ACTIVATION, FOR SEED → SERIES A B2B SAAS

Know exactly which 10 events predict whether your users stay.

Sennet is a two-week sprint that gives you the real activation metric, a PQL model, and an event taxonomy that won’t rot — for a fixed $5,000. Founder-run. No SDRs. No agency theater.

sennet  /ˈsɛnɪt/ n. — an Elizabethan stage cue: a trumpet signal marking the right entrance at the right moment.

01 — THE PROBLEM

You wired up the events. So why is the data useless when you need it most?

Capturing everything feels like progress. Then you go to answer one question — “is this cohort actually activating?” — and discover the taxonomy is inconsistent, “activation” was never really defined, and the events you needed were never the ones you tracked.

01

The taxonomy rots in three months

Three engineers, three naming conventions. btnClick, button_clicked, CTA Pressed — all the same action. No one owns it, so it drifts until no chart can be trusted.

02

“Activation” is defined by gut feel

Someone picked a metric in a meeting because it sounded right. No one checked whether it actually correlates with users who stick around. You’re optimizing a number that doesn’t predict retention.

03

It breaks exactly when you’re raising

The board wants activation and retention curves. The data can’t support the story — right when scaling or fundraising makes it matter most. The fix is a scramble, not a system.

The hard part was never wiring up the events. It’s knowing which events predict whether someone stays.

02 — WHAT YOU ACTUALLY GET

The Activation Instrumentation Sprint

Fixed scope · fixed price · ~1–2 weeks

A real activation metric

Defined empirically — the behavior that actually separates users who stay from users who churn. Not a guess.

A PQL scoring model

A weighted, product-qualified-lead score sales and lifecycle can trust.

# illustrative — yours is fit to your data
pql = 0.45·first_query_run
    + 0.30·invited_teammate
    + 0.25·return_d2
    − 0.20·hit_error_onboarding

Funnel & retention dashboards

PostHog-flagship (or Mixpanel / Amplitude / Segment) — built so they keep working after I’m gone.

Data-quality guardrails

A naming convention, a tracking plan, and validation so the taxonomy doesn’t rot the moment the next feature ships.

A prioritized leak roadmap

Your biggest drop-offs, quantified — ranked by how much retained revenue each one is costing you.

An event taxonomy that holds

10–15 events worth instrumenting — chosen because they predict whether someone stays, not because they were easy to capture.

03 — HOW IT’S DIFFERENT

This is judgment, not setup.

Plenty of people can install an SDK. The value isn’t the wiring — it’s deciding what’s worth measuring and why. Here’s the line.

vs. DIY in-house

Your founder can wire the events. What the team is missing isn’t engineering — it’s the judgment about which signals predict retention, and the time to do it right while shipping the product.

vs. generic CRO

CRO moves the button and argues about copy. Sennet doesn’t hand you UI opinions — it tells you what to measure so you know which button even matters.

vs. a $150 setup gig

A cheap Upwork “set up my events” gig gives you an SDK install. It can’t tell you what’s worth tracking. (PostHog itself prices hands-on help from a $5k minimum — the judgment is the cost, not the code.)

04 — WHO’S DOING THE WORK

I’m Dawid Nawrocki. Ten years of building activation and PLG systems for US B2B SaaS.

Senior growth engineer. I’ve shipped activation experiments, attribution stacks, and event pipelines at Appsmith, Hygraph, Pilot, Stenn, and Ziflow — across PLG, lifecycle, and GTM engineering. I kept watching the same thing happen: teams ship more events, dashboards multiply, but the question “is this user actually activating?” still gets answered with a shrug. Sennet exists because the fix isn’t more tooling — it’s judgment about what to measure.

WHAT THAT LOOKED LIKE IN PRACTICE

+18%
signup conversion at Appsmith — systematic onboarding A/B tests, +$150K to annual pipeline.
15+
channels of CAC tracked accurately — designed Appsmith’s attribution stack Segment → Mixpanel → Salesforce.
+19%
average lift across 15+ funnel experiments at Pilot, built on the Segment → BigQuery pipeline I shipped across 8 tools.
+31%
demo requests (bounce −22%) from rebuilding Pilot’s homepage from scratch.
200+
growth teams use GrowthOS, my open-source PLG toolkit — activation specs, tracking plans, KPI dashboards.

When you hire Sennet, that’s who does the work — start to finish. The judgment you’re paying for is the judgment in the room.

06 — PRICING

Transparent, on purpose.

Most agencies hide the number until they’ve read your funding announcement. Here it is. Fixed scope, fixed price, no surprises.

START HERE

Activation Instrumentation Sprint

from $5,000

Fixed scope · ~1–2 weeks · one project.

  • Activation metric, defined empirically
  • Event taxonomy (10–15 events) + tracking plan
  • PQL scoring model
  • Funnel & retention dashboards
  • Data-quality guardrails
  • Prioritized leak roadmap, quantified
Start with a free teardown

Founding-client rate available for the first few reference projects.

WHAT COMES NEXT

Lifecycle Orchestration

from $20,000 foundation

+ retainer from $3,500/mo

Once the events are trustworthy, turn them into behavior-triggered messaging — built in Customer.io, on top of the taxonomy from your Sprint:

  • · Onboarding & activation sequences
  • · Trial-conversion nudges, tied to PQL score
  • · Churn-save & win-back flows
  • · Ongoing iteration against the funnel

The natural next step — but only after the instrumentation is solid. No point automating messages off events you can’t trust.

07 — HOW IT WORKS

Two calls. The rest is async.

You’re building a product, not attending standups. The process is low-overhead by design — and you work directly with the person doing the work, not an account manager.

STEP 01

Form intake

You send the product URL and your activation question. I review your funnel before we ever talk.

STEP 02

One kickoff call

30–45 minutes to align on scope, access, and what “activated” should mean for your product.

STEP 03

Async delivery

Work happens against clear milestones, shared as it lands. No meetings to justify progress.

STEP 04

One readout call

A walkthrough of the metric, model, dashboards, and the ranked leak roadmap. Then it’s yours.

Response time: within 1 business day. Always.

08 — WHO IT’S FOR

Is Sennet the right fit for your team?

If the operator described above sounds like the kind of person you’d want in the room — here’s how to tell whether Sennet is right for you. Better to know now than three weeks in.

A FIT IF YOU’RE…

  • Seed–Series A B2B SaaS
  • Freemium or free-trial motion
  • Dev tools / API products especially
  • Have signups, but activation is a mystery
  • Want a system, not a dashboard dump

NOT A FIT IF YOU…

  • Have no real PLG motion yet
  • Are pre-product / pre-signups
  • Want UI/CRO opinions on your buttons
  • Just need a cheap SDK install
  • Want a managed team, not the operator

09 — FREE TEARDOWN

Send your funnel. Get the analysis.

I’ll record a short teardown of your activation funnel — where users drop, what you’re probably mis-measuring, and the one signal worth chasing first. No pitch deck, no call required to get it.

  • Reply within 1 business day
  • You talk to the operator, not a funnel of SDRs
  • No spam, ever — your URL is all I need

The teardown is built from observing your real signup→activation flow.

No spam. One human reads every submission.
