Fello vs ACE for finding sellers: Both surface likely sellers hiding in your existing database. Fello is a dedicated seller-lead-generation platform — a proprietary propensity model, homeowner home-value pages as lead magnets, and automated outreach you run alongside your CRM. ACE builds the same likely-seller scanning into the Follow Up Boss you already run: a nightly Seller Radar that scores propensity across 30+ third-party data sources (ownership tenure, estimated equity, local appreciation, area-risk overlays), then drafts reactivation touches the agent reviews and sends. Fello is a paid seller engine with proprietary data and hands-off outreach; ACE is an AI layer inside FUB with a broad third-party data network and human-in-the-loop sends — plus lead scoring, revenue-at-risk, and Fair Housing compliance in the same product.
What is Fello?
Fello is a real estate marketing and database-engagement platform focused on seller lead generation. Its core promise is to find the homeowners in an agent's existing database who are most likely to sell, using a proprietary seller-propensity model, and to keep those homeowners engaged with home-value tracking and automated outreach.
According to Fello's public product materials, the platform centers on a few things: a seller score / "Real Sellers" model that ranks likely sellers in your database; homeowner home-value pages that act as lead magnets and keep owners checking their estimated value; and automated outreach (email, direct mail/postcards, and an AI assistant) that nurtures those homeowners over time. Fello integrates with common CRMs — including Follow Up Boss — to sync contacts and scores.

What ACE's Seller Radar does — and how it's built
Follow Up Ace is an AI layer for teams already on Follow Up Boss. One module of it, Seller Radar, addresses the same job Fello does: surfacing likely sellers already sitting in your database.
Every night, an account-wide scan reads your Follow Up Boss contacts and, for the dormant ones, enriches each home address against a network of third-party data sources and scores propensity to sell. The score is built from:
- Ownership tenure — years since the last recorded sale (the dominant driver; homeowners near the typical move window score higher).
- Estimated home equity — modeled from purchase price, tenure, and local appreciation using a conservative mortgage assumption, and always labeled an estimate.
- Local price appreciation — from the FHFA House Price Index at the tract level.
- Area-risk overlays — county mortgage-delinquency pressure, FEMA flood, and wildfire/seismic flags from federal datasets.
- CRM seller signals — seller-, listing-, valuation-, downsizing-, or relocation-related tags already on the FUB contact.
The top likely sellers per agent appear in the Seller Radar dashboard with the evidence behind each score, and the scan drafts a reactivation message for the highest-scoring contacts that lands in the agent's suggestion queue. The agent reviews and sends — Ace does not auto-send seller outreach.
The honest part — equity is an estimate, not observed lien data. Ace blends more than 30 third-party data sources — county property records across 25+ states, the FHFA House Price Index, and nine federal datasets (FEMA, USFS, USGS, CFPB, Census, HUD). Home equity, though, is modeled from purchase price, tenure, and appreciation, not pulled from lien-level records, and we mark it "(est.)" everywhere it appears. Ace also does not detect life-event signals (divorce, probate, etc.). If you need observed lien data or life-event triggers, that's a real Fello edge.

The real difference: a dedicated seller engine vs seller intelligence inside your CRM
Fello and Ace agree on the premise — your next listing is probably already in your database — but they're built for different buyers.
Fello is a destination. It's a purpose-built seller-lead-generation platform: a proprietary model, branded homeowner value pages that pull owners back month after month, and automated outreach that runs largely hands-off. If seller lead gen is the program you're investing in and you want observed home-value data plus a lead-magnet funnel, that's exactly what Fello is for.
Ace is a layer. Seller Radar lives inside Follow Up Boss next to the rest of your follow-up, scores propensity across a 30+ source third-party data network, and hands the agent a drafted touch to approve — so the same product that finds the seller also scores your buyers, flags revenue at risk, and screens messages for Fair Housing. If you already run FUB and want likely-seller intelligence without standing up a second platform, that's the Ace approach.
When Fello is the right choice: Teams running seller lead generation as a dedicated program who want hosted homeowner home-value pages as a lead magnet, observed (not estimated) home-value/equity data, life-event triggers, and largely automated outreach — and are comfortable paying for a proprietary data model and running it alongside their CRM.
When ACE is the right choice: Teams already on Follow Up Boss that want likely-seller scanning built into the CRM they already use — nightly, across a broad third-party data network, with agent-reviewed touches — plus a full AI layer (account-wide lead scoring, Revenue Guard, Fair Housing compliance, voice, Claude/ChatGPT connectors) in one product. Start free; add the engine when you're ready.
Frequently asked questions
-
What is the difference between Fello and Follow Up Ace?
Fello is a seller-lead-generation platform: a proprietary propensity model, homeowner value-page lead magnets, and automated outreach you run alongside your CRM. Follow Up Ace is an AI layer for teams already on Follow Up Boss; its Seller Radar module scans your FUB database nightly for likely sellers across 30+ third-party data sources and drafts reactivation touches the agent reviews — alongside a broader AI Engine for lead scoring, revenue-at-risk, and Fair Housing compliance.
-
Does Ace find likely sellers in my database like Fello?
Yes. Ace's Seller Radar runs nightly and scores propensity to sell from ownership tenure, estimated home equity, local appreciation (FHFA House Price Index), area-distress overlays, and seller-related CRM tags. The top likely sellers per agent appear in the Seller Radar dashboard with the evidence behind each score. The main difference from Fello is the data model: Ace blends 30+ third-party data sources and labels modeled figures as estimates, rather than a single proprietary paid model.
-
Is Ace's home equity data as accurate as Fello's?
Be honest with yourself here. Ace estimates equity from purchase price, ownership tenure, and local FHFA appreciation using a conservative mortgage model, and marks every figure "(est.)" — it does not read lien-level records. A platform with paid home-value/lien data can be more precise on a given property. Ace's trade-off is breadth and transparency: you see exactly which signals drove each score, and equity is one weighted factor among several, not the whole story.
-
Does Ace auto-send seller outreach like Fello's automation?
No, by design. Ace drafts a reactivation message for the top likely sellers and places it in the agent's suggestion queue to review and send. Automated sends elsewhere in Ace pass a code-level Fair Housing compliance scan before delivery. The human-in-the-loop default is a deliberate choice for compliance and brand control; if fully hands-off outreach is a requirement, that's a Fello strength.
-
Can I use Fello and Follow Up Ace together?
Yes. Fello integrates with Follow Up Boss, and Ace runs inside FUB, so a team could use Fello for hosted home-value pages and outreach automation while Ace adds in-CRM seller scoring, lead scoring, revenue-at-risk, and compliance. Many FUB teams, though, start with Ace's Seller Radar first to see how much seller intelligence they can get from the database they already have before adding a second paid platform.
