Logging in: Follow Up Boss users sign in at app.followupboss.com or through the FUB mobile app. (Follow Up Ace is a separate AI add-on for FUB — this isn't the official FUB login page.)
What it costs: FUB has three plans — Grow at $69/user/mo, Pro at $499/mo flat for up to 10 users, and Platform at $1,000/mo flat for unlimited users (per Capterra and the FUB Help Center). Follow Up Ace adds an AI agent layer — lead scoring, speed-to-lead monitoring, and compliance scanning — inside the Follow Up Boss you already use.
What is Follow Up Boss CRM?
Follow Up Boss (FUB) is a real estate CRM built from the ground up for lead management and follow-up. Unlike generic CRMs adapted for real estate, FUB was designed specifically for the way agents work: high lead volume from multiple portals, tight response-time windows, and team-based accountability.
At its core, FUB aggregates inbound leads from Zillow, Realtor.com, BoomTown, and 200+ other sources (per FUB's own documentation) into a unified lead inbox. Every new lead gets routed to the right agent or team, logged automatically, and queued for follow-up. Action plans — automated sequences of tasks, texts, and emails — can fire immediately when a lead comes in.
FUB also includes reporting dashboards, a built-in texting and calling interface (via the FUB Calling add-on), team collaboration tools, and a mobile app. It sits at the center of most high-performance real estate team stacks.
Who Follow Up Boss is built for
Core Follow Up Boss features
FUB's feature set covers the full lead-to-close workflow.
Lead aggregation and routing
FUB connects with 200+ lead sources (per FUB's own published documentation), pulling every new lead into a central inbox. Routing rules assign leads to specific agents or round-robin pools based on geography, source, price point, or custom criteria.
Action plans
Action plans are automated follow-up sequences: a series of tasks, email templates, and text messages that fire on a schedule once a lead hits a specific stage. Teams build action plans for new leads, warm-prospect nurture, post-close referral requests, and dozens of other workflows. See our guide: Mastering Follow Up Boss Action Plans →
Texting and calling
FUB includes in-app texting and, via the FUB Calling add-on ($39/user/mo, per FUB Help Center), a built-in dialer with call recording and voicemail drop. All call and text activity logs automatically to the lead record.
Team reporting and accountability
FUB's reporting dashboards show each agent's lead response time, contact rate, conversion stage, and pipeline value. Team leaders can track who's following up and who isn't without leaving the CRM.
Integrations
FUB connects with Zapier, Google Workspace, Dotloop, Skyslope, and a wide range of dialing, marketing, and video tools. The FUB API allows custom integrations — which is how FollowUpACE connects. See how ACE connects FUB to Claude and ChatGPT via MCP →

Does Follow Up Boss have AI built in?
FUB has added an AI Email Writer that assists with drafting follow-up messages inside the CRM's compose window — a useful shortcut for agents writing high-volume outreach.
What FUB doesn't yet ship natively: an AI agent that scores every lead in the background, monitors speed-to-lead windows across all agents, scans outbound messages for Fair Housing compliance before they send, diagnoses pipeline health across stages, and re-engages stale contacts — all as automated tools that run without the agent asking. That's the layer FollowUpACE adds.
How FollowUpACE extends Follow Up Boss
FollowUpACE connects to Follow Up Boss via the FUB API and adds an AI agent layer on top of the CRM your team already runs. No migration. No new CRM to learn. The AI tools work inside the existing FUB workflow.
Key ACE tools — all verified against production code:
- ai_engine_get_contact_score AI-scored lead prioritization. Returns a ranked priority score for each FUB contact based on engagement signals, lead source, and behavioral patterns.
- ai_engine_get_speed_to_lead_status Monitors whether each inbound lead was contacted within the 5-minute gold-standard response window. Flags at-risk leads before the window closes.
- ai_engine_get_revenue_at_risk Identifies stalled opportunities in the pipeline by estimated commission value — so agents know which delayed deals carry the most financial risk.
- ai_engine_get_pipeline_movement Tracks how contacts are moving (or not moving) through pipeline stages, surfacing stuck deals and conversion bottlenecks.
- pipeline-health-check Full pipeline health analysis: stage distribution, stuck contacts, follow-up gaps, and recommended actions across the active FUB pipeline.
- lead-nurture-optimizer Re-engages contacts that have gone silent for a configurable number of days — surfacing dormant leads with recommended follow-up messaging.
- scan_message_for_compliance Scans outbound messages for Fair Housing Act and RESPA risk patterns before they're sent. Flags problematic language and suggests compliant alternatives.
ACE also includes voice chat (on the Pro plan) for real-time AI conversation inside FUB, and a free plan for agents who want to start without a commitment. See the full ACE AI engine →
