How GrowthSpree Ran an ABM Program That Validated Fable's ICP, Problems & Positioning
Fable had a sharp hypothesis about who it served and why — but no proof. Through a four-geography, conversation-led ABM program across email and LinkedIn, GrowthSpree engaged 885 prospects at 397 companies, gathered direct decision-maker feedback, and confirmed all four hypotheses: ICP, problem statements, messaging, and positioning.
Key Takeaways
Fable, a pre-seed team-communication startup, hired GrowthSpree to run an ABM campaign as a research instrument — testing its assumptions about buyers, problems, messaging, and positioning before scaling. Across four geographies, the program turned outreach into evidence and validated every core hypothesis.
- 885 prospects across 397 companies reached in 4 geographies: North America, Singapore, Australia, India.
- All 4 hypotheses validated: ICP, problem statements, messaging, and positioning.
- ICP confirmed: Growth Marketing & Product Marketing roles at 51–200 employee, growth-stage firms.
- Validated pain point: improving team communication and streamlining workflows.
- Australia punched above its weight — an 11.11% interest rate vs 1.12% in North America.
- Winning message: team collaboration + communication optimization, tuned to growth-marketing pain.
The Mission
Fable is a cutting-edge platform that simplifies and streamlines communication for teams through a single, integrated solution. As a pre-seed company, its biggest growth risk wasn't building the product — it was building it for the wrong buyer. GrowthSpree was brought in to find out, for certain, who that buyer was.
The Challenge
Fable had a clear hypothesis about its Ideal Customer Profile, the problems it solved, and how it should talk about itself — but none of it was proven in the market. With a tiny early-stage team and no room to waste effort, the company needed direct feedback from real decision-makers across multiple geographies to validate (or correct) its ICP, problem statements, messaging, and positioning before pouring budget into go-to-market.
Key Challenges Identified
Our Strategy
We designed the campaign as a structured experiment with one job: validate four hypotheses — ICP, problem statements, messaging, and positioning — by getting Fable in front of the exact decision-makers it believed it served, and listening carefully to what came back. Channels: email and LinkedIn. Geographies: North America, Singapore, Australia, and India. Primary KPI: qualified, interested conversations and the qualitative signal inside them.
The GrowthSpree Approach
GrowthSpree ran a combined outreach strategy across Lemlist (personalized email) and Dripify (LinkedIn connection requests and InMail), segmenting by the roles Fable wanted to test — Growth Marketers, Product Marketing Managers, and VPs of Marketing — at growth-stage companies sized 51–1,000 employees. Every region ran as its own controlled cohort so we could compare response and interest rates cleanly.
Crucially, this wasn't a volume play. Every reply was mined for qualitative signal: which roles leaned in, what pains they named, and which messaging angles earned a response. That turned outreach into a research instrument — producing evidence Fable could act on, not guesses.
How GrowthSpree Saved the Day
Hypothesis-Led Targeting
We built target lists around the exact roles and company sizes Fable wanted to test — Growth Marketing, Product Marketing, and VPs of Marketing at 51–1,000 employee growth-stage firms — so every reply was a data point on the ICP.
Dual-Channel, Multi-Geo Outreach
Lemlist drove personalized email while Dripify ran LinkedIn connection requests and InMail — deployed as four separate regional cohorts across North America, Singapore, Australia, and India for clean comparison.
Conversation-Led Validation
Every interested reply was treated as research — capturing which pains buyers named and which messaging resonated. The result was direct evidence on Fable's problem statements and positioning.
Performance by Region: A Four-Market Read
Running each geography as its own cohort revealed where Fable's message landed hardest — and which roles leaned in.
By far the largest cohort — 358 companies and 806 prospects — giving the most statistically meaningful read on who responds and why.
Star insight: Growth Marketing made up 66.6% of interested leads, and the 51–200 employee size range drove 77.8% of all interest — the single clearest confirmation of Fable's ICP.
Just 16 companies and 27 prospects, yet it returned the best reply and interest rates of any geography in the program.
Star insight: Product Marketing was the most common interested title here (66.6%), and the response rate far outpaced other regions — a market worth prioritizing for the next phase.
14 companies and 39 prospects produced a healthy double-digit reply rate and clear interest concentrated in one role.
Star insight: 66.6% of interested leads came from Growth Marketing roles — the same role signal as North America, reinforcing Fable's value proposition for growth-oriented teams.
The smallest cohort — 9 companies and 13 prospects — but engagement held up even at low volume.
Star insight: High engagement despite a small sample suggests a niche audience worth a more localized approach in future campaigns.
The Results
Growth/Product Marketing
51–200 Employee Firms
(4 Geographies)
Across four geographies, GrowthSpree reached 885 prospects at 397 companies, earning a 4.75% reply rate and 16 interested conversations. More importantly, the data validated all four hypotheses: the ICP (Growth & Product Marketing at 51–200 employee firms), the core problem (team communication & workflow efficiency), and the winning message (collaboration & communication optimization).

What Made It Work
Four lessons from turning an ABM campaign into a validation engine.
Confirm the ICP, don't assume it
Interested leads concentrated in Growth Marketing and Product Marketing across every major region — validating Fable's hypothesis with evidence instead of leaving it to guesswork.
The mid-market sweet spot is real
51–200 employee, growth-stage firms drove the bulk of engagement — 77.8% of North American interest — confirming where Fable's solution fits best.
Small markets can punch above their weight
Australia's 11.11% interest rate dwarfed North America's 1.12%. Raw volume isn't everything — efficiency per prospect reveals where to lean in next.
Validate the language before you scale spend
Messaging built on team collaboration and communication optimization resonated most, confirming Fable's problem statements and positioning ahead of any budget scale-up.
