Early-Stage Pipeline Red Flags: Is Your Top-of-Funnel Lying to You?

by Mentor Group

Why your top-of-funnel might be lying to you

On most dashboards, the story starts well.

Plenty of new opportunities. Healthy-looking coverage. Conversion rates that don’t look disastrous.

And yet, when the quarter closes, very little of that early-stage promise turns into revenue. Deals seem to evaporate somewhere between “first contact” and “serious opportunity”.

The problem often isn’t a lack of demand. It’s that your top-of-funnel is lying to you – or more precisely, you’re reading an imbalanced, distorted early pipeline and mistaking it for real opportunity.

This article shows you how to spot that specific issue: the early-stage red flags that tell you your Stage 1 and Stage 2 numbers can’t be trusted.

If you want the wider picture, you can also read our pillar blog, How to Spot Pipeline Imbalance Across Stages (Before It Wrecks Your Quarter)”.

 

What early-stage pipeline imbalance actually looks like

At the top of the funnel, imbalance typically shows up as a mismatch between Volume, Value and Velocity:

  • Volume – lots of opportunities created, often more than you expected.
  • Value – impressive pipeline value attached to those opportunities.
  • Velocity – but very little of that volume and value actually moves into genuine mid-funnel stages.

On a snapshot report, your early stages look abundant. Over time, though, you see a worrying pattern:

  • Early-stage Volume goes up.
  • Conversion from Stage 1/2 to Stage 3 goes down.
  • A growing proportion of early-stage opportunities never progress; they simply age out or disappear.

That’s the core symptom of an unhealthy top-of-funnel – it inflates confidence without improving outcomes.

 

Red flag 1: High volume, weak progression

The first and most obvious warning sign is a crowded Stage 1/2 with very little movement to the next stage.

On paper, this looks like success: marketing and SDR teams are “feeding the beast” with more and more leads and opportunities. But when you look one level deeper, the story changes:

  • Conversion from Stage 1 to Stage 2 is falling.
  • Conversion from Stage 2 to Stage 3 is even weaker.
  • There is no clear improvement in win rate despite the extra volume.

What this usually means:

  • Anything that breathes is being turned into an opportunity, regardless of quality.
  • There is no consistent filter for what “belongs” in the pipeline.
  • Teams are rewarded on activity logged, not on qualified progress.

If your early-stage volume curve is rising while progression to the next stage is flat or declining, your top-of-funnel is almost certainly lying to you.

 

Red flag 2: Early stages full of non-opportunities

The second red flag is qualitative rather than quantitative: when you inspect a set of early-stage records and discover that many of them simply aren’t real opportunities.

Typical signs:

  • No clear customer problem or use case documented.
  • No confirmed buying role – just a contact who “showed interest”.
  • Engagement is one-sided (for example, a webinar attendee with no follow-up conversation).

In other words, you have leads dressed up as opportunities.

This is often driven by targets and incentives. If SDRs, BDRs or marketing teams are measured on the number of opportunities created, rather than on the quality of those opportunities, the early pipeline will swell with deals that should never have been there in the first place.

 

Red flag 3: Vague, recycled or missing next steps

Healthy early-stage opportunities have momentum. There is a clear, mutually agreed next step and a date by which it will happen. Unhealthy ones don’t.

When you review your early-stage pipeline, look closely at the “next step” and “next step date” fields:

  • Are they specific (for example, “Discovery call with Jane and finance on 14 March to agree shortlist”)?
  • Or are they vague (“Follow up”, “Check in”, “Touch base”, “Send info”) or missing altogether?

Red flags include:

  • The same generic next step being pushed forward repeatedly.
  • Multiple opportunities for the same account all sharing identical, non-specific next steps.
  • Opportunities where the next step date has been missed several times, with no change in stage.

A top-of-funnel full of vague, recycled next steps isn’t building a future pipeline. It’s preserving a fiction.

 

Red flag 4: Ageing opportunities at Stage 1 and Stage 2

Time is one of the most honest indicators of pipeline health. If early-stage opportunities are staying there far longer than they should, something is wrong.

Practical checks to run:

  • Compare the average days in Stage 1/2 for opps that eventually convert, versus those that don’t.
  • Count how many current Stage 1/2 opportunities have been open for more than twice the typical early-stage duration.
  • Look at the distribution: do you have a long tail of very old early-stage opportunities?

If a significant proportion of early-stage deals are older than your normal full sales cycle, the top of your funnel isn’t a funnel at all. It’s a warehouse.

Those opportunities are unlikely to miraculously reactivate. They’re inflating your confidence, not your revenue.

 

Red flag 5: Source and channel distortion

Sometimes the problem isn’t that your early stages are busy; it’s that they’re busy with the wrong kind of demand.

A closer look at the source or channel fields can highlight this:

  • One or two channels (for example, a certain event type or partner) create a lot of early-stage opportunities but have very low conversion into mid-funnel stages.
  • Other channels create fewer opportunities, but with consistently higher progression and win rates.

When you aggregate everything together, the early stages look strong. But once you break it down by source, you realise your pipeline is being skewed by a small number of noisy, low-quality channels.

Left unchallenged, this can drive the wrong investment decisions – more money into activities that create top-of-funnel noise, not qualified opportunities.

 

A simple 30-minute audit of your early stages

You don’t need a huge analysis project to understand whether your top-of-funnel is lying to you. Set aside 30 minutes and run through these checks:

  1. Shape check (Volume and Value)
    • How many opportunities sit in Stage 1 and Stage 2?

    • What percentage of total pipeline value do they represent?

    • How does that compare to a previous quarter?
  2. Progression check (conversion)
    • What percentage of Stage 1 opportunities move to Stage 2 and Stage 3?

    • How has that changed over the last 90 days?
  3. Quality check (sample review)
    • Pick 10–15 opportunities at random from Stage 1/2.

    • For each one, ask: Is there a clear problem, a real buyer, and a specific next step?

    • If not, should it really be in the pipeline?
  4. Ageing check (velocity)
    • How many Stage 1/2 opportunities are older than twice your usual early-stage duration?

    • How many are older than your typical full sales cycle?
  5. Source check
    • Which sources or campaigns generate most of your early-stage opportunities?

    • How do those sources convert into Stage 3 and beyond compared to others?

By the end of this quick audit, you’ll have a much clearer sense of whether your top-of-funnel is giving you a fair picture – or quietly undermining your forecast.

 

How this connects to overall pipeline imbalance

Early-stage imbalance rarely stays put. If you allow noisy, low-quality opportunities to stay in the system, several things happen downstream:

  • Managers spend time reviewing and discussing deals that will never close.
  • Forecasts become increasingly detached from reality.
  • Mid- and late-stage metrics are polluted by opportunities that should have been filtered out weeks or months earlier.

That’s why the early-stage red flags in this article link directly back to your overall pipeline health.

If you haven’t already, it’s worth pairing this blog with our pillar piece, How to Spot Pipeline Imbalance Across Stages (Before It Wrecks Your Quarter) – it shows how early-stage distortion affects the entire funnel, and how to use Value, Volume and Velocity to diagnose imbalance at every stage.

 

FAQ summary: early-stage red flags and top-of-funnel health

  1. What does it mean when my top-of-funnel is “lying” to me?
    It means the early stages of your pipeline are giving you an inflated sense of confidence. You see lots of opportunities and impressive value at Stage 1 and Stage 2, but very few of those opportunities are real, qualified deals that progress into the middle of the funnel and ultimately close.
  2. What is the biggest data-driven red flag at early stages?
    The clearest red flag is a very high number of opportunities and large pipeline value in Stage 1/2, combined with weak conversion into Stage 3. If early-stage volume rises while progression stays flat or falls, your top-of-funnel is likely imbalanced.
  3. How can I tell if an early-stage opportunity is actually a lead in disguise?
    Look for three things: a clearly defined customer problem, a real buying role (not just a curious contact) and a specific, agreed next step. If those are missing, you probably have a lead or a marketing contact masquerading as an opportunity.
  4. Why are vague next steps such a problem in early stages?
    Because they hide a lack of real momentum. Generic next steps like “follow up” or “check in” can be pushed forward indefinitely. They keep deals in the pipeline without any evidence that the customer is moving closer to a decision.
  5. How often should I review early-stage ageing?
    At least weekly. Early-stage opportunities that have been open for longer than twice your typical early-stage duration, or longer than your usual full sales cycle, are unlikely to be genuine live deals. Regularly reviewing and closing out those aged opportunities is essential for an honest pipeline.
  6. What should I do if one channel is flooding early stages with low-converting opportunities?
    First, separate out the data by source so you can see the true impact. Then, either adjust the criteria for what counts as an opportunity from that channel, or change how you engage those leads (for example, keep them in nurture programmes until they meet a higher bar). The goal is to stop noisy channels from distorting your top-of-funnel picture.
  7. How does this relate to the wider problem of pipeline imbalance?
    Early-stage distortion is often the first step towards a fully imbalanced pipeline. Noisy top-of-funnel data leads to poor mid-stage metrics and unreliable forecasts. That’s why getting honest about Stage 1 and Stage 2 is a critical foundation for the broader work of balancing your pipeline across all stages.
