How Series A startups should consolidate their growth stack.
Every Series A company we talk to has 5–7 overlapping growth tools and can't tell you what each one does distinctly. Here's the 90-day consolidation plan that doesn't break testing velocity — and usually improves it.
- ▸Stack consolidation is a forcing function, not a cost-cutting exercise — the biggest wins are operational.
- ▸90 days is the right horizon. Faster breaks things; slower loses momentum.
- ▸The sequence matters: audit first, migrate second, optimize third. Teams that skip the audit fail.
- ▸Retention velocity usually improves during consolidation, not after. Fewer dashboards = faster decisions.
Audit before you migrate.
The first 30 days are for understanding what you have, not changing it. Every tool gets documented: cost, job, user. Most teams discover 30–50% of their stack is doing overlapping or zero work. Run the stack consolidation audit — it pays for itself whether you consolidate or not.
- ▸Pull every growth-related subscription.
- ▸Map each tool to a unique job.
- ▸Tag: KEEP, CONSOLIDATE, CANCEL.
- ▸Document the decision logic so your successor (or future you) doesn't re-do it.
Migrate the bottom half first.
Counter-intuitive: migrate the tools you care about least first. This teaches your team the consolidation muscle on low-stakes tools before you touch the critical ones. Migrating Optimizely to a new platform before your team has ever done a migration is how consolidation projects fail.
- ▸Start with lowest-stakes tools (Slack bots, Zapier workflows).
- ▸Build the migration playbook on tools that can't break anything important.
- ▸Migrate the important tools (testing platform, CI) only after you've done 2–3 low-stakes migrations.
Optimize the consolidated stack.
The last 30 days are where most consolidation projects quietly fail. The tools are migrated, but the workflows still look like the old stack. This is where you rewrite your weekly cadence to match the new tooling — and where the velocity gains actually show up.
- ▸Rewrite your weekly test-council meeting to match the new tooling.
- ▸Replace the Friday briefing with the new platform's briefing.
- ▸Retire the old integrations and Zapier workflows.
- ▸Run a 30-day retro. Document what worked, what didn't, what to change.
Why most consolidations fail.
Three failure modes account for 80% of consolidation projects that stall: no executive sponsor, no migration owner, and attempting to migrate everything at once. Avoid all three and consolidation becomes a 90-day project instead of a 18-month saga.
- ▸Need an executive sponsor (VP or CRO) who owns the budget reassignment.
- ▸Need a single migration owner — not a committee.
- ▸Never migrate everything at once. Sequence matters.
