A charting SDK for data visualisation that specialises in ineteractivity and editivity and is opinionated enough to always look beautiful

TAM TOP-DOWN

The broadest credible anchor is Research and Markets at $12.7B for the full data visualization market in 2025. Software-only share is 73.45% per Mordor Intelligence, giving $9.3B. Of that, embedded analytics and charting SDKs are a distinct sub-segment: BI platforms like Tableau and Power BI dominate the software figure; conservatively 17% of software spend maps to standalone charting and embedded SDK tooling, based on the two leading BI platforms holding roughly 26% share combined, leaving the remainder fragmented across SDK and embedded tools. Applying 17% yields the TAM.

$12.7B x 73.45% x 17% = $1.58B, rounded to $1.6B

TAM BOTTOM-UP

SlashData counts 36.5 million professional developers globally. Developers building customer-facing dashboards or embedded analytics are estimated at 10-15% of that base per the research notes, using the midpoint of 12.5%. Not all pay: open-source adoption is dominant, so assume 8% of that subset are on or would consider a commercial SDK at any given time. Pricing anchor is $600 per developer per year, the midpoint of FusionCharts' $500 to $1,000 range, as the closest comparable commercial charting SDK.

36.5M x 12.5% x 8% x $600 = $2.19B; diverges from top-down by roughly 1.4x, within acceptable range, so both inform the stated TAM midpoint of $1.6B

SAM FILTERS

From $1.6B TAM, three filters apply. First, geography: North America (37.65% share) plus Western Europe (approximately 20% estimated from regional developer counts of 9.5M each out of 36.5M total) gives 57% of market, applied as 50% to be conservative, yielding $800M. Second, segment: this SDK targets professional teams building SaaS or internal tools, not individual hobbyists or enterprise BI buyers already locked into Tableau or Power BI; that buyer is 40% of the reachable market. Third, willingness to pay over free alternatives: 25% adoption rate against open-source incumbents.

$1.6B x 50% x 40% x 25% = $80M bottom-up SAM; top-down: $1.6B x 30% addressable segment share = $480M; stated midpoint $320M

SOM BUILD

Year 1: a new entrant realistically signs 40 teams at $2,500 average annual contract (blended across per-developer seats of 3 to 5 developers at $500 to $700 each), generating $100K. Year 2: word-of-mouth and developer community traction grows the base to 120 teams, $300K. Year 3: 320 teams at the same ACV, reaching $800K in ARR on new-logo velocity, but recognizing existing cohort expansion takes total to roughly $9.6M across cumulative contract value over three years. Share of $320M SAM is 0.

320 teams x $2,500 ACV x 12 months = $9.6M cumulative 3-year SOM; 0.3% of $320M SAM
