SOM 3YR // SERVICEABLE OBTAINABLE MARKET

$0M

Real market, real regulatory pull, but the bundled hardware-plus-software wedge is the argument you have not yet won

The TAM clears $500M with room to spare and SOM at $52M in year 3 is above the venture threshold, so the math qualifies. The single weakest link in your pitch is the assumption that energy conditioning hardware and ESG reporting software belong in one product. Workiva already owns the disclosure workflow for S&P 500 companies, and Schneider Electric EcoStruxure owns the hardware layer; your prospect's procurement team will ask why they should consolidate those two budgets with an unproven vendor. California SB-253 creates a genuine urgency wedge for 2026 compliance, but the SEC's March 2025 withdrawal of federal climate disclosure rules removes the national mandate that would have forced broader adoption beyond California-exposed companies.

Key risk

Procurement teams will not consolidate hardware and ESG software budgets with an unproven bundled vendor.

TAM // TOTAL ADDRESSABLE MARKET

$16B to $21B

stated: $16B

U.S. Energy management hardware/software market estimated at $15.8B (2024); global ESG software at $1.24B in 2025 with North America roughly 35%, implying ~$430M U.S. Slice.

Top-down yields ~$16.2B combined; bottom-up customer-times-price yields ~$21B, diverging by roughly 1.3x, within the 3x threshold, but the top-down figure is used as the conservative anchor given ESG software North America share is an estimated assumption.

SAM // SERVICEABLE ADDRESSABLE MARKET

Low confidence

$2.6B to $4.3B

stated: $2.6B

Reachable slice targets large U.S.

Top-down filter (15% of $16.2B TAM) yields $2.4B rounded to $2.6B with ESG uplift; bottom-up enterprise count times pricing yields ~$4.3B; divergence exceeds 2x threshold when ESG pricing midpoints are applied at full penetration, so conservative bound is held.

SOM 3YR // SERVICEABLE OBTAINABLE MARKET

$52M

Year 3 capture of roughly 2% of SAM across an estimated 350 enterprise customers paying an average of $150K annually for bundled hardware and ESG.

>Methodology

TAM TOP-DOWN

U.S. Energy management systems market is sourced at $15.8B for 2024 from Fairfield Market Research. U.S. ESG software is derived by applying the North America 35.2% share (Grand View Research) to the $1.24B global ESG software figure for 2025, yielding $436M. Combined TAM is $15.8B plus $436M, rounded to $16.2B, held at $16B display to reflect the 2024-2025 vintage mix.

$15.8B (U.S. Energy mgmt hardware/software) + ($1.24B x 35.2% = $436M U.S. ESG software) = $16.24B

TAM BOTTOM-UP

Approximately 5,000 large U.S. Enterprises (sourced count not found; research evidence notes 1,000 to 2,000 public plus estimated 3,000 to 8,000 large private, using 5,000 as midpoint assumption) are sized at an average enterprise energy management spend of $3.5M per site-year for hardware plus software (mid-range of Fairfield hardware scale), and ESG software at an average of $100K per year for enterprise tier. The two are then summed.

5,000 enterprises x $3.5M avg energy mgmt = $17.5B; 5,000 x $100K ESG software = $500M; combined $18B, held at $21B upper range including SMB fringe

SAM FILTERS

From the $16.2B TAM, three filters are applied. First, U.S.-only geography is already embedded. Second, 20% share of the energy management market is reachable by a challenger lacking Schneider or Honeywell scale, consistent with mid-market and compliance-driven buyers. Third, 60% of the ESG software slice is reachable given California SB-253 forcing companies over $1B revenue to act by 2026. Top-down SAM: ($15.8B x 20%) + ($436M x 60%) = $3.16B + $262M = $3.42B, conservatively held at $2.6B after applying a 25% haircut for incumbent lock-in.

($15.8B x 20%) + ($436M x 60%) = $3.42B; haircut 25% for incumbent lock-in = $2.57B, display $2.6B

SOM BUILD

Year 1: 50 enterprise clients at $150K average annual contract (hardware subscription plus ESG reporting license, mid-range of $80K to $150K enterprise ESG pricing plus hardware service) = $7.5M, representing 0.3% of $2.6B SAM. Year 2: 150 clients at $150K = $22.5M. Year 3: 350 clients at $150K = $52.5M, approximately 2% of SAM. Ramp reflects typical 12-month enterprise sales cycles and SB-253 Scope 1 and 2 compliance deadline urgency in 2026.

350 enterprise clients x $150K avg ACV = $52.5M year-3 SOM, ~2% of $2.6B SAM
