Untrained ERP users enter bad data that disrupts pipelines and produces incorrect report numbers, and the solo DE gets blamed for it.
A lightweight middleware that validates data at the ERP/source level against configurable business rules, blocks or flags bad entries, and alerts the DE before dirty data propagates downstream.
Subscription — $99-$299/mo based on data sources connected and validation rules.
This is a hair-on-fire problem. The Reddit post and pain signals describe a scenario where the DE is personally blamed for data quality issues caused by others. It's career-threatening ('work quality got hit'), emotionally draining ('death by paper cuts'), and there's no existing tool that solves it at the right layer. Every solo DE at an SMB with an ERP has lived this exact nightmare. The pain is acute, recurring, and has no current workaround beyond manual vigilance.
TAM is niche but real. There are ~500k-1M data engineers globally, with maybe 100-200k at SMBs dealing with ERP data quality issues. At $200/mo average, that's a $240M-$480M addressable market ceiling. However, realistic serviceable market is much smaller — maybe 10-30k teams initially who are (a) at SMBs, (b) using common ERPs, (c) aware enough to seek a solution. This is a solid $20-50M SAM. Not venture-scale but excellent for a bootstrapped or small-team business.
Solo DEs at SMBs have limited tool budgets but $99-299/mo is in the 'expense it on a credit card' range. The value prop is clear: prevent the fire vs. fight the fire. Companies already pay for Fivetran, dbt Cloud, monitoring tools — this slots into existing spend patterns. The risk: some DEs will try to build this themselves with dbt tests + custom scripts (the 'build vs. buy' inertia in this persona is strong). Price anchoring against Monte Carlo ($30k+) makes $299/mo feel like a steal for similar peace of mind.
This is the hardest part. Building 'middleware that validates at the ERP/source level' is architecturally challenging. ERPs like SAP and NetSuite are notoriously closed ecosystems with limited real-time hooks. Options: (1) API-based polling/webhooks where available (NetSuite has SuiteScript, SAP has BAPIs/IDocs), (2) database-level triggers on the ERP's underlying DB (risky, unsupported), (3) proxy layer on the ERP's API calls. Each ERP requires custom integration work. A solo dev could build an MVP for ONE ERP (e.g., NetSuite via SuiteTalk API) in 6-8 weeks, but multi-ERP support is a long road. The 'block bad entries' feature is especially hard — flagging/alerting is much more feasible for MVP.
The gap is real and well-defined. Every existing tool operates post-ingestion (warehouse/pipeline layer). ZERO tools validate at the ERP input/source layer in real-time for SMBs. This is a genuinely underserved niche. The closest alternatives require the DE to build custom validation scripts, which is exactly the 'death by paper cuts' problem. Enterprise MDM tools exist but are wildly overpriced and overbuilt for this audience. There's a clear blue ocean at the intersection of 'ERP input validation' + 'solo DE workflow' + 'SMB pricing'.
Extremely strong subscription fit. Data quality is a continuous, never-ending problem — it gets worse as companies grow and add users. Once validation rules are configured, switching costs are high (rules encode institutional business logic). The tool becomes more valuable over time as more rules accumulate. Usage grows naturally with data volume and team size. This is infrastructure-grade stickiness with SaaS economics. Churn should be very low once embedded.
- +Genuinely unsolved problem — no tool validates data quality at the ERP input layer for SMBs
- +Extremely high pain intensity with clear emotional resonance (DE gets blamed for others' mistakes)
- +Strong recurring/subscription fit — data quality is an ongoing, worsening problem
- +Clear pricing sweet spot ($99-299/mo) that's below enterprise tools but sustainable
- +Growing market tailwinds: more SMBs adopting ERPs, more solo DE roles, shift-left data quality movement
- +High switching costs once business rules are encoded in the system
- !ERP integration complexity is the #1 risk — SAP/NetSuite are closed ecosystems with limited real-time hooks, and each requires custom integration work that could balloon scope
- !The 'block bad entries' feature may be technically impossible for some ERPs without invasive customization, forcing a pivot to 'detect and alert' which is less differentiated
- !Solo DEs are technically sophisticated and may prefer to build custom validation scripts rather than pay for a tool (strong DIY bias in this persona)
- !Market is niche — if growth stalls at $1-3M ARR, it may not justify the ongoing ERP integration maintenance burden
- !ERP vendors (SAP, Oracle/NetSuite) could add native data validation features, though historically they move slowly on UX/quality tooling

Traditional data quality / MDM
Start with ONE ERP only — NetSuite is the best choice (strongest API, largest SMB footprint, most accessible developer ecosystem). MVP scope: (1) Connect to NetSuite via SuiteTalk/REST API, (2) let the DE define validation rules via a simple YAML or web UI (e.g., 'Customer.industry must be from approved list', 'Invoice.amount must be > 0', 'Order.ship_date must be after order_date'), (3) poll for new/modified records on a short interval (5-15 min), (4) flag violations in a dashboard and send Slack/email alerts to the DE, (5) generate a weekly 'data quality report card' the DE can share with management to prove the problem. Do NOT attempt to block entries in MVP — alerting is enough to validate the concept and is 10x easier to build.
Free tier (1 data source, 10 rules, email alerts only) -> Starter $99/mo (unlimited rules, Slack integration, 1 ERP connection) -> Pro $199/mo (multiple connections, custom rule templates, weekly reports, API access) -> Team $299/mo (multi-user, role-based access, audit log, priority support). Upsell path: charge per additional ERP connection ($99/mo each) as companies grow. Long-term: marketplace for pre-built rule templates by industry (manufacturing, retail, etc.).
8-12 weeks to MVP with NetSuite integration. 12-16 weeks to first paying customer (need beta users for 4-6 weeks to validate rules engine and build case studies). Fastest path: find 3-5 solo DEs at NetSuite shops from Reddit/data engineering communities, offer free beta, convert to paid at $99/mo within 3 months. Realistic first $1k MRR in 4-6 months.
