Technology Development Fund (TDF)

Current status

The Technology Development Fund (TDF) is a Ministry of Defence programme executed by the Defence Research and Development Organisation (DRDO). It supports Indian industry developing defence and dual-use technologies that are not available domestically, or that have not yet been developed to an adequate level in India. The programme is connected to requirements from the Services, Defence Production, and DRDO rather than to a general-purpose startup pitch competition.

This page is a historical reference for the latest published application window confirmed on the official TDF portal. The portal listed Indigenous Development and Production of Miniature Sealed Aneroid Capsules for Aircraft Life Support System as a feasibility/RFI, open from 2026-03-18 through 2026-05-11 at 17:00. The project listing now shows no project under the open feasibility/RFI stage. Its separate DPR listings showed project-specific bids with closing dates in April 2026, which have also passed. No new deadline appears in the open-for-application listing checked for this update. The TDF scheme continues, but this specific RFI is closed and this page is an archive of that project window rather than a live invitation.

The distinction matters. TDF is a continuing scheme that identifies project requirements and may conduct feasibility studies before issuing a project definition and requesting Detailed Project Reports (DPRs). It does not have one permanent annual deadline or a single annual application cycle. A date belongs to a particular project or feasibility exercise. When the portal publishes a new requirement, that requirement and its linked procurement documents control the scope, submission route, and closing time. The deadline in this archive records the last verified feasibility/RFI opportunity; it does not mean every TDF project shared that deadline.

What the fund supports

TDF is intended for development work with a credible defence application. The official FAQ describes eligible work as technology or prototype development with potential use for the Services. The programme can cover industrial development and may involve academic or research partners, but the applicant needs to show a path to a usable output. A concept that ends at a paper, an untested demonstration, or a broad market idea is not enough by itself.

Examples of a suitable project profile include an Indian company developing a new sensor, subsystem, material, manufacturing process, embedded system, or other technology against a published defence requirement. The fit comes from the requirement and the development plan, not from using defence-related language in a proposal. A team should be able to state the user problem, the technical performance to be demonstrated, the tests required, and the route from development to qualification or production.

The scheme is also not an unrestricted operating grant. The applicant is expected to submit a defined plan, price the work under the applicable cost heads, meet milestones, preserve financial records, and respond to technical review. The official portal warns that its public project information is indicative and asks applicants to confirm dates, terms, and other details through the Defence e-Procurement (DefProc) portal or other official sources.

Funding and amount

The current TDF General Guidelines describe a tiered funding approach. Projects up to ₹10 crore may be considered for funding up to 90% of total project cost in general. Projects above ₹10 crore and up to ₹50 crore may be considered for funding up to 70% in general. The guidelines allow up to 100% funding case by case. They also state that the total development cost across required technology-development phases shall not exceed ₹50 crore; projects above that amount may be taken up after approval from the Raksha Mantri. These are scheme-level limits, not a promise that every applicant receives the maximum percentage or that every project can be priced at the ceiling. A published project definition and its procurement documents determine the budget and deliverables for an actual call.

The current General Guidelines say TDF projects typically will not exceed four years of development. The project definition may establish a shorter schedule, technical phases, milestones, and acceptance criteria. Applicants should plan to complete a defined prototype or technology outcome within the call’s schedule rather than treating the scheme-wide duration as a guaranteed project term.

Funding is milestone-based. Under the current General Guidelines, advance funding requires a bank guarantee for the same amount, except for government-owned institutions. Subsequent instalments depend on a detailed project update report, utilisation certificate and statement of expenses, a chartered accountant certificate, and recommendations from the Project Monitoring and Mentoring Group (PMMG) with Technical Committee approval. The award documents set the specific instalment schedule, and a project should budget for the reporting work needed to support each release.

Budget discipline is important. Build costs around the stated work packages, test plan, development phases, and milestone outputs. Check each call’s rules for partner contributions, allowable cost heads, taxes, equipment, and supporting quotations instead of assuming that a detail from a past project applies to a new one. Keep the technical work, timeline, and price consistent, and identify any facilities or specialist testing that must be bought from a partner. TDF releases funds against approved milestones and requires project and financial records, so applicants should account for reporting and audit responsibilities when they prepare a cost plan.

Who can apply

Published TDF vendor criteria identify several eligible Indian entity structures, including:

proprietorships;
partnerships;
limited liability partnerships; and
private limited and public limited companies; and
one-person companies.

The entity must be owned and controlled by resident Indian citizens under published vendor criteria. Foreign investment or partnership participation must not exceed 49%. A consortium or Association of Persons can apply when its composition satisfies the applicable requirements. The specific call documents govern which entities may join and how the consortium must be formed. Settle the lead agency, responsibilities, financial control, and intellectual-property arrangements before submission rather than leaving them implicit in the proposal.

Proposals are submitted by eligible entities registered as “industry” on the TDF portal or procurement platform specified for the call. The portal registration process asks applicants for entity and recognition information, and the project may have additional registration or procurement requirements. Registration is therefore a preparation step, not something to postpone until the final hour. Check current portal instructions and live project documents for the exact certificates and account type required.

Only Indian vendors are eligible under the scheme-level guidance. Industry is the development applicant; universities and research institutions can contribute when the relevant project terms allow it. MSMEs and startups are a particular focus, while the published vendor criteria and specific project documents govern whether a larger company or a particular consortium can participate. Check the relevant procurement’s eligibility clauses directly, especially for ownership, licences, debarment, consortium roles, and required registrations.

Startups should read the project-specific category carefully. The scheme’s emphasis on startups does not mean every requirement has the same age, incubation, recognition, or financial conditions. If a call reserves a category for a particular class of applicant, that call will state the conditions. Do not carry a special condition from a past challenge into a new technology project unless it appears in the current documents.

How the application process works when a call is open

The official TDF project listing checked for this update showed no open feasibility/RFI application, and the listed DPR bids had passed their submission dates. The following is preparation guidance for a future requirement, not an instruction to submit against the archived May 2026 window. Recheck the official listing and linked tender because TDF posts project-specific openings rather than accepting against one permanent annual form.

1. Monitor the official project page

Start at the official TDF project page. Entries may be feasibility/RFI notices or invitations to submit a DPR. Read the project title, stage, technical description, contact details, tender identifier, opening date, last date, and submission link. TDF says its public project information is indicative and directs users to confirm dates, terms, and other relevant details on the DefProc portal or another official source. Use the tender notice as the controlling document for a procurement. If the open-stage list is empty, wait for a posted project that matches your capability; do not treat a closed or historical card as an invitation to apply.

2. Register the organisation

Create the appropriate TDF portal account as an industry applicant before drafting a submission. Have the entity registration, MSME or Startup India recognition, ownership information, authorised signatory details, and technical-area information ready. If you are proposing a consortium, make sure each participant can satisfy the stated rules and that the lead agency is clearly identified.

3. Follow the stage named in the notice

A feasibility/RFI notice is preliminary. The official portal explicitly cautions that an RFI is used to gauge industry capabilities and does not assure a future RFP or funded project. Answer the questions and send information using the route and format in that notice; do not assume that replying makes an organisation a development agency.

For a funded technology project, the current General Guidelines describe a path in which TDF identifies a potential project, conducts a feasibility study where needed, forms a Project Monitoring and Mentoring Group, prepares and approves a Project Definition Document, and issues an RFP requesting DPRs. The DPR is then evaluated under the approved criteria before selection and financial sanction. A posted project notice may describe a specific procurement route or ask for a document at a different point, so follow that notice and its linked documents.

Prepare the technical and financial submissions in the requested formats. Show that the proposed work answers the stated requirement, can meet its performance measures, and has a credible schedule, facilities, team, and testing path. Follow instructions on bid separation, signatures, currency, eligibility declarations, and file labelling exactly. The current request controls the submission contents; sample formats in resource pages are references, not substitutes for the project instructions.

4. Submit before the project closes

Allow time for portal registration, document conversion, signatures, upload checks, and clarification questions. Do not assume a request for an extension will be accepted; the official bidder guidance says extensions are normally not granted and advises against waiting until the final three working days to seek clarification. Keep technical claims, milestones, quotations, and partner commitments consistent across every file.

5. Respond to evaluation and award steps

The current General Guidelines place DPR evaluation and development-agency selection before approval and financial sanction. At project level, the Project Monitoring and Mentoring Group helps prepare the Project Definition Document, evaluates DPRs, monitors progress, reviews deliverables, and mentors the development agency. If selected, the agency works to approved milestones and keeps project and financial records. The award is not complete when the upload button is pressed; testing, reporting, and delivery remain part of the funded work.

Documents and preparation checklist

Before a new project window opens, an applicant can prepare core evidence and then tailor it to the notice. Useful material may include:

certificate of incorporation or applicable firm registration;
MSME, Startup India, or other recognition certificate requested for portal registration;
ownership and resident-control evidence;
consortium or AoP agreement where relevant;
technical capability statement and evidence from previous development or testing;
requirement-specific technical response and performance targets;
project schedule, work packages, staffing, facilities, and test plan;
itemised financial proposal with GST-inclusive quotations;
Project Definition Document response and DPR material in the prescribed formats, when requested;
utilisation, accounting, and milestone-reporting arrangements;
partner letters and defined work shares for academic or research collaborators; and
certificates, licences, security, export-control, or airborne-system approval information where the requirement calls for them.

Only include claims that the organisation can support. TDF may need to assess whether the applicant has the facilities, prior experience, manufacturing route, testing access, and financial controls to execute the project. If a capability depends on a partner, name that dependency and assign the work clearly. If a component requires a certification authority, include that path in the schedule rather than treating certification as an afterthought.

Practical decision rule

This opportunity is worth revisiting when the official portal posts a requirement that matches an existing Indian industrial capability and a measurable defence use. It is a poor fit for a generic software idea, a research-only proposal, a non-profit primary applicant, or a team that cannot provide entity records and cost evidence. It is also a poor fit for anyone expecting an immediate unrestricted cash payment: the official rules describe staged funding, review, documentation, and milestone controls.

For the archived window recorded here, the next action is to wait for an open requirement rather than submit against the expired date. Check the TDF home page, official project listing, General Guidelines, and SOP resources for a newly posted requirement and current rules. The live project listing is the first check for whether applications are open; guidelines explain standing rules, not whether a specific call is accepting submissions. When a new project appears, change this archive status only after its official project card and the linked procurement documents supply a new closing date, eligibility clauses, funding terms, and application instructions. Keep the archived deadline tied to the named feasibility/RFI project so readers can distinguish it from later requirements.
