What happens when you replace a 48-hour response time with a 42-second one — and how we built the agent that did it.
When Meridian SaaS came to us, they had a conversion problem. Not a traffic problem — they were getting 300–400 inbound leads a month from paid search and content. The problem was response time. Their SDR team was small, working UK hours, and the average first response to a new lead was 47 hours.
Research from Harvard Business Review puts the optimal response window at under five minutes. After an hour, odds of qualifying a lead drop by 60 times. At 47 hours, Meridian was essentially handing warm leads to their competitors.
The agent runs on a webhook triggered by any new form submission — Typeform, HubSpot forms, or direct API. Within seconds of a lead coming in, it does three things in parallel:
First, it enriches the lead. Using the email domain, it pulls company data — headcount, industry, tech stack, funding stage, LinkedIn presence. This gives the agent the context it needs to have an intelligent conversation rather than a generic one.
Second, it scores the lead against Meridian's ICP. Their ideal customer was a Series A–C SaaS company with 20–200 employees and at least one revenue operations role. The agent cross-references enrichment data against these criteria and assigns a priority score.
Third, it sends the opening message. Not a canned "thanks for your interest" email — a personalised outreach that references what we know about the company and asks a single qualifying question relevant to their context.
Response time went from 47 hours to 42 seconds. Not 42 minutes — 42 seconds. The agent doesn't sleep, doesn't take lunches, and doesn't have a backlog.
Pipeline grew by 340% in the first quarter. This wasn't because more leads came in — it was because fewer leads went cold before a human ever touched them. The SDR team went from spending time chasing unqualified leads to spending time on conversations the agent had already warmed up.
Cost per qualified opportunity dropped by 58%. The agent costs a fixed amount per month regardless of lead volume. As volume scaled, the cost per lead kept falling.
It doesn't close deals. It doesn't handle objections beyond a certain complexity. When a conversation reaches a natural handoff point — a prospect asking for pricing, a demo request, or a question outside the agent's scope — it routes cleanly to the right SDR with a full conversation summary.
The handoff is the part most teams get wrong. They either hand off too early (wasting SDR time) or too late (losing the prospect's momentum). We spent two weeks tuning the handoff logic specifically for Meridian's process.
Speed is the most underrated part of lead conversion. An agent that responds in seconds isn't a gimmick — it's a structural advantage. The question isn't whether you should automate first response. It's whether you can afford not to.
