What are the key things to consider post-launch? What standard metrics are important to track to measure success and what teams (and at what cadence) are important to connect with post-launch?

Can really vary product to product — but I'd separately track product metrics you're able to drive and marketing channel performance. If you have the tech stack for it, ideally you can measure how much product adoption was driven your marketing efforts to keep yourself accountability and prove incrementality. For your marketing channels, you'll want to maintain a rigorous internal dashboard of engagement rates, open rates, performance metrics, etc. for all your launches, so you can develop accurate benchmarks.

I've seen this vary from top-of-funnel metrics down to MRR depending on the goal of the product. Aspects that I believe impact the KPI you ultimately choose are:

• What does this product mean for your company?
• Is it awareness of your company in the market? 
• Is immediate revenue important or can it be pushed down the road?
• How well do you understand user pathways from signup to product usage?
• How well do you understand your funnel?
• Do you have historic data to base assumptions on or is this a green-field launch?
• Are you confident in the amount of traffic you'll be driving from specific channels?
• Do you have a captive audience anywhere that you can take advantage of?

You'll choose very different KPIs depending on how you answer the above questions. For the most recent launch we focued on in-product usage (MAU, engagement rate) instead of revenue. For bootstrapped, single-product companies, revenue was my KPI. For startups with money it might be signups to show growth. Understanding what marketing should do for your company will help to create impactful KPIs that don't focus on vanity metrics.

Landing is everything, but can oddly become an afterthought in the eyes of an organization. It just doesn't have the same sizzle as a launch, right? But landing is where you get the business impact and that is, after all, our goal.

"Standard" metrics are a bit challenging to identify because they really are dependent on your business - what was the goal of the launch, what can be measured, and what larger business objective does this launch ladder into?

Here are some standard metrics I've used, and why they matter:

• Usage: how much is this product being used?

• Revenue: how much value are we driving for the business?

• Adoption: is the product resonating with a wide audience or just a few?

• Sales close rate: is there a pretty clear product-market fit?

• Sales cycle time: is the product addressing an urgent need, or is it a nice-to-have?

• Support ticket volume and trends: is there something that is making it hard for customers to adopt the product?

Against each of these, I look at the trend lines over time and try to understand if each marketing intervention drives incremental improvements in the metrics. I often look at a month, 3 months, 6 months, 1 year out but this is going to change a lot depending on how long your products typically take to adopt.

Your key stakeholders start with Product and Sales but could be as wide as your leadership team or any partners you work with to sell.
