Resonance

What do they actually do

Resonance offers a no‑code tool for product and growth teams to run in‑product campaigns like upsells, feature announcements, and onboarding messages. It includes a visual builder, audience targeting and frequency controls, A/B experiments, and analytics to track performance YC profile site.

Teams install a lightweight snippet/integration, build and preview campaigns in their live UI, set impression caps to avoid overlaps, and store high‑performing content for reuse. Early users are product‑led startups and SMBs that want faster iteration than general messaging suites provide YC profile site.

The product is currently sold via demos rather than self‑serve signup; pricing and detailed docs are not publicly listed, which suggests a hands‑on, pilot‑driven onboarding motion at this stage site.

Who are their target customer(s)

• Product managers at early-stage, product-led startups: They need to run in‑product campaigns but lack engineering bandwidth, so copy/targeting changes are slow and experiments stall YC profile site.
• Growth or marketing leads at SMB SaaS companies: They coordinate many promotions across tools and spreadsheets, struggle to scale experiments, and can’t reliably reuse winning copy across the product YC profile site.
• Onboarding/activation owners: They face message overload and can’t enforce frequency caps or resolve conflicts across teams, causing users to see overlapping prompts and drop off.
• Customer success/retention owners focused on NRR: They can’t consistently tie in‑product messages to outcomes and lack a system to preserve and redeploy high‑performing content YC profile.
• Small engineering teams/founders avoiding homegrown systems: They don’t want to build/maintain internal messaging tools or handle one‑off requests and integrations that distract from core product work site.

How would they acquire their first 10, 50, and 100 customers

• First 10: Run high‑touch pilots sourced via YC/warm intros and inbound demos; handle installation and setup to show a live campaign in 4–6 weeks and trade discounted pilots for clear success metrics and testimonials YC profile site.
• First 50: Package the pilot into a repeatable quick‑win offer and scale targeted outbound to SMB growth/marketing leads, partner with agencies, and host webinars using early case studies; publish integration guides to reduce setup friction site.
• First 100: Introduce a semi self‑serve flow with templates, integration listings, and a paid success tier for higher‑touch pilots; drive inbound via SEO on in‑product experimentation/frequency control, paid PM/growth ads, and PR/YC amplification of customer stories site.

What is the rough total addressable market

Top-down context:

MarTech is very large (~$552B in 2025) but broad; Resonance sits in the smaller product adoption/digital adoption niche, commonly estimated in the low billions today Grand View Research FutureMarketReport DMR.

Bottom-up calculation:

Assume ~20k product‑led/SaaS SMBs as the practical target and ARPC scenarios of $5k, $20k, and $60k; that implies ~$100M, ~$400M, and ~$1.2B in annual TAM, respectively. SaaS company counts reference ~30–40k globally, narrowed to a realistic buyer subset DemandSage.

Assumptions:

• ~20k target companies that actively run in‑product campaigns (subset of global SaaS).
• ARPC ranges: $5k (SMB light use), $20k (SMB/mid‑market), $60k (larger mid‑market/enterprise bundles).
• Pricing and buyer mix may shift as the product matures from demo‑driven pilots to broader adoption.

Who are some of their notable competitors

• Intercom: Broad messaging platform for support and in‑app communication; its Product Tours and in‑app messages overlap with no‑code onboarding and announcements docs.
• Appcues: No‑code product adoption tool for tooltips, modals, and flows with measurement; overlaps on builder/experiments but emphasizes adoption playbooks over automated content reuse product.
• Pendo: Product experience platform bundling analytics, in‑app guides, feedback, and replay; stronger on analytics/enterprise needs, heavier than a focused campaign/content layer overview.
• Braze: Omnichannel engagement (email, push, in‑app) with personalization at scale; overlaps on in‑app content and targeting but is broader lifecycle marketing docs.
• Userpilot: No‑code product growth tool for onboarding and micro‑experiments; direct overlap on builder + targeting + testing, less focused on automated content reuse docs.
