Sellium for B2B SaaS:qualified leads on WhatsApp, with replies in seconds
The lead you paid for on LinkedIn Ads won't wait for whichever SDR is on shift. Sellium answers inbound 24/7 in seconds, qualifies with BANT/MEDDIC and ICP scoring, and books the demo on the right AE's calendar, with everything synced to Salesforce or HubSpot and no added headcount.
How do you automate lead response and qualification at a B2B SaaS company?
You automate lead response and qualification at a B2B SaaS company by connecting an AI sales agent on WhatsApp to your CRM: the agent answers first contact in seconds at any hour, runs BANT, MEDDIC or MEDDPICC qualification in under 3 minutes with the playbook RevOps configures, calculates the ICP score against industry, size, timeline and current stack, books the demo on the right AE's calendar through Calendly, Chili Piper or HubSpot Meetings, and syncs the full conversation to Salesforce or HubSpot with custom fields and an executive summary. Human SDRs stop chasing forms: they get deals that are already qualified, with full context.
In B2B SaaS, response time is the variable that moves the funnel: according to James Oldroyd's Lead Response Management Study with MIT and InsideSales.com (2007), contacting a lead within the first 5 minutes, instead of at 30, makes it up to 100x more likely to connect, and no SDR team covers three time zones with that consistency. Sellium, the sales agent in the Vantegrate Suite, was built for that SLA: it handles the inbound that arrives on Tuesday at 11:42 a.m. and the one that arrives on Sunday at 2 a.m. with the same qualification quality.
The full picture of the sector (the five agents applied to ERP, CRM, Cybersecurity, Data/AI, Collaboration, Vertical SaaS and DevTools vendors) is on the B2B SaaS page.
The pain points of the inbound funnel in SaaS
We gathered them in dozens of conversations with CROs, VPs of RevOps and heads of demand gen at B2B SaaS vendors with 100 to 5,000 employees.
The paid lead waits hours for a reply
You pay for the click on LinkedIn Ads and the demo form takes more than a day to get an answer. The 5-minute window closed long ago: the lead has already talked to the competitor who replied first.
Scaling SDRs kills the economics
Covering three time zones with human SDRs inflates CAC payback: the fully loaded cost of an SDR in the US runs around USD 106-141K a year according to The Bridge Group. Qualification quality depends on how tired the shift is, not on the playbook.
Trials that die without anyone talking to them
A good share of trials never reach the aha moment. It isn't a product problem: nobody talks to them during the first 7 days, and trial-to-paid stays stuck at the sector median.
Pipeline coverage comes up short every quarter
With MQL-to-SQL stalled near the sector average, pipeline coverage falls below the 3-4x the industry treats as healthy, and every quarter the board hears the same explanation.
How Sellium handles it at a SaaS vendor
The agent's capabilities, mapped to the funnel's pain points: each one works with your playbook, your ICP and your CRM, not with canned answers.
Response SLA
First reply in seconds, 24/7
Sellium answers WhatsApp inbound in seconds at any hour, every day. The lead who comes in on a Sunday at 2 a.m. gets the same attention as the one on Tuesday at 11.
Consistent qualification
BANT, MEDDIC and MEDDPICC in under 3 minutes
Applies the qualification framework RevOps configures, with ICP scoring against industry, size, timeline and stack, always at the same quality, regardless of the shift or anyone's fatigue.
Frictionless demo
Books the demo on the right AE's calendar
Native booking inside the conversation with Calendly, Chili Piper or HubSpot Meetings, respecting round-robin by territory, vertical and segment (enterprise, mid-market, SMB).
Trial activation
Supports the trial for the first 14 days
For PLG flows it identifies PQLs with triggers from Amplitude, Mixpanel, Heap or Pendo, answers implementation questions without pulling in the CSM and hands off to the AE when the trial enters the conversion zone.
Attribution intact
Two-way sync with Salesforce and HubSpot
Creates or enriches Lead, Contact and Opportunity with the ICP score, BANT/MEDDIC fields and a conversation summary, notifies the AE owner in Slack or Teams and emits events to Snowflake or Databricks for multi-touch attribution.
Global coverage
Native multilingual support to run three markets
Detects the lead's language and replies in Spanish, Portuguese or English with the right regional variant: a single agent covers LATAM, Brazil and the English-speaking market.
From the LinkedIn click to a booked demo in 2 minutes
The full flow with the most expensive lead in the funnel: the one you paid for on a paid channel, who usually waits hours for a reply.
Tuesday 11:42 a.m.
The lead clicks the campaign
María, VP of People Ops at a 380-employee FinTech scaleup, clicks a LinkedIn campaign from an HR tech vendor and chooses to continue on WhatsApp. Sellium replies in 8 seconds.
11:43 a.m.
BANT qualification in 3 questions
The agent weaves the playbook questions in naturally: FinTech industry, 380 people, a focus on onboarding and a decision within the quarter by board mandate. No forms.
11:44 a.m.
ICP score and routing to the right AE
Sellium calculates an ICP score of 87/100 and determines that the deal goes to the US mid-market AE, according to the round-robin RevOps set up.
11:44 a.m.
Demo booked via Chili Piper
It offers María real openings on the AE's calendar and confirms the demo for the next day at 2 p.m. EST, with the invitation sent inside the same conversation.
11:45 a.m.
Everything synced to the CRM
The Lead lands in Salesforce with the ICP score, BANT fields and an executive summary; HubSpot fires the nurturing workflow and the AE gets a Slack alert with the full context.
Total: 2 minutes 14 seconds from click to booked demo, with zero human involvement. The same lead that used to wait a business day in a form queue shows up to the first call with qualification done and the AE prepared.

Public sector benchmarks, not our own results: every Sellium implementation is measured against a baseline agreed with the customer (time to first response, MQL-to-SQL, demos booked, trial-to-paid).
Secure AI agents that work with your data
Sellium talks to your leads and writes to your CRM: data no CISO at a SaaS vendor hands over lightly. That is why it runs 100% on Salesforce and Oracle Cloud Infrastructure, with those platforms' SOC 2 Type II and ISO 27001 certifications, GDPR alignment and the permissions you define. We don't claim anyone else's certifications: Vantegrate enables, the customer operates and certifies.
Frequently asked questions about Sellium for B2B SaaS
Can an AI agent replace my SDRs?
Can an AI agent replace my SDRs?
It doesn't replace them: it takes the part that doesn't scale off their plate. Sellium absorbs the 24/7 first response and the repetitive qualification (the part that depends on the shift and on fatigue), and the human team focuses on deep discovery and complex deals. The economics are clear: the fully loaded cost of an SDR in the US runs around USD 106-141K a year according to The Bridge Group, and covering three time zones means multiplying it.
How does it integrate with Salesforce or HubSpot without losing attribution?
How does it integrate with Salesforce or HubSpot without losing attribution?
With two-way sync: Sellium creates or enriches Lead, Contact and Opportunity with the ICP score, BANT/MEDDIC fields and a conversation summary, triggers workflows in HubSpot and emits conversation events to Snowflake, Databricks or BigQuery for multi-touch attribution. The technical details of the flow are in WhatsApp integration with Salesforce.
Does it work for PLG with free trials, or only for sales-led?
Does it work for PLG with free trials, or only for sales-led?
Both. In PLG flows it identifies PQLs with triggers from Amplitude, Mixpanel, Heap or Pendo when an account crosses usage thresholds, supports trial activation for the first 14 days and hands off to the AE in the conversion zone. For reference, the sector median trial-to-paid is 8%, and close to 30% when a card is required (ChartMogul, 2026): assisted activation goes straight at that gap.
What about WhatsApp compliance and Meta's policies?
What about WhatsApp compliance and Meta's policies?
Sellium runs on the official WhatsApp Business API with templates pre-approved by Meta, documented express opt-in, one-click opt-out and quality rating monitoring. On privacy (GDPR, CCPA/CPRA), the compliance posture is the one inherited from Salesforce or Oracle Cloud Infrastructure, and the data processing agreement is defined with each customer during implementation. The cost of the channel, which Meta charges per delivered message by country and category, is explained in how much the WhatsApp Business API costs.
