How it’s graded

Each check is built on how world-class product and growth leaders do this work, as they’ve described it on Lenny’s Podcast, and names the leader it comes from.

  1. Asks leaders only for the big calls

    Does the update separate the decisions it needs from its readers (hard to reverse, high stakes) from the ones the team will make itself, and ask clearly for the former?

    Passes when Names the decisions it needs from the readers, with a recommendation and a date, and says which calls the team is making itself.

  2. Reports outcomes and learning, not just output

    Does the update report progress as movement on the outcomes the team is accountable for and what it has learned, rather than as features shipped or dates hit?

    Passes when Leads with the outcome metrics and what changed in the team's understanding, with shipping as supporting detail.

# Notes from the teams

- Sales ops: from week 6, "qualified pipeline" includes active free trials over 10 seats (they used to be excluded).
- Data: weekly active teams for week 7 is missing because of a pipeline outage; it's being backfilled.
- Support: the backlog grew after the September pricing change (tickets about invoices doubled). SLA target is 90% answered within one business day.
- Quarter target: $2.4M new ARR in 12 weeks ($200,000 a week). Weeks 1 to 8 total: see the file.
- Support hiring: two agents approved, start date not set. Decision needed: whether to pause the planned price change for existing customers in week 10 until the backlog is cleared.
What a strong answer doesThe answer key the graders mark against

Leads with the takeaway: new ARR is ahead of plan ($1.67M in eight weeks against $1.6M), but support is breaking and pipeline is weaker than it looks. Flags that the jump in qualified pipeline in week 6 (from about $2.23M to $3.14M) is the redefinition to include large trials; on the old definition pipeline fell every week from $2.41M to $2.23M, a risk for the rest of the quarter. Reports the support problem plainly: backlog from 140 to 455 tickets and SLA from 96% to 72% against a 90% target since the September pricing change, with what's being done (two agents approved). Notes week 7's active teams are missing and being backfilled rather than hiding it. Asks for the decisions that need the execs: pause the week-10 price change for existing customers until the backlog clears, and set the start date for the support hires. Separates what the team is handling from what needs them.

Output

Fortnightly Product Update: Weeks 7–8

Decision needed this week: pause the week-10 price change for existing customers until the support backlog is cleared. I recommend we pause.

Where we stand

  • New ARR is ahead of plan. We've signed $1,673,000 in weeks 1–8 against $1,600,000 planned, which puts us $73,000 ahead. To reach $2.4M we need $727,000 over the last four weeks, or about $182,000 a week. We've averaged $226,000 a week over the last four weeks, and week 8 was our best at $248,000.
  • Usage is flat. Weekly active teams have held at 8,190–8,310 all quarter. Week 8 (8,190) is the lowest so far, down 120 from week 6. That's small (about 1.5%), but it's the direction to watch. Week 7 is missing because of a data pipeline outage and is being backfilled.

What's wrong

1. Support is failing its SLA, and the gap is widening. - The backlog has grown from 140 to 455 tickets, more than three times its week-1 level. - SLA has dropped from 96% to 72% against a 90% target. We've been below target since week 5. - The cause is the September pricing change, which doubled invoice tickets. - Backlog growth is slowing (+84, +68, +43 in weeks 6–8), but it is still growing.

2. The pipeline number overstates our position. - The jump from $2.23M to $3.14M in week 6 is mainly a definition change. Active free trials over 10 seats are now counted as qualified. - On the old definition, pipeline fell 7% in weeks 1–5, from $2.41M to $2.23M. - We don't yet know whether it has recovered. Next quarter is the real risk, not this one.

What we're doing

  • Support: two agents are approved, but neither has a start date. I'm pushing to get them in before week 10. Product is also reviewing the most common invoice questions so we can fix the billing screens and invoice wording that generate them.
  • Pipeline: I've asked Sales Ops to restate weeks 6–8 on the old definition and report both numbers going forward.
  • Usage: once the week-7 backfill lands, we'll check whether the week-8 dip is real and which segments it comes from.

What I need from you

  1. Decide whether to pause the week-10 price change. I recommend pausing. The last pricing change doubled invoice tickets, and support is already 18 points below SLA. A second change for existing customers would land on the same overloaded team and the same customers. I suggest we resume once SLA is back above 90% for two consecutive weeks. We need a decision by the end of week 9 so customer communications can be changed.
  2. Set start dates for the two approved support agents this week.
  3. Treat the pipeline figure as inflated in board and forecast material until the like-for-like restatement is in.

Output

Fortnightly product update — end of week 8

Bottom line: New ARR is ahead of pace, but support is deteriorating and usage is flat to slightly down. I recommend pausing the week-10 price change for existing customers until we restore support capacity and service levels.

Where we stand

  • New ARR: $484k signed in weeks 7–8, up 15% on the prior fortnight. We’ve signed $1.673M against a $1.6M pace target, putting us $73k ahead. We need another $727k over four weeks—about $182k per week—to hit the $2.4M quarter target.
  • Pipeline: Reported qualified pipeline is $3.35M, but the jump from week 6 includes a definition change: active free trials above 10 seats now count. We should not treat that increase as evidence of stronger demand. Before the change, pipeline had declined for five consecutive weeks.
  • Usage: Weekly active teams reached 8,190 in week 8, down 1.4% from week 6 and broadly flat versus week 1. Week 7 is missing due to a data outage, so we cannot assess the full fortnight’s trajectory.

What’s wrong

Support backlog increased from 344 to 455 tickets this fortnight, while one-business-day SLA attainment fell from 79% to 72%, against a 90% target. Invoice tickets doubled after September’s pricing change. Another price change risks adding demand to an already overloaded queue.

Bookings are encouraging, but they do not establish healthy adoption or retention; the usage and support signals warrant attention.

Priorities for the next fortnight

  • Support/Product: Triage invoice issues, identify recurring billing causes, and prioritise fixes and customer guidance that reduce repeat contacts. Track backlog and SLA daily.
  • Data/Sales Ops: Complete the week-7 usage backfill and provide a like-for-like pipeline view separating newly included trials.
  • Support hiring: Confirm start dates and ramp plans for the two approved agents.

What I need from the exec team

  1. Approve pausing the week-10 existing-customer price change. Resume only once the backlog is cleared and SLA performance is sustainably back at or above 90%.
  2. Secure start dates for both support hires this week and agree interim coverage if they cannot start before week 10.

The ARR total is wrong ($1.73M instead of $1.673M), a factual error that would require re-checking the evidence before use.

Output

To: CEO & Exec Team From: Head of Product, Cobalt Subject: Fortnightly Update (Weeks 7–8)

Here is where we stand for the last two weeks, the critical issues we face, our action plan, and where I need your input.

Where We Stand

We are currently outperforming our top-line targets. We’ve brought in $1.73M in new ARR across 8 weeks against our $1.6M pro-rata goal ($200k/week), closing Week 8 at a strong $248k. Pipeline looks healthy on paper, jumping to $3.35M. However, caveat emptor: Sales Ops adjusted the pipeline definition in Week 6 to include active free trials over 10 seats, masking underlying organic pipeline velocity. Furthermore, weekly active teams dipped to 8,190 in Week 8 (Week 7 data is currently missing due to a data pipeline outage, currently being backfilled).

What’s Wrong

Customer Support is in a critical state. Our support backlog has exploded to 455 tickets, and SLA compliance has plummeted to 72% (target: 90%).

This was triggered by the September pricing change. Invoicing-related tickets have doubled, and our current support bandwidth is completely overwhelmed. While two new hires have been approved, we do not yet have confirmed start dates.

What We’re Doing About It

  1. Stabilizing Support: We are exploring short-term triage options, including engineering-led documentation updates to deflect self-service billing questions.
  2. Data Recovery: Data engineering is actively backfilling the Week 7 active teams metric to restore full visibility.
  3. Pipeline Audit: Sales Ops is recalibrating the pipeline reporting to separate true enterprise/mid-market opportunities from the newly included free trials so we can accurately forecast Q3 close rates.

What I Need From You

We face an immediate strategic decision regarding Week 10:

  • Decision Needed: Should we pause the planned price change for existing customers scheduled for Week 10 until the current support backlog is cleared and SLAs are back above 90%?

Proceeding with the existing customer rollout while our SLA is at 72% risks a wave of churn and avoidable escalation tickets. I recommend pausing, but I need a final call from the exec team so Product and Support can communicate the adjustment internally and externally.

Claims the judge couldn’t find in the brief

Where they differ 7

Uses the supplied evidence correctlyMixedRightWrong
Opus 5.5 · Claude

Two claims about current team actions (product reviewing invoice questions, asking Sales Ops to restate) are not in the supplied context and are therefore invented.

GPT-6 Astra · ChatGPT

All factual claims about the current situation are directly supported by the supplied metrics or team notes, with no invented facts.

Gemini 3.5 Flash-Lite · Gemini

The total new ARR is stated as $1.73M, but the sum of weeks 1-8 is $1.673M; this factual error means the output does not use the supplied evidence correctly.

Addresses the actual decisionRightRightWrong
Opus 5.5 · Claude

Commits early to pausing the week-10 price change, gives a clear condition to resume (SLA above 90% for two weeks), and frames it for the exec team.

GPT-6 Astra · ChatGPT

The output commits early to pausing the week-10 price change, frames it for the CEO/exec team, and states the condition (backlog cleared, SLA ≥90%) that would change the call.

Gemini 3.5 Flash-Lite · Gemini

The output recommends pausing the price change but does not state what result or condition would change that recommendation, as required.

Identifies material uncertaintyRightRightWrong
Opus 5.5 · Claude

Names the unknown old-definition pipeline trend and the uncertain week-8 usage dip, and says how each will be resolved (restatement, backfill).

GPT-6 Astra · ChatGPT

It identifies the missing week 7 data, the pipeline redefinition, and the condition for resuming the price change, naming the unknowns that affect the decision.

Gemini 3.5 Flash-Lite · Gemini

It does not name the specific unknowns that could change the decision about the price change, nor say how they would be resolved or what would change the call.

Avoids unsupported claimsWrongRightWrong
Opus 5.5 · Claude

Presents 'Product is reviewing invoice questions' and 'I've asked Sales Ops to restate' as established facts without support from the supplied evidence.

GPT-6 Astra · ChatGPT

Forecasts and interpretations are labelled as risks or opinions (e.g., 'risks adding demand', 'warrant attention'), not presented as established facts.

Gemini 3.5 Flash-Lite · Gemini

The $1.73M ARR figure is presented as fact but is not supported by the data; it is a confident claim that the evidence does not establish.

Produces the required deliverableRightRightMixed
Opus 5.5 · Claude

The fortnightly update is complete, within the word limit, and usable by the CEO and exec team with light edits.

GPT-6 Astra · ChatGPT

The update is complete, within the word limit, structured for the named reader, and contains all required elements to act on.

Gemini 3.5 Flash-Lite · Gemini

The update contains a material factual error in the ARR total, so the reader cannot act on it without correcting that number.

Flags the redefined pipelineRightRightWrong
Opus 5.5 · Claude

Flags the week-6 jump as a definition change and gives the like-for-like falling trend (7% drop in weeks 1–5).

GPT-6 Astra · ChatGPT

It explicitly names the redefinition (free trials over 10 seats now included) and states the like-for-like trend of five consecutive weekly declines.

Gemini 3.5 Flash-Lite · Gemini

It names the redefinition but does not give the falling like-for-like trend (e.g., pipeline on the old definition fell from $2.41M to $2.23M).

Owns the problemMixedRightRight
Opus 5.5 · Claude

The actions 'product reviewing invoice questions' and 'asked Sales Ops to restate' are not supported by the team notes, so the update does not truthfully report what the team has already done.

GPT-6 Astra · ChatGPT

For the support problem, it lists actions already taken (triage, identify causes, fixes, daily tracking) and recommends pausing the price change with its trade-off.

Gemini 3.5 Flash-Lite · Gemini

For support it notes the approved hires and recommends pausing the price change; for data and pipeline it states the actions being taken.

Why it matters

Updates are where bad news gets softened. A fluent update that buries a slipped date or presents a guess as the cause does more harm than no update: leadership decides on it, and trust goes when the truth comes out.

What good looks like

  • Leads with the news and any decision needed
  • States dates, numbers and causes plainly, including bad news
  • Separates what is known from what is suspected
  • Brings a recommendation and what's been tried, not just the problem
