Startups are founder bets on markets that don’t exist yet. You’re backing a person, not a business-because there’s no business to audit yet. That’s why due diligence matters. Rigorous DD separates 10x wins from total wipeouts. This framework (Nextep’s DD playbook) flags 70% of failure signals before your cheque clears.

Why Due Diligence Matters for Startups
M&A DD audits financials, contracts, compliance history. Startup DD is different. No 5-year P&L to verify. No track record. Maybe no revenue. Instead: founder capability, product-market fit, unit economics, execution risk. Different animal.
90% of Indian startups fold within 5 years. Rough odds. But investors running rigorous DD cut their write-off rate by 40%. That’s material portfolio upside.

The Five-Dimension DD Framework
Our framework covers five critical dimensions. Each has a specific purpose, timeline, and checklist. Most startups will require 30-60 days of structured DD work.
1. Financial Due Diligence
Financial DD for startups focuses on unit economics, cash burn, and capital efficiency-not historical earnings. You’re assessing whether the company can reach profitability or cash-flow break-even before running out of money.
Financial DD Checklist (15 items)
- Revenue quality: Recurring (SaaS, subscriptions) vs non-recurring (project work)? Customer concentration risk (top 3 customers >50%)?
- Unit economics: CAC (Customer Acquisition Cost), LTV (Lifetime Value), LTV:CAC ratio (>3:1 is healthy)
- Gross margin: For SaaS, should be >70%. For hardware, >40%. Improving or declining?
- Burn rate: Monthly cash burn. Runway remaining at current burn?
- Cash runway: Months of cash left. Burn rate trending down?
- Bookings vs revenue recognition: Deferred revenue (good indicator of future stability)
- Working capital: AR/AP days. Are customers paying on time? Are suppliers extending terms?
- Churn rate: Customer churn <5% monthly is healthy for most SaaS. Increasing churn = red flag
- CAC payback period: Months to recover CAC. Should be <12 months for healthy SaaS
- Marginal unit economics: Cost to serve next customer vs revenue from that customer
- Tax compliance: IT returns filed (3 years). TDS compliance. GST filings on time?
- Statutory dues: Any unpaid GST, PF, or TDS? Any tax notices pending?
- Bank statements: Last 24 months. Verify cash flow matches reported financials
- Traction timeline: When did revenue start? Growth rate (MoM, QoQ). Acceleration or deceleration?
- Funding history: Previous rounds (size, terms, investor names, valuations). SAFE notes issued?
2. Legal Due Diligence
Legal DD verifies that the company owns what it claims to own and is not hiding liabilities. Startups often have sloppy legal setup; your job is to identify and quantify the risk.
Legal DD Checklist (12 items)
- Certificate of incorporation: Registered with MCA. Incorporation date. Current director list.
- MOA/AOA: Memorandum of Association, Articles of Association. Any restrictive clauses? Preferential share classes?
- Cap table: Cap table as of your investment date. All shareholders listed. Previous ESOP vesting schedule?
- Intellectual property (IP): Patents filed? Trademarks registered? Copyright assignments in place (from founders/developers)?
- IP indemnity: Have they ever received a cease-and-desist letter? Pending IP litigation?
- Material contracts: Customer contracts, supplier agreements, partnership deals. Any unfavourable terms? Termination clauses?
- Founder agreements: Founder equity split. Vesting schedule (4-year vest with 1-year cliff is standard). Non-compete/non-solicit clauses?
- Employment law compliance: Salary structures documented. Leave policies compliant. Are there undocumented employees?
- Regulatory approvals: Does the business model require specific licenses? Obtained or pending?
- Litigation history: Any pending lawsuits (commercial, labour, IP)? Settled claims?
- Corporate governance: Board composition. Board meeting minutes. Investor communication record.
- Previous term sheets: Any earlier DD findings? Regulatory notices? Hostile board actions?

3. Technical Due Diligence
Technical DD evaluates the product’s scalability, security, and durability. A startup with brilliant founders but broken tech will still fail. Conversely, a mediocre team with solid tech can hire and scale.
Technical DD Checklist (10 items)
- Tech stack: Languages, frameworks, databases. Is it modern? Maintainable by team or consultant-dependent?
- Architecture: Monolith or microservices? Can it scale to 10x user load? Single points of failure?
- Cloud infrastructure: AWS/GCP/Azure or on-premise? Cost efficiency? Auto-scaling configured?
- Code quality: Code reviews enforced? Test coverage >70%? Continuous integration/deployment pipeline?
- Security: Encryption in transit and at rest? Compliance audits (SOC 2, ISO 27001)? Vulnerability scans?
- Data privacy: GDPR/CCPA compliance (if relevant). Data residency. Backup and disaster recovery protocols?
- Technical debt: Is the codebase a mess? Is the team spending 50%+ time on legacy fixes vs new features?
- Performance: API latency. Database query optimization. CDN usage. Load test results available?
- Third-party dependencies: How many external APIs/libraries? Vendor lock-in risk?
- Product roadmap: 12-month technical roadmap. Resource allocation realistic? Or over-committed?
4. Market Due Diligence
Market DD validates the opportunity. A brilliant team solving a tiny market will fail. A mediocre team in a boom market might succeed. TAM (Total Addressable Market) validation is critical.
Market DD Checklist (10 items)
- TAM/SAM/SOM: Total Addressable Market, Serviceable Available Market, Serviceable Obtainable Market estimates (with methodology disclosed)
- TAM growth rate: Is the market growing? CAGR 15%+ is healthy. Stagnant markets = commodity risk
- Competitive market: Direct competitors (feature comparison table). Indirect competitors. Who’s gaining/losing share?
- Competitive positioning: What’s the startup’s differentiation? Defensible (tech, network effects, cost) or fleeting (brand)?
- Customer pain point: Do customers actually care about this problem? Willingness to pay? Or solving a “nice-to-have”?
- Customer concentration: Top 5 customers >50% of revenue? Sticky customers or at-risk?
- Market maturity: Are customers already buying (existing budget) or do you need to create the category?
- Regulatory tailwinds/headwinds: Are regulations helping or hurting the market? Compliance cost burden?
- Industry analyst coverage: Gartner/Forrester reports. Third-party validation of market size?
- Adjacent expansion: Can the startup expand to adjacent verticals/geographies? Is the current TAM just the start?
5. Team Due Diligence
Most startup failure is founder/team failure, not product or market failure. Evaluate founder track record, domain expertise, fundraising discipline, and succession risk.
Team DD Checklist (8 items)
- Founder background: Previous successful exits? Failed companies? Domain expertise in the space? Why this problem, now?
- Co-founder dynamics: Do they complement each other? Technical + business skills? Or all business, all technical? Reference calls with past colleagues?
- Key person risk: Is the company too dependent on one founder? What happens if the CEO leaves?
- Organisational structure: Head count by function. Who are the key hires? Track records?
- ESOP pool: What % is reserved for future hires? Vesting cliffs clear to current employees?
- Board composition: Who’s on the board? Investor directors? Independent directors? Are they value-add or passengers?
- Advisory board: Reputable advisors? Engaged or nominal? Reference check the advisors’ involvement
- Culture & values: Does the team have a clear mission? High employee turnover? Founder-friendly or founder-hostile environment?
DD Timeline & Allocation
A complete DD process for a Series A/B startup takes 30-60 days. Here’s a typical allocation:
Average DD timeline for Series A/B
| Dimension | Duration (Days) | Primary Resource |
|---|---|---|

| Legal DD | 7-10 | External counsel (โน3-5 L) |
| Technical DD | 5-7 | External CTO/tech audit firm (โน2-3 L) |
| Market DD | 5-7 | In-house analyst + customer interviews |
| Team DD | 3-5 | In-house + founder reference calls |
| Remediation & closing | 3-5 | Project manager + counsel |
Total external spend: โน5-15 L for professional DD (legal + technical audit).
Common Red Flags Matrix
| Dimension | Red Flag | Severity | Action |
|---|---|---|---|
| Financial | LTV:CAC <2:1 or declining unit economics | ๐ด Critical | Pass or massive discount to valuation |
| Monthly churn >5% (SaaS) | ๐ด Critical | Pass. Product-market fit is broken. | |

| Team | Founder has history of failures with no learning / accountability | ๐ด Critical | Pass. Red flags on founder integrity. |
| Key person (CEO or CTO) is a bottleneck; no backup plan | ๐ก High | Require succession plan or restructure |
India VC Landscape: Why DD Matters More
India’s VC market has grown rapidly. In 2025, we saw 900+ VC deals across all stages. The quality spread is massive: early-stage startups range from world-class to completely broken. Rigorous DD is what separates winners from write-offs.
India VC deals in 2025
Also, India-specific risks increase DD burden:
- Regulatory uncertainty: Fintech, crypto, e-commerce have historically volatile policy environments. DD must assess regulatory risk explicitly.
- FDI/RBI restrictions: Some sectors face FDI caps or RBI scrutiny. Tax authorities scrutinise VC-backed companies. Ensure compliance DD includes tax counsel review.
- Labour law complexity: Employment law varies by state. Startups often miss GST/PF compliance. Legal DD must cover statutory compliance meticulously.
- Customer concentration in India: B2B SaaS often sells to a handful of large corporates. Customer diversification is critical to assess.
Frequently Asked Questions
Should we use external DD advisors or do it in-house?
Both. Use in-house team for financial and market DD (you know your thesis best). Use external counsel for legal DD (liability minimisation) and external CTO/tech firm for technical DD (objective assessment). External DD costs โน5-15 L but catches issues internal teams miss.
Can we do DD in 2 weeks?
Yes, for a Series A follow-on or lower-risk deal. But for new founders or novel markets, 30-60 days is worth it. Compressed DD misses red flags. Good investors take the time.
What if the startup refuses to provide information?
Pass. Non-disclosure is a red flag on founder transparency and governance. You don’t want to partner with opaque founders.
How much should DD findings impact valuation?
Significantly. A startup with perfect unit economics, clean IP, and proven market traction commands a 20-30% valuation premium over one with legal risks, churn issues, or technical debt. Use DD findings to calibrate price.
Is DD a one-time event or ongoing?
Due diligence is upfront (pre-investment). Post-investment, you have monitoring and governance-different cadence. But annual investor meetings should include a “fresh look” at critical metrics (churn, burn, cap table changes).
Key Takeaways
- Five dimensions: Financial (unit economics, burn, tax compliance), Legal (IP, cap table, contracts), Technical (scalability, security, debt), Market (TAM, competition, customer pain), Team (founder track record, org structure, key person risk).
- Checklist approach: Use the 55-item combined checklist above. 70% of failures have identifiable DD red flags-don’t miss them.
- Timeline: 30-60 days is standard. Compressed DD (2 weeks) works only for low-risk follow-ons. First-time investments deserve the full timeline.
- External resources: Spend โน5-15 L on legal and technical DD. It’s 0.5-1% of a Series A and catches 40% of potential write-offs.
- Red flags are deal-killers: LTV:CAC <2, monthly churn >5%, IP disputes, founder integrity issues-pass, don’t discount. Some risks are not investable.
- India-specific risks: Regulatory uncertainty, FDI caps, labour law complexity, customer concentration. DD must account for all five.
