Most developer tools companies can report monthly signups and MRR, but almost nothing between them – where users drop off before making their first API call, which onboarding step prevents activation, or whether a marketing growth idea ever ships because engineering has no capacity dedicated to it. We build the tracking, event pipelines, and in-product growth infrastructure needed to answer those questions, then connect the loops that act on the findings.
The Challenge
No engineer owns activation tracking, leaving the funnel invisible
Marketing wants to know where signups drop off before first value, but that data lives inside application code nobody on the growth side can touch. Product engineers are focused on the roadmap, not event tracking, so activation questions get answered with guesses instead of numbers. The result is a team debating whether onboarding or docs are the problem with no way to settle it, while signups keep leaking at a step nobody has actually measured.
Growth experiments don't ship because the engineering backlog always takes priority
Marketing proposes an A/B test on the signup flow or a tweak to the free-tier limit, and it sits in the backlog behind feature work indefinitely because there's no dedicated capacity and no infrastructure to ship a variant safely. Every experiment becomes a full engineering request instead of a config change, so the team runs two or three tests a year instead of two or three a month. Competitors iterating faster on their funnel compound that gap every quarter this goes unaddressed.
The self-serve signup funnel is leaking, and nobody tracks the drop-off
A developer starts a free trial, hits a confusing setup step, and leaves – and unless someone built event tracking at that exact step, the company only sees the aggregate conversion number moving down with no idea why. Support tickets and sales calls surface anecdotes, but anecdotes don't tell you if the drop is at API key generation, first integration, or billing setup. Fixing the wrong step wastes an engineering sprint while the actual leak keeps costing signups.
API and SDK usage events go untracked, making activation a guess
For a developer tools company, the real activation moment is usually a specific API call, a completed SDK install, or a first successful request – not a marketing-defined milestone like 'logged in.' Without event tracking on those specific product actions, the team can't build a real activation metric, can't segment users by depth of usage, and can't trigger anything – an email, an in-app nudge, a sales alert – off genuine product behavior. Growth strategy ends up built on login counts instead of the signal that actually predicts retention.
How We Can Help
We begin by auditing what's truly instrumented today against what the team thinks is instrumented – following the real signup-to-activation journey through the product, verifying which events fire, identifying what's missing, and finding inconsistencies in the event schema across web, API, and SDK. Most teams are surprised to learn how much of their reported funnel is estimated instead of measured.
Using the audit, we create an activation event map tailored to the product: the precise API calls, SDK milestones, or in-product behaviors that predict whether a user will stick around, aligned with product and engineering so it represents actual usage rather than a marketing assumption. This map becomes the foundation for every growth decision that comes next.
For execution, we build the tracking and event pipeline – instrumenting signup, onboarding steps, and key API/SDK actions, then sending the data somewhere growth and product teams can query without submitting an engineering ticket. When useful, we implement lightweight feature-flag or configuration infrastructure so marketing and growth can test funnel changes – a reordered onboarding flow, an adjusted free-tier limit – without requiring a complete engineering cycle each time.
We also create in-product growth loops when supported by the data: usage-triggered emails for developers who stall before an important activation event, in-app prompts connected to genuine product milestones, and referral or invite mechanisms tied to actual usage instead of generic signup totals.
For measurement, we build dashboards showing signup-to-activation conversion at each step, segmented by acquisition channel and account type. That lets the team identify exactly where the funnel leaks and determine whether a shipped change moved the number – not merely whether it launched.
Unlike a marketing agency that delivers a strategy deck, we provide working infrastructure – event tracking, dashboards, and experimentation scaffolding that your team continues operating after the engagement. We deliver code with handoff documentation, not slides.
What we deliver
- Activation event map covering signup, onboarding, and core API/SDK milestones
- Event tracking and pipeline instrumentation across web, API, and SDK surfaces
- Lightweight feature-flag or config infrastructure for shipping funnel experiments without a full engineering cycle
- In-product growth loops – usage-triggered emails, in-app prompts, referral mechanics tied to real activation signals
- Funnel dashboards showing signup-to-activation conversion by step, channel, and account type
If you cannot identify the exact API call or SDK event that distinguishes an activated user from a signup who never returned, you don't have an activation metric – you have a login count labeled as one.
Our Methodology
Our 90-day growth engineering sprint follows three phases, with instrumentation coming before optimization – you can't repair a funnel step that hasn't been measured. Days 1-30 cover the audit and event map: we follow the real signup-to-activation journey in the product, document what's actually tracked versus assumed, and align on the exact API/SDK events that represent genuine activation for this product, rather than a generic 'user logged in' proxy.
Days 31-60 focus on building. We add instrumentation for missing events, create the pipeline that makes the data queryable without an engineering ticket, and establish lightweight experimentation infrastructure – feature flags or straightforward config toggles – so the team can launch a funnel variant within days rather than wait for the next sprint. If existing data reveals an obvious leak, we build the first in-product loop to address it during this phase instead of holding it for phase three.
Days 61-90 move into measurement and handoff. We build the funnel dashboards, confirm that their underlying events reflect what really occurred in the product, and document the tracking schema and pipeline so your engineering team can expand it without us. Unlike a growth marketing retainer that stops with the contract, the instrumentation and infrastructure remain live and internally owned when the sprint ends.
Our Working Process
The first 30 days focus on diagnosis and typically place one growth engineer directly in your codebase and analytics stack, rather than working on a deck. We require read access to your event pipeline (Segment, Amplitude, PostHog, or whatever you use), along with visibility into the actual signup and onboarding code, to create an accurate view of what's tracked.
Days 31-60 are dedicated to building, when our involvement in your codebase is greatest – shipping event instrumentation, creating pipelines, and developing the first growth loops. We work within your current repo and deployment process rather than using a separate sandbox, with changes passing through your standard code review so your team remains up to date on every addition.
Throughout the engagement, the cadence includes a weekly working session with the person responsible for product/growth on your side, plus asynchronous updates as instrumentation goes live. This isn't a black-box process – your team watches each event get added and every dashboard take shape, and can reprioritize if a more urgent need emerges.
Most engagements last 3-6 months. The initial 90 days establish the core instrumentation and first loops; teams continuing beyond that generally spend the additional time creating a complete experimentation program on the infrastructure now established, rather than launching another audit from the beginning.
- Activation and funnel visibility where none existed before
- Faster time from growth idea to shipped experiment
- Signup-to-first-API-call time reduction
- In-product loops running on real usage signals instead of login counts
- Engineering-owned instrumentation that outlives the engagement

Frequently asked questions
What is the cost of a growth engineering engagement?
Most growth engineering engagements for developer tools companies cost $10K-$25K per month, based on how much instrumentation our engineer handles directly in your codebase versus pairing with a member of your team. That's generally less than hiring one senior growth engineer, without a multi-month recruitment process, and the infrastructure remains yours after the engagement.
How soon will we see results from growth engineering?
Instrumentation and the initial funnel dashboards generally go live within 30-45 days, letting you see the leak for the first time before any fixes are even made. Measurable conversion lift from launched experiments usually begins to appear by day 60-90, because the first changes require real traffic for validation against the new tracking.
How does your team collaborate with our current engineering team?
We operate directly in your repo through your established code review process, rather than in a disposable separate sandbox. Your engineering lead reviews each instrumentation change before merge, and when the engagement concludes, your team owns the pipeline and can extend it without our help.
How does this differ from a conventional growth marketing agency?
A growth marketing agency usually delivers campaign strategy and creative rather than code. Our work is engineering – event tracking, pipeline infrastructure, feature-flag scaffolding, and in-product loops – implemented as operational systems within your codebase, not presented as a strategy document.
How do you evaluate ROI for a growth engineering engagement?
We measure signup-to-activation conversion at each funnel step before and after instrumentation, along with the change in the number of funnel experiments that ship monthly once the flag infrastructure exists. When we build a specific loop – such as a stalled-activation email or an in-app nudge – we compare that loop's conversion against a holdout, making the lift attributable rather than assumed.
What type of developer tools company is the best fit?
The right fit is a Series A/B/Growth stage developer tools company with roughly $5M-$100M ARR, a self-serve or product-led signup motion, and sufficient signup volume for funnel data to become statistically meaningful in weeks instead of months. It's not a good fit for purely enterprise-sales-led companies without a self-serve funnel, because there is no activation journey to instrument in the first place.
