Case study at a glance
1
What was the user problem?
Recruiters used 4–6 disconnected tools to reach the same candidate — email, WhatsApp, SMS, LinkedIn InMail, VoIP — with no shared history. Every outreach was a cold start. Response rates were low and candidate experience was broken.
2
What was your role?
Lead Product Manager at Workllama, owning this 0→1 product end-to-end — discovery, spec, engineering alignment, CS partnership, beta design, and GA launch.
3
What were the key constraints?
10-week ship window. Had to cut 40% of V1 scope to hit it. Built on Twilio + SendGrid rather than native email — adding integration complexity. No existing messaging infrastructure to build on.
4
What decisions did you make?
Bundled as core feature (not add-on) to maximise adoption. Cut bulk messaging and AI scheduling from V1. Chose CS-led onboarding over training decks. Built Chrome plugin so recruiters could reach candidates from LinkedIn without switching apps.
5
What changed after launch?
Candidate engagement +40%. Mobile adoption +35%. 70% of target users activated within 3 weeks of GA — above the 60% 30-day target. Became the platform's most-used daily feature. Cited in the TIARA Contractor Solution of the Year nomination.
01 — The Problem

Recruiters were drowning in tool chaos

When I joined Workllama, recruiters were operating across a fragmented stack — email clients, SMS apps, LinkedIn InMail, WhatsApp, and VoIP tools — to reach the same candidate. There was no unified thread, no context, and no visibility. Every outreach was a cold start.

A recruiter reaching out to a candidate for the third time had no way of knowing what was said in the first two. Conversations were scattered across 4–6 tools. Response rates were low. Candidate experience was disjointed. And recruiters were spending 30–40% of their time just managing communication logistics rather than building relationships.

This wasn't a recruiter problem — it was a platform gap. Workllama had strong ATS capabilities but zero owned communication layer. The moment a recruiter wanted to reach a candidate, they left the platform entirely.

02 — Discovery & Framing

Understanding the real job to be done

Before writing a single spec, I spent three weeks in discovery — sitting with recruiters, running structured interviews, and auditing real workflows. I also worked closely with Customer Success to understand churn signals tied to communication frustration.

1
Recruiter shadowing sessions
8 recruiters across 3 enterprise customers
Watched live workflows, timed context-switching, logged every tool touchpoint. Found that the average recruiter switched apps 11 times per outreach sequence.
2
Customer Success interviews
Churn analysis + NPS comment mining
Communication friction appeared in 6 of the last 9 churned accounts. CS flagged it as the #2 reason customers went back to legacy ATS tools that had basic messaging built in.
3
Competitive audit
Bullhorn, Greenhouse, Lever, iSmartRecruit
Most competitors had basic email integration. None had a unified multi-channel inbox with candidate context and conversation history. This was a differentiation opportunity, not just a parity gap.
4
Problem framing with engineering lead
Technical feasibility + build vs integrate decision
Evaluated Twilio, SendGrid, and custom WebSocket approaches. Decided on a hybrid: Twilio for SMS/voice, native email integration, and a custom real-time chat layer — giving us full control over the UX and data.

"We leave the platform the moment we need to talk to someone. That's where deals die."

03 — The Solution

A unified communication layer built for recruiter speed

The Communication Hub was designed around one north star: a recruiter should be able to reach any candidate, on any channel, with full context — without ever leaving Workllama. Mobile-first by design, because 60% of recruiter outreach happened outside office hours.

📬

Unified inbox

SMS, email, and in-app messages consolidated into a single threaded view per candidate. No more context switching or lost history.

📱

Mobile-first design

Full communication capability on iOS and Android. Recruiters could respond to candidates during commutes, interviews, and client visits.

🤖

Personalised templates

AI-assisted message templates that pulled candidate name, role, and stage automatically — reducing manual composition time by 60%.

📊

Engagement analytics

Open rates, response rates, and channel performance per recruiter. Gave team leads visibility into outreach effectiveness for the first time.

Chrome plugin

Browser extension enabling recruiters to initiate outreach directly from LinkedIn or job boards — capturing leads into the Hub without copy-pasting.

🔗

Integration layer

Connected to Twilio (SMS/voice), SendGrid (email), and native in-app — single API abstraction so the platform, not the recruiter, handles channel routing.

04 — Execution & Stakeholder Alignment

Shipping a 0→1 product across three stakeholder groups

The three hardest alignment challenges were engineering (build scope and technical debt tradeoffs), Customer Success (managing beta expectations with enterprise clients), and clients themselves (change management for a workflow shift).

1
Engineering alignment
Scoping the MVP without over-building
Ran a joint prioritisation workshop using a value-vs-complexity matrix. Cut 40% of initially scoped features from V1 — including bulk messaging and AI scheduling — to ship the core unified inbox in 10 weeks. Created a clear V2 roadmap so engineering understood the vision without needing everything in V1.
2
Customer Success partnership
Designing the beta program
Worked with CS to select 3 design partners — one enterprise, one mid-market, one staffing agency. Ran biweekly feedback sessions, created a shared Notion tracker for issues, and committed to a 48-hour response SLA on all beta feedback. This built trust and produced 60+ actionable insights before GA.
3
Client change management
Getting recruiters to actually adopt it
Co-created onboarding materials with CS — video walkthroughs, a quick-start guide, and an in-app tooltip flow. Ran live onboarding sessions for the first 5 accounts. Adoption hit 70% of target users within 3 weeks of GA — above our 60% 30-day target.
05 — Results

Measurable impact across engagement, retention & revenue

Six months post-GA, Communication Hub was the most-used daily active feature on the platform — ahead of job posting and candidate search. It became a key differentiator in sales conversations and directly contributed to reduced churn.

Communication Hub was subsequently cited in Workllama's TIARA Talent Award nomination for Contractor Solution of the Year and featured as a key differentiator in the Ardent Partners Key Provider 2022 recognition.

On measurement: Engagement rate and adoption figures were tracked via Workllama's internal analytics platform across a 6-month post-GA window. The 70% activation figure reflects users who completed at least one outreach action via the Hub. "User satisfaction +50%" reflects an internal CSAT survey run across 3 enterprise accounts, not a platform-wide NPS — the sample size was meaningful but not exhaustive. Beta insights count (60+) includes both structured feedback sessions and async Notion comments from design partners.

06 — Team Leadership & PM Development

Building the team infrastructure to scale beyond the product

Communication Hub wasn't just a product delivery — it became the vehicle through which I built Workllama's PM team capability. As the team grew to 3–5 PMs, I recognised that without shared processes, we'd lose consistency and speed.

What I built for the team

📘
PM Onboarding Playbook
Built a structured 30-60-90 day onboarding guide for incoming PMs covering Workllama's product architecture, customer segments, stakeholder map, and prioritisation principles. Reduced time-to-first-feature from ~8 weeks to under 4 weeks for two subsequent hires.
🔍
Weekly Product Review Sessions
Ran structured biweekly critique sessions where junior PMs presented PRDs and feature briefs for peer and senior review. Created a safe feedback environment using a "warm-cool-hard" critique format borrowed from design crit practice — grounding every PM decision in user evidence, not opinion.
🗂
Discovery-to-Delivery Framework
Documented the end-to-end PM process used on Communication Hub into a repeatable framework: problem framing → discovery → opportunity sizing → PRD → stakeholder alignment → beta → GA. Became the team's default operating model for all subsequent 0→1 features.
🎯
Mentoring & Career Development
Paired with 2 junior PMs on Communication Hub as stretch assignments — one owning the analytics module, one owning the Chrome plugin. Ran monthly 1:1s focused on career growth, not just task status. Both took on independent feature ownership within 6 months.

PM Onboarding Playbook — contents

  • Product architecture & platform overview
  • Customer segment map & ICP definitions
  • Stakeholder directory & relationship guide
  • Prioritisation principles (RICE + strategic fit)
  • PRD template with worked example

  • Common anti-patterns to avoid

Discovery-to-Delivery framework — stages

  • Problem framing & hypothesis definition
  • User discovery (interviews + shadowing)
  • Opportunity sizing & business case
  • PRD + design brief creation
  • Engineering & stakeholder alignment
  • Beta program design & feedback loops
  • GA launch + post-launch measurement
07 — What I Learned

Lessons that shaped how I lead product teams

Scope discipline is a leadership act. Cutting 40% of V1 features wasn't a failure of ambition — it was the decision that let us ship in 10 weeks and learn from real users. Junior PMs often confuse completeness with quality. The playbook I built explicitly teaches ruthless scoping.

Customer Success is a product team, not a support team. CS brought me the churn signals that made the business case undeniable. Building that partnership early — and formalising it into our beta process — became a repeatable pattern I codified in the discovery framework.

Adoption is a product problem, not a training problem. The 70% adoption rate didn't come from training decks — it came from in-app tooltips, a Chrome plugin that met recruiters where they already worked, and CS-led onboarding sessions. Distribution is part of the product.

The best way to grow junior PMs is to give them real ownership, not observation. Assigning the analytics and Chrome plugin modules to junior PMs — with coaching, not hand-holding — accelerated their growth faster than any training programme would have.
