PRISM Write to Erin
Fractional HR practice · by referral

Nobody plans to become the people person.

At PRISM that part of the job belongs to Erin H. Robertson — for founders of growing startups and partners at law firms who never planned to lead, hire or manage.

  • 01 Retained, not project-billed
  • 02 One senior person, no juniors

02 — Why you are here

Someone you trust sent you this link.

That is how PRISM works. No sequence of emails begins now. No deck follows. This page exists to confirm, in plain words, what the person who sent it already told you — so the first conversation can start further along than it usually does.

Read what is here. If the shape of it matches the thing keeping you up, write. Thirty minutes, no obligation, and a straight answer about whether this is the right moment to bring someone in at all.

03 — Who it is for

Two rooms, one unglamorous problem.

The work has outgrown the founder's inbox and the managing partner's memory, but it has not yet earned a full-time department. That gap is where things quietly break.

A — Founders

You are past thirty people and improvising.

Hiring accelerated, titles multiplied, and the operating manual is still a shared doc nobody has opened since the last raise.

  • 01 Compensation bands your board will accept
  • 02 Offers, onboarding and probation that hold up
  • 03 First-time managers who do not learn on your team
  • 04 Policy that satisfies diligence without theatre
B — Law firm partners

Your people questions outrank your billable hours.

Associate retention, lateral integration and the difficult conversation all arrive on your desk because there is nowhere else for them to go.

  • 01 Associate progression and partner-track clarity
  • 02 Lateral onboarding that survives year one
  • 03 Sensitive matters handled with privilege in mind
  • 04 Compensation conversations, professionally staged
04 — The practice

Six facets. One people function.

01 / 06
01 — Foundations

Structure & compliance

Placeholder. Contracts, handbooks, classifications and the documentation that makes diligence uneventful.

02 — Intake

Hiring & onboarding

Placeholder. Scorecards, interview loops and a first ninety days that actually produces a productive hire.

03 — Reward

Compensation design

Placeholder. Bands, equity philosophy and a review cadence that removes the annual negotiation ambush.

04 — Growth

Performance & progression

Placeholder. Levelling, review cycles and promotion criteria people can read without having them explained.

05 — Risk

Employee relations

Placeholder. Grievances, investigations and exits handled calmly, documented properly, closed completely.

06 — Continuity

Culture & retention

Placeholder. Engagement signals, manager capability and the quiet work of keeping the people you fought to hire.

05 — How it goes

Read the room. Build the thing. Stay.

01

DiagnosticTwo weeks

Placeholder. Interviews across levels, a document review, and a candid written assessment of where the exposure actually sits — not where it is assumed to sit.

02

BlueprintSix to ten weeks

Placeholder. A sequenced plan with owners and dates, ordered by risk and by what unblocks the next stage of growth. Every phase ends with something in operation.

03

EmbeddedOngoing, retained

Placeholder. Days per month in your tools and your meetings, and availability for the conversation you would rather not have alone.

06 — The shape of it

Small on purpose. Placeholder figures.

Placeholder biography. Fifteen years building people functions inside venture-backed companies and professional services firms, most of it spent in the room where the difficult decision was being made rather than in the deck describing it afterwards.

PRISM is deliberately small. A handful of retained clients at a time, every hour delivered by the person you met on the first call. No account managers, no template libraries, no work handed down.

08 — Before you write

The five that always come first.

What does a fractional engagement actually look like?
Placeholder answer. A fixed number of days each month, agreed in advance and spent on the sequenced priorities from the blueprint — plus availability between sessions for the things that cannot wait until the next one.
How is this different from hiring an HR manager?
Placeholder answer describing the seniority difference, the breadth of exposure across many organisations, and the fact that the engagement is designed to eventually hand over to the in-house hire you will then be ready to make.
Do law firms get a different version of this?
Placeholder answer. Partnership structures, lockstep and merit systems, and privilege considerations change the shape of the work — though the six facets underneath stay the same.
What does it cost?
Placeholder answer. A monthly retainer scaled to the days committed, quoted after the intro call, with the diagnostic priced separately and credited against the first three months.
Can PRISM help with something urgent this week?
Placeholder answer. Short standalone engagements are accepted for investigations, restructures and sensitive exits, subject to availability — say so in the first line and it gets read first.
09 — Next step

Start with a conversation.

Placeholder closing line. If it is not the right moment, that will be said plainly on the call — PRISM would rather be the second conversation you have this year than the wrong first one.
