready to negotiate a quote. Its comparison page shows that every listed package includes an IDX site with agent subdomains, and that integration access rises by tier. The smallest package is the one to check first: Smallest published package: 2 included users according to BoomTown (2026). Growing teams would look at the Grow package, which lists 10 or 25 users and all integrations.

The limits are mostly about price and ownership. The price is quote-only, so the same scope has to be priced across both vendors before you can compare them. The ad budget is separate from the software fee: the Softabase listing describes the fee as covering ad management, not the budget itself, and the BoomTown comparison page does not mention ad spend at all. Ask for the ad budget as its own line.

Ownership is the second limit. The RealTrends announcement names kvCORE as Inside Real Estate's core platform and says nothing about integrating BoomTown's products. BoomTown and kvCORE now share a parent, so the kvCORE vs BoomTown comparison is the natural next read if that overlap matters to you. If you are also comparing BoomTown with Cinc or Real Geeks, this comparison covers that decision.

On integrations, the comparison page lists Zapier and API Nation on Launch, adds GCal on Core, and lists all integrations on Grow. I could not find public onboarding or API documentation for BoomTown on the pages I opened, so ask for the implementation plan, the data-export terms and the support commitments in writing before you sign.

Who each one is for

Who this is for:

• Choose Sierra Interactive if you want a starting number before any sales call, an organic-search website model, and a dialer and marketing tools in one subscription, and you can confirm seats and add-ons in writing.

• Choose BoomTown if you are comfortable with quote-only buying, want IDX sites tied to managed ad services, and expect to grow into the Grow tier that lists 10 or 25 users.

• Skip either one if you need two-way sync through Zapier alone, since Sierra says its Zapier connection does not provide it.

Red flags: you need an add-on or setup price before signing and cannot get it; you expect the ad budget to be included in the software fee; or you cannot get an itemized quote that separates seats, setup and ads.

Where a workflow layer fits

A proposed US Tech Automations design would sit above whichever CRM you buy and handle the handoffs the CRM does not do well: checking lead source, assigning a named owner, and writing an exception log. Treat this as a configurable design, not a live deployment. The trigger is a new lead created in the CRM or arriving through a native integration. The action is a rule that checks source and response time, then assigns an owner. The output is a routing record in your system and a daily exception list for a person to review.

The prerequisites are API or export access to the CRM, a working connection for new leads, and a named person who approves reassignments before they go out. The Sierra detail matters here: because Zapier is built for new leads, a design that updates existing lead status depends on Sierra's native API rather than Zapier. US Tech Automations could configure the routing rule and the exception queue differently for each platform, so the same human review step survives a later change of CRM. For BoomTown, the design needs an integration tier that covers the tools you actually use, because the Launch package lists fewer integrations than Grow.

The real alternative for many small teams is stitching this together in Zapier, Make or n8n, or building it in-house. Zapier's help center shows what a configured setup can do: according to Zapier Help Zapier "will automatically replay any Zap run with an errored status," and you can filter runs by status and date range. Make and n8n can also carry run histories, retries and error branches when you configure them. What none of these tools gives you is ownership. Your team still designs idempotency so a lead is not assigned twice, sets escalation paths, controls who sees lead data, and maintains the flow when a CRM field changes.

Worked example: take a hypothetical six-agent team that receives 120 inbound leads a month. If 30% need a manual reassignment after first contact, that is 36 leads, and if a reviewer spends 2 minutes on each, the exception queue costs 72 minutes a month, or about 1.2 hours. If the team's operations records sit in HubSpot next to the CRM, a proposed design could listen for the ASSOCIATION_ADDED action from HubSpot's webhook guide as the signal that a lead has been linked to a new record and needs a routing check. The table below scales the same 30% and 2-minute assumptions to other volumes.

When NOT to use US Tech Automations: skip a workflow layer if you are a solo agent who needs one CRM, a website and follow-up emails, because the native routing and automation in either platform will be cheaper to maintain. Skip it if your lead volume is low enough that one person reads every new lead the same day, since the exception queue adds little. And skip it if your CRM cannot provide API or export access, because the design described above cannot be built without it.

Common mistakes when choosing

1. Comparing Sierra's starting price against a BoomTown quote. Sierra's figures are starting prices, and BoomTown's are not published. Line both up against the same written scope.

2. Assuming Zapier gives two-way sync with Sierra. Sierra's guide says it does not, so plan native API or manual updates for existing leads.

3. Turning on an integration without a routing rule. Sierra's guide says the leads arrive and sit there.

4. Trusting directory price lists. They disagree with the vendor pages and with each other.

5. Forgetting the ad budget. Both vendors' ad services carry a separate budget, and Sierra's ad service has no published price.

6. Skipping ownership questions. Both companies sit inside larger groups, so ask about support, roadmap and contract terms in writing.

Frequently asked questions

Is Sierra Interactive cheaper than BoomTown?

Sierra publishes starting monthly prices of $299.95 and $399.95, while BoomTown publishes none, so a like-for-like comparison is not possible from public pages. Ask both vendors for a written quote that covers the same seats, setup fees and ad budget.

Who owns BoomTown now?

Inside Real Estate acquired BoomTown in January 2023, and the acquisition announcement names kvCORE as Inside Real Estate's core platform. The BoomTown brand still runs on its own 2026 site.

Can Zapier fully sync Sierra Interactive leads?

No. Sierra's Zapier guide says the connection is primarily for creating new leads and does not provide full two-way syncing, so existing-lead updates need native API work or manual steps.

Does BoomTown's package price include ad spend?

No. The BoomTown comparison page does not mention ad spend, and review sites describe the ad budget as separate from the software fee, so confirm it as its own line in any quote.

Do I need a separate workflow tool if I buy one of these?

Not always. If the platform's routing rules and one working integration cover your handoffs, a separate layer adds maintenance you may not need.

Which one is better for organic search?

Sierra is the one positioned around organic search. Its IDX sites are described as built to rank, while BoomTown leans on paid ads, according to the Softabase review pages cited above and in the vendor descriptions.

Making the call

If you need a number before you talk to anyone, start with Sierra's pricing page and write down the seat and add-on questions it leaves open. If you want BoomTown, plan for a sales conversation and insist on a written quote that separates software, setup and ad spend. Either way, get the owner's roadmap and contract terms in writing, because both companies now sit inside larger groups.
