Base CRM became Zendesk Sell after Zendesk acquired it in 2018, and its mobile-first, calling-centric sales tool now lives inside the Zendesk ecosystem. If you're not on Zendesk Support or want a more independent, modern sales CRM, these five alternatives cover everything from high-velocity calling to Gmail-native simplicity.

Visit Salesflare →Base CRM launched as one of the sharpest mobile-first sales CRMs of its era — a clean interface, built-in calling, and a genuine focus on the working salesperson rather than the sales manager's dashboard. When Zendesk acquired it in 2018 and rebranded it as Zendesk Sell, the pitch became a unified customer experience: pair Sell on the sales side with Zendesk Support on the service side and give both teams one view of the customer. For companies already committed to Zendesk, that integration is the whole point, and it remains a reasonable, capable sales tool with solid mobile apps and calling built in.
But that same integration is why many teams look elsewhere. Zendesk Sell shines as part of the Zendesk ecosystem; on its own, it competes against sales CRMs that have out-invested it in pipeline design, automation, and email. If you're not running Zendesk Support, you're paying for a suite you're not using. And some teams simply want a more modern, independent, or better-priced sales CRM than a service company's second act. Below are five alternatives worth a serious look in 2026, each chosen for a specific reason people leave Base.
We weighted four things. First, sales-CRM strength as a standalone — how good the pipeline, deals, and forecasting are without any suite dependency. Second, calling and outbound, since built-in phone was Base's original edge and still matters to phone-heavy teams. Third, automation and integration depth — email, calendar, and workflow, where dedicated CRMs have pulled ahead. Fourth, price and simplicity, because plenty of teams leaving Sell want something leaner. No invented scores; what follows is opinionated analysis.
If you want Base's sales-first spirit without the Zendesk baggage, Pipedrive is the natural landing spot. It's a sales CRM built by salespeople around one idea: a clean, visual pipeline that shows every deal and its next action at a glance. Nothing about it is a service tool wearing a sales hat.
Against Zendesk Sell, Pipedrive matches the pipeline-and-mobile strengths and pulls ahead on usability and ecosystem — a large marketplace, strong email and calendar sync, and automation that's easy to set up without an admin. It's independent, so you're not paying for a support suite you don't use, and its pricing is friendly at the entry tiers. For a small-to-midsize sales team that just wants to run its pipeline well, it's the most direct and satisfying replacement.
Best for: sales teams that want a clean, independent, visual pipeline.
Close is the alternative for teams that sell over the phone — which was Base's original identity. It's built for high-velocity inside sales, with calling, SMS, and email all native to the CRM, plus Power and Predictive dialers and sequences that keep reps in constant motion. Where Zendesk Sell has calling, Close makes calling the center of gravity.
For an outbound or inside-sales team, that focus is the whole value: a rep can work a list, dial, log, text, and email without leaving one screen, and managers get activity and outcome reporting built around real selling motion. It's less of a fit for teams that don't live on the phone, and it sits at a mid-market price point. But if your reps' days are measured in dials and conversations, Close is the sharpest tool here.
Best for: phone-heavy inside and outbound sales teams.
HubSpot is the alternative when you want more than a sales CRM — a platform that grows from a free contact database into full marketing, sales, and service. Its free tier is genuinely useful, with contact management, deal pipelines, and email tracking, and its paid Sales Hub adds sequences, automation, and reporting that scale to real teams.
Compared with Zendesk Sell, HubSpot offers a similar "unified customer" promise but from a different center — inbound marketing and a vast ecosystem rather than support ticketing. That makes it the better pick if marketing feeds your pipeline and you want everything under one roof over time. The trade-off is that costs climb as you add hubs and contacts. But for a growing company that wants room to expand and a free on-ramp, HubSpot is the most flexible choice.
Best for: growing teams that want a free start and room to add marketing and service.
Freshsales is the well-rounded, well-priced alternative that quietly does most of what Zendesk Sell does for less. Part of the Freshworks suite, it pairs a solid sales pipeline with built-in phone and email, AI-assisted lead scoring and insights, and automation — a lot of capability at an approachable entry price, including a free plan for small teams.
Against Sell, Freshsales matches the built-in-calling angle and adds sharper AI and a cleaner modern feel, while undercutting it on price. And like Zendesk, Freshworks offers a companion support product (Freshdesk) if you eventually want the sales-and-service pairing that Sell sells — just as a separate, arguably stronger option. For value-conscious teams that want built-in phone and AI without a premium bill, it's a strong pick.
Best for: value-focused teams wanting built-in phone and AI at a low entry price.
Salesflare is the alternative for small B2B teams that want the CRM to do the data entry for them. It automatically pulls in contacts, companies, emails, meetings, and signatures from your inbox and calendar, building and enriching records so reps spend time selling instead of logging. It lives right inside Gmail and Outlook.
Where Zendesk Sell asks you to work in its app, Salesflare comes to where you already work and keeps itself current automatically — a genuinely different philosophy that pays off for lean teams without dedicated ops. It has pipelines, email sequences, and solid automation, and it's priced for small business. It's less suited to large, complex sales orgs, but for a small B2B team that finds most CRMs too manual, it's the easiest to actually keep up to date.
Best for: small B2B teams that want an automatic, inbox-native CRM.
Start with why you're leaving Base. If you simply want an independent, clean sales pipeline, Pipedrive is the most direct swap. If your team sells on the phone, Close is built for exactly that. If you want a platform that spans marketing and service with a free on-ramp, HubSpot fits. If you want built-in phone and AI without a premium price, Freshsales is the value pick. And if manual data entry is what keeps killing your CRM habit, Salesflare automates it away. The deciding question: do you want a focused sales tool, a phone-first machine, or a broader platform? That fork narrows it fast.

Zendesk Sell is a capable mobile-first sales CRM that makes the most sense inside the Zendesk ecosystem — and less sense outside it. The case for switching gets strong when you're not using Zendesk Support, want a more modern or better-priced sales tool, or need deeper calling or automation. Pipedrive is the clean independent pipeline, Close the phone-first machine, HubSpot the do-everything platform, Freshsales the value all-rounder, and Salesflare the automatic, inbox-native option. Decide whether you want focus, calling firepower, or breadth, and the shortlist picks itself.
