Keep Follow Up Boss? When yes — and when it isn’t enough.
Follow Up Boss is a respected lead-routing CRM in real estate — and it has been owned by Zillow Group since November 2023. Espo sits where FUB stops: an owned, AI-readable website, ads on your own account, an assistant inside the CRM, and listing proof that stays with your brand.
Credit where it is due
What Follow Up Boss does well.
If your problem is “we have leads but our CRM doesn’t get used and we can’t see who’s working what,” Follow Up Boss is hard to beat. We say this honestly.
A fast, simple interface agents actually open — Capterra reviews consistently call out adoption.
250+ integrations with Zillow, Realtor.com, Homes.com, Ylopo, Sierra Interactive, BoomTown, and Real Geeks.
Strong in-app calling, texting, and email, with per-agent recording and transcription.
Documented results at scale — Robert Slack’s team, Ashton Real Estate Group ($1B in sales), and 19,000+ teams on the product.
They built a great product, and a lot of teams are happy with it. If you already have a strong lead source and a marketing team that’s working, FUB does its one job extremely well.

The boundary
Where Follow Up Boss stops.
Follow Up Boss is a great car with no gas. It organizes the leads you already have and routes them well. Five gaps a complete real-estate stack still has to fill:
Zillow owns the parent company
FUB was acquired by Zillow Group in November 2023. The November 2025 TOS update permits Zillow to use data on “mutual customers” — clients who exist in both FUB and Zillow — for marketing, UX, and AI training.
No website or IDX
FUB doesn’t build websites. You still need Sierra Interactive, Real Geeks, or Ylopo at roughly $300–$1,500/mo more — and none of them are built as an AI-ready site on a domain you own.
No ad management
Per their own pricing FAQ: “Follow Up Boss is not a real estate lead provider or website company.” FUB doesn’t run ads at all — add an agency at $2–5K/mo to fill the gap.
Reporting stops at the lead
Lead-source reporting and FUB Pixel handle source attribution. Following the source through stage and deal value isn’t native.
The AI is shallow
Smart Summaries and Suggested Tasks are inline helpers, not a tool-calling assistant that does the work. Capterra, verbatim: “The AI component is helpful but needs work. It often isn’t accurate.”
Add FUB, a website vendor, an ad agency, and a listing videographer and you’re in the typical industry ranges — $5,100–11,400 a month across five vendors — with Zillow watching the leads you work. Espo Growth Partner is one engine at $2,500/mo for up to 10 agents, on infrastructure that stays yours. We’re not claiming exact savings; the ranges are there so you can do your own math.
The difference
What Espo adds around it.
Espo isn’t a competitor to Follow Up Boss — it’s the engine FUB doesn’t include, on infrastructure that stays yours:
If you love your FUB instance, keep it for the lead-routing layer while you’re getting started. The difference is what’s wrapped around it — and who owns the data inside.
No automatic answer
Which fits the job now?
Choose Espo if…
- Want your own name to be the address buyers, sellers and AI can find — an AI-ready site on a domain you own, not a brokerage profile.
- Want a listing to do more than a flyer: page, video, open-house QR and a campaign on your own ad account, live in about 21 days.
- Want a CRM your agents actually run — by talking to it from a phone — with the assistant, phone lines and recording in one place.
- Want your client data independent of any portal, and your data out within 48 hours if you ever leave.
- Run a team of up to 10 agents and want one decision to give every included agent the full stack.
Choose Follow Up Boss if…
- Already have a strong lead source and a separate marketing team that’s working — you need routing, not an engine.
- Are comfortable with Zillow Group as the parent company of your CRM.
- Want a best-of-breed stack you assemble and drive yourself, with 250+ integrations to choose from.
- Don’t need help with a website, ads, source-to-deal reporting, or listing launches — and don’t want to pay for them.
Straight answers
Questions about Follow Up Boss.
Is Follow Up Boss owned by Zillow?
Yes. Zillow Group acquired Follow Up Boss in November 2023 for $400–500M cash. In November 2025, Follow Up Boss updated its Terms of Service and Privacy Notice to grant Zillow use of data on "mutual customers" (clients who exist in both FUB and Zillow) for marketing, UX improvement, and AI training. "Agent-only contacts" — people who exist solely in your FUB CRM — remain off-limits to Zillow. The change drew significant agent backlash, with public coverage from RISMedia, BAM, and HousingWire. If you are uncomfortable with your CRM being owned by the largest portal in your industry, factor that in.
Will my client data be used to compete against me?
On Follow Up Boss, the November 2025 TOS update permits Zillow to use data from "mutual customers" — your clients who already have a Zillow account — for marketing, UX, and AI training. Zillow has stated agent-only contacts (people only in your FUB) are off-limits. Whether that line holds long-term is a judgment call every team has to make. Espo is independently owned with no portal parent company; your client data is yours alone.
Is Follow Up Boss a bad CRM?
No. FUB is widely regarded as the best standalone CRM in real estate, and we say so on this page. The lead-routing engine (round-robin, first-to-claim, ZIP/price/source rules) is the category benchmark, and the open-ecosystem philosophy with 250+ integrations is a real strength. The trade-off is that FUB is a CRM only — it does not build websites, run ads, or connect source-to-deal reporting. A complete real-estate stack with FUB at the center typically requires 2–3 more vendors (website, ads, transaction management) at $4K+/mo combined.
Is the $69/user Grow plan actually $69?
Effectively $108/user once you add the Calling add-on ($39/user), which most real-estate workflows require for the dialer, call recording, and many AI features. A 5-seat team on Grow with Calling = $540/mo on monthly billing. The Pro plan at $499/mo flat (10 users included, calling included) becomes cheaper at 5+ heavy-calling seats. The top FUB tier is $1,000/mo for 30 users with priority support. None of those plans include ads, a website, or managed marketing — those still require separate vendors. (FUB pricing as published, August 2026.)
What does Follow Up Boss not do that I'll have to buy elsewhere?
Websites and IDX (typically Sierra Interactive, Real Geeks, or Ylopo). Ad-campaign management. Transaction management (Dotloop, SkySlope). AI-generated video and listing-marketing assets. Per-listing landing pages with QR open-house flow. Source-to-deal reporting when the required campaign, stage, and deal-value inputs are connected. FUB's stated philosophy is best-of-breed integrations, not all-in-one — which means the bill at scale is FUB plus several other vendors. Espo's Growth Partner brings the operating stack together and runs managed Meta ads on your own ad account.
Can I use Follow Up Boss alongside Espo?
Espo includes its own real-estate-purpose-built CRM, so running both creates the same fragmented stack Espo is designed to replace. That said, you own all your data — we can export your contacts, deals, and pipeline state to FUB or anywhere else, your data out within 48 hours, no questions asked. Most teams that move to Espo retire FUB during the build (about 21 days) because the lead-routing, the assistant, and per-agent calling are all in one system instead of two.
