The mirror sites (1:1 microsites) checklist: 25 things to have in place for PE-backed portfolio companies
A single-page checklist to audit whether your mirror sites (1:1 microsites) setup is production-grade or a science project. Written for operating partners and portfolio CEOs inside private equity.
This edition is written for operating partners and portfolio CEOs inside private equity. In PE-backed portfolio companies, PE-backed operators run on 90-day cycles and reward operating rigor over storytelling, so the way you install mirror sites (1:1 microsites) has to reflect that reality from day one.
Use this as a pre-flight before you commit spend to mirror sites (1:1 microsites). Each item takes minutes to check and hours to fix later.
List, trigger, message. If any of the three is generic, stop and fix the generic one before you touch the other two. Generic list plus sharp message beats sharp list plus generic message, but only for a week.
Owner, cadence, metric. One named human owns the model. The cadence is written down. Meeting rate from account-specific URLs is the number in every review.
The binding constraint we see in PE-backed portfolio companies is almost always predictable execution against a hold-period thesis. Mirror sites (1:1 microsites) is only useful in this vertical when it is pointed at that constraint — not at a generic growth number borrowed from another category.
Data, tooling, workflow. Data flows to one place. Tooling is minimal. Workflow survives the owner going on holiday.
Quality gate, kill criteria, learning loop. Nothing ships without a human eyeballing it. Anything below the bar dies inside a week. What you learn feeds Monday.
Ethics, brand, deliverability. You will not do anything on this list you would not want on the front page. Brand is protected. Sending infrastructure is separated from the primary domain.
Governance, budget, escalation path. Someone above the owner cares. Budget is finite and defended. Bad news travels up in hours, not weeks.
If more than three of these are missing, mirror sites (1:1 microsites) is not going to produce a durable meeting rate from account-specific URLs. Fix them in order and re-run the checklist in a month.
Concretely for PE-backed portfolio companies: the portfolio companies that install this hit the next value-creation milestone on schedule. That is the reason it is worth installing mirror sites (1:1 microsites) properly rather than half-heartedly across three vendors.
