# Technology Market Share, Growth & Migration Intelligence

> Analyze technology market share, quarterly growth, 20-year adoption trends, ICP patterns, and migration analysis across categories. Compare competing technologies with real data from 50M+ domains. The kind of intelligence HG Insights charges $50K+/year for — starting at $89/month.

TechnologyChecker provides market intelligence with 20+ years of historical data across [40,000+ technologies](/features/technologies) on 50M+ domains. Analyze market share within categories, compare quarterly growth rates, track long-term adoption trends, build ICP profiles from real data, and understand migration patterns. HG Insights charges $50K+/year for this kind of data. TechnologyChecker starts at $89/month.

## Market share analysis

Drill into any technology category to see how market share is distributed.

<CardGroup cols={2}>
  <Card title="Donut chart" icon="chart-pie">
    Top 8 technologies with percentage breakdowns, color-coded legend, and total website count displayed in the center.
  </Card>

  <Card title="Top 20 table" icon="ranking-star">
    Ranked list with website counts and visual progress bars scaled relative to the leader's market share.
  </Card>
</CardGroup>

## Quarterly growth

Track the biggest movers between quarters with a horizontal bar chart showing the top 5 technologies by absolute change.

* **Green bars** indicate positive growth
* **Red bars** indicate decline

Each data point includes:

| Field                  | Description          |
| ---------------------- | -------------------- |
| Technology name        | With icon            |
| Previous quarter count | Starting baseline    |
| Current quarter count  | Current measurement  |
| Absolute change        | Net difference       |
| Percentage change      | Relative growth rate |

## How to track adoption trends over time

A stacked area chart tracks the top 5 technologies by adoption over configurable time ranges:

<Tabs>
  <Tab title="3 years">
    Default view with monthly data points. Best for tracking recent momentum and short-term shifts.
  </Tab>

  <Tab title="5 years">
    Medium-term trend analysis. Good for identifying sustained growth versus temporary spikes.
  </Tab>

  <Tab title="7 years">
    Long-term adoption patterns. Reveals technology lifecycle stages (growth, maturity, decline).
  </Tab>

  <Tab title="10 years">
    Full historical perspective. Shows complete market evolution including technology replacements.
  </Tab>
</Tabs>

The chart uses formatted counts (1.2M, 546K) on the Y-axis and monthly labels ("Jan 2024") on the X-axis.

## ICP pattern analysis

Use 20+ years of historical data to find which technology combinations correlate with your best customers, then find more companies matching those patterns.

<AccordionGroup>
  <Accordion title="Build ICP technology profiles" icon="bullseye">
    Analyze which technologies your highest-LTV customers share. Build scoring models based on empirical technology patterns rather than assumptions.

    *Example: "Our highest-LTV customers use Stripe + Segment + a headless CMS. TechnologyChecker finds 2,400 companies matching this pattern that aren't yet customers."*
  </Accordion>

  <Accordion title="Technology maturity segmentation" icon="layer-group">
    Segment prospects by technology sophistication. Companies using modern infrastructure (headless CMS, API-first tools, automation platforms) signal different buying behavior than those using legacy stacks.
  </Accordion>

  <Accordion title="Growth stage correlation" icon="chart-line">
    Identify which technology adoption patterns correlate with company growth stages. Early-stage companies have different tech stacks than scale-ups — use this for market segmentation and targeting.
  </Accordion>
</AccordionGroup>

## Migration pattern analysis

Where do companies go when they leave a technology? Competitive displacement intelligence backed by real data.

* **Replacement tracking:** Which technology do companies adopt after dropping Technology X?
* **Migration direction:** Is the market moving toward or away from specific tools?
* **Competitive displacement:** Which products are gaining share from which incumbents?
* **Industry-specific patterns:** How do migration patterns differ by company size and vertical?

*Example: A VC firm tracking the project management space sees that 60% of companies leaving Asana move to Linear or Notion, while Linear's subscriber growth rate is 3x faster than Asana's in the 100-500 employee segment.*

## Frequently asked questions

<AccordionGroup>
  <Accordion title="How do I compare two technologies?">
    Use the category market share view to see ranked positioning, or query `GET /v1/technology/{id}/stats` for each technology to compare active domain counts. For trend comparison, use `GET /v1/technology/{id}/history` with the same time range for both technologies.
  </Accordion>

  <Accordion title="What time ranges are available for trend data?">
    The platform offers 3-year, 5-year, 7-year, and 10-year views with monthly granularity. The API returns the full history (up to 20+ years) with `GET /v1/technology/{id}/history`, letting you define your own time ranges.
  </Accordion>

  <Accordion title="How is market share calculated?">
    Market share is calculated as the percentage of active domains using a technology relative to the total domains in that category. The donut chart shows the top 8 technologies with the rest grouped as "Other." The ranked table shows the top 20 with visual progress bars.
  </Accordion>

  <Accordion title="Can I use this data for investment research?">
    Yes. 20-year historical data is well suited for market sizing, competitive mapping, and growth trajectory analysis. Track subscriber growth rates to spot breakout technologies, monitor churn rates to identify declining products, and analyze migration patterns for competitive displacement intelligence. See [investment use cases](/use-cases#investment-and-due-diligence) for detailed workflows.
  </Accordion>

  <Accordion title="How does this compare to HG Insights market intelligence?">
    HG Insights provides enterprise-grade technology market intelligence (100K+ technologies, IT spend data, AI Copilot) for $50K+/year.
